# Contribute A New API Surface ## Companion Guidance Use `karpathy-guidelines` alongside this skill for implementation or review work. Keep changes scoped, surface assumptions, and define focused validation before editing. Use this skill when contributing a public API addition or behavior change to the runtime or bindings. ## Default Guidance - Start from the shared core behavior first - Decide which bindings must expose the new surface - Follow the parity checklist in `add-binding-feature` - Update docs and examples in the same branch ## Minimum Acceptance - Public behavior is clearly described - Every affected binding is covered - The validation matrix matches the changed surfaces - PR notes explain the user-facing change ## References - `add-binding-feature` - `validate-change` - `CONTRIBUTING.md` - `review-doc-style`
