# Gate Check

> Validate readiness to advance between development phases. Produces a PASS/CONCERNS/FAIL verdict with specific blockers and required artifacts. Use when user says 'are we ready to move to X', 'can we advance to production', 'check if we can start the next phase', 'pass the gate'.

## About

# Gate Check

This is a full-fidelity Codex port of a large upstream studio workflow. Its
detailed phases, templates, checks, and handoff prompts live in
[`references/full-workflow.md`](references/full-workflow.md) to keep skill
discovery lightweight.

## Required procedure

1. Read `references/full-workflow.md` completely before executing this skill.
2. Follow its phases in order and preserve all approval, review, testing, and
   evidence gates.
3. Adapt shell syntax to the detected platform; use PowerShell on Windows and
   POSIX syntax on macOS/Linux.
4. Inherit the active Codex model and permission mode. Never weaken sandbox,
   approval, provenance, or human creative-control boundaries.
5. If a referenced project artifact is absent, report the gap and use the
   documented fallback instead of inventing completion evidence.
