Is a partial pass possible in a gate review?

No, this skill enforces a strict binary decision rule. A gate is either a PASS or a FAIL based on criteria completeness; there is no provision for a partial pass in this framework.

How does this skill interact with the gate-reviewer agent?

This skill serves as a pre-flight preparation check. It ensures all documentation and evidence are ready before handing off the completed checklist to the gate-reviewer agent for formal execution.

How are waivers documented within the skill?

Waivers must include a specific justification, the name of the individual approver, and a risk acceptance statement. Undocumented or vague waivers are treated as a failure.

What are the 8 gates covered by this skill?

The skill covers all gates from A through H within the Waterfall Lifecycle framework, ensuring consistency across the entire project duration from initiation to closure.

What happens if a mandatory artefact is missing?

Any missing mandatory artefact results in an automatic gate FAIL. The skill prevents proceeding to assessment until the artefact is present or a formal waiver is documented.

Validates project readiness for waterfall gate reviews through structured binary checklists and evidence verification.

The Gate Checklist skill acts as a rigorous pre-flight validation tool for projects following the Waterfall Lifecycle framework. It enables Claude to systematically verify mandatory artefacts, assess evidence thresholds (exists, reviewed, approved), and document formal waivers across all eight lifecycle gates (A–H). By enforcing a binary pass/fail logic and ensuring all evidence is correctly indexed, this skill prevents premature gate reviews and ensures that the gate-reviewer agent has all necessary documentation for a successful formal execution.
