PROMPT="Exécute le workflow mails du spooler (agent gitea-issues-process). Les chemins des fichiers .pending sont dans projects/<id>/logs/gitea-issues/agent-loop.pending (ou exécuter ./gitea-issues/list-pending-spooler.sh). Pour chaque fichier .pending : lire le JSON (from, to, subject, body, message_id, base). Rédiger une réponse pertinente (uniquement ton texte ; pas de citation — mail-send-reply.sh refuse si le body contient From:, Message-ID, wrote:, etc.). Envoyer avec ./gitea-issues/mail-send-reply.sh --to <from> --subject \"Re: ...\" --body \"<ta_réponse>\" --in-reply-to \"<message_id>\". Après envoi réussi : ./gitea-issues/write-response-spooler.sh --base <base> --to <from> --subject \"Re: ...\" --body \"<ta_réponse>\" --in-reply-to \"<message_id>\".
