What problem does it solve? Engineers often jump straight into code tracing when diagnosing bugs or planning fixes, missing the fact that the behavior may be documented, already fixed upstream, or solved by known community workarounds. This Skill enforces a research-before-planning protocol so investigations start from current external knowledge. ## Core Features & Use Cases - Documentation Verification: Searches official documentation first to confirm whether observed behavior is intended or already fixed. - State-of-the-Art Discovery: Finds community workarounds, recent discussions, and modern solution approaches for the problem type. - Parallel Investigation: Uses parallel sub-agents to search multiple sources simultaneously, then traces each problem end-to-end through source code until reaching at least 95% confidence in the root cause. - Use Case: When diagnosing a mysterious build failure, the Skill first checks the framework's current docs and issue trackers for known regressions before reading a single line of project code. ## Quick Start Apply the research-first protocol to investigate why the authentication token refresh intermittently fails before proposing any fix.
