Grounds every implementation decision in official documentation. Use when you want to verify an approach against the official docs before implementing it, or when you want authoritative, source-cited code free from outdated patterns. Use when building with any framework or library where correctness matters.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Source-Driven Development ## Overview Every framework-specific code decision must be backed by official documentation. Don't implement from memory — verify, cite, and let the user see your sources. Training data goes stale, APIs get deprecated, best practices evolve. This skill ensures the user gets code they can trust because every pattern traces back to an authoritative source they can check. ## When to Use - The user wants code that follows current best practices for a given framework - Building boilerplate, starter code, or patterns that will be copied across a project - The user explicitly asks for documented, verified, or "correct" implementation - Implementing features where the framework's recommended approach matters (forms, routing, data fetching, state management, auth) - Reviewing or improving code that uses framework-specific patterns - Any time you are about to write framework-specific code from memory **When NOT to use:** - Correctness does not depend on a specific version (renaming variables, fixing typos, moving files) - Pure logic that works the same across all versions (loops, conditionals, data structures) …

How to install
mdr add addyosmani/agent-skills/source-driven-development@sha256:df38a852658679a6The line at the top of this page pins the label git:20261024.76cbb8a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
