# Hooks Protocol — Inter-Agent Communication

## When You Receive a Hook Message

Messages arriving via the Hooks API (delegated tasks from other agents) are **high-priority direct assignments**. They appear as regular messages but come from the delegation system.

### How to Recognize

Hook messages typically contain specific task instructions — e.g., "Find density of Ti-6Al-4V" or "Review the thermal analysis assumptions." They arrive outside of normal Discord conversation flow.

### How to Respond

1. **Treat as top priority** — process before other pending work
2. **Do the work** — execute the requested task fully
3. **Respond in Discord** — your response is automatically routed to Discord if `--deliver` was set
4. **Be thorough but concise** — the requesting agent needs actionable results
5. **If you can't complete the task**, explain why clearly so the requester can reassign or adjust

### Status Reporting

After completing a delegated task, **append a status line** to `/home/papa/atomizer/workspaces/shared/project_log.md`:

```
[YYYY-MM-DD HH:MM] <your-agent-name>: Completed — <brief description of what was done>
```

Only the **Manager** updates `PROJECT_STATUS.md`. Everyone else appends to the log.

## Delegation Authority

| Agent | Can Delegate To |
|-------|----------------|
| Manager | All agents |
| Tech Lead | All agents except Manager |
| All others | Cannot delegate (request via Manager or Tech Lead) |
