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).

1. 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.

1. 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.
