What problem does it solve? When a bug is reported, developers often jump straight to patching symptoms without understanding the root cause, or they file vague issues that lack actionable fix plans. This Skill automates the investigation: it explores the codebase to find the root cause, then creates a GitHub issue containing a structured TDD-based fix plan. ## Core Features & Use Cases - Autonomous codebase investigation: Uses an Explore subagent to trace execution paths, inspect related tests, review recent git history, and identify the root cause rather than the symptom. - TDD fix planning: Produces an ordered list of RED-GREEN cycles where each test verifies behavior through public interfaces, keeping the plan resilient to future refactors. - GitHub issue creation: Files the issue directly via gh issue create using a structured template covering the problem, root cause analysis, TDD plan, and acceptance criteria. - Use Case: A user reports "the export button returns empty CSVs". The Skill traces the export flow, discovers the query filters out valid rows, and files an issue with a three-cycle RED-GREEN plan and acceptance criteria. ## Quick Start Ask the assistant to triage the bug you observed and file a GitHub issue with a TDD fix plan, providing a one-sentence description of the problem.
