Key features
  • Record every LLM call, tool call, and error with one decorator
  • Step-by-step replay of agent executions
  • Fork and cascade-replay from any failing step
  • Prove-the-fix verification before shipping
  • Runtime guardrails and circuit breakers
  • CI/CD regression gates
  • Multi-agent session tracking and topology graphs
  • Automatic hallucination and drift detection
  • Semantic search across agent runs
  • PII auto-redaction on every plan
  • 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
What makes it different
  • Turns production failures into regression tests that fail builds when behavior breaks
  • 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
