What problem does it solve? AI-generated framework code often relies on stale training data, producing deprecated APIs and outdated patterns that break against current library versions. This Skill forces every framework-specific decision to be verified against official documentation and cited, so the code you receive is traceable to an authoritative source. ## Core Features & Use Cases - Stack Detection: Reads dependency files (package.json, composer.json, requirements.txt, go.mod, Cargo.toml, Gemfile) to identify exact framework versions before writing any 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 primary sources. - Citation and Conflict Surfacing: Adds full-URL source citations in code comments and conversation, and explicitly surfaces conflicts between current docs and existing codebase patterns for the user to decide. - Use Case: You ask for a form handler in a React 19 project. 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 anchor so you can verify it. ## Quick Start Ask the agent to implement a framework-specific feature using source-driven development so every pattern is verified against the official docs for your detected versions.
