Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00020 | $0.00400 |
| Opus 5 | $0.00010 | $0.00200 |
| Sonnet 5 | $0.00004 | $0.00080 |
| Haiku 4.5 | $0.00002 | $0.00040 |
Grade A, and why
preflight 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 yesterday.
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.
What it actually says
Préflight Cortex $ARGUMENTS
Tu diagnostiques l'installation de Cortex pour un utilisateur qui vient de cloner le repo ou d'installer le plugin — il n'est ni expert PostgreSQL ni expert Python. S'il a passé un argument ($ARGUMENTS), c'est le symptôme qu'il observe : commence par le relier au check concerné.
Exécute python -m mcp_server.doctor (essaie python3 si python échoue)
et interprète la sortie :
- Pour CHAQUE check en échec : cite le nom exact du check, explique en une phrase ce qu'il vérifie, puis donne LA commande de réparation que le doctor propose — telle quelle, prête à copier.
- Ordonne les réparations par dépendance (Python → driver → DATABASE_URL → connexion → extensions → filesystem), pas dans l'ordre d'affichage.
- Si tous les checks passent : dis-le en une ligne et indique le premier
usage (
query_methodologyau prochain démarrage de session).
Format de sortie :
- Verdict : PRÊT / X réparations nécessaires
- Réparations dans l'ordre (numérotées, une commande par étape)
- Vérification finale : la commande à relancer pour confirmer
Ne modifie AUCUN fichier. Ne devine jamais une commande de réparation qui n'est pas dans la sortie du doctor : si le doctor ne propose rien, dis « le doctor ne propose pas de fix automatique pour ce check » et cite la section concernée de PRIVACY.md ou README.md.
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.

preflight is a command published in the GitHub repository cdeust/Cortex (71 stars, last pushed 3d ago), licensed MIT. It adds 20 tokens to every session and 400 once invoked, about $0.0001 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 2026-08-30.
