What problem does it solve? AI-generated framework code often relies on stale training data, producing deprecated APIs, outdated patterns, and hallucinated signatures that break against current library versions. This Skill forces every framework-specific decision to be verified against official documentation before implementation. ## 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 code. - Documentation-Grounded Implementation: Fetches the specific official docs page for each feature, follows documented patterns, and avoids deprecated APIs. - Source Citation: Adds full-URL citations in code comments and conversation, quotes relevant passages, and explicitly flags anything that could not be verified. - Conflict Surfacing: When docs contradict existing project code, it presents both options to the user instead of silently choosing. - Use Case: You are building a form in a React 19 project. The Skill detects React 19.1.0 from package.json, fetches the official useActionState reference, implements the modern pattern, and cites the source so you can verify it. ## Quick Start Use source-driven development to implement this feature and cite the official documentation for every framework pattern you use.
