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.

What it costs to keep this loaded
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 | $0.00091 | $0.02477 |
| Opus 5 | $0.00046 | $0.01239 |
| Sonnet 5 | $0.00018 | $0.00495 |
| Haiku 4.5 | $0.00009 | $0.00248 |
Grade A, and why
hierarchy-designer 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 — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Hierarchy Designer
1. Décider si une hiérarchie est justifiée
| Signal | Action |
|---|---|
| Tâche linéaire, < 5 agents, domaine homogène | Agent unique ou flat pipeline — pas de hiérarchie |
| 5–15 agents, 2–3 domaines distincts | Hiérarchie 2 niveaux (orchestrateur + workers) |
| > 15 agents, domaines hétérogènes, charge variable | Hiérarchie 3 niveaux avec managers intermédiaires |
| Sous-tâches complètement isolées | Préférer une orchestration par événements plutôt qu'une pyramide |
Coût réel d'une hiérarchie : +30–50 % de latence, débogage exponentiellement plus complexe, surface d'erreur plus large. N'ajouter un niveau que si le gain de parallélisme ou de spécialisation le justifie clairement.
2. Définir les niveaux et leur rôle
Orchestrateur (1 seul)
├── Manager A (domaine : recherche)
│ ├── Specialist Web
│ └── Specialist BDD
├── Manager B (domaine : rédaction)
│ ├── Worker Draft
│ └── Worker Révision
└── Manager C (domaine : validation)
└── Specialist Fact-checker
Règle absolue : maximum 4 niveaux. Au-delà, le gain de spécialisation ne compense plus le coût de coordination.
| Niveau | Rôle unique | Peut créer des agents ? | Portée des outils |
|---|---|---|---|
| Orchestrateur | Stratégie, décomposition, agrégation finale | Oui (managers) | Toutes ressources |
| Manager | Coordination d'un domaine, allocation de budget | Oui (workers dans son domaine) | Ressources du domaine |
| Specialist | Expertise profonde dans une niche | Non | Outils spécialisés seulement |
| Worker | Exécution atomique, sans décision complexe | Non | Scope minimal |
3. Formaliser les responsabilités (prompt système de chaque niveau)
Chaque agent reçoit un system prompt qui précise exactement :
- Son rôle et ses limites d'autorité
- Ce qu'il peut décider seul vs ce qu'il doit escalader
- Le format des messages entrants et sortants
- Son budget token/API calls
ORCHESTRATOR_PROMPT = """
Tu es l'orchestrateur. Tu reçois un objectif global.
1. Décompose en sous-objectifs par domaine.
2. Assigne chaque sous-objectif à un manager via un message JSON.
3. Attends les résultats, agrège, et produis la réponse finale.
Tu NE réalises pas de tâche atomique toi-même.
Budget max : {budget_tokens} tokens pour toute la session.
"""
MANAGER_PROMPT = """
Tu es le manager du domaine {domain}.
Tu reçois un sous-objectif. Décompose-le en tâches atomiques.
Assigne chaque tâche à un worker. Supervise et agrège les résultats.
Budget alloué : {child_budget} tokens. Escalade si insuffisant.
"""
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.

hierarchy-designer is a skill published in the GitHub repository khalilbenaz/claude-skills-collection (22 stars, last pushed 18d ago), licensed MIT. It adds 91 tokens to every session and 2,477 once invoked, about $0.0005 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.
