Can I use this for existing codebases?

Yes, the skill is designed to work with existing projects by requiring exact file paths and specific line numbers for modifications.

Where are the generated plans saved?

All implementation plans are automatically saved as version-controlled Markdown files in the docs/plans/ directory of your repository.

How does it handle Test-Driven Development (TDD)?

The skill structures every task into five steps: write a failing test, verify the failure, write minimal code to pass, verify the pass, and commit the changes.

What is the main benefit of using the Writing Plans skill?

It prevents architectural drift and coding errors by forcing a 'plan-first' approach that defines granular, testable steps before implementation begins.

Does this skill write the production code automatically?

No, this skill focuses on the architecture and roadmap phase. Once the plan is saved, it hands off the execution to specialized skills like executing-plans or subagent-driven-development.

Productivity & Workflow

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

The Writing Plans skill acts as a technical architect for your AI coding sessions, transforming high-level requirements into a rigorous, step-by-step roadmap. It enforces professional development standards like Test-Driven Development (TDD), DRY, and YAGNI by documenting exact file paths, shell commands, and minimal code implementations before a single line of production code is touched. This skill is essential for maintaining architectural integrity in complex projects, ensuring that every task is documented, tested, and committed with precision.
