 "title": "Scan a Kotlin change for known footguns before merge",
 "page_title": "How to scan a Kotlin change for known footguns before merge with Kotlin Footguns",
 "summary": "Run a 32-pattern scanner over the lines your branch adds and review each flagged trap.",
 "who": "A Kotlin developer about to open a pull request who wants a check against known Kotlin and Compose pitfalls.",
 "problem": "Common Kotlin, Compose and desktop JVM mistakes pass compilation and code review because they look correct on the surface.",
 "outcome": "A list of likely and look hits tied to specific trap files, each one confirmed or dismissed before the branch merges.",
 "steps": [
  "Install the skills into your project with `npx skills@latest add maxrave-dev/kotlin-footguns`, selecting the footgun-scan skill. (inferred, check the README)",
  "From the repository root, run `python3 .claude/skills/footgun-scan/scripts/scan.py --base origin/main --fail`.",
  "Read each likely hit and open the trap file it names to confirm or dismiss it.",
  "Read each look hit as a place to inspect, not a verdict.",
  "Fix the confirmed hits and run the scan again until it reports nothing you need to act on."
 ],
 "agent_prompt": "In the kotlin-footguns skills installed in <repo path>, run the footgun-scan script against origin/main and open the trap file for every likely hit. Expected output: each hit marked confirmed or dismissed with a one-line reason. Verify that every confirmed hit names a trap file that exists in the skill directory.",

 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The scanner only matches the 32 patterns it ships with, so a clean scan does not mean a change is free of the 228 traps.",

  "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"
