What problem does it solve? AI-generated code often relies on stale training data, producing deprecated APIs and outdated patterns that break against current framework versions. This Skill grounds every framework-specific decision in official documentation so the code you receive is verifiable and current. ## 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 code. - Documentation-First Implementation: Fetches the specific official docs page for the feature being built, follows documented API signatures, and avoids deprecated patterns. - Source Citation: 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 react.dev docs for useActionState, implements the modern pattern instead of manual useState loading flags, and cites the source so you can verify it. ## Quick Start Ask the assistant to implement a framework-specific feature using source-driven development so every pattern is verified against the official documentation for your detected versions.
