LLM Response
**Monitoring du pool agencecom – Détection des anomalies**
- **Agents zombies (busy >1h sans complétion)** : analyse via `agent_task_runs` où `status = 'running'` et `started_at < now() - interval '1 hour'`.  
  Requête d’identification :  
  ```sql
  SELECT a.id, a.name, a.status, r.started_at
  FROM agencecom.agents a
  JOIN agencecom.agent_task_runs r ON a.id = r.agent_id
  WHERE r.status = 'running'
    AND r.started_at < NOW() - INTERVAL '1 hour';
  ```
- **Error count > 5 sur la dernière heure** :  
  ```sql
  SELECT id, name, error_count_last_hour
  FROM agencecom.agents
  WHERE error_count_last_hour > 5;
  ```
- **Drift de quarantaine** (agents encore quarantined alors que `quarantined_until > now()`) :  
  ```sql
  SELECT id, name, quarantined_until
  FROM agencecom.agents
  WHERE quarantined_until > NOW();

**Recommandations concrètes avec actions SQL (tables autorisées uniquement)**

- **Libération des agents zombies**  
  - Forcer la terminaison de leurs tâches fantômes :  
    ```sql
    UPDATE agencecom.agent_task_runs
    SET status = 'timeout',
        completed_at = NOW(),
        error_message = 'Zombie force-close by monitor'
    WHERE agent_id IN (
      SELECT a.id
      FROM agencecom.agents a
      JOIN agencecom.agent_task_runs r ON a.id = r.agent_id
      WHERE r.status = 'running'
        AND r.started_at < NOW() - INTERVAL '1 hour'
    )
    AND status = 'running';
    ```  
  - Remettre les agents à l’état `idle`, dissocier la session courante :  
    ```sql
    UPDATE agencecom.agents
    SET status = 'idle',
        current_session_id = NULL
    WHERE id IN (
      SELECT a.id
      FROM agencecom.agents a
      JOIN agencecom.agent_task_runs r ON a.id = r.agent_id
      WHERE r.status = 'running'
        AND r.started_at < NOW() - INTERVAL '1 hour'
    );
    ```

- **Mise en quarantaine automatique des agents à erreurs excessives**  
  - Isoler l’agent pour 30 minutes et réinitialiser son compteur d’erreurs horaire :  
    ```sql
    UPDATE agencecom.agents
    SET quarantined_until = NOW() + INTERVAL '30 minutes',
        status = 'quarantined',
        error_count_last_hour = 0
    WHERE error_count_last_hour > 5
      AND (quarantined_until IS NULL OR quarantined_until <= NOW());
    ```  
  - Cette action empêche la re-planification immédiate de tâches sur un agent instable.

- **Régulation du drift de quarantaine**  
  - Si un agent est en quarantaine sans tâche en échec prolongée ou sans dérive justifiée, lever la quarantaine :  
    ```sql
    UPDATE agencecom.agents
    SET quarantined_until = NULL,
        status = 'idle'
    WHERE quarantined_until > NOW()
      AND error_count_last_hour <= 5
      AND id NOT IN (
        SELECT DISTINCT agent_id
        FROM agencecom.agent_task_runs
        WHERE status = 'running'
           OR (status = 'failed' AND completed_at > NOW() - INTERVAL '10 minutes')
      );
    ```  
  - Pour les dérives restantes (probablement légitimes), prolonger de 15 minutes pour éviter les battements :  
    ```sql
    UPDATE agencecom.agents
    SET quarantined_until = GREATEST(quarantined_until, NOW() + INTERVAL '15 minutes')
    WHERE quarantined_until > NOW()
      AND id NOT IN (/* même exclusion que ci-dessus */);
    ```  
  - Ces commandes assurent que seuls les agents vraiment à risque restent en isolement.

Ces interventions ne touchent que `agencecom.agents` et `agencecom.agent_task_runs`, respectant strictement le périmètre autorisé.
