Repomix

A tool that packs repository contents into a single AI-friendly file. Supports XML, Markdown, JSON, and plain text output formats.

Refer to README.md for full project overview and CONTRIBUTING.md for contribution procedures.

Repository Layout

• src/ — main source code (cli/, config/, core/, shared/). Feature-based structure; avoid dependencies between features
• tests/ — mirrors the src/ directory structure
• website/ — documentation website (VitePress); docs live in 15 language directories (en + 14 translated locales) under website/client/src/
• browser/ — browser extension

Coding Guidelines

• Follow the project's coding standards enforced by Biome (biome.json)
• Keep each file focused on a single responsibility. Treat ~250 lines as a signal to review a file's cohesion, not a mandate to split: split when the file mixes multiple responsibilities, but leave it as-is when the length comes from one cohesive concern (e.g. large data/config tables)
• Add comments in English where non-obvious logic exists
• Provide corresponding unit tests for new features
• Verify changes by running:
  bashCopy

  npm run lint  # Ensure code style compliance
  npm run test  # Verify all tests pass
  

Non-Obvious Rules and Pitfalls

• The config JSON schema under website/client/src/public/schemas/ is generated (npm run website-generate-schema; CI regenerates it after merges to main). Never edit it by hand.
• User-facing option or feature changes must update the docs in all 15 language directories under website/client/src/, not just en.
• Root npm run lint does not typecheck the website client. When changing website/client, verify with npm run docs:build in that directory.
• The VitePress build does not validate in-page anchor links; when renaming a heading, search the docs for links to its old anchor.
• GitHub Actions steps must be pinned to full commit SHAs with a version comment (e.g. uses: actions/checkout@<sha> # v7.0.0); pinact and zizmor enforce this in CI.

Commit Messages

Follow Conventional Commits with scope: type(scope): Description (e.g. feat(cli): Add new --no-progress flag)

• Scope: affected area (cli, core, website, security, etc.)
• Description: clear, concise present tense starting with a capital letter
• Commit body: follow the contextual-commit skill (.claude/skills/contextual-commit/SKILL.md)

Pull Request Guidelines

• Follow the template at .github/pull_request_template.md
• Include a clear summary of changes at the top
• Reference related issues using #issue-number
• Combine small, related changes in the same area into one PR rather than splitting them

Dependencies and Testing

Inject dependencies through a deps object parameter for testability:

export const functionName = async (
  param1: Type1,
  param2: Type2,
  deps = {
    defaultFunction1,
    defaultFunction2,
  }
) => {
  // Use deps.defaultFunction1() instead of direct call
};

• Mock dependencies by passing test doubles through the deps object
• Use vi.mock() only when dependency injection is not feasible

Output Generation

• Include all content without abbreviation, unless specified otherwise
• Optimize for handling large codebases while maintaining output quality
