SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents teams from advancing to the next development phase before the right artifacts and quality gates are in place, reducing late-stage rework and missed blockers.

Core Features & Use Cases

  • Phase-gated readiness validation: Produces a structured PASS/CONCERNS/FAIL verdict for Concept→Systems Design, Systems Design→Technical Setup, Technical Setup→Pre-Production, Pre-Production→Production, Production→Polish, and Polish→Release.
  • Artifact + quality checks: Verifies required files exist with meaningful content, runs cross-GDD / architecture consistency checks when applicable, and flags items that require manual confirmation.
  • Director Panel assessment: Optionally runs parallel director checks (creative/technical/producer/art) in lean/full review modes to catch readiness gaps beyond simple file presence.
  • Stage status update on success: When PASS and confirmed, updates production/stage.txt with the new stage name.

Quick Start

Run gate-check for Technical Setup → Pre-Production by executing: gate-check technical-setup.

FAQPage Schema
How do I validate phase gate readiness before advancing development?

Phase gate readiness validation checks required artifacts and quality criteria for the target gate, producing a structured PASS, CONCERNS, or FAIL verdict to confirm release readiness before advancing phases.

What is a phase gate readiness check and when do I need it?

A phase gate readiness check prevents teams from advancing to the next development phase before the right artifacts and quality gates are in place, reducing late-stage rework and missed blockers across project phases.

How do I check release readiness for a specific development stage transition?

Run a readiness check for a specific transition, like Technical Setup to Pre-Production, by executing the gate-check command with the target stage name to validate required files and architecture alignment.

Does phase gate validation support parallel director assessments for project readiness?

Yes, phase gate validation optionally runs parallel director assessments across creative, technical, producer, and art domains in lean or full review modes to catch readiness gaps beyond simple file presence.

Can I auto-detect the current development stage for phase gate validation?

Yes, the phase gate validation supports auto-detection of the current development stage with user confirmation, reading repository files and directories to validate artifact content before producing a readiness verdict.

What happens when artifact validation passes a phase gate check?

When artifact validation produces a PASS verdict and is confirmed by the user, the phase gate check automatically updates the production stage status file with the new stage name to reflect the phase advancement.
