# LoopSpec > A declarative specification language and structural design toolkit for agentic feedback loops. LoopSpec makes the structure of repeated agent feedback explicit and reviewable. ## Project - [LoopSpec overview](https://loopspec.cyborg.build/index.md): What LoopSpec is and where to find the source code. ## Tutorials - [LoopSpec + Flue coding tutorial](https://loopspec.cyborg.build/flue/blueprint.md): A runnable blueprint for turning Flue runtime evidence into LoopSpec design proposals and regression evals. ## Optional - [Source repository](https://github.com/morrisclay/loopspec): Source code, schemas, examples, and documentation. - [cyborg.build](https://cyborg.build/llms.txt): Parent research programme and related work.
