Selected work

All projects →
  • Sardis Working

    A policy engine that approves or denies an AI agent's payment against a signed mandate before any money moves, and proves every decision afterward.

    • agent trust
    • payments
  • OAPS / AICP Draft spec, working reference

    An open protocol that records who authorized an agent action, what limits applied, and what proof exists, shared across MCP, A2A, and payment systems.

    • protocol
    • standard
  • OSP Spec complete, SDKs working

    An open protocol that lets an agent discover, provision, and pay for a service in one HTTP call, then rotate the credentials it gets back.

    • protocol
    • infra
  • FIDES Core working, service partial

    A control layer that verifies an agent's identity, capabilities, and authority before an action runs, then logs tamper evident proof of the decision.

    • agent trust
    • identity
  • Agentbox v0.1 working

    Run an autonomous agent on your own machine with a phone approval gate for risky commands, instead of choosing between full trust and a separate box.

    • runtime
    • agents
  • Capsule Core working, adapters partial

    One TypeScript interface to run agent code across Docker, Cloud Run, Vercel, and Neon, where every adapter declares exactly what it supports.

    • runtime
    • sandbox
  • Switchboard Working

    A local daemon that gives parallel coding agents one shared, tamper evident ledger, so they stop redoing work and faking "done".

    • dev tools
    • agents
  • Vela Phase 0 working

    A control plane that scores and gates whether a code change, human or agent written, can be trusted before it merges.

    • agent trust
    • git
  • Yula Working core, hardening

    A control layer that classifies every agent tool call by how reversible it is, signs the authority behind it, then blocks it, holds it for approval, or runs it, with a timeline to verify, undo, or replay.

    • agent trust
    • control plane
