To prevent requirement drift, specification-driven contracts validate code against YAML-defined forbidden and required regex patterns and run vitest contract suites to block PRs when rules are broken. This removes ambiguity between specs and implementation during development and CI.

Contract testing for MCP toolchains and multi-agent codebases validates agent prompts, tool schemas, and architecture constraints to ensure agents adhere to Zod schemas and maintain route coverage. It executes automated checks to block silent regressions across tool counts and agent behaviors.

Detect documentation drift and architecture gaps during CI by running automated contract verification workflows that check for module drift, agent coverage, and ADR gaps. The workflow reports violations across the repository and fails builds when documentation misaligns with code.

Yes, vitest executes generated contract suites that scan source code and tools to block merges on policy violations. The tests enforce non_negotiable rules and require explicit human overrides for any exceptions, ensuring strict governance over the codebase.

Contract YAML supports non_negotiable rules by defining strict forbidden and required regex patterns that block builds automatically. It includes a human override protocol that requires explicit approval to bypass these constraints when exceptions are necessary.

The best way to validate agent prompts and tool schemas against Zod schemas is applying specification-driven contracts that scan for forbidden patterns like direct math in prompts. This ensures multi-agent CFA projects maintain route and prompt coverage without silent regressions.
