      "stdout": "# Agent Guide to pnpm Repository\n\nThis document provides context and instructions for AI agents working on the pnpm codebase.\n\n## Repository Structure\n\nThe pnpm codebase is a monorepo managed by pnpm itself. The root contains functional directories organized by domain:\n\n### Core Directories\n\n-   `pnpm/`: The CLI entry point and main package.\n-   `pkg-manager/`: Core package management logic (installation, linking, etc.).\n-   `resolving/`: Dependency resolution logic (resolvers for npm, tarballs, git, etc.).\n-   `fetching/`: Package fetching logic.\n-   `store/`: Store management logic (content-addressable storage).\n-   `lockfile/`: Lockfile handling, parsing, and utilities.\n\n### CLI & Configuration\n\n-   `cli/`: CLI command implementations and infrastructure.\n-   `config/`: Configuration management and parsing.\n-   `hooks/`: pnpm hooks (readPackage, etc.).\n-   `completion/`: Shell completion support.\n\n### Other Functional Directories\n\n-   `network/`: Network-related utilities (proxy, fetch, auth).\n-   `workspace/`: Workspace-related utilities.\n-   `exec/`: Execution-related commands (run, exec, dlx).\n-   `env/`: Node.js environment management.\n-   `cache/`: Cache-related commands and utilities.\n-   `patching/`: Package patching functionality.\n-   `reviewing/`: License and dependency review tools.\n-   `releasing/`: Release and publishing utilities.\n\n### Shared Utilities\n\n-   `packages/`: Shared utility packages (constants, error handling, logger, types, etc.).\n-   `fs/`: Filesystem utilities.\n-   `crypto/`: Cryptographic utilities.\n-   `text/`: Text processing utilities.\n\n## Setup & Build\n\nTo set up the environment and build the project:\n\n```bash\npnpm install\npnpm run compile\n```\n\n## Testing\n\nNever run all tests in the repository as it takes a lot of time.\n\nRun tests for a specific project instead:\n\n```bash\n# From the project directory\npnpm test\n\n# From the root, filtering by package name\npnpm --filter <package_name> test\n```\n\nOr better yet, run tests for a specific file:\n\n```bash\npnpm --filter <package_name> test <file_path>\n```\n\nOr a specific test case in a specific file:\n\n```bash\npnpm --filter <package_name> test <file_path> -t <test_name_pattern>\n```\n\n## Linting\n\nTo run all linting checks:\n\n```bash\npnpm run lint\n```\n\n## Contribution Workflow\n\n### Changesets\n\nIf your changes affect published packages, you MUST create a changeset file in the `.changeset` directory. The changeset file should describe the change and specify the packages that are affected with the pending version bump types: patch, minor, or major.\n\n**IMPORTANT: Always explicitly include `\"pnpm\"` in the changeset** with the appropriate version bump (patch, minor, or major). The pnpm CLI will only receive automatic patch bumps from its dependencies, so if your change warrants a minor or major version bump for the CLI, you must specify it explicitly. The changeset description will appear on the release notes page.\n\nExample:\n\n```\n---\n\"@pnpm/core\": minor\n\"pnpm\": minor\n---\n\nAdded a new setting `blockExoticSubdeps` that prevents the resolution of exotic protocols in transitive dependencies [#10352](https://github.com/pnpm/pnpm/issues/10352).\n```\n\n**Versioning Guidelines for pnpm CLI:**\n- **patch**: Bug fixes, internal refactors, and changes that don't require documentation updates\n- **minor**: New features, settings, or commands that should be documented (anything users should know about)\n- **major**: Breaking changes\n\n### Commit Messages\n\nFollow the [Conventional Commits](https://www.conventionalcommits.org/) specification.\n    -   `feat`: a new feature\n    -   `fix`: a bug fix\n    -   `docs`: documentation only changes\n    -   `style`: formatting, missing semi-colons, etc.\n    -   `refactor`: code change that neither fixes a bug nor adds a feature\n    -   `perf`: a code change that improves performance\n    -   `test`: adding missing tests\n    -   `chore`: changes to build process or auxiliary tools\n\n## Code Style\n\nThis repository uses [Standard Style](https://github.com/standard/standard) with a few modifications:\n-   **Trailing commas** are used.\n-   **Functions are preferred** over classes.\n-   **Functions are declared after they are used** (hoisting is relied upon).\n-   **Import Order**:\n    1.  Standard libraries (e.g., `fs`, `path`).\n    2.  External dependencies (sorted alphabetically).\n    3.  Relative imports.\n\nTo ensure your code adheres to the style guide, run:\n\n```bash\npnpm run lint\n```\n\n## Common Gotchas\n\n### Error Type Checking in Jest\n\nWhen checking if a caught error is an `Error` object, **do not use `instanceof Error`**. Jest runs tests in a VM context where `instanceof` checks can fail across realms.\n\nInstead, use `util.types.isNativeError()`:\n\n```typescript\nimport util from 'util'\n\ntry {\n  // ... some operation\n} catch (err: unknown) {\n  // ❌ Wrong - may fail in Jest\n  if (err instanceof Error && 'code' in err && err.code === 'ENOENT') {\n    return null\n  }\n  \n  // ✅ Correct - works across realms\n  if (util.types.isNativeError(err) && 'code' in err && err.code === 'ENOENT') {\n    return null\n  }\n  throw err\n}\n```\n\n## Key Configuration Files\n\n-   `pnpm-workspace.yaml`: Defines the workspace structure.\n-   `package.json` (root): Root scripts and devDependencies.\n-   `CONTRIBUTING.md`: Detailed contribution guidelines.\n"
