What problem does it solve? Training data goes stale, APIs get deprecated, and best practices evolve, so framework code written from memory often contains outdated or incorrect patterns. This Skill grounds every implementation decision in official documentation, ensuring the code you receive is verifiable against authoritative sources. ## 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 specific official docs page for each feature, follows documented patterns, and avoids deprecated APIs. - Source Citation: Annotates framework-specific decisions with full URLs and quoted passages so you can verify every choice. - 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the useActionState reference from react.dev, implements the modern pattern, and cites the source instead of relying on outdated useState-based patterns. ## Quick Start Verify my framework code against the official documentation for the versions in my package.json and cite your sources for each pattern.
