SpecLeft

SpecLeft is a spec-driven development framework designed to bridge the gap between feature intent and test coverage. It allows users to write human-readable feature specifications in Markdown, validate these specs, and automatically generate pytest test skeletons. The tool supports traceability of feature coverage as machine-verifiable contracts, making it particularly useful for integrating with AI agents. It emphasizes a local, secure workflow without BDD ceremony, framework lock-in, or any telemetry, ensuring that development remains efficient and focused on intent.
