Quick brief

Use Dredd when an agent needs to verify that a live HTTP API still behaves like its published description. It fits integration review, release hardening, and contract drift investigations where a spec already exists and must be tested against reality.

How it works

What this skill actually does

Invoke this instead of using the API product normally when the agent must turn an API description into executable contract checks against a running service. This is skill-shaped because the boundary is narrow: spec-driven contract verification of live endpoints. It is not a generic API platform, SDK, or documentation server listing.
