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 mcart13/dev-skills at 87cfd2a8fa.

    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 guidance on optimizing TypeScript code for performance. It focuses on identifying and addressing common bottlenecks, suggesting best practices to improve runtime efficiency, and helping developers write more performant applications. The skill aims to help users understand how to profile their code and apply targeted optimizations.

When to use it

  • Performance regressions: When an application experiences slowdowns or performance degradation after a change.
  • Resource-intensive tasks: When dealing with computationally heavy operations like data processing, complex algorithms, or frequent DOM manipulations.
  • Code reviews: To ensure new code adheres to performance best practices and doesn't introduce bottlenecks.
  • Optimization efforts: When proactively seeking ways to improve the overall speed and responsiveness of a TypeScript project.

Key capabilities

  • Profiling guidance
  • Bottleneck identification
  • Performance optimization suggestions
  • Best practice recommendations for TypeScript code

Example prompts

  • "How can I profile my TypeScript application to identify performance bottlenecks?"
  • "What are some best practices for optimizing loops in TypeScript?"
  • "Suggest ways to improve the performance of this specific function: [code snippet]"

Tips & gotchas

The skill assumes a basic understanding of TypeScript and software development principles. While it offers suggestions, applying them effectively often requires careful consideration of the broader application context and potential trade-offs.
