<arguments>$ARGUMENTS</arguments>

The text inside `<arguments>` is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.

<objective> Debug issues using scientific method with subagent isolation.

**Orchestrator role:** Gather symptoms, spawn gsd-debugger agent, handle checkpoints, spawn continuations.

**Flags:**

• `--diagnose` — Diagnose only. Returns a Root Cause Report without applying a fix.

**Subcommands:** `list` · `status <slug>` · `continue <slug>` </objective>

<available_agent_types> Valid GSD subagent types (use exact names — do not fall back to 'general-purpose'):

• gsd-debug-session-manager — manages debug checkpoint/continuation loop in isolated context
• gsd-debugger — investigates bugs using scientific method

</available_agent_types>

<context> User's input: the `<arguments>` block

Parse subcommands and flags from the `<arguments>` block BEFORE the active-session check:

• If the `<arguments>` block starts with "list": SUBCMD=list, no further args
• If the `<arguments>` block starts with "status ": SUBCMD=status, SLUG=remainder (trim whitespace)
• If the `<arguments>` block starts with "continue ": SUBCMD=continue, SLUG=remainder (trim whitespace)
• If the `<arguments>` block contains `--diagnose`: SUBCMD=debug, diagnose_only=true, strip `--diagnose` from description
• Otherwise: SUBCMD=debug, diagnose_only=false

Check for active sessions (used for non-list/status/continue flows):

ls .planning/debug/*.md 2>/dev/null | grep -v '/knowledge-base\.md$' | head -5

</context>

<process> Execute end-to-end. </process>
