france-data-mcp: Skill for Claude Code

.claude/skills/ingestion-crons/SKILL.md

ingestion-crons is a skill for Claude Code from cturkieh/france-data-mcp. It costs 101 tokens per session (1,256 once invoked), scanned A, original, MIT.

A project-specific guide for scheduled data imports from FINESS, Ameli, and RPPS into a database. It documents the download, validation, replacement, monitoring, and known data-format traps.

In plain words
What is it for?
Use it before changing import scripts, database migrations, or related scheduled GitHub Actions jobs.
Why use it?
It helps prevent silent failures and incorrect records when external data sources change or contain unexpected values.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ingestion-crons scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Ingestion (crons GitHub Actions)

Déplacé verbatim depuis CLAUDE.md le 2026-09-06 (budget). Source de vérité pour ce périmètre ; CLAUDE.md ne garde que les règles de tête.

3 sources : FINESS (flux ANS JSON.gz quotidien, cron le 1er et le 15, ~105K), Ameli (hebdo, ~466K), RPPS (mensuel, ~2.28M). Pattern : download → SHA256 short-circuit si identique → COPY staging → validate → atomic swap → canary → ingest_log.

FINESS vient de l'ANS depuis 2026-09-05, plus du CSV DREES (flux arrêté le 2026-07-20 ; le cron a court-circuité en same_checksum/success quatre mois sans signal — d'où last_data_change_at/data_age_days dans data_freshness). Source de vérité : docs/plans/finess-migration-ans.md. Les trois pièges qui ont failli passer en silence, tous testés sur fixtures réelles (finess-ans-parse.test.ts) : (1) adresse géographique = usageAdresse "03", JAMAIS adresse[0] (2 294 EGE ont l'accueil devant) ; (2) deux paires de coordonnées dont le système WGS84/Lambert 93 s'inverse d'un enregistrement à l'autreresolveCoordinates détecte par plage de valeurs ; (3) seulement 74,9 % des EGE ont des coordonnées → repli previous_ingest (point de la prod par num_finess, tracé raw.geom_source), JAMAIS de centroïde commune dans finess.geom (le RPPS le recopierait en finess_join = tier précis). Parsing en flux obligatoire (715 Mo > limite de chaîne V8). Un débordement de colonne = null compté, jamais tronqué (un téléphone à deux numéros a fait échouer le premier dry-run ; parité DDL↔COLUMN_RULES testée). Les seuils qui décident du swap vivent dans finess-validate.ts (pur, testé sur les chiffres mesurés) — ne pas les réinliner dans main(). FINESS_DRY_RUN=1 = pipeline complet sans swap, staging conservée ; FORCE_REINGEST=1 bypass le checksum.

Service client typage : pour toute RPC ajoutée par migration récente, utiliser getUntypedServiceClient(source) (sinon tsc -p tsconfig.api.json échoue, types Supabase pas regénérés).

Canal d'apply des migrations en prod (V0.20+, débloqué) : MCP Supabase mcp__supabase_france_data__apply_migration({name, query}) — Claude apply directement depuis la session, sans intervention humaine, avec tracking propre dans supabase_migrations.schema_migrations. Workflow validé V0.20 : list_migrations (état) → execute_sql pg_proc (idempotence) → apply_migration({name: snake_case, query: SQL complet})execute_sql (tests fonctionnels : signature + appels réels + edge cases) → push code + tag. Le canal CLI supabase db push reste cassé (pattern CLI exige YYYYMMDDHHMMSS_ sans T, le repo a 52 migrations format T) — le MCP contourne en passant directement la chaîne SQL. L'auto-apply via GitHub Actions reste parqué (mémoire migration-autoapply-deferred partiellement obsolète — MCP en supersede pour les sessions Claude). Fallback dashboard SQL editor manuel (https://supabase.com/dashboard/project/_/sql/new) toujours valide si le MCP Supabase est down/non configuré. Le retry défensif PGRST204_RECOVERABLE_FIELDS protège la fenêtre transitoire push code ↔ apply migration (cf. ci-dessous).

Marqueur forced dans ingest_log (V0.12.2) : un run déclenché via FORCE_REINGEST=1 (workflow_dispatch) est marqué forced=true par shortCircuitIfSameChecksum(..., force=true) (chokepoint unique). Audit : SELECT * FROM ingest_log WHERE forced=true. Distingue un run ops manuel d'un cron normal — sinon perdu en audit quand checksums identiques.

Convention PGRST204_RECOVERABLE_FIELDS (V0.12.2) : writeIngestLog retry défensif si PGRST204 sur un champ optionnel récent (fenêtre transitoire push code ↔ apply migration). Tout nouvel ajout de champ optionnel dans IngestLogEntry DOIT être listé dans PGRST204_RECOVERABLE_FIELDS (scripts/ingest/shared.ts) jusqu'à propagation de la migration en prod, puis peut être retiré. Sans cet allow-list, un PGRST204 perdrait silencieusement TOUTE l'entrée ingest_log du run (classe close en V0.12.2). Best-effort doc : appliquer la migration AVANT de déployer le code.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ingestion-crons is a skill published in the GitHub repository cturkieh/france-data-mcp (3 stars, last pushed 4d ago), licensed MIT. It adds 101 tokens to every session and 1,256 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
