Automated safety checks
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

About this skill
What it does
This skill allows AI agents to generate and execute JavaScript code within n8n workflows. It enables complex data transformations, API interactions, and custom logic directly inside your automation pipelines. The generated code is executed in a sandboxed environment for security and reliability.
When to use it
- Complex Data Manipulation: Transform data from multiple sources into a specific format required by another application.
- Custom API Interactions: Create unique API calls or handle complex authentication flows not supported by existing n8n nodes.
- Dynamic Workflow Logic: Implement conditional branching and dynamic behavior within your n8n workflows based on real-time data.
- Advanced Calculations: Perform intricate calculations or data aggregations that are beyond the capabilities of standard n8n operations.
Key capabilities
- JavaScript code generation
- Sandboxed JavaScript execution environment
- Integration with n8n workflows
- Supports a wide range of JavaScript libraries and APIs
Example prompts
- "Generate JavaScript to extract email addresses from this text: [text content]"
- "Write JavaScript code to format the date in ISO 8601."
- "Create a function that calculates the shipping cost based on weight and destination."
Tips & gotchas
- Requires a basic understanding of JavaScript programming.
- The sandboxed environment has limitations; access to external resources may be restricted.
