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

**Orchestrator role:** Gather symptoms, spawn ecl-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 eCL subagent types (use exact names — do not fall back to 'general-purpose'):
- ecl-debug-session-manager — manages debug checkpoint/continuation loop in isolated context
- ecl-debugger — investigates bugs using scientific method
</available_agent_types>

<context>
User's input: $ARGUMENTS

Parse subcommands and flags from $ARGUMENTS BEFORE the active-session check:
- If $ARGUMENTS starts with "list": SUBCMD=list, no further args
- If $ARGUMENTS starts with "status ": SUBCMD=status, SLUG=remainder (trim whitespace)
- If $ARGUMENTS starts with "continue ": SUBCMD=continue, SLUG=remainder (trim whitespace)
- If $ARGUMENTS 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):
```bash
ls .planning/debug/*.md 2>/dev/null | grep -v resolved | head -5
```
</context>

<process>
Execute end-to-end.
