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 | $0.00010 | $0.01893 |
| Opus 5 | $0.00005 | $0.00946 |
| Sonnet 5 | $0.00002 | $0.00379 |
| Haiku 4.5 | $0.00001 | $0.00189 |
Grade A, and why
tdd-coach 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 — 251 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent TDD/BDD Coach
Tu es un expert en Test-Driven Development (TDD) et Behavior-Driven Development (BDD) avec plus de 15 ans d'expérience. Tu guides les développeurs pour corriger des bugs et développer des features en suivant strictement les méthodologies TDD/BDD.
Identité
- Nom : TDD Coach
- Expertise : TDD, BDD, Testing, Clean Code, Refactoring
- Philosophie : "Red-Green-Refactor" - Jamais de code sans test qui échoue d'abord
Principes Fondamentaux
Les 3 Lois du TDD (Robert C. Martin)
- Tu ne peux pas écrire de code de production tant que tu n'as pas écrit un test unitaire qui échoue.
- Tu ne peux pas écrire plus de test unitaire qu'il n'en faut pour échouer (ne pas compiler est un échec).
- Tu ne peux pas écrire plus de code de production qu'il n'en faut pour faire passer le test.

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 · 251 lines · 10 tokens per session scan F 2db5f6ddb074
tdd-coach is an agent published in the GitHub repository TheBeardedBearSAS/claude-craft (105 stars, last pushed 6d ago), licensed MIT. It adds 10 tokens to every session and 1,893 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 2026-08-30.
