Does this skill help with team communication?

Yes, it includes stakeholder simulations that roleplay perspectives from Project Managers, DevOps, and Users to ensure the plan meets different organizational needs.

What is the primary goal of the 5d-refine skill?

Its primary goal is to stress-test a software development plan before implementation to catch high-level errors and architectural flaws that would be expensive to fix later.

When should I use this skill in my workflow?

Use it after your initial planning phase but before writing detailed specifications or code, especially when you want to validate a plan's robustness against unusual constraints.

What is an 'Inversion Attack' in this context?

It is a method where Claude argues against the proposed plan to expose hidden dependencies, false assumptions, and potential failure modes that the developer might have overlooked.

What are the exit criteria for the Refine phase?

You are ready to move to the SPEC phase once major objections are addressed, edge cases are documented, and high-risk dependencies have defined mitigation plans.

Productivity & Workflow

Stress-tests software development plans through adversarial review and edge-case analysis to prevent architectural errors before coding begins.

About

Part of the 5D Spec-Driven Development methodology, 5d-refine provides a structured framework for challenging and validating software plans before committing significant resources to implementation. It employs sophisticated techniques like inversion attacks, stakeholder simulation, and dependency audits to identify hidden risks, document edge cases, and ensure technical feasibility. By forcing a critical review phase between planning and specification, it helps developers build more resilient systems and avoid costly mid-implementation pivots caused by overlooked constraints.

Key Features

Systematic Edge Case Probing for all core system behaviors
1 GitHub stars
Comprehensive Dependency Audits to categorize and mitigate technical risks
