SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill solves the common issue of teams advancing to the next implementation phase before confirming the current phase is fully complete, which leads to accumulated technical debt, missed deliverables, and unexpected quality issues in production.

Core Features & Use Cases

  • Parallel Scope & Quality Analysis: Runs simultaneous scope completion checks and full quality gate suites (linting, type checking, test coverage, security scans, smoke tests) to get a comprehensive view of phase status in one step.
  • Flexible Validation Modes: Supports full phase evaluation, mid-phase progress checks, and pre-implementation plan validation to fit different points in the development workflow.
  • Controlled Phase Transitions: Enforces explicit user approval before moving to the next phase, and integrates with git worktree and PR workflows to streamline handoffs.
  • Use Case: A development team building a customer portal in 6 phased increments can use this skill to confirm Phase 2 (user profile management) has all deliverables complete, all tests pass with 90%+ coverage, and no unplanned scope creep before starting work on Phase 3 (order history).

Quick Start

Use the phase-gate skill to check if Phase 4 of the e-commerce implementation is ready to move to the next phase.

FAQPage Schema
How do I validate phase completion before moving to the next software development phase?

To validate phase completion, run parallel scope completion checks and full quality gate suites including linting, type checking, test coverage, security scans, and smoke tests. This analysis enforces explicit approval before advancing, preventing incomplete work and scope creep from moving forward.

What is a phase-gate quality check and when do I need it in a phased implementation workflow?

A phase-gate quality check is a validation process that evaluates deliverable completion status and runs mandatory quality gates. You need it during phased software development workflows to support full phase validation, mid-phase progress tracking, and pre-implementation plan review.

Can I track mid-phase progress without completing a full phase transition?

Yes, you can track mid-phase progress without a full phase transition using flexible validation modes. This feature supports mid-phase progress checks alongside full phase evaluation and pre-implementation plan validation to fit different points in your development workflow.

Does the phase validation process integrate with git worktree and PR workflows?

Yes, the phase validation process integrates with git worktree and PR workflows to streamline handoffs. It enforces controlled phase transitions by requiring explicit user approval before moving to the next phase, ensuring traceable scope tracking and automated quality enforcement.

How do I prevent scope creep and incomplete deliverables from advancing in phased software development?

You can prevent scope creep and incomplete deliverables by running simultaneous scope completion checks and full quality gate suites. This controlled phase transition governance requires all deliverables to be complete and all tests to pass before advancing.
