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 5.1 | $0.00018 | $0.01826 |
| Opus 5 | $0.00009 | $0.00913 |
| Sonnet 5 | $0.00004 | $0.00365 |
| Haiku 4.5 | $0.00002 | $0.00183 |
Grade D, and why
init-marketplace scanned grade D with 3 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 12d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo apt install gh # ou yum, dnf selon la distro Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Init Marketplace
Initialise le marketplace et vérifie toutes les dépendances système nécessaires aux plugins.
Instructions à Exécuter
IMPORTANT : Exécute ce workflow étape par étape :
Étape 1 : Vérifier les dépendances système
Exécuter les vérifications suivantes en parallèle avec Bash :
# Vérifier chaque dépendance
which git && echo "✅ git installé" || echo "❌ git manquant"
which gh && echo "✅ gh installé" || echo "❌ gh manquant"
which node && echo "✅ node installé" || echo "❌ node manquant"
which npm && echo "✅ npm installé" || echo "❌ npm manquant"
which bun && echo "✅ bun installé" || echo "❌ bun manquant"
which pnpm && echo "✅ pnpm installé" || echo "❌ pnpm manquant (optionnel)"
which ccusage && echo "✅ ccusage installé" || echo "❌ ccusage manquant (optionnel)"
which biome && echo "✅ biome installé" || echo "❌ biome manquant (optionnel)"
Étape 2 : Afficher les versions
Pour chaque dépendance installée, afficher la version :
git --version
gh --version
node --version
npm --version
bun --version
pnpm --version 2>/dev/null || echo "pnpm non installé"
Étape 3 : Analyser les plugins installés
Lire .claude-plugin/marketplace.json pour obtenir la liste des plugins.
Pour chaque plugin, vérifier si ses dépendances sont satisfaites en se basant sur la section "Dépendances par plugin" ci-dessous.
Étape 4 : Générer le rapport
Créer un rapport structuré :
📦 Marketplace Claude Plugin - Rapport de dépendances
✅ Dépendances installées (X/Y)
- git v2.x.x
- gh v2.x.x
- node v20.x.x
- npm v10.x.x
- bun v1.3.8
❌ Dépendances manquantes (X/Y)
- biome (optionnel)
⚠️ Plugins affectés par les dépendances manquantes
- mlvn: Scripts de dev (biome manquant)
📊 Résumé par plugin
✅ git (1.10.2): Toutes les dépendances satisfaites
✅ github (1.3.1): Toutes les dépendances satisfaites
✅ mlvn (1.0.0): 100% fonctionnel (biome optionnel manquant)
...
Étape 5 : Proposer l'installation des dépendances manquantes
Si des dépendances critiques manquent, afficher les commandes d'installation :
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.

init-marketplace is a skill published in the GitHub repository atournayre/claude-marketplace (9 stars, last pushed 6mo ago), licensed MIT. It adds 18 tokens to every session and 1,826 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
