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 wojons/skills at 5fe7152c66.

    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, wojons-performance-profiling, allows AI agents to analyze and identify performance bottlenecks in code. It provides insights into function execution times and resource consumption, enabling optimization efforts. The tool helps pinpoint slow or inefficient sections of a program for targeted improvement.

When to use it

  • Debugging Slow Applications: Use when an application is running slower than expected and you need to find the cause.
  • Optimizing Resource Usage: Employ this skill to identify areas where memory or CPU usage can be reduced.
  • Performance Tuning: Leverage for proactively improving performance before users report issues.
  • Analyzing Code Changes: Use after code modifications to ensure no regressions in performance have been introduced.

Key capabilities

  • Function execution time analysis
  • Resource consumption tracking (CPU, memory)
  • Bottleneck identification

Example prompts

  • "Profile the calculate_complex_data function and report any areas taking longer than 10ms."
  • "Analyze CPU usage during the data processing stage of this script."
  • "Show me a breakdown of memory allocation within the main loop."

Tips & gotchas

The skill requires access to the code being profiled. Ensure appropriate permissions and environment setup are in place before execution.
