# Skill: Workflow - General Debugging

Workflow for general debugging tasks in a pristine branch or project work,
without the overhead of issue tracking. Use this skill when investigating
crashes, hangs, or unexpected behavior where no specific issue ID is provided.

## Principles

1. **Lightweight & Focused**: Focus on the immediate problem without the
   overhead of issue tracking conventions (e.g., `regress-<id>` naming, `Bug:`
   tags) unless requested.
2. **Efficient Investigation**: Prioritize quick root cause analysis using GDB
   and targeted code reading over exhaustive documentation.
3. **Pristine Branch Work**: Assume you are working on a clean branch or ongoing
   project work where changes are local.
4. **Architectural Skepticism**: Always question your fix. Ensure it addresses
   the root cause and not just a symptom.

## Workflow

### 1. Problem Triage

- Reproduce the issue if possible.
- Analyze the symptom (crash, hang, incorrect output).
- If a repro script is available, do not modify it directly. Create a scratch
  copy for investigation.

### 2. Static & Dynamic Analysis

- Use `code_search` or `grep_search` to locate relevant code based on stack
  traces or symptoms.
- Use GDB (`gdb-mcp`) to inspect runtime state, set breakpoints, and trace
  execution.
- Focus on understanding the immediate failure context before expanding the
  scope.

### 3. Propose Fix

- Develop a minimal fix targeting the root cause.
- Follow V8 Best Practices.
- **Architectural Skepticism**: Argue against your own proposal. Does it disable
  optimizations? Does it violate invariants?

### 4. Verify

- Verify the fix against the repro or by running relevant unit tests.
- Ensure no new failures are introduced in related areas.

### 5. Finalization

- Format the code using `git cl format`.
- Present the fix to the user/main agent.
- Do not create commits or upload CLs unless explicitly requested.
