Scan the repo's schema/types/migrations (or, with no repo, ask the user for a short product description as the task explains) and resubmit with project_model populated.\n- Subsequent calls: send ONLY task + project_id. project_model is cached server-side from the first call; resending it wastes ~2–4k tokens per call and re-runs validation. Resend project_model ONLY when a response returns _meta.tda_status='setup_required' or 'model_stale'.\n\nUse project_id from .thedesignagent or memory across calls. Pass repo_hash (SHA256 of git remote origin URL) only as a fallback if no project_id is known yet.",
