What is an adversarial plan review?

It involves running a specialized 'plan-challenger' agent to identify edge cases, security risks, and logical gaps in your proposed implementation plan before any code is written.

When should I use the Planning skill instead of just coding?

Use it for new features or significant changes requiring more than three steps. It ensures architectural consistency and test coverage are established before implementation starts.

Does this skill handle bug fixes?

No, for bug fixes, it is recommended to use a dedicated debugging skill. The planning skill is optimized for new feature development and structured changes.

How does this skill integrate with testing?

It enforces a strict Test-Driven Development (TDD) approach, requiring skeleton modules and failing tests to be defined and verified before implementation code is written.

Productivity & Workflow

Architects, drafts, and reviews detailed TDD-based implementation plans for complex features and code changes.

This skill provides a structured framework for managing the entire lifecycle of a software feature, from initial requirement discovery to final merge. It guides Claude through a rigorous seven-phase process: exploring project context, brainstorming architectural approaches, drafting granular TDD-driven plans, undergoing adversarial and deep reviews, and managing execution handoffs. By enforcing small, testable steps and rigorous pre-coding reviews, it ensures high-quality code delivery while minimizing architectural debt and implementation errors.
