optimize-web
by Unity-Technologies
Optimizes Unity 6 WebGL and WebGPU builds for smaller download size, faster initial load, and efficient browser runtime performance. Use when the user's web build is too large, stutters in a specific browser, consumes excessive battery, needs CDN/server compression configured, or needs guidance on resource stripping, shader variant reduction, KTX textures, quality settings, or web profiling.
levelplay-unity-integration
by Unity-Technologies
Adds ads and monetization to a Unity game using the LevelPlay Mediation SDK (installed via the Ads Mediation UPM package). Use when a developer asks about adding ads to a Unity game, implementing rewarded, interstitial, or banner ads, setting up ad mediation, configuring ad networks, installing or updating the Ads Mediation package, troubleshooting LevelPlay namespace errors, resolving Android gradle or iOS CocoaPods dependency issues for ads, configuring ATT or privacy settings for ad compliance, tracking impression-level revenue (ILRD), initializing the LevelPlay SDK, or setting up ad unit IDs. Also use when a developer wants to monetize their Unity game with ads, asks how to get started with LevelPlay, ads, or mediation, or needs help with any part of the LevelPlay integration workflow including platform-specific setup for iOS or Android. Also use when upgrading the LevelPlay or IronSource SDK version, migrating from deprecated IronSource.Agent APIs, or migrating a game from Unity Ads to LevelPlay.
assets
by arabold
Use when discovering, downloading, or adding new 3D/2D/audio assets to this game from curated free sources (KayKit, Quaternius, Kenney, Poly Pizza) or generating our own via image-to-3D. Covers the two automation channels (KayKit GitHub + Poly Pizza API), the download->manifest->import workflow, licensing/style rules, and the experimental AI authoring path. Policy and the asset manifest live in assets/AGENTS.md; this skill is the how-to and the scripts. Not needed for editing assets already in the repo.
godot-test
by Chen19007
Run GUT unit tests for Godot projects. Use when: (1) Running unit tests, (2) Verifying code changes, (3) TDD development, (4) CI/CD testing.
