Find every caller before changing a signature
Locate all real usages across the repository instead of trusting a text search.
What this prompt helps you do
A complete caller inventory with each call site, its context, and the change each one needs.
When to use it
A widely used function or interface needs its signature changed.
What to prepare
The goal, relevant source material, constraints, examples, and the decision or action this should support.
How to get a strong result
Include dynamic and indirect calls; a grep-based inventory misses exactly the callers that break at runtime.
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.
