n8n-workflows

A set of rules for building n8n workflows, which connect tasks and services into automated processes.

In plain words
What is it for?
Use it to write Python code snippets, prepare agent prompts, arrange workflow nodes, document flows, and test error paths and data changes.
Why use it?
It keeps workflow code, prompts, tests, and the final workflow file organized and separately testable.

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.

Made for: Cursor.

Per session 8 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 271 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

n8n-workflows 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 2d 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.

What it actually says

n8n Workflows

Code Snippets

When creating code snippet functions:

  • Use Python, not JavaScript
  • Create them as separate files in the workflow directory
  • This allows independent unit testing
  • Edit Python directly and test it separately

Example structure:

workflows/
  my-workflow/
    process_data.py
    test_process_data.py
    agent_prompts.md
    workflow.json

Agent Prompts

Put agent prompts in separate .md files for easy editing:

# Agent: Data Processor

## System Prompt

You are a data processing agent...

## User Prompt

Process the following data: {{ data }}

Workflow Assembly

Only at the end of a session, assemble the final .json workflow file by including:

  • Python snippets where appropriate
  • Agent prompts in the right nodes

Node Positioning

Pay attention to positioning nodes in the UI for good UX:

  • Group related nodes together
  • Use consistent spacing
  • Create logical left-to-right flow
  • Add sticky notes for documentation

Testing

Before assembling into JSON:

  • Unit test all Python functions
  • Validate all agent prompts
  • Test error handling paths
  • Verify data transformations
Changes

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-workflows is a cursor rule published in the GitHub repository TechNickAI/ai-coding-config (24 stars, last pushed 2mo ago), licensed MIT. It adds 8 tokens to every session and 271 once invoked, about $0.0000 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.
