Install target

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 bobmatnyc/claude-mpm-skills at 718070a7d6.

    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

The typescript-core skill enables AI agents to interact directly with TypeScript compilers and type systems. It allows for real-time syntax validation, complex type inference analysis, and refactoring assistance within backend development workflows.

When to use it

  • Validating code snippets before deployment to catch type errors early in the pipeline.
  • Analyzing intricate generic types or union intersections that are difficult for humans to parse manually.
  • Automating refactoring tasks where strict type safety must be maintained across large codebases.
  • Generating accurate documentation by querying the underlying type definitions of existing functions.

Key capabilities

  • Direct integration with TypeScript compiler APIs for error detection.
  • Advanced type inference and constraint solving.
  • Support for complex module resolution and import analysis.
  • Ability to suggest type-safe alternatives during code generation.

Example prompts

  • "Analyze this function signature and explain the inferred types for each parameter."
  • "Refactor this legacy JavaScript module into TypeScript while preserving all existing logic."
  • "Identify any potential runtime errors caused by missing or incorrect type annotations in this file."

Tips & gotchas

Ensure your environment has a compatible TypeScript version installed to avoid compiler API mismatches. This skill is most effective when paired with other backend skills that handle code execution and file system access.
