Does this skill write the actual application code?

No, it creates a comprehensive 'blueprint' or plan. This plan can then be executed by a developer or a Claude subagent using the execution skills.

Where are the generated plans stored?

Plans are automatically saved to a structured directory at docs/plans/{slug}/plan.md, allowing for easy version control and reference across different sessions.

What is the main benefit of using the writing-plans skill?

It ensures complex tasks are broken down into small, verifiable steps with built-in testing, significantly reducing errors and technical debt during implementation.

Why does the skill emphasize Test-Driven Development (TDD)?

Enforcing TDD in the planning phase ensures that every feature has a corresponding test and that the implementation strictly meets requirements before moving to the next step.

Productivity & Workflow

Generates granular, TDD-driven implementation plans for complex software tasks to ensure high-quality code and seamless execution.

This skill transforms high-level specifications into actionable, bite-sized implementation plans designed for both human engineers and AI subagents. By prioritizing Test-Driven Development (TDD), DRY principles, and frequent commits, it creates a roadmap that includes exact file paths, specific code snippets, and verification commands. It serves as a structural bridge between architectural planning and execution, offering multiple handoff strategies—such as subagent-driven or fresh session execution—to maintain technical context while minimizing conversation overhead and technical debt.

Key Features

01Automatic feature branch naming and standardized documentation paths
