Developer Tools / AI Agent Infrastructure

Stonefold

Stonefold is a deterministic enforcement gateway for AI agents. It sits between an agent and real systems, validates typed intents, applies policy, supports human approval and kill-switch controls, and records an audit trail for every attempt.

Why it was accepted

The page clearly presents a real AI-adjacent product with a defined job: deterministic enforcement for agent actions. It shows concrete capabilities, including typed intents, default-deny policy checks, human approvals, audit logging, kill switch behavior, and support for existing tools via a proxy. The crawl also provides strong evidence of a working prototype, open spec, and test kit, which makes it useful for a public listing.

Weakness

The crawl suggests the project is early-stage, but it does not show pricing, deployment options, supported platforms beyond a few examples, or how a team would integrate it end to end in production.
