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.

Token cost

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.

Security

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.

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

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

    role="Analyste Financier Senior",
    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. "
        "Expert en lecture de bilans IFRS, vous détectez les signaux faibles que d'autres ignorent. "
        "Vous citez toujours vos sources avec l'URL et la date."
    ),

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.
