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 | $0.00015 | $0.00584 |
| Opus 5 | $0.00008 | $0.00292 |
| Sonnet 5 | $0.00003 | $0.00117 |
| Haiku 4.5 | $0.00002 | $0.00058 |
Grade A, and why
dev:discover 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Configuration de sortie
IMPORTANT : Cette skill génère un résumé de compréhension structuré et nécessite un format de sortie spécifique.
Lis le frontmatter de cette skill. Si un champ output-style est présent, exécute immédiatement :
/output-style <valeur-du-champ>
Note : Une fois que le champ output-style sera supporté nativement par Claude Code, cette instruction pourra être supprimée.

Objectif
Instructions à Exécuter
IMPORTANT : Exécute ce workflow étape par étape :
Phase 0 du workflow de développement : comprendre le besoin utilisateur avant de coder.
Feature demandée
$ARGUMENTS
Instructions
1. Analyser la demande
- Si la demande est claire et complète, passer à l'étape 2
- Si la demande est ambiguë ou incomplète, poser des questions pour clarifier :
- Quel problème cette feature résout-elle ?
- Qui sont les utilisateurs cibles ?
- Quelles sont les contraintes connues ?
2. Explorer le contexte
- Chercher si des fichiers similaires existent déjà dans le projet
- Lire
CLAUDE.mdet.ai/pour comprendre les conventions - Identifier les patterns architecturaux utilisés
3. Résumer la compréhension
Présenter un résumé structuré :
📋 Résumé de la demande
**Feature :** {titre court}
**Problème résolu :**
{description du problème}
**Utilisateurs cibles :**
{qui utilisera cette feature}
**Contraintes identifiées :**
- {contrainte 1}
- {contrainte 2}
**Contexte technique :**
- {pattern existant pertinent}
- {fichiers existants liés}
4. Confirmer avec l'utilisateur
Demander confirmation avant de passer à la phase suivante :
✅ Est-ce que cette compréhension est correcte ?
Prochaine étape : /dev:explore pour analyser le codebase
Mise à jour du workflow state
Créer ou mettre à jour .claude/data/.dev-workflow-state.json (créer le répertoire si nécessaire)
Règles
- Ne PAS commencer à coder
- Ne PAS proposer d'architecture
- Se concentrer sur la COMPRÉHENSION du besoin
- Poser des questions si quelque chose n'est pas clair
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.

dev:discover is a skill published in the GitHub repository atournayre/claude-marketplace (9 stars, last pushed 6mo ago), licensed MIT. It adds 15 tokens to every session and 584 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 2026-08-31.
