Plan a feature across a whole repository
Let Claude Code explore the codebase itself before proposing an implementation plan.
What this prompt helps you do
A plan naming the files to change, the patterns to follow, the risks, and a validation path.
When to use it
A feature touches unfamiliar parts of a codebase and guessing the structure would be expensive.
What to prepare
The goal, relevant source material, constraints, examples, and the decision or action this should support.
How to get a strong result
Require it to cite the files it read; a plan that names no real files was written from assumptions.
How to use this prompt
Replace each placeholder with accurate context. Paste the complete prompt into Claude, review the response critically, resolve important questions, and use it as a considered input to the next decision—not as an unchecked final answer.
