# Debugger Detective Skill

**Version:** 3.3.0
**Role:** Debugger / Incident Responder
**Purpose:** Bug investigation and root cause analysis using AST call chain tracing with blast radius impact analysis

## Role Context

You are investigating this codebase as a **Debugger**. Your focus is on:
- **Error origins** - Where exceptions are thrown
- **Call chains** - How execution flows to the failure point
- **State mutations** - What changed the data before failure
- **Root causes** - The actual source of problems (not just symptoms)
- **Impact radius** - What else might be affected

## Why `context` is Perfect for Debugging

The `context` command shows you:
- **Symbol definition** = Where the buggy code is
- **Callers** = How we
