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: 2 findings, 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 MCP Rug Pull · line 16 npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.Fix: Pin the version: npx @scope/[email protected]
- medium Data Exfiltration · line 86 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 | $0.00093 | $0.02083 |
| Opus 5 | $0.00046 | $0.01042 |
| Sonnet 5 | $0.00019 | $0.00417 |
| Haiku 4.5 | $0.00009 | $0.00208 |
Grade A, and why
n8n-workflow-designer scanned grade A with 1 finding 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.

n8n Workflow Designer
Workflow en étapes
1. Choisir et déployer le mode d'exécution
Critères de décision :
| Contexte | Mode recommandé |
|---|---|
| Prototype / dev local | npx n8n ou Docker simple |
| Prod mono-serveur | Docker + PostgreSQL + reverse proxy |
| Prod haute dispo | n8n Queue Mode (Redis + workers) |
| Zéro ops | n8n Cloud |
Docker Compose minimal pour la prod :
services:
n8n:
image: n8nio/n8n:latest
environment:
- N8N_ENCRYPTION_KEY=<clé-aléatoire-32-chars>
- DB_TYPE=postgresdb
- DB_POSTGRESDB_HOST=postgres
- DB_POSTGRESDB_DATABASE=n8n
- DB_POSTGRESDB_USER=n8n
- DB_POSTGRESDB_PASSWORD=<mot-de-passe>
- WEBHOOK_URL=https://n8n.mondomaine.com/
- N8N_BASIC_AUTH_ACTIVE=true
- N8N_BASIC_AUTH_USER=admin
- N8N_BASIC_AUTH_PASSWORD=<mot-de-passe>
- EXECUTIONS_DATA_PRUNE=true
- EXECUTIONS_DATA_MAX_AGE=168 # 7 jours
volumes:
- n8n_data:/home/node/.n8n
ports:
- "5678:5678"
postgres:
image: postgres:16-alpine
environment:
POSTGRES_DB: n8n
POSTGRES_USER: n8n
POSTGRES_PASSWORD: <mot-de-passe>
volumes:
- postgres_data:/var/lib/postgresql/data
volumes:
n8n_data:
postgres_data:
Ne jamais exposer le port 5678 directement sur Internet — passer par Nginx/Caddy avec TLS.
2. Concevoir l'architecture du workflow
Avant de cliquer dans l'éditeur, répondre à ces questions :
- Trigger : Webhook (push), Cron (pull périodique), ou événement applicatif (ex. n8n trigger interne) ?
- Volume : traitement unitaire ou batch ? Si > 100 items → prévoir
Split In Batches. - Idempotence : que se passe-t-il si le workflow tourne deux fois avec les mêmes données ? Ajouter une vérification de doublon si nécessaire.
- Branchements : IF (2 branches), Switch (n branches), Merge (rejoindre des branches parallèles).
Squelette type :
[Trigger] → [Valider/Filtrer] → [Transformer] → [Action principale]

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.

n8n-workflow-designer is a skill published in the GitHub repository khalilbenaz/claude-skills-collection (22 stars, last pushed 19d ago), licensed MIT. It adds 93 tokens to every session and 2,083 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
