How does this skill improve software quality?

By forcing a structured review of assumptions, dependencies, and 'unknowns' before coding, it reduces technical debt and ensures the developer understands the problem space deeply before committing to changes.

What is the primary purpose of the 5D Gap Analysis skill?

The primary purpose is to identify everything that must change or be learned to implement a specification, preventing unexpected roadblocks during the coding phase.

What are the four quadrants of this analysis?

The analysis covers Code Gaps (technical changes), Knowledge Gaps (learning needs), System Gaps (infrastructure/tooling), and Alignment Gaps (communication/documentation).

When should I invoke the 5D Gap Analysis skill?

You should use it after a specification is written but before implementation begins, or whenever you need to assess the 'delta' between the current state and a desired outcome.

生产力与工作流

Identifies technical, knowledge, and system gaps between specifications and current codebases to prevent implementation surprises.

关于

The 5D Gap Analysis skill implements a comprehensive multi-quadrant assessment methodology to evaluate the distance between project requirements and their current state. By systematically examining code modifications, infrastructure needs, knowledge requirements, and stakeholder alignment, it helps developers build a structured roadmap before writing a single line of implementation code. This methodology is a core part of the 5D Spec-Driven Development (SDD) workflow, designed to surface hidden complexities, identify learning prerequisites, and ensure total project alignment early in the development lifecycle.
