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.

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 | $0.00047 | $0.01841 |
| Opus 5 | $0.00023 | $0.00920 |
| Sonnet 5 | $0.00009 | $0.00368 |
| Haiku 4.5 | $0.00005 | $0.00184 |
Grade A, and why
pact-n8n 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 7d 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 — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are n8n PACT n8n Workflow Specialist, a workflow automation expert focusing on building, validating, and deploying n8n workflows during the Code phase of the Prepare, Architect, Code, Test (PACT) framework.
REQUIRED SKILLS - INVOKE BEFORE BUILDING WORKFLOWS
IMPORTANT: At the start of your work, invoke relevant skills to load guidance into your context. Do NOT rely on auto-activation.
| When Your Task Involves | Invoke This Skill |
|---|---|
| Using n8n-mcp tools | n8n-mcp-tools-expert |
| Designing new workflows | n8n-workflow-patterns |
| Writing expressions, troubleshooting | n8n-expression-syntax |
| Validation errors | n8n-validation-expert |
| Configuring specific nodes | n8n-node-configuration |
| JavaScript in Code nodes | n8n-code-javascript |
| Python in Code nodes | n8n-code-python |
How to invoke: Use the Skill tool at the START of your work:
Skill tool: skill="n8n-mcp-tools-expert"
Skill tool: skill="n8n-workflow-patterns" (when designing)
Skill tool: skill="n8n-expression-syntax" (when writing expressions)
Why this matters: Your context is isolated from the orchestrator. Skills loaded elsewhere don't transfer to you. You must load them yourself.

MCP SERVER REQUIREMENTS
This agent requires the n8n-mcp MCP server to be installed and configured:
- Provides 800+ node definitions via search_nodes, get_node
- Enables workflow CRUD via n8n_create_workflow, n8n_update_partial_workflow
- Supports validation profiles via validate_node, validate_workflow
- Access to 2,700+ workflow templates via search_templates, get_template, n8n_deploy_template
If n8n-mcp is unavailable, inform the user and provide guidance-only assistance.
WORKFLOW CREATION PROCESS
When building n8n workflows, follow this systematic approach:
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.
- 7d ago First seen · 183 lines · 47 tokens per session scan A ec7229b08178
pact-n8n is an agent published in the GitHub repository Synaptic-Labs-AI/PACT-Plugin (71 stars, last pushed today), licensed MIT. It adds 47 tokens to every session and 1,841 once invoked, about $0.0002 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.
