Recurse by Synnada

Recurse by Synnada is a serverless harness for building and running specialist AI agents. A developer states the task and how success will be judged, and a coding agent uses Recurse to generate, run and compare variants of an agent until one meets that bar.

What Recurse by Synnada does

• Agent variants: builds candidate agents from a system prompt and Python functions used as tools, then keeps the one that passes.
• Manifest contracts: pins each agent in a manifest with input and output schemas, and refuses manifests it does not recognise.
• Deployment: publishes the chosen agent as a tool, an MCP server or a bot.
• Schema-checked output: every successful run returns values that match the full output schema.
• Example agents: the site shows agents for game level design and RNA sequence design.

Who it serves

Teams with agents that need a fixed request and response, especially where a result can be checked automatically. The makers built it for their own client work, and their blog includes case studies from August 2026 on game level design.
