Which uniforms are automatically provided to the shader?

The tool automatically provides 'uniform float time' (set to 0.0), 'uniform vec2 resolution', and 'in vec2 fragTexCoord' for UV mapping.

What shader types does this skill support?

This skill primarily supports GLSL fragment shaders (.fs files) using the #version 330 specification, rendering them to static PNG images.

Can Claude analyze the generated output images?

Yes, by generating a PNG and using the Read tool, Claude can 'see' the shader output and provide specific advice on fixing visual bugs or coordinate issues.

Do I need a running game to test my shaders?

No, this skill uses a standalone Go-based rendering tool to output the shader result to a file without requiring your main application to be running.

Debugs GLSL fragment shaders by rendering visual outputs to PNG files for instant verification and troubleshooting.

The Shader Debugger skill streamlines GLSL development by allowing developers to render fragment shaders directly to static PNG images. This utility is essential for troubleshooting GPU rendering issues, verifying UV coordinate mapping, and inspecting shader math without the overhead of running a full game engine or simulation loop. By converting code logic into a visual artifact, it enables developers and AI assistants to analyze rendering artifacts, normalize coordinate systems, and isolate problematic shader code through rapid iteration.
