From df424d95be4db6284cd5f7e7110b119948c840b0 Mon Sep 17 00:00:00 2001 From: Jordan Harband Date: Sun, 8 Nov 2026 22:44:54 -0800 Subject: [PATCH] feat(skills): add eight skills from the coding-agent skills spec Add the skills the spec lists as gaps, each grounded in socket@1.14.1 source, Socket Firewall, socket-mcp, and docs.socket.dev: - socket-firewall: run installs through sfw, read and act on a block, Enterprise wrapper and registry modes, CI and Docker. - socket-pr-alerts: triage Socket for GitHub checks and comments, check reachability, then fix, replace, or accept per PR or for good. - socket-reachability: run full application reachability, read .socket.facts.json, and fix reachable vulnerabilities first. - socket-incident-response: confirm a malware report in the threat feed, find usage and dependency paths, check for install-time execution, contain, rotate secrets, and report. - socket-policy: edit socket.yml and change org alert actions, with dry runs where the API supports them. - socket-sbom: generate CycloneDX locally with cdxgen and export CycloneDX or SPDX for an existing scan. - socket-vet-agent-tools: vet an MCP server, skill, or plugin with existing Socket checks before installing it. - knowledge-update: dated corrections for outdated model knowledge about Socket products. Register them in the Claude marketplace (depending on socket-connect where they need an account), the skill discovery test, and the README, and regenerate the agents README and Codex manifest. --- .claude-plugin/marketplace.json | 55 ++++ README.md | 30 +- agents/README.md | 58 +++- skills/.codex-plugin/plugin.json | 10 +- skills/knowledge-update/SKILL.md | 146 +++++++++ skills/socket-firewall/SKILL.md | 291 ++++++++++++++++++ skills/socket-incident-response/SKILL.md | 281 +++++++++++++++++ skills/socket-policy/SKILL.md | 266 ++++++++++++++++ skills/socket-pr-alerts/SKILL.md | 201 ++++++++++++ skills/socket-reachability/SKILL.md | 227 ++++++++++++++ skills/socket-sbom/SKILL.md | 266 ++++++++++++++++ skills/socket-vet-agent-tools/SKILL.md | 281 +++++++++++++++++ .../structural/paths-skill-discovery.test.mts | 8 + 13 files changed, 2091 insertions(+), 29 deletions(-) create mode 100644 skills/knowledge-update/SKILL.md create mode 100644 skills/socket-firewall/SKILL.md create mode 100644 skills/socket-incident-response/SKILL.md create mode 100644 skills/socket-policy/SKILL.md create mode 100644 skills/socket-pr-alerts/SKILL.md create mode 100644 skills/socket-reachability/SKILL.md create mode 100644 skills/socket-sbom/SKILL.md create mode 100644 skills/socket-vet-agent-tools/SKILL.md diff --git a/.claude-plugin/marketplace.json b/.claude-plugin/marketplace.json index ae9b6af4..a4e4463a 100644 --- a/.claude-plugin/marketplace.json +++ b/.claude-plugin/marketplace.json @@ -80,6 +80,61 @@ "description": "Set up prerequisites for Socket scanning - install the CLI, sign in with your own Socket account, and verify scan access.", "dependencies": ["socket-connect"] }, + { + "name": "socket-firewall", + "source": "./skills/socket-firewall", + "skills": "./", + "description": "Run package installs through Socket Firewall (`sfw`) to block malware at download time, and handle a block when one happens.

Offer the npm wrapper, or the standalone binary below: + +```shell +npm i -g sfw +``` + +The `sfw` npm package downloads the matching Socket Firewall Free binary from GitHub releases, verifies its digest, and caches it. It checks for a newer binary once a day in the background. Set `SFW_SKIP_UPDATE_CHECK=1` to skip that check when a cached binary exists. It runs the binary with your terminal's input and output and exits with the same exit code. + +On Alpine or other musl-based Linux, do not use the npm wrapper. It always downloads the glibc build (`sfw-free-linux-`). Use the `sfw-free-musl-linux-*` standalone binary instead. + +

On macOS, clear the quarantine flag on the unsigned binary: + +```shell +xattr -dr com.apple.quarantine ./path/to/sfw +``` + +On Alpine arm64, install the C++ runtime first: + +```shell +apk add --no-cache libstdc++ libgcc +``` + +Enterprise binaries come from instead (asset names start with `sfw-`, for example `sfw-linux-x86_64`). + +
+ +The only documented flag is `sfw --help`. Do not rely on other flags such as `--version` with the Free binary. If a `sfw --version` check (for example from `/socket-setup`) fails, use `command -v sfw` instead. + +## Step 2: Clear Local Package Caches + +`sfw` only sees network requests. A package already in the local cache installs without a check. Before the first protected install on a machine, or after a scare, clear the cache for the package manager in use: + +| Package manager | Clear the cache | +| --------------- | ---------------------------------------------------------- | +| npm | `npm cache clean --force` | +| yarn v1 | `yarn cache clean` | +| yarn v2+ | `yarn cache clean --mirror` | +| pnpm | `pnpm store prune` (unreferenced packages only; see below) | +| pip | `pip cache purge` | +| uv | `uv cache clean` | +| cargo | `rm -fr ~/.cargo/registry ~/.cargo/git` (everything) | + +`pnpm store prune` keeps packages that any project still references, and those install with no network request, so `sfw` never checks them. For a full re-check, delete `node_modules` and the store directory that `pnpm store path` prints. Ask the user first. + +Ask the user before running the cargo removal. It deletes every cached crate. Cargo's `cargo clean gc -Zgc` removes only unused crates, but it is unstable and needs a nightly toolchain. + +## Step 3: Run Installs Through sfw + +Put `sfw` in front of the package manager command. All arguments pass through unchanged. + +```shell +sfw npm install +sfw npm install --save some-package@1.33.7 +sfw yarn install +sfw pnpm install +sfw pip install requests +sfw uv pip install flask +sfw cargo fetch +``` + +Free supports npm, yarn, pnpm, pip, uv and cargo. Other package managers might work, but support is not guaranteed. + +When this skill is active and the agent runs an install for the user, prefix it with `sfw`. That includes installs done for `/socket-fix`, `/socket-dep-upgrade` and `/socket-dep-replace`. + +To make every install go through the firewall in an interactive shell, add an alias or a function to the shell profile (ask the user before editing their profile). Pick one. Do not add both: the shell expands the alias inside the function definition and the profile fails to load. + +Option A, alias: + +```shell +alias npm="sfw npm" +``` + +Option B, function (use instead of the alias, not with it): + +```shell +npm() { sfw npm "$@"; } +``` + +On PowerShell: + +```powershell +function npm { sfw npm @args } +``` + +To skip the alias for one command, run `command npm install lodash`, or call the package manager by its full path. + +## Step 4: Confirm It Blocks + +Socket publishes test packages that are blocked with the default policy, such as `lodahs` (a mistyped `lodash`). Run the test in a new directory outside the user's project, such as under the system temp directory. Create a `package.json` there first. Without one, npm installs into the nearest parent folder that has a `package.json` or `node_modules`, which could be the user's project. + +```shell +dir="$(mktemp -d)" +cd "$dir" +npm init -y +sfw npm install lodahs +``` + +The install should fail. If it succeeds, one of these happened: + +- The request did not go through the firewall. +- The package came from the local cache (see Step 2). +- The firewall could not reach or parse Socket's API and let the request through. Rerun with `SFW_DEBUG=true` to see errors, and report the result at . More test packages: . + +## Step 5: Read a Block + +When a download is blocked, the firewall returns HTTP **403** and the package manager fails, for example pnpm `ERR_PNPM_FETCH_403` or npm `E403`. Look for these in the output: + +- Free: the package manager shows the 403, and `sfw` prints a Socket Firewall summary. The exact text varies by version. +- Enterprise service mode: `Package blocked for violating organization security policy` (see ) +- Enterprise registry mode: `Access denied: Your download has been blocked by the Socket Security Policy. Reason: Known malware. Please contact your Security Team. Request ID: `. The npm CLI shows this through its `npm-notice` header. The contact sentence can be changed by the firewall admin. If an Artifactory or Nexus instance sits in front of the firewall, it replaces this page with its own 403. + +The exact terminal output varies by version and mode. Free prints a "Protected by Socket Firewall" banner even when nothing is blocked. Enterprise wrapper mode prints nothing extra by default unless a request is blocked or an error occurs. + +
Response headers and JSON report (Enterprise) + +Registry mode adds these response headers: + +- `X-Socket-Decision`: `allowed`, `blocked`, or `fail_open` +- `X-Socket-Block-Reason`: comma-separated alert types, such as `malware,typosquat` +- `X-Socket-Warn-Reason` and `X-Socket-Monitor-Reason` +- `X-Socket-Request-ID`: give this to your security team or Socket support + +In Enterprise wrapper mode, set `SFW_JSON_REPORT_PATH` to write a JSON report of the run: + +```shell +SFW_JSON_REPORT_PATH=./sfw-report.json sfw npm install +``` + +The report's `blocked` array lists each blocked package with a `purlString` (for example `pkg:npm/name@1.0.0`) and a `registryFqdn`. The full schema is not documented, so read only those fields. + +
+ +## Step 6: Decide What to Do After a Block + +1. **Do not bypass the firewall.** Do not rerun the install without `sfw`, with `command npm`, or against a different registry to get around a block. The default policy blocks only **Known Malware**. Possible typosquats and protestware warn by default, and telemetry is monitored. +2. **Identify the package.** Take the name and version from the error, the 403 URL, or the JSON report. Check whether it is a direct dependency or arrives through another package (for npm, `npm ls `). +3. **Look it up.** Run `/socket-inspect` on the package, or open `https://socket.dev//package//overview/`. If a Socket MCP `depscore` or `alerts` tool is available (match the tool by suffix, see `/socket-connect`), use it. +4. **Remove or replace it.** + - Direct dependency: remove it, or use `/socket-dep-replace` to swap in an alternative. + - Transitive dependency: upgrade or replace the parent that pulls it in (`/socket-dep-upgrade`), then install again through `sfw`. +5. **If it was already installed before the firewall was in place**, treat it as a possible compromise and follow `/socket-incident-response`. +6. **If you believe it is a false positive**, report it to support@socket.dev. Enterprise users can also ask their Socket admin to review the org policy (`/socket-policy`). Free has no allow-list. + +Tell the user which package was blocked, why (if the output says), and what you plan to do. Wait for approval before removing or replacing dependencies. + +## Step 7: Enterprise Wrapper Mode (Org Policy) + +Enterprise wrapper mode applies your organization's policy to local installs. It uses the Enterprise binary from `SocketDev/firewall-release` and an API token. Docs: and . + +### 7a. Token + +The token needs the `packages` and `entitlements:list` scopes. The user creates it in the Socket dashboard (see `/socket-setup`, "Creating Tokens") and writes it into the config file themselves. Never ask the user to paste a token into chat, and never print one. + +`sfw` reads the token from the environment or a dotenv-format `.sfw.config` file. The docs use `SOCKET_API_KEY`. `SOCKET_API_TOKEN` and `SOCKET_CLI_API_TOKEN` are also accepted. + +```text +SOCKET_API_KEY= +``` + +Config file lookup: + +- Default: `~/.sfw.config`, then `/run/secrets/dot-env-secrets` +- With `SFW_CONFIG_RELATIVE_PATHS` set: `./.sfw.config`, then parent directories, then the home directory, then `/run/secrets/dot-env-secrets`. Use this for a different token or org per repo. Add `.sfw.config` to `.gitignore` so the token is never committed. + +### 7b. Supported Commands + +Wrapper mode supports npm, yarn, pnpm, pip, pip3, uv, cargo, gem, bundle, dotnet, and go (Linux only). Poetry is not supported. Maven and Gradle need registry mode (Step 8). + +### 7c. Private Registries + +List private registries so the firewall inspects them instead of blocking them as unknown hosts: + +```shell +SFW_CUSTOM_REGISTRIES='npm:packages.example.com/npm-mirror,pypi:packages.example.com/pypi-mirror' +``` + +- Each entry is `kind:fqdn`, `kind:fqdn/url-prefix`, `kind:protocol://fqdn` or `kind:protocol://fqdn/url-prefix`, with no trailing slash. +- Kinds: `npm`, `pypi`, `maven`, `golang`, `gem`, `cargo`, `nuget`. +- Special kinds: `block`; `wrap` (re-encrypts TLS without inspection; the client must trust the sfw CA); `bypass` (no TLS interception, for example for git). + +### 7d. Other Settings + +| Variable | Effect | +| ------------------------------------- | ------------------------------------------------------------- | +| `SFW_UNKNOWN_HOST_ACTION` | `block` (default), `warn`, or `ignore` for unrecognized hosts | +| `SFW_JSON_REPORT_PATH` | Write a JSON report of the run | +| `SFW_REPORT_MESSAGE` | Custom text in the report's "Need help?" section | +| `SFW_TELEMETRY_DISABLED=true` | Turn off telemetry | +| `SFW_HTTP_PORT`, `SFW_HTTPS_PORT` | Proxy ports (defaults 80 and 443) | +| `SFW_ALLOW_BAD_DESTINATION_CERT=true` | Accept invalid upstream certificates | +| `SFW_DEBUG=true` | Debug output | + +## Step 8: Enterprise Registry Mode (Centralized) + +Registry mode is the recommended Enterprise setup for teams. The firewall runs as a Docker container (`socketdev/socket-registry-firewall`), and package managers use it as their registry. No developer needs `sfw` installed. + +- Downstream: clients point straight at the firewall, for example `npm config set registry https://firewall.company.com/npm/`. +- Upstream: Artifactory or Nexus remote repositories point at the firewall. +- It covers npm, PyPI, Maven, Cargo, RubyGems, NuGet, Go, Conda, VS Code Marketplace and OpenVSX, and Hugging Face. +- By default, API errors and unscanned packages are allowed with a warning (fail open). Admins can change both. + +Its own config file is also named `socket.yml`, but it is the firewall's routing config, not the repository policy file the Socket CLI reads. Do not mix them up. + +This is server infrastructure. Do not deploy it for the user. Point the admin to: + +- +- +- +- Artifactory: +- Nexus: +- CodeArtifact: + +## CI and Docker + +Use `/socket-setup` to add the firewall to GitHub Actions, GitLab CI, Bitbucket, other CI systems, and Dockerfiles. In short: the `SocketDev/action` GitHub Action installs `sfw` (`mode: firewall-free`, or `mode: firewall-enterprise` with a `socket-token` secret), and each install step still needs the `sfw` prefix. In CI, use an org API token stored as a secret, never a personal sign-in. + +## Known Limitations + +- Free blocks unrecognized hosts. Private registries such as a company npm mirror fail with a 403 under Free (for example `ERR_PNPM_FETCH_403`). Use Enterprise with `SFW_CUSTOM_REGISTRIES`, or install from that registry without the firewall only after the user agrees. +- Free may block non-registry downloads from hosts it does not recognize, such as tool binaries fetched during an install.

Account authentication and optional global install + +**Optional global install:** If you prefer a global `socket` command, install with `npm install -g socket@latest` (must be version **1.0.0 or higher**). + +#### Authentication + +Commands that require authentication need a Socket account and a credential that you own.

+ + +**Prefer the Socket MCP tools when connected.** Look for tools whose names end in `threat_feed`, `organizations`, `alerts`, `depscore`, `package_files`, `package_file_contents`, and `package_file_grep`. Match on the suffix, never on one hard-coded prefix (see `/socket-connect`, Step 1). If none are present, or a call fails with an authentication error, use `/socket-connect` to sign in through the browser. Never ask the user to paste a token into the chat, and never print one. + +**Plans.** The threat feed is a beta feature that needs extra access on the organization. Do not tell the user which plan includes it. If the CLI, the MCP tool, or the API says the feature is not available (for example a 401 or 403 from the threat feed), say so plainly, link , and continue with the steps that do not need it. Steps 3 to 8 work without the threat feed. + +## Step 1: Collect the Report Details + +Write down what the report says before you search. Ask the user for the link to the report if they have one. + +- Ecosystem (npm, pypi, maven, and so on) +- Package name, including any scope, such as `@scope/name` +- Every bad version. Reports often list more than one. +- When the bad versions were published and when they were removed, if known +- Any indicators the report gives: file names, file hashes, domains, or install hooks +- A known safe version to roll back to + +If the report names only a package and no version, treat every version published after the report's start date as suspect until Step 2 says otherwise. + +## Step 2: Confirm the Report in Socket's Threat Feed + +### 2a. With the MCP tool + +1. Call `organizations` to get the `org_slug`. +2. Call `threat_feed` with `org_slug`, `ecosystem`, `name`, and `version`. Leave `filter` at its default, `mal` (malware, including possible malware). +3. Call it once. The threat feed is Socket's global list of flagged packages; the organization only grants access and does not narrow the results. If the user belongs to several organizations, use any one that has threat feed access. Use Step 3 to check each organization's own exposure. +4. If the response has more results, pass its `endCursor` (or `nextPageCursor`) value as `cursor` to get the next page. + +Use only filter values the API accepts: `mal`, `vuln`, `typo`, `anom`, `spy`, `obf`, `dual`, `joke`, `tp`, `fp`, `u`, `c`. The tool description suggests some other short codes; they are not in the API's list, so do not use them. `obf` and `dual` work only through this tool's `filter`; the CLI cannot request them. + +### 2b. With the CLI + +```shell +pnpm dlx socket threat-feed npm --pkg --version --json --no-interactive --org +``` + +- **Always pass `--json`.** Without it the command opens a full-screen table that takes over the terminal (quit with `q`, `ESC`, or Ctrl-C). `--markdown` opens the same table. +- **Pass `--no-interactive`** so the command does not stop to ask for an organization. +- **Pass the name and version with `--pkg` and `--version`.** Positional arguments are matched against ecosystem and type keywords first, so a package named `mal`, `typo`, or `npm` would be read as a filter. Positional versions also miss prereleases such as `1.0.0-beta.1`. +- **Set the threat type with a positional argument**, such as `typo` in `pnpm dlx socket threat-feed npm typo --json`. In CLI 1.14.1 the value of `--filter` is never read. The CLI type keywords are `mal`, `vuln`, `typo`, `anom`, `spy`, `joke`, `tp`, `fp`, `u`, and `c`. Any other word, including `obf` and `dual`, becomes the package name filter. The CLI also lists `secret`, but the API does not accept it. With no type argument the API default, `mal`, applies. +- The help says the version filter is a prefix match and the package name is a substring match. Check each result's `purl` to make sure it is the package you mean. +- Positional ecosystems are gem, golang, maven, npm, nuget, and pypi. For others, such as cargo, composer, or swift, use `--eco `. +- Set the page size with `--per-page` (alias `--pp`). `--page` is a cursor, not a page number: to get the next page, pass the `endCursor` (or `nextPageCursor`) value from the previous JSON response as `--page `. Sort with `--direction asc` or `--direction desc`. + +The CLI prints `{ "ok": true, "data": { ... } }` on success, and `{ "ok": false, "message": ..., "cause": ... }` with a non-zero exit code on failure. + +### 2c. Read the results + +Each item in `results` has these useful fields: + +| Field | What it tells you | +| ------------------ | ------------------------------------------------------------------------ | +| `purl` | The exact package and version | +| `threatType` | For example `malware`, `possible_malware`, `typosquat`, `false_positive` | +| `description` | Socket's summary of what the package does | +| `createdAt` | When Socket first found the threat | +| `publishedAt` | When the version was published to the registry | +| `removedAt` | When the registry removed it; `null` means it is still there | +| `fileSha256` | SHA-256 of the malicious file; use it as an indicator in Step 5 | +| `needsHumanReview` | `true` means Socket has not confirmed it yet | +| `locationHtmlUrl` | The threat page on socket.dev; share it in the report | + +Use `publishedAt` and `removedAt` as the exposure window. Any install of that version inside the window counts. + +### 2d. If the threat feed is not available + +Check the package version directly. This uses package scoring, not the threat feed: + +```shell +pnpm dlx socket package shallow npm @ --json +``` + +A malicious version shows alerts of type `malware` or `gptMalware` with severity `critical`. The MCP `depscore` tool gives the same kind of answer. For a full package review, use `/socket-inspect`. + +If Socket has no record of the package yet, continue with the details from the report. Socket may not have finished its review. + +## Step 3: Find Out Whether the Project Uses It + +Check every place the package can come from. A clean `package.json` is not enough, because most malicious versions arrive as transitive dependencies. + +1. **Lockfiles.** Search every lockfile in the repo for the package name, then check the versions next to each match: + + ```shell + git ls-files | grep -E '(package-lock\.json|npm-shrinkwrap\.json|pnpm-lock\.yaml|yarn\.lock)$' | xargs grep -n '' + ``` + +2. **Installed packages.** Read the version that is actually on disk. It can differ from the lockfile if someone ran an install without the lockfile: + + ```shell + npm ls --all + ``` + + With pnpm, run `pnpm why `. With Yarn, run `yarn why `. + +3. **Other branches and open pull requests.** A bad version can sit in a feature branch or a Dependabot pull request. Search each branch's lockfiles too. On GitHub, pull requests from forks are not fetched by default, so the second command fetches them under `origin/pr/`: + + ```shell + git fetch --all + git fetch origin '+refs/pull/*/head:refs/remotes/origin/pr/*' + git grep -n '' $(git for-each-ref --format='%(refname)' refs/remotes) -- '*lock*' + ``` + +4. **Other ecosystems.** Some campaigns re-publish the same payload to other registries. For example, one npm worm payload was also re-bundled into a Maven package. Check Python with `pip show ` or `uv tree`, and check any other manifests in the repo. + +5. **Every repo in the organization.** Run `/socket-scan` on each repo you own, or use these: + - The dashboard **Dependency Search** accepts `name`, `name@1.14` (prefix), or `name@1.14.1` (exact). See . + - The campaign page in the dashboard shows how many repos contain the affected versions, with an **Org Impact** tab listing repos and branches. See . + - The MCP `alerts` tool with `artifact_name` set to the package name lists open alerts on it across monitored repos. + - `pnpm dlx socket organization dependencies --json` lists dependencies across monitored repos. It has no name filter, so page through with `--limit` and `--offset` and search the output. + +If none of these find the bad version, the project is not affected now. Still check Step 5 for machines that installed it in the past. + +## Step 4: Find the Dependency Path + +Find which direct dependency pulls the package in. That tells you what to change in Step 6. + +```shell +npm explain +``` + +| Package manager | Command | Docs | +| --------------- | -------------------- | ----------------------------------------------------- | +| npm | `npm explain ` | | +| pnpm | `pnpm why ` | | +| Yarn (Berry) | `yarn why ` | | +| Yarn (classic) | `yarn why ` | | +| uv | `uv tree` | | + +Record each path, for example `my-app > some-lib@2.3.0 > bad-package@1.0.1`. + +## Step 5: Check Whether the Bad Version Was Installed or Ran + +Malware in npm packages usually runs from a `preinstall`, `install`, or `postinstall` script. These run during the install itself, before any code imports the package. See . + +1. **Find every machine that installed it.** Developer laptops, CI runners, build servers, and container images. Check CI logs and lockfile history for installs between `publishedAt` and `removedAt`: + + ```shell + git log -p -S '' -- '*lock*' + ``` + + Search for the bad version, not the name. When a package already in the lockfile moves to the bad version, the count of its name does not change, so `-S ''` misses that commit. Check that each matching hunk belongs to ``. + +2. **See what the bad version ships.** Use the MCP `package_files` tool with the ecosystem, `depname`, and `version`, then `package_file_contents` or `package_file_grep` to read its `package.json` scripts and payload files. This reads the files from Socket. It does not download or run anything. + +3. **Look for the payload on disk.** Search `node_modules`, package manager caches, and home directories for the file names from the report or from `package_files`. Compare file hashes with the `fileSha256` from Step 2: + + ```shell + shasum -a 256 + ``` + +4. **Do not trust a clean install directory.** Some payloads delete themselves after they run and swap in a clean `package.json` to remove the install script. A missing script or a missing payload file does not prove the script never ran. + +5. **Decide.** If the bad version was installed with install scripts enabled, treat that machine and every secret it could read as exposed. Go to Step 7. + +## Step 6: Contain It + +1. **Remove or roll back.** Remove the package, or move to a known safe version. + - If it is a direct dependency, set the safe version in the manifest and reinstall. Use `/socket-dep-upgrade` to upgrade with a security check, or `/socket-dep-replace` to swap it for another package. + - If it is transitive, upgrade the parent from Step 4 to a release that no longer pulls it in, or force a safe version with your package manager's override field: [`overrides`](https://docs.npmjs.com/cli/v11/configuring-npm/package-json#overrides) for npm, [`resolutions`](https://yarnpkg.com/configuration/manifest#resolutions) for Yarn, or the overrides setting in pnpm's docs for pnpm. +2. **Clear local caches.** A cached copy can be reinstalled with no network request, and nothing can block that. Clear the cache on every affected machine with the commands in `/socket-firewall`, Step 2. Ask the user before running any of them. + + `pnpm store prune` removes only packages that no project uses, so run it after the bad version is gone from every project on that machine. + +3. **Reinstall through the firewall.** Run the install as `sfw npm install` (or `sfw pnpm install`, `sfw pip install ...`). Socket Firewall Free blocks confirmed malware at download time. Use `/socket-firewall` to set it up and to read a block. +4. **Block it in policy.** Set the organization's malware alerts to **Block** so `pnpm dlx socket ci` (or `pnpm dlx socket scan create --report`) and pull request checks fail on it. Use `/socket-policy` to read and change the policy, and `/socket-pr-alerts` to handle the pull request side. +5. **Scan again.** Run `/socket-scan`, or create a scan with a report: + + ```shell + pnpm dlx socket scan create . --tmp --report --json --no-banner --no-spinner + ``` + + `--tmp` keeps the scan out of the dashboard, as `/socket-scan` does by default. Drop it only if the user wants the scan saved. Check that no `malware` alerts remain in the report output. + +## Step 7: Rotate Secrets + +Socket does not publish one general rotation guide. The advice below is standard practice. Follow any steps the specific report gives first. + +If Step 5 found that the bad version was installed with scripts enabled: + +1. List every secret the affected machine or CI job could read: environment variables, `.npmrc` and other registry tokens, Git and GitHub tokens, cloud credentials, SSH keys, and CI secrets. +2. Revoke each one and issue a new one. Do this from a clean machine. +3. Check the logs of each service for use of the old credentials during the exposure window. +4. If a registry publish token was exposed, check the account's recent releases for versions nobody published on purpose. Consider moving to trusted publishing, which removes long-lived publish tokens. +5. Rebuild affected CI runners and containers from a clean image. + +Never ask the user to paste a secret into the chat, and never print one while checking. + +## Step 8: Report + +Write a short summary for the team: + +```text +Incident: / +Source: , +Affected: , or "not affected" +Dependency path: +Installed or ran: yes / no / unknown, and on which machines +Contained by: +Secrets rotated: +Follow-up: +``` + +If Socket's verdict looks wrong, send the false positive or false negative to support@socket.dev. + +## Error Handling + +- **Threat feed returns 401 or 403**: the token may lack the `threat-feed:list` permission, or the organization may not have threat feed access.

A firewall cannot block a cached copy. +- Use `--json` and `--no-interactive` with `pnpm dlx socket threat-feed`.

Prefer the organization policy for anything that should apply to more than one repo. + +## Step 2: Find the Existing File + +Look in the repository root for `socket.yml`, then `socket.yaml`. The docs say the file belongs in the repository root. If both exist, `socket.yml` wins. + +The CLI searches more widely: it starts in the current directory and walks up to the filesystem root, and in each directory it tries `socket.yml` before `socket.yaml`. Running the CLI from a subfolder can pick up a different file than the GitHub App does. Keep a single file at the repository root. + +If the file has no `version` key and uses `ignore`, `issues`, `beta`, or top-level `enabled` keys, it is version 1. Migrate it: + +1. Add `version: 2` +2. Rename `ignore` to `projectIgnorePaths` +3. Rename `issues` to `issueRules` +4. Move `enabled`, `projectReportsEnabled`, and `pullRequestAlertsEnabled` under `githubApp` +5. Remove `beta` + +## Step 3: Write socket.yml + +Start from this example from the Socket docs and remove what the user does not need: + +```yaml +version: 2 +projectIgnorePaths: + - 'ignored-folder' + - 'foo/bar/package.json' +triggerPaths: + - 'package.json' + - 'package-lock.json' +issueRules: + unresolvedRequire: false +githubApp: + enabled: true + dependencyOverviewEnabled: true + ignoreUsers: ['aBotOnGitHub'] + disableCommentsAndCheckRuns: false +``` + +### Keys + +- `version` (required): set it to `2`. +- `projectIgnorePaths`: list of gitignore-style patterns for paths Socket skips. Socket always ignores `.git`, `.log`, `.nyc_output`, `.sass-cache`, `.yarn`, `bower_components`, `coverage`, and `node_modules`. Quote any pattern that uses `!` or `*`. +- `triggerPaths`: gitignore-style patterns, default `["*"]`. The GitHub App runs a PR alert scan only when a file changed in the PR matches. The CLI ignores this key. +- `issueRules`: map of alert type to `true` or `false`. **Deprecated**: Socket plans to replace it with repository labels and Policies. Alert types you leave out follow the organization settings. +- `githubApp.enabled`: default `true`. `false` turns the GitHub App off for this repo and overrides the other `githubApp` settings. +- `githubApp.pullRequestAlertsEnabled`: default `true`. +- `githubApp.dependencyOverviewEnabled`: default `true`. It needs `enabled` and `pullRequestAlertsEnabled`. +- `githubApp.projectReportsEnabled`: default `true`. +- `githubApp.ignoreUsers`: list of GitHub users whose PRs the app skips. Default `[]`. +- `githubApp.disableCommentsAndCheckRuns`: default `false`. Overrides the organization setting for this repo. + +The schema package also accepts `githubApp.authenticatedProjectReports`, but the docs do not describe it. Do not add it unless the user asks. + +For GitLab, the GitLab app (beta) reads only `projectIgnorePaths` and `gitlabApp.enabled`, `gitlabApp.dependencyOverviewEnabled`, `gitlabApp.pullRequestAlertsEnabled`, and `gitlabApp.commitStatusEnabled`. Keep `version: 2` so the CLI and the GitHub App still accept the file. + +### What the CLI uses + +- `pnpm dlx socket scan create`, `pnpm dlx socket scan reach`, and `pnpm dlx socket fix` apply `projectIgnorePaths` when they collect manifest files. The CLI reads the patterns as a .gitignore at the project root. +- The package manager wrappers (`pnpm dlx socket npm`, `pnpm dlx socket npx`, `pnpm dlx socket pnpm`) apply `issueRules`. `false` hides that alert type. `true` does not bring back an alert type the organization policy ignores, because the wrappers never receive those alerts. These wrappers are the older install path; for blocking at install time, prefer `sfw` (see `/socket-firewall`). +- For a one-off scan, `pnpm dlx socket scan create --exclude-paths ` excludes paths without editing the file. Its patterns are anchored globs relative to the current directory and do not support `!` negation, so they differ from `projectIgnorePaths`. + +## Step 4: Check the File + +The Socket CLI has no command that validates `socket.yml`. Check it yourself: + +1. Make sure the YAML parses and `version: 2` is present. +2. Compare every key against the list in Step 3. Watch for typos: the CLI's parser (`@socketsecurity/config`) **silently drops** keys it does not know. It does not report them. +3. Know that the CLI's parser only knows `version`, `projectIgnorePaths`, `issueRules`, and `githubApp` with `enabled`, `ignoreUsers`, `projectReportsEnabled`, `pullRequestAlertsEnabled`, `dependencyOverviewEnabled`, and `authenticatedProjectReports`. It drops `triggerPaths`, `githubApp.disableCommentsAndCheckRuns`, and `gitlabApp` too, but those keys are documented and the GitHub or GitLab app reads them. A clean parse does not prove every key took effect. +4. If the project already has `@socketsecurity/config` installed, parse the file with it. The call throws on bad YAML, and throws an error with a `validationErrors` list when the content does not match the schema: + +```shell +node -e "require('@socketsecurity/config').parseSocketConfig(require('fs').readFileSync('socket.yml', 'utf8')); console.log('ok')" +``` + +Do not install packages just to run this check. If the package is not present, check by hand. + +If the CLI cannot parse `socket.yml`, it treats the repo as if it had no file and keeps going. No error stops the scan. If ignored paths still show up in scan results, the file probably failed to parse. + +## Step 5: Read the Organization Policy + +The hosted Socket MCP tools from `/socket-connect` do not expose policy settings. Use the CLI after the user signs in with `/socket-connect`: + +```shell +pnpm dlx socket organization policy security --org +pnpm dlx socket organization policy license --org +``` + +- `policy security` prints the default policy setting and a table of alert types and their actions. It needs the `security-policy:read` scope. Add `--json` for machine-readable output. +- `policy license` prints a table of licenses and whether each is allowed. It needs the `license-policy:read` scope. +- Both commands read the legacy policy endpoints. After an organization moves to the new Policies model, those endpoints become a frozen archive, so the output may not match the live policy. The CLI has no command for the new alert policies. + +To see how a scan fares against the policy, use `/socket-scan`, or run a report on an existing scan: + +```shell +pnpm dlx socket scan report --short +``` + +It prints `OK` or `ERR`, and exits with code 1 when any alert in the scan has the Block (`error`) action. `--report-level` changes which alerts are listed, not the exit code. + +`scan report` checks the scan against the legacy security policy. After an organization moves to Policies, it still uses the archived legacy policy, so its `OK` or `ERR` may not match the live policy. + +## Step 6: Change Alert Actions + +Socket has four alert actions: + +| Action | API value | Effect | +| ------- | --------- | -------------------------------------------------------------------- | +| Block | `error` | Shown to developers. Fails the PR check; the CLI exits with an error | +| Warn | `warn` | Shown to developers in PR comments and CLI warnings | +| Monitor | `monitor` | Not shown to developers in PR comments or CLI warnings | +| Ignore | `ignore` | The alert is ignored | + +### Policies model + +Socket is moving organizations to Policies (). A policy starts from a baseline preset (Essential, Balanced, Comprehensive, or None) and adds an ordered list of rules. The first matching rule wins. Each repo belongs to exactly one policy through a repository label. Socket Firewall (see `/socket-firewall`) uses the Default policy.

Check the YAML and keys (Step 4). Also check that the CLI ran from inside the repo, since it walks up from the current directory. +- **A key has no effect in the CLI**: the CLI drops unknown keys, and it never reads `triggerPaths` or `disableCommentsAndCheckRuns`. Those apply only in the GitHub App. +- **403 from a policy endpoint**: the token is restricted to some repos, or lacks the scope. The user needs an organization-wide token with the right scope. +- **409 from a policy endpoint**: one of three causes. A policy or rule write before the migration is confirmed, a legacy security-policy write after it, or a duplicate policy name. Check the migration status endpoint (Step 6). +- **Feature not available on the plan**: tell the user plainly that Socket says the feature is not on their plan, and point them to . Do not guess which plan includes it. +- **401 or not signed in**: use `/socket-connect`. + +## Tips + +- Keep one `socket.yml` at the repository root. Do not add one per package in a monorepo. +- Set org-wide alert actions in the organization policy, not in each repo's `issueRules`. `issueRules` is deprecated. +- Quote glob patterns in YAML, especially ones with `*` or `!`. +- Re-read the file after editing: a misspelled key fails silently. +- Dry-run every alert-policies and rules write and show the result before the real write. Legacy security-policy writes have no dry run: show the body and ask first. +- To fix the alerts a policy surfaces, use `/socket-fix`, `/socket-dep-upgrade`, `/socket-dep-patch`, or `/socket-dep-replace`.

Its details link opens the report in the Socket dashboard. `githubApp.projectReportsEnabled: false` in `socket.yml` turns it off, so it may be missing. | + +List the checks on the PR: + +```shell +gh pr checks -R / --json name,state,bucket,link,workflow +``` + +For the check output, get the head commit and read the check runs from the `socket-security` app: + +```shell +gh pr view -R / --json headRefOid -q .headRefOid +gh api repos///commits//check-runs?per_page=100 --paginate --jq '.check_runs[]|select(.app.slug=="socket-security")|{name,conclusion,details_url,title:.output.title,summary:.output.summary}' +``` + +Trust `conclusion`, not the title. A failing Pull Request Alerts check can still have a title that ends in "Complete with warnings". + +If the check is **Neutral**, tell the user the results may be incomplete before triaging anything. + +## Step 2: Read the Socket Comments + +Socket posts its comments on the main PR thread as `socket-security[bot]`: + +```shell +gh api repos///issues//comments --paginate --jq '.[]|select(.user.login=="socket-security[bot]")|.body' +``` + +There are usually two comments: + +1. **Dependency overview.** Starts with "Review the following changes in direct dependencies." It is a table of added and updated direct dependencies with Supply Chain Security, Vulnerability, Quality, Maintenance and License scores. It is context, not a list of problems. +2. **Alerts.** A table with Priority, Alert and Action columns. The Priority icon shows a priority score, such as "Priority 140 (Low)". It is not the alert's severity. The PR comment does not show severity; get it from the alert page or from `depscore`. Each alert is a collapsible block with: + - the alert title, the ecosystem, and the package + - **From:** the dependency path that pulls the package in + - links to the package, the alert, and the alert type's page under `https://socket.dev/alerts/` + - next steps, a suggestion, and the exact ignore command for that package + +If a row says "See N more rows in the dashboard", the comment is truncated. Open the "View full report" link at the end of the comment to see every alert. + +The PR shows only alerts whose action is **Block** or **Warn**: + +| Action | On the PR | Fails the check | +| ------- | --------- | --------------- | +| Block | yes | yes | +| Warn | yes | no | +| Monitor | no | no | +| Ignore | no | no | + +The organization's security policy sets the action for each alert type, so the same alert can be Block in one organization and Warn in another. + +## Step 3: Understand Each Alert + +Socket groups alerts into five categories: Supply chain risk, Vulnerability, Quality, Maintenance and License. Each has Critical, High, Medium and Low severities. See [package issues](https://docs.socket.dev/docs/package-issues) and the [alert list](https://socket.dev/alerts). + +| Category and severity | What it means | +| ----------------------- | ---------------------------------------------------------------- | +| Supply chain, Critical | Known malware, typosquats, HTTP dependencies and similar threats | +| Supply chain, High | Unsafe until someone inspects it | +| Vulnerability, Critical | Update to a fixed version now | +| Vulnerability, High | Update as soon as you reasonably can | +| License, Critical | Replace the package now | +| License, High | Needs legal review | + +For more detail on a package, use `/socket-inspect`. With the Socket MCP server connected, find the `depscore` tool by its suffix and call it for the package. To read the package's code behind an alert such as Obfuscated code or Install-time scripts, use the `package_files`, `package_file_contents` and `package_file_grep` tools. + +## Step 4: Check Reachability on the Alert Details Page + +The Priority icon in each alert row, and the "This alert" link in the alert's block, open that alert in the PR's diff scan in the Socket dashboard. Reachability dependency chains are on the **Alert Details** page for the organization's alerts in the dashboard. That page shows: + +- an overview of the alert: what it is, its severity and category +- detected instances, sorted by a priority score that uses reachability, fixability and other factors +- reachability dependency chains: the path from the project's code to the vulnerable package, and where reachability stops +- the alert's status, triage action and notes + +For a vulnerability, the chain answers three questions: is it reachable, which dependency brings it in, and what to update to remove it. See [the Alert Details page](https://socket.dev/blog/introducing-the-alert-details-page) and [reachability results](https://docs.socket.dev/docs/reachability-results). + +The dashboard shows a label. The API returns the type in parentheses. + +| Verdict | What to do | +| ----------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | +| Reachable (`reachable`) | Fix it | +| Potentially reachable (`maybe_reachable`) | A chain exists from a direct dependency down to the package. Treat it as reachable | +| Unreachable (`unreachable`) | No path to the vulnerable code was found. Lower priority; accepting it is reasonable if you record why. It is not proof the package is safe | +| Pending precomputation (`pending`) | Needs a new scan | +| Direct Dependency (`direct_dependency`) | Precomputed analysis cannot judge direct dependencies. Treat it as reachable | +| Not yet supported (`missing_support`), Not determinable (`undeterminable_reachability`), Unknown (`unknown`), Error (`error`) | No verdict. Treat it as possibly reachable, not as safe | + +The dashboard needs a login. If the agent cannot open a page, give the user the link and ask what the page shows. To run full application reachability yourself, use `/socket-reachability`. If the CLI or dashboard says reachability is not available on the user's plan, tell the user plainly and point to . + +## Step 5: Decide Fix, Replace, or Accept + +Follow [Socket's guidance](https://docs.socket.dev/docs/what-to-do-with-socket-alerts) for each alert: + +| Alert | Decision | +| -------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------- | +| Known malware, protestware or troll | Remove the package now and pick a different one: `/socket-dep-replace`. For a malware campaign, also see `/socket-incident-response` | +| Potential typosquat | Confirm the package is the one the user meant. If not, replace it | +| Vulnerability with a fixed version, reachable or unknown | Upgrade: `/socket-fix` for the fix flow, or `/socket-dep-upgrade` for one package. Use `/socket-dep-patch` when no upgrade is possible | +| Vulnerability that is unreachable | Accepting the risk is reasonable. Record why | +| Install scripts or native code | Audit the package source before accepting | +| Telemetry | Follow the alert's instructions to turn it off | +| License, High or Critical | Get a legal review, or replace the package | +| The same harmless alert keeps showing up across PRs | Change the policy: `/socket-policy` | + +When the alert comes from a transitive package, the **From:** path in the comment or the dependency chain on the Alert Details page names the direct dependency to upgrade or replace. + +Present the decisions to the user as a short table: package, alert, action, severity, decision, and reason. Let the user confirm before changing code. + +## Step 6: Accept an Alert on This PR Only + +To accept an alert for this PR only, a repository contributor posts a comment on the main PR thread. The command must be the very first thing in the comment: + +```text +@SocketSecurity ignore npm/@ +``` + +Use the exact command from the alert's own block in the Socket comment. It names the ecosystem, package and version. To ignore every alert on the PR: + +```text +@SocketSecurity ignore-all +``` + +- Ignoring reruns the PR alert report without the ignored package. +- To undo it, edit or delete the comment that ignored the package. +- The command applies to this PR only. The same alert comes back on future PRs. + +Posting the comment sends a message as the user. Draft the comment, show it, and ask before posting. After the user approves, post it: + +```shell +gh pr comment -R / --body '@SocketSecurity ignore npm/@' +``` + +See [ignoring pull request alerts](https://docs.socket.dev/docs/ignoring-pull-request-alerts). + +## Step 7: Accept an Alert for All Future PRs + +To accept an alert beyond this PR, change its triage state in the dashboard, or create an **alert resolution**. A resolution records a reason (Remediated, False positive, Tolerable risk, or Other) and a scope. Future alerts that match the scope are resolved automatically. Resolutions are checked before policy rules. + +- Use the narrowest scope: this repository, this package and version, and this alert type. +- An org-wide scope on alert type only is rarely what you want. +- To undo a resolution, delete it. + +The resolution API is documented at [alert resolutions](https://docs.socket.dev/docs/alert-resolutions), with a dry-run mode for writes. A resolution changes shared state for the organization, so confirm the scope and reason with the user before creating one. + +To change how a whole class of alerts is handled, for example to move an alert type from Block to Warn, use `/socket-policy` instead. + +## Step 8: Hand Off and Re-check + +1. Hand each "fix" or "replace" decision to the matching skill: `/socket-fix`, `/socket-dep-upgrade`, `/socket-dep-replace`, or `/socket-dep-patch`. +2. Push the changes to the PR branch. Socket scans again on every push. +3. Repeat Step 1 until `Socket Security: Pull Request Alerts` passes, or every remaining alert has a recorded decision. + +To make this check required before merging, add `Socket Security: Pull Request Alerts` as a required status check in branch protection. See [enable branch protection](https://docs.socket.dev/docs/enable-branch-protection). + +## Error Handling + +- **No Socket checks or comments on the PR**: Socket for GitHub may not be installed, the PR may not change a manifest or lockfile, `socket.yml` (or `socket.yaml`) may turn PR alerts off (`githubApp.enabled`, `githubApp.pullRequestAlertsEnabled`, `githubApp.disableCommentsAndCheckRuns`, `triggerPaths`, or `githubApp.ignoreUsers` for bot authors), or the organization setting "Disable Comments and Check Runs" may be on and not overridden in that file. Check the file at the repository root, ask an organization admin about the setting, or use `/socket-setup`. +- **The ignore command did nothing**: Check that the command is the first thing in the comment, that it is on the main PR thread and not a review comment, and that the author is a repository contributor. +- **`gh` returns 401 or 404**: The account cannot read the repository. Ask the user to sign in with `gh auth login` in their own terminal. +- **A Socket tool needs authentication**: Use `/socket-connect`. Do not ask for a token in the chat. + +## Tips + +- Read every alert before ignoring anything. `@SocketSecurity ignore-all` hides every alert on the PR, including ones nobody has read. +- Never ignore malware or a typosquat. Remove the package. +- Prefer a narrow resolution over a policy change, and a policy change over repeated ignore comments. +- The Socket MCP `alerts` tool lists the organization's latest alerts, not the alerts on one PR. Use the PR comment for PR triage. +- The CLI has no command to ignore or resolve alerts. Use the PR comment or the dashboard. +- Use `/socket-scan` to scan locally before pushing, and `/socket-firewall` to block bad packages at install time. +- Socket's documentation index for agents is at . diff --git a/skills/socket-reachability/SKILL.md b/skills/socket-reachability/SKILL.md new file mode 100644 index 00000000..9dd36c67 --- /dev/null +++ b/skills/socket-reachability/SKILL.md @@ -0,0 +1,227 @@ +--- +name: socket-reachability +description: Run Socket full application reachability analysis and read the + .socket.facts.json report it writes.

Add `--reach-retain-facts-file` if you need to read the report afterward. A failed scan keeps the file for debugging. + +Both commands take exactly one target directory. It must exist and must be inside the current working directory. + +## Step 3: Run the Analysis + +Report only, for the current directory: + +```shell +pnpm dlx socket scan reach . --org --json --no-banner --no-spinner 2>/dev/null +``` + +In `--json` mode the engine's own log goes to stderr, so `2>/dev/null` leaves clean JSON on stdout. On success the output looks like this: + +```json +{ "ok": true, "data": { "reachabilityReport": ".socket.facts.json" } } +``` + +`data` may also carry a `tier1ReachabilityScanId`. On failure the output is `{ "ok": false, "message": "...", "cause": "..." }` and the exit code is non-zero. Show the user `message` and `cause`. + +Write the report somewhere else with `--output` (the path must end in `.json`): + +```shell +pnpm dlx socket scan reach ./proj --output ./reports/analysis.json +``` + +Reachability plus a dashboard scan, keeping the report. Run this only when the user explicitly asks to save the scan to the Socket dashboard; otherwise use `scan reach` above: + +```shell +pnpm dlx socket scan create . --reach --reach-retain-facts-file --org --json --no-banner --no-spinner +``` + +Every `--reach-*` flag on `scan create` requires `--reach`. + +
Useful reachability flags + +These work on both commands unless noted.

Values: `cargo`, `composer`, `gem`, `golang`, `maven`, `npm`, `nuget`, `pypi` | +| `--reach-advisories ` | all | Check only these advisories. CVE IDs are converted to GHSA. Others get `unknown` | +| `--reach-analysis-timeout
+ +## Step 4: Read `.socket.facts.json` + +The report is written to the scan's working directory as `.socket.facts.json`, unless `--output` named another path. Do not confuse this file with build-generated SBOM files such as `pom.xml.socket.facts.json` or `gradle.socket.facts.json`. Those are inputs, not reachability reports. + +There is no published, versioned schema for this file. The CLI itself reads only these fields: + +```text +{ + tier1ReachabilityScanId?: string, + components: [{ + name, version, + reachability?: [{ + ghsa_id, // snake case here + reachability: [{ type, workspacePath, subprojectPath }] + }] + }] +} +``` + +`subprojectPath` is the build root (`.` for a single-root repo). `workspacePath` is the workspace inside it. + +Other fields appear in the CLI's test fixtures only, so they may change. Each component can carry `type` (the purl type, such as `npm`) and `vulnerabilities: [{ ghsaId, severity, range }]` (camel case here). Each reachability entry can carry `analysisLevel` and `matches`. `matches` is an array of call chains. Each chain is an array of `{ package, sourceLocation: { filename, start, end }, confidence }`, where `start` and `end` have `line` and `column`. Inspect the real file before relying on these fields. + +List every advisory with its reachability type, one line each: + +```shell +node -e ' +const f = require(require("path").resolve(process.argv[1])); +for (const c of f.components ?? []) { + for (const r of c.reachability ?? []) { + for (const e of r.reachability ?? []) { + console.log([e.type, r.ghsa_id, `${c.name}@${c.version}`, e.subprojectPath, e.workspacePath].join("\t")); + } + } +}' .socket.facts.json | sort +``` + +## Step 5: Triage by Reachability + +Group findings by `type`.

Expect `reachable`, `unreachable` and `error` most often in a local report. + +Report to the user: + +1. Reachable advisories, with package, version, workspace, and the call sites from `matches` when present. +2. Undecided advisories (`unknown`, `error`, `undeterminable_reachability`, `missing_support`). +3. A count of unreachable advisories. Do not call them safe; say they were not reached in this analysis. + +The engine also warns in text mode about each failed advisory as ` in @ ()`. Include those under undecided. + +## Step 6: Fix Reachable Vulnerabilities First + +Hand the reachable advisory IDs to `/socket-fix`. Its `--id` flag accepts GHSA IDs, CVE IDs, or PURLs, repeated or comma-separated. Preview first: + +```shell +pnpm dlx socket fix --id GHSA-xxxx-xxxx-xxxx,GHSA-yyyy-yyyy-yyyy --no-apply-fixes --json +``` + +Let `/socket-fix` apply the changes and verify them. When no fixed version exists, use `/socket-dep-patch` for a Socket patch or `/socket-dep-replace` for a replacement package. Use `/socket-inspect` to look into a flagged package. After fixing, re-run Step 3 and confirm the advisories are gone. + +## Step 7: Clean Up the Report + +Delete `.socket.facts.json` when you are done with it, unless the user wants to keep it: + +```shell +rm .socket.facts.json +``` + +A plain `pnpm dlx socket scan create` without `--reach` uploads a leftover `.socket.facts.json` as an SBOM, with stale reachability results.

+ + +Local generation with `pnpm dlx socket cdxgen` needs no account. Scan reports and the license policy need a signed-in CLI or an API token. Use `/socket-connect` to sign in: the user runs `pnpm dlx socket login` in their own terminal. + +The API export in Step 3 is different. `pnpm dlx socket login` alone is not enough for it, because the CLI keeps its token in its own config and no CLI command calls the export endpoints. The user needs an organization API token with the `report:read` scope, set as `SOCKET_CLI_API_TOKEN` in their own shell. Never ask the user to paste a token into the chat, and never print one. + +The hosted Socket MCP server has no SBOM or license-report tool. For license alerts on a few specific packages, use the MCP tool whose name ends in `alerts` with category `license` (match tools by suffix, see `/socket-connect` Step 1), or use `/socket-inspect`. Use the CLI and the REST API for whole-project SBOMs and policy reports. + +## Step 1: Pick the Path + +Ask what the SBOM is for, then pick: + +| Need | Path | +| -------------------------------------------------------- | ----------------------- | +| A CycloneDX file built from the code on disk, no account | Step 2 (local cdxgen) | +| An SPDX file | Step 3 (API export) | +| The SBOM of a scan Socket already ran | Step 3 (API export) | +| Pass/fail against the license policy | Step 4 (scan report) | +| The list of allowed and denied licenses | Step 5 (license policy) | +| Feed an existing SBOM into a Socket scan | Step 6 (import) | + +Local generation writes CycloneDX only.

Upstream cdxgen writes `bom.json`. +- **Project type:** `js` unless you pass `-t` or `--type`. Pass `-t` once per ecosystem in a mixed repo. +- **Lifecycle:** `pre-build` with `--install-deps false` unless you pass `--lifecycle`. This avoids running package install scripts. Passing `--lifecycle build` adds build-time data but runs project code again. Ask the user before you use it. + +Common commands: + +```shell +# Java project +pnpm dlx socket cdxgen -t java . + +# Java and JavaScript, named output, pretty JSON, CycloneDX 1.6 +pnpm dlx socket cdxgen -t java -t js -o sbom.cdx.json --spec-version 1.6 --json-pretty . + +# License-focused profile +pnpm dlx socket cdxgen --profile license-compliance -t js . + +# cdxgen's own help, including the pinned cdxgen version +pnpm dlx socket cdxgen --help +``` + +
Argument rules and forwarded flags + +- The target path must be `.` or start with `./`, `../`, or `/`. A bare name such as `proj` is rejected as an unknown argument. Write `./proj`. +- Only flags Socket knows are forwarded. Unknown flags exit with code 2 and print `Unknown argument(s): ...`. `--project-tag`, `--include-regex`, and `--exclude-regex` are rejected. Use `--exclude` with a glob instead of `--exclude-regex`. +- `-c` is Socket's own `--config` flag. Use `--resolve-class` for cdxgen's class resolution. +- `-p` / `--print` prints the SBOM as a table with a tree. It does not write the SBOM to stdout. +- `--spec-version` takes 1.4, 1.5, 1.6, or 1.7. The default is 1.6. +- `--profile` takes values such as `generic` (the default), `license-compliance`, `appsec`, `research`, `operational`, `threat-modeling`, and `ml`. +- Other forwarded flags: `--exclude-type`, `-r` / `--recurse` (on by default; `--no-recurse` turns it off), `--deep`, `--required-only`, `--fail-on-error`, `--no-babel`, `--install-deps`, `--validate` / `--no-validate`, `--evidence`, `--filter`, `--only`, `--author`, `--include-formulation`, `--include-crypto`, `--standard`, `--min-confidence`, `--technique`, `--auto-compositions`, `--generate-key-and-sign`, `--export-proto`, `--proto-bin-file`, and the server flags `--server`, `--server-host`, `--server-port`. +- Dependency-Track upload flags: `--server-url`, `--api-key`, `--project-group`, `--project-name`, `--project-version`, `--project-id`, `--parent-project-id`, `--skip-dt-tls-check`. Do not put a Dependency-Track key on the command line in chat. Ask the user to run that upload themselves. + +
+ +On success the CLI logs `socket-cdx.json created!` (or your output name). The exit code is cdxgen's exit code. + +Read the result. It is a CycloneDX JSON document: + +- `components[]`: each has `name`, `version`, `purl`, `scope`, `hashes`, `bom-ref`, and `licenses[]`. A license entry is `{"license": {"id"|"name"|"url"}}` or `{"expression": "..."}`. +- `dependencies[]`: each has `ref` and `dependsOn`. + +Tell the user that a local SBOM is an inventory only. It has no Socket alerts, malware checks, or scores. Use `/socket-scan` for that. + +## Step 3: Export an SBOM for an Existing Socket Scan + +The Socket API exports a full scan as CycloneDX or SPDX. Both endpoints are marked Beta. No `pnpm dlx socket` command calls them, so use the REST API. + +First get the scan ID. `pnpm dlx socket scan create` prints it, or list recent scans: + +```shell +pnpm dlx socket scan list --json +pnpm dlx socket scan list my-repo main --json +``` + +Get the organization slug from the `slug` field of each organization in the JSON output (or from the MCP tool whose name ends in `organizations`): + +```shell +pnpm dlx socket organization list --json +``` + +Set `ORG` to the slug and `SCAN_ID` to the scan ID in the shell. Then call the export endpoint. `SOCKET_CLI_API_TOKEN` must already be set by the user in their own shell. The endpoints need the `report:read` scope and cost 1 quota unit each. + +`--fail-with-body` makes curl exit non-zero on an HTTP error such as 401, 403, 404, or 429. Without it, curl exits 0 and writes the API's JSON error into the output file. On failure, show the error body and delete the file. + +```shell +# CycloneDX +curl -sS --fail-with-body -u "$SOCKET_CLI_API_TOKEN:" \ + "https://api.socket.dev/v0/orgs/$ORG/export/cdx/$SCAN_ID" -o socket-sbom.cdx.json \ + || { cat socket-sbom.cdx.json; rm -f socket-sbom.cdx.json; } + +# SPDX, with vulnerability data +curl -sS --fail-with-body -u "$SOCKET_CLI_API_TOKEN:" \ + "https://api.socket.dev/v0/orgs/$ORG/export/spdx/$SCAN_ID?include_vulnerabilities=true" -o socket-sbom.spdx.json \ + || { cat socket-sbom.spdx.json; rm -f socket-sbom.spdx.json; } +``` + +Before you treat the file as an SBOM, check its contents. A CycloneDX export has `bomFormat` and `components`. An SPDX export has `spdxVersion`. If those are missing, the file holds an error, not an SBOM. + +Query parameters, all optional strings: + +- `include_vulnerabilities`: `true` adds vulnerability data, and reachability or VEX data when available. Default `false`. +- `author`: SBOM author. Default `OWASP Foundation`. +- `project_group`, `project_name`, `project_version`, `project_id`: Dependency-Track project fields. + +Notes: + +- Exported ecosystems: crates, go, maven, npm, nuget, pypi, rubygems, spdx, cdx. Packages from other ecosystems are left out of the export. Say so when the project uses one. +- The SPDX export is SPDX 2.3 JSON with `packages[]`. The CycloneDX export has `components[]`, `dependencies[]`, and `vulnerabilities[]`. +- An OpenVEX export also exists: . +- For a CSV of a scan's alerts with license details, see . + +If `SOCKET_CLI_API_TOKEN` is not set, do not ask for the token in chat. Offer the local SBOM from Step 2, or ask the user to set the variable in their own shell. + +## Step 4: Check a Scan Against the License Policy + +`pnpm dlx socket scan report` checks a scan against the organization's policies. By default it checks only the security policy. Add `--license` to also check the license policy. The security check uses the legacy security policy, so after an organization moves to the new Policies model its result may not match the live policy (see `/socket-policy`, Step 5). + +```shell +pnpm dlx socket scan report --license --markdown +pnpm dlx socket scan report --license --json --fold=version +pnpm dlx socket scan report --license --markdown --short +pnpm dlx socket scan report --license report.md +``` + +- `--fold none|pkg|version|file` groups alerts. Default `none`. +- `--report-level defer|ignore|monitor|warn|error` sets the lowest level to report. Default `warn`. +- `--short` prints only the health result. +- An output path ending in `.json` or `.md` picks the format. `-` means stdout. +- The command exits with code 1 when the scan is not healthy. + +`pnpm dlx socket scan create --report` creates a scan, waits, and runs the same report with the license policy included. Use it when there is no scan yet. + +License problems appear as alerts. Common types: + +| Severity | Alert | +| -------- | ---------------------------- | +| Critical | License Policy Violation | +| High | Explicitly Unlicensed Item | +| Medium | Misc. License Issues | +| Low | Copyleft License | +| Low | No License Found | +| Low | Non-permissive License | +| Low | Unidentified License | +| Low | Ambiguous License Classifier | +| Low | License exception | + +For a per-package license list, view the raw scan: + +```shell +pnpm dlx socket scan view --json scan.json +``` + +Each artifact has a `license` field. The full-scan API adds `licenseDetails` and `licenseAttrib` when called with `include_license_details`. + +## Step 5: Show the Organization's License Policy + +```shell +pnpm dlx socket license +pnpm dlx socket organization policy license --json +``` + +Text output is a table of license names and whether each is allowed. Use `--json` for the full result. The token needs the `license-policy:read` scope. + +Explain the default: any license not set in the policy is treated as denied. New or unknown licenses therefore fail until someone moves them to Monitor or Allow. The policy is changed in the dashboard under **Settings > Legal**. The CLI cannot change it. Use `/socket-policy` for policy changes. + +## Step 6: Load an Existing SBOM Into a Socket Scan + +The full-scan API accepts CycloneDX uploads. The docs use `bom.cdx.json` as the file name. + +- `pnpm dlx socket scan create` picks up pre-generated CycloneDX and SPDX files whose names match the patterns the API lists at . +- `pnpm dlx socket scan create --reach --reach-use-only-pregenerated-sboms` builds the scan only from pre-generated CycloneDX and SPDX files in the project. See `/socket-reachability`. + +The CLI's own SBOM uploads use names ending in `cdx.json`, such as `socket-uv-cdx.json`, so the `socket-cdx.json` name from Step 2 should match. The supported-files list above is the authority. Check the scan's file list to confirm. + +## Error Handling + +- **Feature not on the plan:** if the CLI or API says SBOM export, license reports, or another feature is not available on the user's plan, tell the user that plainly and point to . Do not guess which plan includes it. +- **401 or not signed in:** use `/socket-connect`. +- **403:** the token lacks the needed scope (`report:read` for export, `full-scans:list` for scan list and view, `full-scans:list` and `security-policy:read` for `scan report`, `license-policy:read` for the license policy) or is limited to other repos. The user creates a new token in the dashboard. +- **`Unknown argument(s)` from cdxgen:** the path is not written as `./name`, or the flag is not forwarded. See Step 2. +- **Empty or small SBOM:** the project type is wrong. Pass `-t` for each ecosystem. +- **Exit code 1 from `scan report`:** the scan failed policy. This is a result, not a crash. Show the alerts. + +## Tips + +- Use `-o` with a name that says the format, such as `sbom.cdx.json`, so readers know it is CycloneDX. +- Keep the default `pre-build` lifecycle. Only use `--lifecycle build` when the user accepts that project code will run. +- For SPDX, use the API export. Local generation is CycloneDX only. +- Commit SBOMs only if the user asks. They go stale with every dependency change. +- Delete or move a generated `socket-cdx.json` or `*.cdx.json` before `pnpm dlx socket scan create`, unless the user means it to be uploaded. A later scan uploads it as a pre-generated SBOM, and it goes stale. +- Delete a leftover `.socket.facts.json` before a scan without `--reach`. A later scan uploads it as an SBOM and carries stale reachability results. +- To fix license or security alerts, use `/socket-fix`, `/socket-dep-upgrade`, `/socket-dep-replace`, or `/socket-dep-patch`. To check one package's license first, use `/socket-inspect`. +- In CI, set `SOCKET_CLI_API_TOKEN` and run `pnpm dlx socket scan create --report`.

Not every Socket MCP server may expose the file tools. If they are missing, skip Step 4 and say so in the report. + +Never ask the user to paste a token into the chat, and never print one. + +## Step 1: Identify What Is Being Installed + +Work out what will actually run. Ask the user for the install command, the MCP config entry, or the repository URL. + +| Form | What it really is | Go to | +| ---------------------------------------- | ------------------------------------ | -------------- | +| MCP config with `npx -y ` | An npm package, installed at launch | Steps 2-4, 7 | +| MCP config with `uvx ` | A PyPI package, installed at launch | Steps 2-4, 7 | +| MCP config with a remote `url` | A server someone else runs | Step 6 (notes) | +| Skill installed from skills.sh | A git repository Socket has audited | Steps 5-6 | +| Skill or plugin from a git repository | Files plus any packages they install | Steps 6, 2-4 | +| Plugin manifest with a `.mcpb` or `.dxt` | A bundle downloaded and unpacked | Step 6 (notes) | + +For each package, record the ecosystem, the exact name, and the exact version. `npx -y` and `uvx` without a version pull the latest release on every launch, with no lockfile. A pinned top-level version still lets its dependencies float. + +## Step 2: Score Each Package With Socket + +**With the Socket MCP server:** call `depscore` with every package at once: + +```json +{ + "packages": [ + { + "ecosystem": "npm", + "depname": "@modelcontextprotocol/server-filesystem", + "version": "2.0.1" + }, + { "ecosystem": "pypi", "depname": "mcp-server-fetch", "version": "unknown" } + ] +} +``` + +`version: "unknown"` resolves to the latest version. `depscore` returns scores only (license, maintenance, quality, supplyChain, vulnerability) and a report link. It does not list alerts, and a missing score is not a safety verdict. A very low `supplyChain` score means you must get the alert list in Step 3 before going on. + +**With the Socket CLI:** get scores and the full alert list in one call. It accepts several packages: + +```shell +pnpm dlx socket package shallow npm @modelcontextprotocol/server-filesystem@2.0.1 --json +pnpm dlx socket package shallow pypi mcp-server-fetch --json +``` + +The CLI needs Socket account access. If it says you need an API token, ask the user to run `pnpm dlx socket login` in their own terminal (see `/socket-connect`). + +## Step 3: Check Alerts, Malware First + +From `pnpm dlx socket package shallow --json`, read `data[].alerts`. Each alert has `type`, `severity`, `category`, and `action`. + +**Stop if you see `malware` or `gptMalware`.** Report it first, using the block in Output Format, and do not install. + +**With only the Socket MCP server:** `depscore` lists no alerts, so check for malware with the threat feed. Call `organizations` to get your `org_slug`. Then call `threat_feed` with `org_slug`, `ecosystem`, `name`, and `version`, and leave `filter` at its default, `mal` (malware). Treat any hit as malware. The threat feed does not give the full alert list. For that, use the CLI command above. + +Then look for alerts that matter for an agent tool: `networkAccess`, `obfuscatedFile`, install scripts, shell access, and any alert with `action: "error"`. + +For what the package can do, get the deep score for one package: + +```shell +pnpm dlx socket package score npm @modelcontextprotocol/server-filesystem@2.0.1 --json +``` + +Read `data.self.capabilities` and `data.transitively.capabilities`. Values such as `net`, `shell`, `fs`, `env`, and `eval` tell you what the code can reach. Compare them with what the tool claims to do. A "read the weather" server that uses `shell` and `fs` needs a closer look. + +For more detail on any one package, use `/socket-inspect`. + +## Step 4: Read the Published Files + +Static review of the package as published finds things scores miss, such as tool poisoning in tool descriptions. + +1. Call `package_files` with `ecosystem`, `depname`, and an exact `version`. It returns a file tree. The token after each file size is that file's hash. For PyPI, pass `artifactId` (the wheel or sdist filename) when the version ships more than one file. +2. Call `package_file_grep` with a hash and a regex `pattern`. Set `caseInsensitive: true` for these patterns; matching is case-sensitive by default. Set `contextLines` (0-5) to see nearby lines. Useful patterns: + - `description:` - the text the agent will read for each tool + - `|ignore (all|previous)|do not tell|system prompt` - hidden instructions in tool text + - `child_process|execSync|spawn|subprocess|os\.system` - shell execution + - `fetch\(|https?://|XMLHttpRequest|requests\.` - network calls and hard-coded hosts + - `\.ssh|\.aws|\.npmrc|\.env|settings\.json|mcp\.json` - reads of credentials or agent config + - `bcc|webhook|eval\(|Buffer\.from\(.{0,40}base64` - exfiltration and obfuscation +3. Call `package_file_contents` with a hash to read a whole file. It refuses binary files. For a file over 1 MB it returns only the first 1 MB and says so; `package_file_grep` also searches only the first 1 MB. + +Also read the package manifest for install scripts (`preinstall`, `install`, `postinstall`). + +Static review cannot prove what tools a server lists at runtime. A server can change its tool list after you approve it. Say so in the report. + +## Step 5: Check the Socket Audit on skills.sh + +Socket audits skills listed on skills.sh, using static analysis and LLM review of the instructions, and rescans them when they change. The result is shown on skills.sh. It is not available through the Socket CLI, MCP tools, or API. + +Open this page for the skill: + +```text +https://skills.sh////security/socket +``` + +It shows **Pass** or **Fail**, the audit date, and four categories: malicious behavior, security concerns, code obfuscation, and suspicious patterns. Its audit metadata shows when it was analyzed and a Socket package URL that ends in a content hash. That hash is not a git commit. Compare the audit date with the date of the commit you will install. If the skill changed after the audit date, the audit does not cover your copy. + +Socket's AI Skills alert types are listed at . High severity ones include pre-execution shell commands, command injection, data exfiltration, hard-coded secrets, prompt injection, and tool chaining. + +If the skill is not on skills.sh, go to Step 6. + +## Step 6: Review a Skill or Plugin Checkout + +Clone the repository at a fixed commit. Do not install it yet. Read these files. They are where code and instructions enter the agent. + +**Skills (`SKILL.md` and its folder):** + +- Any `` !`command` `` that follows whitespace (including mid-line) and any ` ```! ` fenced block in `SKILL.md`. Claude Code runs these on the host when the skill loads. +- `allowed-tools` in the frontmatter. It pre-approves commands. +- `hooks` in the frontmatter. Claude Code registers these when the skill is invoked, and they keep running for the rest of the session. +- Scripts the skill tells the agent to run, and every URL they reach +- Text that tells the agent to hide actions, skip confirmation, read secrets, or ignore other instructions + +**Plugins:** + +- The manifest, `plugin.json` in the plugin's `.claude-plugin` folder (optional). Check `hooks`, `mcpServers`, `lspServers`, `experimental.monitors`, and `dependencies` (other plugins it pulls in). +- Hooks in the plugin's `hooks/hooks.json`. A `SessionStart` hook runs every time a session starts. +- MCP servers in `.mcp.json`, and LSP servers in `.lsp.json`.

They are put on the agent's `PATH`. +- `settings.json` and agent config files the plugin writes or edits + +For Claude Code plugins, also run the plugin's own check: + +```shell +claude plugin validate ./path-to-plugin --strict +``` + +**Remote MCP servers:** Socket cannot inspect a server someone else runs. Check who runs it, what it can reach, and what sign-in it asks for. Treat it as trusted code with your data. + +**Scan the checkout's dependencies.** First read any `socket.json` and `socket.yml` in the checkout and treat them as untrusted. The CLI reads them. A `socket.json` can turn on `--auto-manifest`, which runs build tools such as the repo's own `./gradlew`. A `socket.yml` can hide manifests from the scan. Then, from inside the checkout, pass the flags explicitly: + +```shell +pnpm dlx socket scan create . --no-auto-manifest --tmp --report +``` + +`--no-auto-manifest` stops the CLI from running build tools. `--tmp` keeps the scan from becoming a regular scan, or the alerts page, in your organization's dashboard. The CLI uploads the dependency manifests and lockfiles it finds, such as `package.json` and `requirements.txt`, subject to the repo's own `socket.yml` ignores. It does not analyze `SKILL.md`, hooks, shell scripts, or prompt text. See `/socket-scan` for reading the results. + +## Step 7: Install Pinned, Through Socket Firewall + +Install the vetted version, not "latest at launch". Socket Firewall (`sfw`) blocks known malware while the package manager downloads. See `/socket-firewall` to set it up. If the tool already ran through `npx` or `uvx`, its files may be in the package manager's cache, and `sfw` cannot block a cached copy. See `/socket-firewall` for clearing the cache first, and ask the user before running any cache-clearing command. + +For an npm MCP server, install it into its own folder with an exact version and no install scripts: + +```shell +mkdir -p ~/mcp && cd ~/mcp && npm init -y +sfw npm install --save-exact --ignore-scripts @modelcontextprotocol/server-filesystem@2.0.1 +``` + +Then point the agent's MCP config `command` at `~/mcp/node_modules/.bin/` instead of `npx -y`. This gives you a lockfile and a fixed version. + +For a PyPI server, install the exact version with `sfw pip install` or `sfw uv pip install` into a virtual environment, and point the config at it. Socket Firewall documents npm, yarn, pnpm, pip, uv, and cargo. It does not document `npx`, `uvx`, or `pnpm dlx`, so do not rely on it for those. + +For skills, pin both the installer and the skill. Install from a fixed commit, not a branch: + +```shell +npx skills@ add /@ --skill +``` + +Socket Firewall does not vet the `skills` installer when it runs through `npx`. To vet it, install it first with `sfw npm install`. + +Re-run this skill when you update to a new version or commit. + +## Output Format + +### If Malware Is Detected + +When malware is detected, the output **MUST** begin with this warning before any other content: + +> **MALWARE DETECTED - do NOT install this package.** +> +> **Package:** `{name}` ({ecosystem}) +> **Malware type:** {description of malware behavior} +> +> **Recommended action:** Remove this package immediately if already installed.

They do not prove the tool is safe." + +## Error Handling + +- **`depscore` returns "No packages were found":** check the name and ecosystem. Skills from skills.sh are not in `depscore`; use Step 5. +- **The CLI says it needs an API token:** the user runs `pnpm dlx socket login` in their own terminal. In CI, set `SOCKET_CLI_API_TOKEN`. See `/socket-connect` and `/socket-setup`. +- **The CLI or API says a feature is not on your plan:** tell the user plainly that their Socket plan does not include it, and point them to . Do not guess which plan includes it. +- **Ecosystem not supported:** `pnpm dlx socket package shallow` documents npm, pypi, nuget, gem, golang, and maven. For other ecosystems, say Socket could not score the package. +- **`package_files` needs a version:** pass an exact version, not a range. +- **`package_file_contents` refuses a file:** it is binary. Note it as not reviewed. +- **`package_file_contents` or `package_file_grep` says a file was truncated:** the file is over 1 MB. Note that only the first 1 MB was read or searched. + +## Tips + +- Malware first. Stop and report it before anything else. +- `npx -y` and `uvx` in an MCP config are an install step on every launch. Replace them with a pinned local install. +- Read tool descriptions. Hidden instructions there reach the agent even if the code looks clean. +- A skill or plugin can add hooks, MCP servers, and executables. Vet each one, not just the top-level files. +- An MCP Registry listing checks the name only, not what the server does. +- Socket's background reading: and . +- Use `/socket-inspect` for a deeper look at one package and `/socket-firewall` to block malware during installs. +- If you install a tool and later learn it was malicious, use `/socket-incident-response`. diff --git a/test/repo/unit/structural/paths-skill-discovery.test.mts b/test/repo/unit/structural/paths-skill-discovery.test.mts index 7dfabd2a..be9fc9b1 100644 --- a/test/repo/unit/structural/paths-skill-discovery.test.mts +++ b/test/repo/unit/structural/paths-skill-discovery.test.mts @@ -9,12 +9,20 @@ export const SKILLS_DIR = path.join(REPO_ROOT, 'skills') * Top-level skill directories expected under skills/ */ const EXPECTED_TOP_LEVEL = [ + 'knowledge-update', 'socket-connect', + 'socket-firewall', 'socket-fix', + 'socket-incident-response', 'socket-inspect', + 'socket-policy', + 'socket-pr-alerts', + 'socket-reachability', 'socket-release', + 'socket-sbom', 'socket-scan', 'socket-setup', + 'socket-vet-agent-tools', ] /**
