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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 41 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
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 | $0.00116 | $0.03506 |
| Opus 5 | $0.00058 | $0.01753 |
| Sonnet 5 | $0.00023 | $0.00701 |
| Haiku 4.5 | $0.00012 | $0.00351 |
Grade A, and why
crewai-expert 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 — 382 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CrewAI Expert — Systèmes Multi-Agents Collaboratifs
Critères de décision — Quand utiliser CrewAI
| Situation | Recommandation |
|---|---|
| Tâche décomposable en sous-rôles distincts (chercheur, rédacteur, réviseur…) | ✅ CrewAI |
| Pipeline séquentiel simple (A → B → C) avec LLM unique | ⚠️ LangChain chain suffisante |
| Parallélisme massif ou orchestration conditionnelle complexe | ⚠️ LangGraph ou Temporal |
| Workflow métier avec mémoire partagée entre sessions | ✅ CrewAI + memory |
| Prototype rapide < 1 jour | ✅ CrewAI (API haut niveau) |
| Budget API serré, chaque token compte | ⚠️ Surveiller usage_metrics, limiter max_iter |
Workflow en étapes
1. Installation et structure du projet
pip install crewai==0.100.0 crewai-tools==0.20.0
# Avec CLI officielle (recommandé pour nouveaux projets)
pip install crewai[tools]

2. Définition des agents
Chaque agent = role + goal + backstory (les trois piliers du comportement).
from crewai import Agent

goal="Extraire les indicateurs clés de {company} à partir de rapports publics",
backstory=(
"Vous êtes analyste financier avec 12 ans d'expérience chez un cabinet de conseil Tier-1. "

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.

crewai-expert is a skill published in the GitHub repository khalilbenaz/claude-skills-collection (22 stars, last pushed 19d ago), licensed MIT. It adds 116 tokens to every session and 3,506 once invoked, about $0.0006 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.
