Game Testing, QA & Release Skills for AI Agents
Skills that make your agent prove a build works before calling it done: run tests headless, profile before optimizing, check assets for defects and walk through a launch checklist.
29 free skills, MCP servers and kits
Pick a Testing & QA skill to start with
Launch Checklist (Claude Code Game Studios)
Launch readiness across every department: code, content, store, marketing, community, infrastructure, legal, go/no-go sign-offs.
Playtest Report (Claude Code Game Studios)
Structured playtest report template, or turn existing playtest notes into structured feedback.
Game Performance Optimization
Fix performance methodically: profile first, set a frame budget, find the CPU or GPU bottleneck, then pool, batch and cut allocations.
Godot Export
Export Godot 4.7 games for desktop, web and mobile: export presets, headless CLI builds for CI, web COOP/COEP and server builds.
Godot Headless Testing
Run GDScript test suites from the command line with `godot --headless`, using a SceneTree/MainLoop runner script that exits non-zero on failure so CI can gate merges.
Unity Project Auditor Fixes
Instructions for how to use Project Auditor to find and fix a list of issues.
Unity WebGL Optimization
Optimizes Unity WebGL and WebGPU builds for smaller downloads and faster load.
Novel to Game: QA
Verify a game with evidence on its selected target runtime.
What a Testing & QA skill gives your agent
Measure first
Performance skills start from the profiler and a frame budget, then pick the fix, instead of guessing.
Evidence over opinion
QA skills ask for real renders, real input and a completed loop, and say clearly what was not checked.
Ship-ready builds
Export, web build optimization and launch checklist skills cover the last mile to Steam, itch.io and the browser.
How to use a game dev skill
Three steps in Claude Code, Codex, Cursor or any agent that reads SKILL.md.
- 01
Install it
Run the command on the skill's page, or copy the install prompt and let your agent run it.
- 02
Ask in plain words
Describe what you want. The agent loads the skill when your request matches, or you can call it by name.
- 03
Review and play
Run the game, read what the agent changed, and ask for fixes in the same session.
Why use a skill instead of a prompt?
A prompt is gone after one chat. A skill stays in your project: the agent reads the same checklist, engine rules and pitfalls every time the task comes up, so the results stay consistent and you stop repeating yourself.
All Testing & QA skills
