Validate the diagnostic

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

Confirm the reported code matches react-doctor/three-shader-no-redeclared-builtins. 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

attribute vec3 position;
uniform mat4 modelViewMatrix;
void main() {
  gl_Position = modelViewMatrix * vec4(position, 1.0);
}

Corrected pattern

void main() {
  gl_Position = modelViewMatrix * vec4(position, 1.0);
}

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/three-shader-no-redeclared-builtins diagnostic in the current repository. Required change: - Use ShaderMaterial built-in attributes and uniforms without redeclaring them.

Reference transformation:Before:

attribute vec3 position;
uniform mat4 modelViewMatrix;
void main() {
  gl_Position = modelViewMatrix * vec4(position, 1.0);
}

After:

void main() {
  gl_Position = modelViewMatrix * vec4(position, 1.0);
}

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. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. - Confirm this rule is enabled for the project: three. 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.
