Spec-driven platform to build, test, version and deploy AI agents from plain-English specs, exposed as typed REST APIs.
What it does
Logic is a spec-driven agent platform: you describe an agent's behavior, inputs and outputs in plain English and it ships a tested, versioned agent in about a minute. Each agent gets a built-in test harness, Git-like versioning with rollback, and can be exposed instantly as a strictly typed REST API with auto-generated docs, a shareable web UI and an MCP server.
