**1 issue found** across 11 files Confidence score: **3/5** - Runtime risk: `packages/evals/tasks/observe_file_input_upload.ts` uses a relative ESM import without the `.js` extension, which can fail under native ESM resolution and break this task at runtime. - Score reflects a concrete user-impacting runtime failure in an eval task, though the issue is localized and straightforward to fix. - Pay close attention to `packages/evals/tasks/observe_file_input_upload.ts` - missing `.js` extension on a relative ESM import.

P2: Missing `.js` extension on relative ESM import. All other eval task files in this directory use `"../types/evals.js"`. Omitting the extension will fail at runtime under native ESM resolution. (Based on your team's feedback about requiring explicit .js extensions on all relative ESM import specifiers.) [FEEDBACK_USED] ```
