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

pm-brainstorm 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 1mo 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.

What it actually says

Pré-vol :

CORPUS_VAULT="${CORPUS_VAULT:-$CLAUDE_PLUGIN_OPTION_VAULT_PATH}"
if [ -z "$CORPUS_VAULT" ]; then
  echo "Vault non configuré. Définissez CORPUS_VAULT (dev local) ou configurez l'option utilisateur vaultPath dans le plugin installé (exposée sous CLAUDE_PLUGIN_OPTION_VAULT_PATH). Ni l'un ni l'autre n'est défini. Lancez /init-vault <chemin> pour initialiser un vault, puis exportez le chemin." >&2

Vérifiez que $CORPUS_VAULT/.corpus-vault existe. Si absent, refusez et indiquez au propriétaire de lancer /init-vault <chemin>. Voir corpus-core/rules/08-vault-structure.md.

Validation de l'argument :

$ARGUMENTS doit être fourni. Si absent, afficher :

Usage : /pm-brainstorm <idée produit>
Décrivez l'idée en texte libre. Exemple : /pm-brainstorm notifications push pour les utilisateurs mobiles inactifs

et s'arrêter.

Idée à tester : $ARGUMENTS

Invoquez la skill corpus-pm:brainstorm pour conduire la séance de pression-test. Le préfixe corpus-pm: est obligatoire : Claude Code namespace toujours les skills par plugin et ne résout pas les noms nus, même quand la commande et la skill sont dans le même plugin. Toutes les instructions d'analyse, la taxonomie des axes, les règles de citation et le comportement de signalement des lacunes se trouvent dans la skill.

Chemins : tous relatifs à $CORPUS_VAULT.

Quand terminé, rapportez :

  • Chemin du fichier brainstorm produit dans output/
  • Pages wiki citées (liste)
  • Lacunes signalées (dimensions sans données wiki)
  • Verdict de la séance (idée renforcée / affaiblie / incertaine)

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.
