SpecAgent (Contract-First)

Contract-first API design defines a clear specification for inputs, outputs, invariants, and failure modes before development begins, preventing scope creep and ensuring all stakeholders agree on exact request and response formats.

To generate a specification, define the component's exact request and response formats, error handling, performance guarantees, and acceptance criteria. This ensures a clear, unambiguous contract is established before any planning or development starts.

You need to define invariants and acceptance criteria when establishing a world model for your software components. This identifies necessary system constraints and ensures exact specifications are agreed upon before development to prevent misaligned expectations.

Yes, you can refine an existing specification to outline detailed failure modes and performance guarantees. This process ensures the contract clearly defines exact request and response formats alongside error handling for all stakeholders.

Yes, contract-first specification aligns with a provided world model and supports standard SDLC processes. It integrates directly into development workflows to enforce invariance and define exact component behaviors before building begins.

The best way to prevent scope creep is defining a clear, unambiguous contract before development begins. This specification outlines exact inputs, outputs, invariants, and acceptance criteria to ensure all stakeholders agree on the scope.
