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 Training data goes stale, APIs get deprecated, and best practices evolve, so code written from memory often contains outdated or incorrect framework patterns.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, giving you code you can verify and trust. ## Core Features & Use Cases - Stack Detection: Reads dependency files like package.json, composer.json, or go.mod to identify exact framework versions before writing any code. - Documentation-Grounded Implementation: Fetches the relevant official docs page, follows documented API signatures, and avoids deprecated patterns. - Source Citation: Adds full-URL citations in code comments and conversation, 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 the useActionState reference from react.dev, implements the modern pattern, and cites the source instead of relying on a possibly outdated useState approach. ## Quick Start Ask the agent to implement a framework-specific feature using source-driven development so every pattern is verified against the official docs and cited.
