  • Evidence-gating architecture refuses answers instead of hallucinating
  • CI badge tracking faithfulness metrics is genuinely clever
  • MCP server integration fits current agent ecosystem
Weaknesses
  • AI verification layer space is getting crowded fast
  • No coverage tooling yet despite claiming production readiness
