What it does
Gm Evaluate is an agent skill from RandallLiuXin/GodotMaker. Evaluate the current tag's quality: enforce the playable-closed-loop gate, maintain a single cross-tag e2e/ suite that always reflects the current game (add tests for new mechanics, prune tests for mechanics this tag deliberately removed), and reason about gameplay quality. Independent from the build process — fresh perspective on the final product. Explicit invocation only — use /gm-evaluate.
Its SKILL.md is about 4.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering End-to-end testing and Game development. The repository describes itself as: Autonomous text-to-game pipeline for Godot, powered by Claude Code,Codex,Opencode.
When your agent uses it
- Tasks that involve End-to-end testing
- Tasks that involve Game development
Example prompts
- “/gm-evaluate”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Understand Requirements
- Maintain the e2e/ suite
- Mandatory Checks
- Gameplay Reasoning
- Final Assessment (Pass/Fail)
What it can do on your machine
Read from SKILL.md and the folder at commit 1d4702c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gitpython
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Gm Evaluate loads about 4.7k tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 2,092 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,092 words (~4,656 tokens).

When should I use Gm Evaluate?
Gm Evaluate fits situations like: tasks that involve End-to-end testing; tasks that involve Game development.
How do I install Gm Evaluate in Claude Code?
Run `npx skills add RandallLiuXin/GodotMaker --skill gm-evaluate -a claude-code`. Or copy the skill folder (skills/core/gm-evaluate in RandallLiuXin/GodotMaker) into .claude/skills/gm-evaluate in your project. Claude Code loads it when a task matches its description.
How do I install Gm Evaluate in Codex?
Run `npx skills add RandallLiuXin/GodotMaker --skill gm-evaluate -a codex`. Or copy the skill folder (skills/core/gm-evaluate in RandallLiuXin/GodotMaker) into .agents/skills/gm-evaluate in your project. Codex loads it when a task matches its description.
Can I use Gm Evaluate in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add RandallLiuXin/GodotMaker --skill gm-evaluate -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gm-evaluate, .gemini/skills/gm-evaluate, .github/skills/gm-evaluate and .opencode/skills/gm-evaluate in your project.
What does Gm Evaluate need to run?
Going by SKILL.md and its folder, Gm Evaluate needs the command-line tools its instructions call (git and python).
Does Gm Evaluate access the network?
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
