What problem does it solve? Training data goes stale, APIs get deprecated, and best practices evolve, so framework code written from memory often contains outdated or incorrect patterns. This Skill grounds every framework-specific implementation decision in official documentation, so the code you receive is verifiable against authoritative sources. ## Core Features & Use Cases - Stack Detection: Reads dependency files like package.json, composer.json, requirements.txt, go.mod, Cargo.toml, or Gemfile to identify exact framework versions before writing any code. - Documentation-Grounded Implementation: Fetches the specific official documentation page for the feature being implemented, follows documented API signatures, avoids deprecated patterns, and treats fetched content as untrusted data rather than instructions. - Source Citation and Conflict Surfacing: Adds full-URL citations in code comments and conversation, quotes relevant passages for non-obvious decisions, and explicitly flags anything that could not be verified. - Use Case: When building a React 19 form, the Skill detects the version from package.json, fetches the useActionState reference from react.dev, implements the documented pattern, and cites the source instead of relying on a possibly outdated useState approach. ## Quick Start Implement this feature using source-driven development so every framework pattern is verified against the official docs and cited.
