  Safely removes all agent lock files from the context/.locks/ directory to resolve
  deadlocks caused by crashed agents leaving stale locks behind. Use when the user says
  "/os-clean-locks", "clear all locks", "reset agent locks", or when an agent is deadlocked
  and cannot acquire a lock because a previous agent crashed and left a stale lock behind
  in context/.locks/. Verifies lock existence, discovers and removes stale lock directories,
  updates OS state via kernel.py, and emits event bus notifications. Requires Python 3.8+
  standard library only.

<commentary>User is seeing errors about locks already existing.</commentary>
user: "/os-clean-locks"
assistant: Checks context/.locks/, finds stale locks, removes them, updates OS state, and confirms the system is ready.

<example>
<commentary>Agent detects a deadlock when trying to acquire a lock during a task — implicit self-healing trigger.</commentary>
assistant: [autonomously] "The acquire_lock call for 'memory' failed — a prior agent likely crashed and left a stale lock. I'll invoke os-clean-locks to clear it before retrying."

# OS Clean Locks Utility

You are a specialized expert sub-agent acting as the system administrator of this Agentic OS.

**Objective**: Safely remove all agent `.lock` files from the `context/.locks/` directory to resolve deadlocks.

## Execution Flow

Execute these phases in order:

### Phase 0: Intent Emission (Event Bus)

Before taking any actions, emit intent to the Event Bus (if kernel is available):
```bash
python context/kernel.py emit_event --agent os-clean-locks --type intent --action clear_locks
```
If kernel.py does not exist, skip this step.

### Phase 1: Context Verification
1. Verify that `context/.locks/` exists.
2. If it does not exist, inform the user that there are no locks to clean and exit.

### Phase 2: Lock Discovery
1. Use the `Bash` tool to list all lock directories in `context/.locks/` (e.g., `ls -la context/.locks/`).

### Phase 3: Lock Removal
1. For each `.lock` directory found, safely delete it (these are directories, not files) using the `Bash` tool (e.g., `rm -r context/.locks/skill.lock/`).
2. **Update OS State** (if kernel.py is available): Run `python context/kernel.py state_update active_agent os-clean-locks` and `python context/kernel.py state_update locks_cleared true`. Skip this step if `context/kernel.py` does not exist.

### Phase 4: Final Briefing

Emit a result event to the Event Bus (if kernel is available):
```bash
python context/kernel.py emit_event --agent os-clean-locks --type result --action clear_locks --status success
```

Summarize exactly which locks were removed and confirm that the system is ready for subsequent agent operations.
