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 marius-townhouse/effective-typescript-skills at d754db2077.

    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 allows AI agents to debug TypeScript code using source maps. It enables the agent to understand and interpret compiled JavaScript code by mapping it back to its original TypeScript source, facilitating error identification and correction. This is particularly useful when dealing with transpiled code where the visible JavaScript doesn't directly correspond to the TypeScript being written.

When to use it

  • Debugging complex build processes: When errors occur in production or during testing that are difficult to trace back to the original TypeScript source.
  • Understanding minified code: To decipher and debug heavily optimized (minified) JavaScript bundles.
  • Working with transpiled codebases: When developing applications using TypeScript, where the final deployed code is JavaScript generated from TypeScript.
  • Analyzing third-party libraries: When debugging issues in JavaScript projects that utilize TypeScript libraries.

Key capabilities

  • Source map interpretation
  • TypeScript error mapping to original source
  • Debugging transpiled JavaScript

Example prompts

  • "Explain the cause of this JavaScript error and show me the corresponding line in my TypeScript code."
  • "Can you help me debug this minified JavaScript file using its associated source map?"
  • "I'm seeing an error in production. Can you use the source maps to pinpoint the origin in my TypeScript project?"

Tips & gotchas

  • Ensure that source map files are generated during your build process and are accessible to the AI agent. Without them, this skill is ineffective.
