Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned proffesor-for-testing/agentic-qe at 124d8c735e.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides guidance and a checklist for effectively testing n8n workflows. It focuses on validating workflow structure, data flow between nodes, error handling, and execution performance. The skill emphasizes using realistic test data and verifying integrations with external services to ensure reliable automation. Ultimately, this helps users build robust and dependable automated processes within n8n.

When to use it

This skill is helpful in the following scenarios:

  • Testing new n8n workflows before deployment.
  • Validating changes made to existing workflows.
  • Debugging failed workflow executions.
  • Optimizing workflow performance.
  • Performing pre-deployment validation checks.

Key capabilities

  • Workflow Structure Validation: Checks for the presence of a trigger node and identifies any orphan nodes (nodes with no connections).
  • Data Flow Verification: Ensures data mappings between nodes are valid.
  • Error Handling Assessment: Validates that error workflows are defined and functioning correctly.
  • Credential Validation: Confirms that all referenced credentials exist.
  • Component Testing Focus: Provides guidance on testing triggers, action nodes, logic nodes, integration nodes, and error workflows individually.

Example prompts

Here are some example prompts an AI agent with this skill could respond to:

  • "How do I check for orphan nodes in my n8n workflow?"
  • "What should I verify when testing a new n8n workflow?"
  • "Can you give me a checklist for validating data transformations in my n8n workflow?"

Tips & gotchas

  • Test Data: Use realistic test data to accurately simulate real-world scenarios.
  • Execution Paths: Test each execution path within your workflow separately to ensure comprehensive coverage.
  • Credential Management: Ensure all credentials referenced by your workflow are valid and properly configured.
