AC n8n-create-nodes

Build production-ready n8n community nodes as npm packages, covering declarative and programmatic node styles. Use when user says "create an n8n node", "build an n8n integration", "scaffold n8n node package", "create n8n credential type", "create webhook trigger node", "create poll trigger", "publish n8n community node", or works with INodeType, n8n-workflow-SDK, n8n-nodes-starter, declarative routing, programmatic execute, or versioned nodes. Do NOT use for n8n workflow building or general workflow automation this skill is specifically for node package development.

How to improve

  1. The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec

  • warning body-long SKILL.md body ≈ 5069 tokens (recommended < 5000); move details to references/

Process rating: all ten parameters 58/100

  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Progress reporting. Says nothing while it works
  • 50When it triggers. No condition that starts the skill
  • 60Tools and files. Uses tools (web, node) that frontmatter does not declare
  • 70Execution cost. Instruction body is 5069 tokens
  • 100Steps. 44 steps
  • 100Failures and branches. 1 branches, has a failure section
  • 100Consistency. Name and required fields are in place
  • 100Running it twice. Mutating operations check current state
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
  • low 15 top-level sections: this looks like several domains in one skill
  • low The response is described with custom markup (9 tags): a typed call is more reliable

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

Quality signals

  • +3Output format is not stated: the model decides each time
  • +2Single-language instructions
  • +5Description quotes 7 example trigger phrases
  • +4Description says when NOT to use the skill
  • +3Description length 572: enough signal without eating the budget
  • +4Structure: 33 headings
  • +3Step-by-step instructions: 44 items
  • +4Has examples (13 code blocks)
  • +4Reference files are cited in the instructions (4 of 4)
  • +1License stated

Quality base 70; lint remarks subtract, signals add up to 100. Result: 88.

This is an instruction-only development skill for building n8n community nodes, with expected credential and webhook examples but one credential example that users should handle carefully.
