fix(hooks): check command hooks with TinySecurity and stop running project hooks - #8573
Behavior change: command hooks shipped in a project's .openhuman/hooks.json no longer run. User and workspace command hooks now pass the same TinySecurity command check as a scheduled shell job, so some existing user hooks will be disabled (details below). Prompt hooks are unaffected.
Summary
A command hook ran on the host with no security check at all. That includes hooks from a project's .openhuman/hooks.json, the layer a cloned repository controls. A repository could ship a hook that copies ~/.ssh/id_ed25519 out on the next shell call. This is TS-E2E finding TS-E2E-019.
Command hooks are now admitted when the hook config loads. Project-layer command hooks are dropped. Every other command hook must pass TinySecurity's command check, and a refused one is dropped. Each dropped hook is reported with a warning.
Problem
The hooks engine (tinyagents-hooks) spawns command hooks synchronously through hooks/shell.rs#command, with no policy call (main: exec.rs#spawn_local).
The project layer (<action_dir>/.openhuman/hooks.json) is controlled by whatever repository the agent works in. So opening a repository was enough to run its commands on the host, with the user's privileges.
Solution
hooks/host.rs#admit_command_hooks runs on every reload, before the warnings are published:
Project layer: every command hook is dropped, with "project hooks need isolation, which is not available yet".
It can't be isolated yet, for two reasons. The engine's spawner is synchronous, so there's no async jail to route through. And TinyBox's native jail currently fails on Linux (TS-E2E-020, still open).
Follow-up path: once the hooks engine supports an async spawner and the native jail runs on Linux, project hooks can run jailed instead of being dropped.
System, user and workspace layers: each command must pass cron::scheduler::shell_job::authorize_shell_command. That's TinySecurity's CommandFlow::Scheduled check, with the policy built from config.autonomy, the same check a cron shell job passes before it runs.
Config unreadable: every command hook is dropped, rather than any of them running unchecked.
Prompt hooks spawn no process and are kept unchanged.
What gets disabled (for release notes)
Project-layer command hooks: always disabled.
With [autonomy] enabled = false (the desktop/CLI config default): only hooks that reference a protected path, such as ~/.ssh, ~/.gnupg, ~/.aws or system roots.
With autonomy enabled (the embed runtime's default supervised access, and SaaS profiles), these are also disabled:
an unquoted >, >> or 2>&1;
tee or a single &;
$(…), backticks or ${…}, even inside quotes;
a leading NAME=value;
an executor (sh, bash, python…, node, env, …);
a base command not in allowed_commands. |, ; and && are checked segment by segment.
To re-admit a tool, add it to [autonomy] allowed_commands. Note that setting that key replaces the 40-entry default list. No entry admits a redirect; only level = "full" does.
Each disabled hook appears in hooks_reload's warnings and is logged as WARN [hooks] command hook <layer>:<name> disabled: <reason>.
Tests
New e2e target ts_e2e_hooks (tests/ts_e2e_hooks.rs, #[ignore], needs scripts/ci/ts-e2e-stage-modules.sh tinysecurity): project_command_hooks_do_not_run_and_user_hooks_pass_the_command_check.
A project hook that would copy a fake SSH key never runs.
A user hook echo ran still runs, which the test checks in hooks_test's runs.
A user hook that reads the key is disabled.
Red control: commit 8409c6dd00 (main plus the test only) fails with "a project hook ran on the host". On main all three hooks load and run.
Existing behavior:raw_coverage_all hooks_reload_list_and_test_round_trip_a_deny_rule passes on main and on this branch.
Submission Checklist
Tests added: an e2e test (above), with a red control on main.

Impact
Security: a repository can no longer run commands on the host through hooks. User and workspace hooks get the same command check as scheduled shell jobs.
Users: project command hooks stop running, and some user command hooks may be disabled (see "What gets disabled"). Each one is named in a warning.

Behavior Changes
Intended behavior change: project command hooks do not run; other command hooks must pass TinySecurity's command check.
User-visible effect: affected hooks are disabled with a warning in hooks_reload and the log.
Parity Contract
Legacy behavior preserved: prompt hooks, and command hooks the check admits, run as before.
Guard/fallback/dispatch parity checks: the same command check as cron shell jobs (authorize_shell_command).

Behavior Changes
Project-level command hooks no longer run. System-, user-, and workspace-level command hooks run only when permitted by security and privacy checks; hooks that are blocked, fail checks, or cannot be checked are disabled.
Non-command hooks, including prompt hooks, remain available.
Documentation
Updated hook guidance to explain command-hook restrictions and how to configure scripts when autonomy is enabled.
Hook reload filters command hooks before installation. Project-layer command hooks are excluded. Other command hooks must pass TinySecurity checks. The change also updates hook documentation, adds explicit failure handling to TinySecurity module staging, and adds an ignored end-to-end test.
Changes: Command Hook Admission and E2E Coverage
Layer / File(s)
Summary
Command hook admission and documentation crates/openhuman-core/src/hooks/host.rs, docs/gitbooks/en/developing/hooks.md
Hook reload excludes project-layer command hooks and checks other command hooks using the configured policy. Refusals and check errors disable command hooks. Documentation describes these rules and updates the example to use user-layer hooks.
Staging operations now call fail when they fail. Download retries and digest checks remain in place.
Hook admission E2E test crates/openhuman-cli/Cargo.toml, tests/ts_e2e_hooks.rs
Cargo registers the ignored test with the security-module feature. The test checks project-hook exclusion, allowed user-hook output, and refusal of a hook that attempts to copy a private-key sentinel.

Features
Added — Hook command admission at load time: Evaluates each command hook as a scheduled shell command at the Authorize stage, spends no action budget, turns a block, prompt or check error into a readable refusal reason, and applies the configured privacy mode so the local-only refusal reads the right mode before the live policy is installed. Admission is fail-closed: only an `Allow` gate admits. (crates/openhuman-core/src/hooks/host.rspub async fn reload(, crates/openhuman-core/src/hooks/host.rspub fn engine() -> &'static Arc<HookEngine> {)
Added — Project-layer command hooks never run: Command hooks from `<action_dir>/.openhuman/hooks.json` are dropped with a warning, closing the path where a cloned repository could run commands on the host with the user's privileges; prompt hooks from that layer still apply. (crates/openhuman-core/src/hooks/host.rsuse crate::core::runtime::DispatchCtx;)
Modified — Module staging script failure handling: Cache preparation, asset resolution, download, digest check, staging, extraction and unsupported-host detection now fail with an explicit reason via `fail` instead of relying on `set -e`, which is ignored inside the enclosing `if`; sourcing still leaves the caller's shell options alone and exports nothing on failure. (scripts/ci/ts-e2e-stage-modules.shts_e2e_stage() (, scripts/ci/ts-e2e-stage-modules.shNODE)
Modified — Hooks developer documentation on command-hook admission: Documents which layers' command hooks run, the warnings naming each disabled hook, the autonomy-dependent refusals, and moves the worked example to the user layer with a note on `allowed_commands`. (docs/gitbooks/en/developing/hooks.mdOpenHuman reads four locations and concatenates them.

Agent review details
critique
Conclusion: Success
Scope reviewed: all assigned evidence
Positive: Critique lane is answered with 5 of 5 files reviewed and reports no defect in the changed lines; it notes it could not verify the `tinyagents_hooks::command::config` types (`HookKind`, `HookLayer`, `HookConfig::by_event`, `label()`) because the vendor submodule is not checked out, and the code index is noted as behind this pull request.
Lane summary: The change adds a pre-install filter that drops project-layer and security-refused command hooks, running the check under the reload's own dispatch context. The filtering logic, the fail-closed config-read path, and the Prompt/Block handling all match the contracts of `check_command` and `CommandStage::Authorize` as read from the repository; I found no defect in the changed lines. I could not verify the `tinyagents_hooks::command::config` types (`HookKind`, `HookLayer`, `HookConfig::by_event`, `label()`) because the vendor submodule is not checked out, so the assumption that `definition.layer` is `Option<HookLayer>` and that `HookKind::Command` is the only process-spawning kind rests on the diff's own comment. _The code index is behind this pull request (indexed at `fdff7e4e538e`), so retrieved context may be out of date._
security
Conclusion: Success
Scope reviewed: all assigned evidence
Positive: Security lane is answered, reviewed 4 of 4 files with no findings: the filter sits on the reload path under the caller's context, only narrows what runs, and has no untrusted-input path to a dangerous sink. It flags one open question about whether `HookLayer::Project` is the layer assigned to the action-dir hooks.json, which lives in the not-checked-out vendor submodule.
Lane summary: The change adds a pre-load filter that drops project-layer command hooks and any command hook TinySecurity's command check refuses, failing closed when config cannot be read; refused hooks are surfaced as warnings. The filter sits on the reload path under the caller's context and only narrows what runs. I found no untrusted-input path reaching a dangerous sink and no repository-rule violation in this file; one open question is whether `HookLayer::Project` is the layer value assigned to the action-dir hooks.json, but that lives in the not-checked-out vendor submodule and the diff names its own rationale. _The code index is behind this pull request (indexed at `fdff7e4e538e`), so retrieved context may be out of date._
tests
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The change adds a load-time admission filter for command hooks, backed by an end-to-end test that pins the project-layer refusal, the user-layer admit path and the protected-path refusal, and rewrites the staging script to fail explicitly instead of relying on `set -e`. I found no defect I can anchor to a concrete reachable input: the hook filter has no unit test at the `admit_command_hooks` seam, but the e2e test does assert the three behaviours, and the shell changes are covered only by the e2e run which is by design. _The code index is behind this pull request (indexed at `fdff7e4e538e`), so retrieved context may be out of date._
commits

description
Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The description matches the diff: project-layer command hooks are dropped, other layers go through TinySecurity's command check, prompt hooks are kept, the docs describe the disabled cases, and the new e2e test plus its Cargo.toml entry land as described. The diff shown is the new cycle only, and I found nothing it does that the description leaves out. _The code index is behind this pull request (indexed at `fdff7e4e538e`), so retrieved context may be out of date._

With the staged TinySecurity release: a project-layer hook that copies a
private key, a user-layer echo, and a user-layer hook that names the key.
On main the project hook runs on the host and copies the key, and so does
the user hook that names it (TS-E2E-019).
…oject hooks
A command hook ran on the host with no TinySecurity check, including hooks
from a project's .openhuman/hooks.json, the layer a cloned repository
controls. A project could copy credentials out on the next shell call.
Hooks are now admitted when they load. Every project-layer command hook is
dropped with a warning: it cannot be isolated yet, because the engine spawns
hook processes synchronously and TinyBox's native jail does not run on
Linux (TS-E2E-020). Every other command hook passes the same command check
a scheduled shell job does, and a refused one is dropped with a warning.
A config that cannot be read drops every command hook. Prompt hooks spawn
nothing and are unchanged.
Fixes TS-E2E-019.
…load context
Admission asked TinySecurity at the Execute stage, so every reload spent one action of the hourly budget per hook. It now asks at Authorize, which filters what may load and spends nothing. Each later run is not charged: the engine spawns hook processes synchronously, which leaves no async seam for a per-run check (the same gap that keeps project hooks from being jailed).
The check now runs under the reload's own context (DispatchCtx::enter): TinySecurity's command check reloads config through the ambient context, which SaaS startup does not bind, so every non-project command hook was dropped there.
docs/gitbooks/en/developing/hooks.md now says project-layer command hooks do not run, what the command check refuses, and moves the example to the user layer.
…user hook ran
Hook admission built its policy with from_config, which leaves the privacy mode Standard. Hooks load before the live policy is installed, and with security off the local-only refusal of network commands reads only the policy's mode or the live one, so under [privacy] mode = "local_only" a hook such as curl was admitted. The admission policy now carries config.privacy.mode.
The staging script no longer relies on set -e, which bash ignores inside the if that runs it: every step (prepare, download, digest, copy, extract, resolve) checks its own result, so a failed download or a digest mismatch fails staging before tar sees the archive, and nothing is exported.
ts_e2e_hooks: a run is listed even when its process failed to spawn, so the allowed user hook now answers with a valid decision carrying a value only it prints, and the test requires that value and a null error.
Same script as tinyhumansai#8573 (CodeRabbit there): set -e is ignored inside the if that runs the staging function, so each step (prepare, resolve, download, digest, copy, extract) now checks its own result and a failure exports nothing. Byte-identical across the TS-E2E PRs.
check_hook_command refused only a Block gate. Under supervised autonomy with approval enabled an allowlisted command can come back Prompt, and a hook runs unattended, so admitting it ran the command without the approval it needs. Only Allow now admits the hook; Prompt is dropped with "needs approval, which a hook cannot ask for".

With security disabled, a user hook containing curl can be admitted under standard privacy. If the user then selects local-only privacy, the installed hook can still make network requests because the update does not reload it and later runs are not checked.

Summary
.openhuman/hooks.json, the layer a cloned repository controls. A repository could ship a hook that copies~/.ssh/id_ed25519out on the next shell call. This is TS-E2E finding TS-E2E-019.Problem
hooks/shell.rs#command, with no policy call (main:exec.rs#spawn_local).<action_dir>/.openhuman/hooks.json) is controlled by whatever repository the agent works in. So opening a repository was enough to run its commands on the host, with the user's privileges.Solution
hooks/host.rs#admit_command_hooksruns on every reload, before the warnings are published:cron::scheduler::shell_job::authorize_shell_command. That's TinySecurity'sCommandFlow::Scheduledcheck, with the policy built fromconfig.autonomy, the same check a cron shell job passes before it runs.What gets disabled (for release notes)
[autonomy] enabled = false(the desktop/CLI config default): only hooks that reference a protected path, such as~/.ssh,~/.gnupg,~/.awsor system roots.>,>>or2>&1;teeor a single&;$(…), backticks or${…}, even inside quotes;NAME=value;sh,bash,python…,node,env, …);allowed_commands.|,;and&&are checked segment by segment.[autonomy] allowed_commands. Note that setting that key replaces the 40-entry default list.
