reticlehq/reticle
Reticle is a runtime verification tool that checks whether AI-generated code actually works by driving the running app and reporting pass/fail with file:line fixes.

Reticle provides machine-native runtime perception for web and desktop applications, enabling AI coding agents to verify their own output. It drives the real running application, reads what actually happened, and returns pass/fail/couldn’t-tell results along with the specific file and line to fix. It integrates with Claude Code and exposes an MCP server, positioning itself as a proof layer for agent-generated code.
