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 sickn33/antigravity-awesome-skills at 5a4cdd9df8.

    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 orchestrates a comprehensive application performance optimization process across your entire system, from backend to frontend and infrastructure. It starts with profiling and baseline establishment, progresses through targeted optimizations at each layer, validates improvements via load testing, and establishes continuous monitoring. The goal is to address real bottlenecks using data-driven strategies and modern observability practices.

When to use it

  • Coordinating performance optimization efforts across backend, frontend, and infrastructure components.
  • Establishing initial baselines and profiling your application to pinpoint performance bottlenecks.
  • Designing load tests, setting performance budgets, or creating capacity plans.
  • Building observability systems focused on performance and reliability targets.

Key capabilities

  • Comprehensive Profiling: Uses a "performance-engineer" subagent for detailed performance analysis.
  • Phased Optimization: Executes optimizations in stages across the application stack.
  • Baseline Establishment: Creates initial benchmarks using profiling, tracing, and real-user data.
  • Load Testing & Validation: Validates improvements through load testing and sets safeguards against regressions.
  • Continuous Monitoring: Establishes ongoing monitoring for sustained performance.

Example prompts

  • "Profile application performance."
  • "Design a load test to assess the impact of recent changes."
  • "Establish baseline metrics for our frontend user experience."

Tips & gotchas

  • Ensure you have access to relevant metrics, tracing data, and profiling information.
  • Avoid performing load tests on production environments without proper approvals and safety measures in place.
  • Roll out performance changes gradually and always include rollback plans.
