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 charon-fan/agent-playbook at be7a9d7d17.

    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 performance engineering capabilities, allowing you to analyze and optimize system performance. It can identify bottlenecks, suggest improvements based on best practices, and help ensure efficient resource utilization. The tool aims to improve application speed and responsiveness by addressing underlying performance issues.

When to use it

  • Slow Application: When users report slow loading times or sluggish response from an application.
  • Resource Constraints: When a system is nearing its capacity limits (CPU, memory, disk I/O).
  • Performance Regression: After code changes or infrastructure updates, when performance degrades unexpectedly.
  • Proactive Optimization: To identify and address potential performance issues before they impact users.

Key capabilities

  • Bottleneck identification
  • Performance improvement suggestions
  • Resource utilization analysis
  • Best practices recommendations

Example prompts

  • "Analyze the performance of my web application and identify any bottlenecks."
  • "Suggest ways to optimize database query performance."
  • "What are some best practices for reducing CPU usage in my server?"

Tips & gotchas

The skill's effectiveness depends on providing sufficient context about the system being analyzed. Ensure you have access to relevant logs and metrics for accurate assessment.
