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.

SkillSpector: 1 finding, up to medium
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 →
- medium Data Exfiltration · line 68 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00081 | $0.02628 |
| Opus 5 | $0.00041 | $0.01314 |
| Sonnet 5 | $0.00016 | $0.00526 |
| Haiku 4.5 | $0.00008 | $0.00263 |
Grade A, and why
data-analyst-agent 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 10d 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 — 272 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Data Analyst Agent
Quand utiliser ce skill
Pour construire un agent capable d'analyser des données de manière autonome : connexion à une source (SQL, CSV, API), exploration du schéma, génération de requêtes en langage naturel, visualisations, rapport narratif avec insights actionnables.
Cas d'usage typiques : tableaux de bord conversationnels, assistants BI no-code, pipelines d'analyse automatisée, audit qualité de données.
Critères de choix d'architecture :
| Besoin | Architecture |
|---|---|
| Questions ponctuelles en temps réel | Event-driven (question → réponse) |
| Analyse récurrente planifiée | Pipeline batch avec scheduler |
| Dataset > 10 GB | Pousser le compute vers la DB (SQL-first) |
| Dataset < 500 MB | Pandas in-memory |
Workflow
1. Définir les modules de l'agent
Quatre modules obligatoires :
- NL Interface : LLM + prompt engineering (question → intent → code)
- Data Connectors : SQL, fichiers, APIs, cloud storage
- Code Kernel : exécution sécurisée pandas/SQL
- Reporting : visualisation + rapport narratif
2. Implémenter les connecteurs de données
# SQL — SQLAlchemy (PostgreSQL, MySQL, SQLite, BigQuery, MSSQL)
from sqlalchemy import create_engine, inspect, text
engine = create_engine("postgresql://user:pass@host/db")
inspector = inspect(engine)
# Générer le metadata store à la connexion
schema = {
table: {
"columns": inspector.get_columns(table),
"pk": inspector.get_pk_constraint(table),
"fk": inspector.get_foreign_keys(table),
}
for table in inspector.get_table_names()
}
# Read-only : toujours ouvrir en mode lecture
with engine.connect() as conn:
conn.execute(text("SET TRANSACTION READ ONLY"))
# Fichiers
import pandas as pd
df = pd.read_csv("data.csv", parse_dates=True, low_memory=False)
df = pd.read_excel("data.xlsx", sheet_name=0)
# API REST
import httpx
resp = httpx.get("https://api.example.com/data", headers={"Authorization": f"Bearer {token}"})
df = pd.DataFrame(resp.json()["data"])
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.

data-analyst-agent is a skill published in the GitHub repository khalilbenaz/claude-skills-collection (22 stars, last pushed 16d ago), licensed MIT. It adds 81 tokens to every session and 2,628 once invoked, about $0.0004 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.
