Install target

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 marcelocanovas/expo-build-preflight at 31c961cec7.

    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, expo-build-preflight, provides checks and validations before building an Expo project. It helps identify potential issues early in the development process, such as missing dependencies or incorrect configurations. This proactive approach reduces build failures and improves overall developer experience by catching errors before deployment.

When to use it

  • Before a new release: Run preflight checks to ensure all necessary assets are present and configured correctly for distribution.
  • After significant code changes: Validate the project's structure and dependencies after making substantial modifications to the codebase.
  • When encountering build errors: Use preflight to diagnose common configuration problems that might be causing build failures.
  • During CI/CD pipelines: Integrate preflight checks into automated workflows to prevent problematic builds from progressing further.

Key capabilities

  • Dependency validation
  • Configuration verification
  • Asset checking
  • Early error detection

Example prompts

  • "Run expo-build-preflight on my project."
  • "Perform a preflight check before building for iOS."
  • "What potential issues does expo-build-preflight identify?"

Tips & gotchas

This skill requires an Expo project to be present. It’s best used within the root directory of your Expo project where package.json resides.
