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 | $0.00017 | $0.00666 |
| Opus 5 | $0.00009 | $0.00333 |
| Sonnet 5 | $0.00003 | $0.00133 |
| Haiku 4.5 | $0.00002 | $0.00067 |
Grade A, and why
dev:debug 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 9d 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Debug - Analyse et Résolution d'Erreurs
Instructions à Exécuter
IMPORTANT : Exécute ce workflow étape par étape :
Analyser une erreur (message ou stack trace) et proposer/appliquer résolution.
Variables
- ERROR_INPUT: $ARGUMENTS
- ERROR_TYPE: Type détecté (simple message vs stack trace)
- CONTEXT_FILES: Fichiers pertinents
- RESOLUTION_PLAN: Plan structuré si résolution demandée
Détection Automatique
Le système détecte automatiquement :
- Stack trace : Parsing + formatage + analyse approfondie
- Message simple : Analyse directe + diagnostic
Patterns stack trace :
Fatal error:,Uncaught,Exception,Error:- Présence de
at <file>:<line> - Multiple lignes avec indentation/numéros
Workflow
1. Identification Type
Si stack trace détectée :
- Parser trace (type, message, fichier:ligne, call stack)
- Formater hiérarchiquement
- Lire code source ligne incriminée
- Générer rapport
/tmp/stack-trace-analysis-[timestamp].md
Si message simple :
- Catégoriser (syntaxe, runtime, logique, config)
- Extraire infos contextuelles
2. Analyse Contexte
- Examiner fichiers mentionnés
- Analyser logs récents corrélés
- Vérifier environnement (deps, config)
- Identifier changements récents (git)
3. Diagnostic
- Cause racine vs symptômes
- Impact et criticité
- Solutions possibles + trade-offs
- Priorisation
4. Solutions
Stack trace : 3 niveaux
- Quick Fix ⚡ : Rapide, symptôme
- Recommandée ✅ : Équilibrée, cause
- Long-terme 🎯 : Robuste, prévention
Message simple : Plan résolution
- Étapes séquencées
- Tests validation
- Rollbacks prévus
- Risques estimés
5. Exécution (optionnel)
Si utilisateur demande résolution :
- Appliquer corrections pas à pas
- Valider chaque modif
- Vérifier résolution complète
- Documenter changements
Exemples
# Stack trace PHP
/dev:debug "Fatal error: Call to undefined method User::getName()"
# Fichier log
/dev:debug /var/log/app.log
# Message NPM
/dev:debug "npm ERR! missing script: build"
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.
- 9d ago First seen · 108 lines · 17 tokens per session scan A e893c5c6402d
dev:debug is a skill published in the GitHub repository atournayre/claude-marketplace (9 stars, last pushed 6mo ago), licensed MIT. It adds 17 tokens to every session and 666 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.
