⚠️ Potential issue | 🔴 Critical

Critical: || true silences all lint failures, breaking CI enforcement.

The || true suffix causes the lint scripts to always exit with code 0, regardless of lint errors. This means:

  • CI pipelines will never fail on lint violations
  • Pre-existing and new lint errors will be silently ignored

While the PR notes that migrating to ESLint CLI surfaces pre-existing issues, suppressing all failures is not the right solution—it effectively disables linting as a quality gate.

Suggested alternatives

Option 1 (Recommended): Remove || true and fix pre-existing lint errors:

-    "lint": "eslint pages components context utils types --ext .js,.jsx,.ts,.tsx || true",
-    "lint:fix": "eslint pages components context utils types --fix --ext .js,.jsx,.ts,.tsx || true",
+    "lint": "eslint pages components context utils types --ext .js,.jsx,.ts,.tsx",
+    "lint:fix": "eslint pages components context utils types --fix --ext .js,.jsx,.ts,.tsx",

Option 2: Use --max-warnings to allow warnings but fail on errors:

-    "lint": "eslint pages components context utils types --ext .js,.jsx,.ts,.tsx || true",
+    "lint": "eslint pages components context utils types --ext .js,.jsx,.ts,.tsx --max-warnings=100",

Option 3: Temporarily downgrade problematic rules to warnings in .eslintrc and address them incrementally.

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In `@package.json` around lines 17 - 18, The lint scripts ("lint" and "lint:fix")
currently append "|| true", which masks failures and prevents CI from failing on
lint errors; remove the "|| true" suffix from both "lint" and "lint:fix" in
package.json so ESLint exits non‑zero on errors (or alternatively replace it
with a controlled flag such as --max-warnings=0 if you want to allow warnings
but fail on errors), then run the linter (and fix) locally and resolve the
surfaced issues or temporarily relax rules in .eslintrc while addressing them.
