How do you handle cascade failures when Claude Code edits shared files?
Been using Claude Code heavily for a full-stack TypeScript project (~180 files). It’s fantastic for feature work, but I kept running into a recurring issue: cascade failures.
When Claude edits a core file — shared utilities, type definitions, router configs — it has no awareness of downstream dependencies. A small signature change in `utils/auth.ts` can quietly break 10–20 files across services, middleware, and tests.
I used to run a full build after every AI edit. That helped, but it’s reactive and slow. And sometimes I’d still miss something until later.
So I started experimenting with a different approach: feeding Claude a live dependency graph and running lightweight impact analysis before allowing file edits.
The idea is simple:
- Before modifying a file, compute affected nodes
- Classify impact as PASS / WARN / FAIL
- If WARN or FAIL, surface the exact files that must be updated together
This reduced cascade debugging time dramatically.
Curious — how are others handling this?
Do you rely purely on rebuild cycles, or have you added any dependency awareness into your workflow?
