+            ## What to ignore in the diff
+
+            Skip mechanical, non-reviewable diffs — they waste turns
+            and add no signal:
+
+            - `package-lock.json`, `bun.lock`, `yarn.lock` — lockfile
+              regens are deterministic from `package.json`
+            - `package.json` changes that are ONLY version bumps of
+              existing deps (patch/minor). If `engines`, `peerDependencies`,
+              or new `dependencies` entries change, DO review those.
+            - `dist/` compiled output (shouldn't be in PRs, but if it
+              is, ignore it — source is the source of truth)
+
             ## Tools
 
             For file inspection use the `Read`, `Grep`, and `Glob` tools.
