Multi-file Editing
Claude Code becomes most useful when the task crosses file boundaries.
Typical examples:
- frontend and backend type changes
- route updates plus UI fixes
- content changes plus metadata updates
- refactors that also need test and documentation updates
Why multi-file work is different
Single-file edits are easy to patch manually. Multi-file work is where an agent can genuinely save time by:
- finding all affected files
- keeping naming and logic consistent
- updating related layers in one pass
- running checks after the edits land
How to steer it safely
- ask it to inspect before editing
- define the write scope
- mention files that should remain untouched
- require verification after the changes
Good prompt:
Update the wiki static loader to support .en.md fallback, then wire the locale through the page components. Do not change unrelated routing behavior.
That is much safer than simply saying "make the wiki bilingual."
