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 personamanagmentlayer/pcl at 79ccaa9820.

    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 enables AI agents to generate robust and maintainable TypeScript code for backend systems. It leverages deep expertise in TypeScript 5.0+ features, advanced type systems, and modern tooling best practices. The agent can assist with complex design patterns, optimize tsconfig.json configurations, and ensure maximum type safety through strict mode and advanced typing techniques.

When to use it

  • Generating backend code for new projects or features.
  • Refactoring existing JavaScript codebases into TypeScript.
  • Implementing complex data structures and algorithms with strong type guarantees.
  • Creating custom types and interfaces to enforce specific constraints.
  • Troubleshooting TypeScript-related errors and improving code quality.

Key capabilities

  • Expertise in TypeScript 5.0+ language features (Generics, conditional types, decorators).
  • Proficiency in advanced type systems including discriminated unions and branded types.
  • Knowledge of modern JavaScript syntax (Async/await, optional chaining).
  • Familiarity with popular package managers (npm, pnpm, yarn, bun) and build tools (Vite, webpack).
  • Ability to configure tsconfig.json for optimal type checking and compilation.

Example prompts

  • "Generate a TypeScript function that uses generics to process an array of numbers."
  • "Create a discriminated union type representing either a successful result or an error."
  • "Show me how to use branded types to prevent accidental mixing of User ID and Email strings."

Tips & gotchas

  • The skill relies on accurate prompts that clearly define the desired functionality.
  • It's designed for backend TypeScript development; it is not a general-purpose coding assistant.
  • To ensure type safety, always enable strict mode in your tsconfig.json file.
