Formal Safety Agent

AI Agent That Doesn’t Just Code—It Proves It

When you're building agentic systems—especially ones that touch critical infrastructure, finances, or lives—"it kinda works" doesn’t cut it. You need guarantees, not guesses. That’s where our Formal Safety Agent comes in: an AI-native assistant that doesn't just suggest code, but constructs formal guarantees alongside it.

The End of the Mystery Box

Modern AI tools generate code, but rarely justify it. Safety Agent takes a different approach. By interleaving reasoning with proving, it embodies a new paradigm of intelligent tooling that integrates formal mathematical proofs at its core.

We’re standing on the shoulders of giants here:

  • In Lean-STaR Zhang et al., 2024, researchers demonstrate how LLMs can interleave natural language “thinking” with formal proof steps, dynamically switching between informal intuition and rigorous logic. Safety Agent takes inspiration from this hybrid reasoning loop—using informal thinking to drive toward formal guarantees.

  • Draft, Sketch, and Prove Yang et al., 2022 showed how informal sketches can guide formal theorem provers. Similarly, Safety Agent begins with your code’s intention—what it’s supposed to do—and incrementally refines it toward something a proof assistant can understand and verify.

  • miniCTX Welleck et al.,2024 introduces a long-context architecture optimized for theorem proving, enabling a more holistic view of complex logical flows. Formal Agents uses these techniques to maintain coherence across large codebases and proof states, ensuring that formal safety doesn't fall apart at scale.

What Can It Do?

  • Generate formally verified snippets for critical parts of your application

  • Flag ambiguous logic and suggest provable alternatives

  • Provide proof sketches that evolve into Lean-style formalizations

  • Serve as a co-agent, not just a copilot—always optimizing for safety, not just speed

Agentic Coding, Verified

We're not here to build faster code—we're here to build trustworthy code. Safety Agent is for developers building systems where bugs are not an option: robotics, smart contracts, autonomous agents, and safety-critical infrastructure.

Want to make sure your AI system doesn’t hallucinate logic? Start by hiring an agent that thinks in proofs.
