Agent Quick Fix

Repair against the current Vite contract, then keep the change narrow and source-backed.

Product: Vite
Current-contract area: Vite 8 plugin assumes Rollup-only hook behavior
Likely root cause: A custom plugin builds under Vite 7 but fails or emits wrong chunks under Rolldown.
Repair direction: Verifier checks the current package identity/config format and a real transformed output. Check emitted assets and runtime behavior across the supported target.

Symptom

A custom plugin builds under Vite 7 but fails or emits wrong chunks under Rolldown.

Why This Happens

The old package/config name is syntactically valid, but current tool packaging and discovery rules live in external release documentation.

Common Wrong Fixes

  • Changing local code without checking the current external contract.
  • Retrying the same install, build, or API call with no version/source change.
  • Applying a broad unsafe bypass when a narrow compatibility fix is available.
