+# contentstack-cli-content-type – Agent guide
+
+**Universal entry point** for contributors and AI agents. Detailed conventions live in **`skills/*/SKILL.md`**.
+
+## What this repo is
+
+| Field | Detail |
+|-------|--------|
+| **Name:** | [contentstack/contentstack-cli-content-type](https://github.com/contentstack/contentstack-cli-content-type) (`contentstack-cli-content-type` on npm) |
+| **Purpose:** | Contentstack CLI (`csdx`) plugin that reads Content Type metadata from a stack: list, details, audit logs, same-stack or cross-stack JSON compare (HTML diff), and stack content-model diagrams. |
+| **Out of scope (if any):** | Bulk entry/asset mutations, Delivery API consumption, and unrelated HTTP clients—this package focuses on content-type introspection via the Management API patterns documented in the plugin skill. |
+
+## Tech stack (at a glance)
+
+| Area | Details |
+|------|---------|
+| Language | TypeScript, **`strict`** ([tsconfig.json](tsconfig.json)), target ES2017, CommonJS |
+| Build | `tsc -b`; output **`lib/`**; **`npm run prepack`** runs compile + `oclif manifest` + `oclif readme` |
+| Tests | Jest + ts-jest; tests under **`tests/`** ([jest.config.js](jest.config.js)) |
+| Lint / coverage | ESLint via **`npm run posttest`** ([.eslintrc](.eslintrc)); Jest coverage **`npm run test:coverage`**, global thresholds in [jest.config.js](jest.config.js) |
+| CLI / runtime | oclif; Node engines per [package.json](package.json); `bin` is `csdx` when installed as a CLI plugin |
+
+## Commands (quick reference)
+
+| Command type | Command |
+|--------------|---------|
+| Build (publishable) | `npm run prepack` |
+| Test | `npm test` |
+| Test + coverage | `npm run test:coverage` |
+| Lint | `npm run posttest` (or `eslint . --ext .ts --config .eslintrc`) |
+
+CI: [.github/workflows](.github/workflows) includes policy/SCA/release/issue automation—there is no single `ci.yml` that only runs `npm test`; follow team merge requirements.
+
+## Where the documentation lives: skills
+
+| Skill | Path | What it covers |
+|-------|------|----------------|
+| Dev workflow | [skills/dev-workflow/SKILL.md](skills/dev-workflow/SKILL.md) | Scripts, `tsconfig`, ESLint, Jest/coverage, oclif README/manifest, PR checks |
+| Content Type plugin | [skills/contentstack-cli-content-type/SKILL.md](skills/contentstack-cli-content-type/SKILL.md) | `ContentTypeCommand`, CMA vs SDK, auth, commands, compare/diagram |
+| Testing | [skills/testing/SKILL.md](skills/testing/SKILL.md) | Jest layout, mocks, conventions, coverage |
+| Code review | [skills/code-review/SKILL.md](skills/code-review/SKILL.md) | PR checklist, security and dependency review |
+
+An index with “when to use” hints is in [skills/README.md](skills/README.md).
+
+## Security
+
+See [SECURITY.md](SECURITY.md) for reporting issues.
+
+## Using Cursor (optional)
+
+If you use **Cursor**, [.cursor/rules/README.md](.cursor/rules/README.md) only points to **[AGENTS.md](AGENTS.md)**—same docs as everyone else.
