Plan Validation Cycle Skill (Bridge)

Validates implementation plan readiness before entering DO phase.

Overview

This is a Validation Skill (bridge) that acts as a quality gate between plan-authoring-cycle and implementation-cycle.

Phases

Phase	Purpose
CHECK	Verify required sections exist
SPEC_ALIGN	Verify plan matches referenced specs
VALIDATE	Check section content quality
APPROVE	Confirm plan is ready

Note (Session 233): L4_ALIGN removed (was non-functional). SPEC_ALIGN provides requirements traceability via plan's References section.

Usage

Manual:

Skill(skill="plan-validation-cycle")

From implementation-cycle: Optional quality gate before DO phase.

Quality Checks

• Goal: Single sentence, measurable
• Effort: Real numbers from file analysis
• Tests: Concrete assertions
• Design: File paths and code snippets
• Steps: Actionable checklist items

Requirements Traceability

SPEC_ALIGN phase provides requirements traceability by:

1. Reading plan's ## References section
2. Reading each referenced specification
3. Comparing plan's Detailed Design against spec interface
4. Blocking on mismatch (prevents "assume over verify" anti-pattern)

L4 Requirements: Now in L4/ directory (Session 233 consolidation):

• L4/functional_requirements.md - Module function specs (for module work)
• L4/technical_requirements.md - How-to-enable patterns
