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 | $0.00530 |
| Opus 5 | $0.00009 | $0.00265 |
| Sonnet 5 | $0.00004 | $0.00106 |
| Haiku 4.5 | $0.00002 | $0.00053 |
Grade A, and why
framework:make:contracts 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 11d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Framework Make Contracts Skill
Instructions à Exécuter
IMPORTANT : Exécute ce workflow étape par étape :
Description
Génère l'ensemble des interfaces de contrats nécessaires pour une architecture respectant les principes Elegant Objects et DDD.
Ces interfaces servent de fondation pour toutes les autres skills du framework.
Usage
Use skill framework:make:contracts
Templates
OutInterface.php- Interface pour objets de sortie (DTO)InvalideInterface.php- Interface pour exceptions métierHasUrlsInterface.php- Interface pour objets ayant des URLsOutDataInterface.php- Interface pour data classes de sortieInvalideDataInterface.php- Interface pour data classes d'invalidationUrlsDataInterface.php- Interface pour data classes d'URLsStory/StoryInterface.php- Interface pour stories de testsDoctrine/DoctrineMigrationInterface.php- Interface pour migrations Doctrine
Variables requises
Aucune - Ces interfaces sont génériques et ne nécessitent pas de paramètres.
Dépendances
Aucune - C'est la première skill à exécuter (Niveau 0 - Fondation).
Outputs
src/Contracts/OutInterface.phpsrc/Contracts/InvalideInterface.phpsrc/Contracts/HasUrlsInterface.phpsrc/Contracts/OutDataInterface.phpsrc/Contracts/InvalideDataInterface.phpsrc/Contracts/UrlsDataInterface.phpsrc/Contracts/Story/StoryInterface.phpsrc/Contracts/Doctrine/DoctrineMigrationInterface.php
Workflow
- Vérifier si le répertoire
src/Contracts/existe - Créer la structure de répertoires si nécessaire :
src/Contracts/src/Contracts/Story/src/Contracts/Doctrine/
- Copier tous les templates d'interfaces depuis
framework/skills/make-contracts/templates/Contracts/verssrc/Contracts/ - Afficher la liste des fichiers créés
Notes
- Ces interfaces n'ont pas besoin d'être modifiées pour chaque projet
- Elles doivent être créées une seule fois par projet
- Toutes les autres skills du framework dépendent de ces interfaces
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

framework:make:contracts is a skill published in the GitHub repository atournayre/claude-marketplace (9 stars, last pushed 6mo ago), licensed MIT.
