Double-check before you ship: grill the requirements, test the implementation, prove the delivery. An engineering-discipline bundle for DeepSeek Harness.
This repository also configures its own agents. See what dsh-doublecheck tells them →
Skill Claude CodeCodex
Delivery proof and the doublecheck report. Use when the work is done and the delivery must be proven — consolidate the spec, test timeline, review verdicts, and verification checks into a doublecheckreport, and only then claim completion.
Skill Claude CodeCodex
Adversarial self-review before delivery. Use once the implementation reaches green and before you declare the work done — assume the delivery fails its own spec, hunt for the strongest supportable objections, answer them, and re-review after fixes.

Requirements grilling for engineering tasks. Use before writing any code when the task's goal, boundaries, acceptance criteria, failure modes, priorities, or non-goals are not yet settled — interrogate the user across six dimensions, reach consensus, record a structured spec, and only then implement.
Skill Claude CodeCodex
Red/green test discipline for implementation work. Use once a doublecheck spec is on record and implementation is about to start — write a test that fails for the missing behavior, run it to see it fail (red), make the change, run again to see it pass (green).
