Key features	Verify arbitrary diffs from agents, codemods, or humans Three-verdict system: SAFE, UNSAFE, UNPROVEN Runs test suite on isolated shadow tree copy Changed-line coverage attestation for Python Reproducible verification report with audit-grade record MCP server for AI agents to verify before landing CI gate that blocks unsafe merges Syntax and imports validation gates Runs locally with no code upload to external service	Session replay for MCP servers to identify failed agent sessions Clustering reports by agent goals and workflows Priority ranking weighted by frequency, failed workflows, and affected accounts Claude Code generates pull requests with tests Review queue with diff, tests, agent reports, and evidence Isolated git worktree prevents unauthorized code push Schema validation and rate limiting for feedback Open Agent Feedback Protocol with TypeScript and Python SDKs GitHub integration for draft PR creation
What makes it different	Only system that proves changed lines are actually tested, not just that tests pass Works with any AI coding agent and integrates via MCP Code never leaves your machine; runs entirely locally Free local CLI with unlimited verifications, paid only for managed infrastructure	Only AI agent failures on successful HTTP responses get detected and ranked Automated pull request drafts with your approval required before shipping Session replay captures failures even when agents don't report them Pay only for coding-agent runs, not feedback submission Open protocol and SDKs can be self-hosted at no cost
