How to audit desktop packaging, signing and CI config with Kotlin Footguns

Check a desktop JVM build for packaging, code-signing and CI traps before a release.

Who it is forA desktop JVM developer shipping a Compose or Kotlin app to Windows, macOS or Linux through CI.

The problemBuild flags, packaging steps and signing setup can behave differently per platform, and failures often appear only in release builds.

The outcomeA review of the build and CI files that names the desktop-and-build-footguns traps that apply and the fix each one describes.

What you need first

  • A Kotlin, Compose Multiplatform or desktop JVM project in a git repository
  • Claude Code, or any coding agent that reads the open agent-skills format
  • Python 3 for the footgun-scan script
  • Node.js with npx, if you use the skills CLI install

Steps

  1. Install the plugin in Claude Code with /plugin install kotlin-footguns@maxrave after adding the marketplace.
  2. Ask the agent to open the desktop-and-build-footguns index.
  3. Give the agent your build script and CI workflow files.
  4. Have the agent open each matching trap and check the build file against its verification steps.
  5. Run the verification commands each trap lists against your own tree and record the results.

Prompt for your agent

Using the desktop-and-build-footguns skill from kotlin-footguns, audit the build and CI files at <project path>. Expected output: a table of matched traps with file and line, and a verification result for each. Verify that every verification command you run is one the trap file lists, and that you did not invent any new command.

Caveat. The traps cover desktop packaging and signing patterns seen in one project, so they do not replace platform-specific release checks for your own signing setup.
