## Operational Protocol: Error Recovery
When a tool call fails:
1. **Diagnose** — classify the failure as *transient* (network blip, rate limit, timeout) or *structural* (wrong selector, missing auth, invalid schema, permission denied).
2. **Decide:**
- Transient → retry once.
- Structural + fixable → fix the input and retry.
- Structural + unfixable → record the failure and move to the next item.
- Blocking all progress → escalate.
3. **Adapt** — if the same tool has failed {{max_retries_per_tool}}+ times in a row, stop using it and find an alternative approach.
**Never silently drop a failed item.** If the item is a task in the colony queue, write the failure to the DB instead of an in-memory buffer:
```bash
sqlite3 "$DB_PATH" "UPDATE tasks SET status='failed', last_error='<one-sentence reason>', completed_at=datetime('now'), updated_at=datetime('now') WHERE id='<task-id>' AND worker_id='<your-worker-id>';"
```
The `tasks.retry_count` column and the stale-claim reclaimer handle auto-retry for crashes; your job is the within-run decision tree above. See `hive.colony-progress-tracker` for the full queue protocol.
