Validate the diagnostic

Confirm the reported code matches this rule before you edit it.

Confirm the reported code matches react-doctor/no-oversized-long-heading. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.

Compare the code

The corrected pattern shows a focused way to address the diagnostic.

Reported pattern

<h1 className="text-8xl">
  Understand every React diagnostic before your next release
</h1>;

Corrected pattern

<h1 className="text-5xl">
  Understand every React diagnostic before your next release
</h1>;

How to fix

Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.

Copyable fix prompt

Copy this self-contained prompt into your coding agent after you confirm the diagnostic.

Fix every confirmed react-doctor/no-oversized-long-heading diagnostic in the current repository. Required change: - Reduce the display size for sentence-length headlines, or tighten the copy before using a hero scale.

Reference transformation:Before:

<h1 className="text-8xl">
  Understand every React diagnostic before your next release
</h1>;

After:

<h1 className="text-5xl">
  Understand every React diagnostic before your next release
</h1>;

Constraints: - Confirm the reported code matches the Before pattern. - Make the smallest change that fixes the root cause. - Preserve behavior and interfaces unrelated to this diagnostic. - Reuse existing project components, utilities, and conventions. - Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations. - Use existing brand assets, product facts, content, and design tokens. - Do not invent claims, customer data, typefaces, or artwork. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. Verification: - Run focused tests for the changed behavior. - Run React Doctor and confirm this diagnostic no longer appears. - Report the files changed and any checks you could not run.
