At a glance

Implement game mechanic functions via worker dispatch. An agent skill from RandallLiuXin/GodotMaker.

  • Works in 3 steps: Process Verify Feedback → Dispatch Workers (until PLAN is clean) → Verify + Review Pass
  • Tasks that involve Game design
  • SKILL.md covers Session Setup, Resume Check, Hard Rules and Honest Reporting, plus 8 more sections
  • Calls git and python

What it does

Gm Build is an agent skill from RandallLiuXin/GodotMaker. Implement game mechanic functions via worker dispatch. Covers risk-first then main implementation. Dispatches workers until PLAN is clean, then runs one verify+review pass; loops until convergence. Explicit invocation only — use /gm-build.

Its SKILL.md is about 3.5k 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 Game Development, covering Game design 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 Game design
  • Tasks that involve Game development

Example prompts

  • “/gm-build”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Process Verify Feedback
  2. Dispatch Workers (until PLAN is clean)
  3. Verify + Review Pass

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:

    • git
    • python

    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 Build loads about 3.5k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 1,769 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k

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 1,769 words (~3,487 tokens).
