- 02Isolated debugger subagent
- 03Diagnosis-only mode
- 04Debug session list, status, and continue commands
Use cases
- 01Investigating a reported software bug
- 02Getting a root-cause report without a fix
- 03Continuing an existing debug session

Subcommands: list · status <slug> · continue <slug>
<available_agent_types> Valid GSD subagent types (use exact names — do not fall back to 'general-purpose'):
