prompt-contract

Prevent implementation drift by generating a structured prompt contract before coding begins. This contract defines explicit goals, constraints, output formats, and failure conditions, ensuring your refactoring or feature build remains aligned with the original specification.

A prompt contract is a four-part specification that defines concrete goals, hard constraints, output formats, and failure guardrails. It translates vague software engineering requests into measurable, approval-ready criteria before any implementation work starts.

Write buildable specifications by drafting a prompt contract that captures your script's success target, scope limits, and expected output format. This forces explicit, measurable requirements and lists specific edge cases that would make the automation incomplete.

You need a specification before starting a software build when handling non-trivial tasks like features, refactors, or scripts. Drafting a prompt contract ensures your requirements are explicit, measurable, and ready for user approval before execution begins.

Yes, this approach works for vague feature requests by translating them into a concrete success target. The prompt contract mechanism defines measurable outcomes and failure guardrails, capturing hard limits like compatibility and performance expectations before implementation.
