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 AI-generated code often relies on stale training data, producing deprecated APIs and outdated patterns that break against current framework versions.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 implementation 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, following a strict source hierarchy (official docs, official blogs, MDN, caniuse) and rejecting Stack Overflow or blog posts as authorities. - Source Citations: Annotates code comments and explanations with full URLs, deep-link anchors, and quoted passages so every decision can be verified. - Conflict Surfacing: When documentation contradicts existing project code, it presents both options instead of silently choosing one. - Use Case: You ask for a React 19 form handler. The Skill reads package.json, fetches react.dev/reference/react/useActionState, implements the modern Actions pattern instead of manual useState loading flags, and cites the exact doc section. ## Quick Start Use source-driven development to implement a form submission handler for this project, verifying the pattern against the official docs for my detected framework version and citing your sources.
