An Agent That Hunts Bugs in My App While I Sleep

An Agent That Hunts Bugs in My App While I Sleep

Short summary

A developer built two AI agents that autonomously test a desktop app every hour via Playwright over CDP. The hunter agent explores the real signed-in app, classifies findings by confidence level, and files GitHub issues only for high-confidence reproducible bugs. A second agent reproduces, patches, and opens pull requests—catching subtle UX issues like stuck loading states and silent save failures that traditional tests miss.

  • •Two-agent system: a hunter explores the app hourly and files high-confidence bug reports as GitHub issues
  • •A fixer agent reproduces bugs, patches them, and opens PRs with before/after proof
  • •Key insight: getting an agent to find bugs is easy; getting it to be honest about findings is the real challenge

Generated with AI, which can make mistakes.
