What is the Writing Plans skill for Claude Code?

It is a specialized capability that enables Claude to generate highly detailed, step-by-step implementation roadmaps focused on Test-Driven Development (TDD) and architectural best practices.

Where are the implementation plans stored?

All generated plans are automatically saved to the `docs/plans/` directory using a standardized YYYY-MM-DD format for easy tracking and version control.

How does this skill improve code quality?

It enforces a strict TDD cycle for every task: write a failing test, run it, write minimal code to pass, and verify. This prevents technical debt and ensures functional correctness.

Can I use the plans generated by this skill with other agents?

Yes, the skill is specifically designed to hand off plans to the `executing-plans` or `subagent-driven-development` skills for automated implementation.

Productividad y Flujo de Trabajo

Generates granular, test-driven implementation plans that break complex features into bite-sized, executable tasks.

Acerca de

The Advanced Implementation Planner skill transforms Claude into a senior technical architect capable of drafting exhaustive roadmaps for complex software tasks. By enforcing rigorous engineering standards such as Test-Driven Development (TDD), DRY, and YAGNI, it ensures every code change is preceded by a failing test and followed by a minimal, passing implementation. This skill is essential for maintaining codebase integrity and providing clear, unambiguous instructions for either human developers or AI subagents to follow, complete with exact file paths and shell commands.

Características Principales

5 GitHub stars
Granular Task Decomposition: Breaks down complex features into manageable 2-5 minute atomic actions.
Seamless Execution Handoff: Integrated workflows for transitioning plans to subagents or parallel execution sessions.
TDD-First Planning: Automatically mandates the creation of failing tests before any feature code is written.
Precise File Mapping: Identifies exact file paths and specific line ranges for every proposed modification.
Automated Documentation: Saves structured markdown plans to a dedicated docs/plans/ directory for version control.

Casos de Uso

Ensuring high test coverage during complex refactoring tasks through mandatory TDD cycles.
Architecting large-scale feature additions that span multiple modules and directories.
Generating standardized onboarding documentation for new developers or AI agents with zero codebase context.
