What problem does it solve? Training data goes stale, APIs get deprecated, and best practices evolve, so code written from memory often contains outdated or incorrect framework patterns. This Skill grounds every framework-specific implementation decision in official documentation, so the code you receive is verifiable against authoritative sources. ## Core Features & Use Cases - Stack Detection: Reads dependency files like package.json, composer.json, requirements.txt, go.mod, or Cargo.toml to identify exact framework versions before writing any code. - Documentation-Grounded Implementation: Fetches the specific official docs page for the feature being implemented, 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: You are building a form in a React 19 project. The Skill detects React 19.1.0 from package.json, fetches the useActionState reference from react.dev, implements the documented pattern, and cites the source so you can verify every decision. ## Quick Start Implement the form submission logic for my project using source-driven development, checking my package.json and citing official documentation for every framework pattern you use.
