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 AI-generated framework code often relies on stale training data, producing deprecated APIs and outdated patterns that break against current library versions.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 with full URLs. ## Core Features & Use Cases - Stack Detection: Reads dependency files like package.json, composer.json, or go.mod to identify exact framework versions before writing code. - Documentation-Grounded Implementation: Fetches the specific official docs page for each feature, follows documented API signatures, and avoids deprecated patterns. - Source Citation & Conflict Surfacing: Annotates code with full-URL citations, quotes relevant passages, 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fetches react.dev docs on useActionState, implements the documented pattern, and cites the source instead of using an outdated useState-based approach. ## Quick Start Ask the assistant to implement a framework feature using source-driven development so every pattern is verified against official docs and cited.
