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 pproenca/dot-skills at cf93c57cac.

    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 a comprehensive guide to optimizing Expo React Native applications for performance. It offers 54 prioritized rules across nine categories, covering areas like launch time, bundle size, list virtualization, image optimization, and more. The goal is to assist in automated refactoring and code generation to improve mobile app performance.

When to use it

This skill is helpful when:

  • Writing new Expo React Native components.
  • Optimizing app startup and Time to Interactive.
  • Implementing lists, images, or animations.
  • Reducing bundle size and memory usage.
  • Reviewing code for mobile performance issues.

Key capabilities

  • Provides prioritized rules for optimizing Expo React Native apps.
  • Covers areas like launch time optimization, bundle size reduction, list virtualization, image optimization, data fetching patterns, navigation performance, re-render prevention, animation performance and memory management.
  • Includes specific recommendations such as using Hermes engine, avoiding barrel files, utilizing FlashList, and employing WebP format for images.

Example prompts

Here are some example prompts to guide the AI agent:

  • "What are the critical launch time optimization rules?"
  • "How can I reduce my app's bundle size?"
  • "Suggest best practices for optimizing lists in Expo React Native."

Tips & gotchas

  • The skill provides a prioritized list of recommendations, so focus on the highest priority items first (Launch Time Optimization and Bundle Size Optimization).
  • Some rules may require significant code changes or architectural adjustments.
