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 ovachiever/droid-tings at 7acd12a754.

    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 syntax assistance for constructing expressions within n8n workflows. It helps users write valid and functional expressions, which are crucial for data manipulation, conditional logic, and automation tasks inside of n8n. The skill aims to reduce errors and improve the efficiency of workflow creation by providing helpful guidance on expression formatting and functionality.

When to use it

  • Building complex workflows: When you need to perform calculations or transformations on data within an n8n workflow.
  • Conditional logic: To create branches in your workflow based on specific conditions evaluated through expressions.
  • Data manipulation: For tasks like formatting dates, extracting values from strings, or converting data types.
  • Debugging existing workflows: When troubleshooting errors related to incorrect expression syntax.

Key capabilities

  • Expression Syntax Assistance
  • Workflow Integration
  • Error Reduction
  • Data Manipulation Guidance

Example prompts

  • "Generate an n8n expression to format a date string in YYYY-MM-DD format."
  • "How do I write an n8n expression to extract the email address from a text field?"
  • "What's the correct syntax for an n8n expression that checks if a number is greater than 100?"

Tips & gotchas

  • Requires familiarity with n8n workflows and their purpose.
  • The skill provides syntax guidance, but understanding the underlying logic of expressions is still essential.
