optimize-web
Optimizes Unity WebGL and WebGPU builds for smaller downloads, faster loading, and smoother browser performance. Use when asked to shrink a web build, speed up its load, or fix stutter, memory or battery problems in the browser.
Install
With your agent
Install OMGSkills skill "unity-technologies/skills:optimize-web" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/Unity-Technologies/skills /tmp/skills && ln -s /tmp/skills/skills/optimize-web ~/.claude/skills/optimize-webFrom README
Important Use the unity cli (unity command --format json) and the unity-cli skill for each step. Use unity-pipeline too when it is available. Before making changes, establish a baseline of the current behavior so you can tell whether a later result is actually caused by your change. Create a restore point you can roll back to if your changes fail. Do only what's asked. Don't change unrelated assets or files. If the changes affect runtime behavior, add Debug.Log lines that will prove the actual scene behaviour (not just your changes) is now working - you'll read these when you enter Play mode to validate later. For example, log a GameObject's Transform scale if your fix is meant to make sure it changes size. Avoid long explanations. Performance Notes Take your time to do this thoroughly. Quality is more important than speed.
