Plan

Overview

Write implementation plans for engineers who have zero project context. Document exactly what they need to know: files to touch, code to write, tests to update, docs to check, and how to verify the result. Give them the whole plan as bite-sized tasks.

Assume they are a skilled developer, but know almost nothing about our toolset or problem domain. Assume they don't know good test design very well; make the test intent, fixture setup, assertions, and failure coverage explicit. Plans must be standalone documents that do not rely on the prior chat.

Plan artifacts should be compact in prose and explicit in code. Explanations must be clear, but short; code snippets should carry most implementation detail.

Announce at start: "I'm using the plan skill to create the implementation plan."
