What problem does it solve? When a bug report exists but the root cause is unknown, developers often guess or jump straight into fixing. This Skill enforces a disciplined analysis phase: actually reading the code, tracing the failure path, pinpointing the root cause at file:line level, and presenting 2-3 fix options for the user to choose before any code changes. ## Core Features & Use Cases - Code-Grounded Root Cause Analysis: Locates problem code via Grep/Glob, reconstructs the failure path, and classifies the root cause (logic error, state pollution, data format, concurrency, config, missing guard). - Impact Assessment: Evaluates blast radius, potentially affected modules, data integrity risks, and re-validates the severity rating from the original report. - Multiple Fix Proposals: Produces 2-3 fix options with pros, cons, and affected files, plus a recommended option, then waits for explicit user confirmation before any fix work begins. - Use Case: After a confirmed issue report ({slug}-report.md) exists, trigger this Skill to produce a structured {slug}-analysis.md with root cause and approved fix direction. ## Quick Start Ask the AI to analyze this bug and find the root cause based on the existing issue report, then present fix options for approval.
