What it does

Card Kit is an agent skill from RandallLiuXin/GodotMaker. Produce reusable card art sources and native Godot card UI resources.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `fixtures/representative-request.json`, `fixtures/representative-result.json` and `standalone_validation.py`).

It sits in Game Development, covering Game development. It works with Godot. 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 development

Example prompts

  • “/card-kit”

Requirements

  • Python 3

Workflow steps

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

  1. Plan and generate the visual source
  2. Process and curate
  3. Compile native resources
  4. Diagnose, repair, and recheck

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

    Ships script files (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Card Kit loads about 1.8k tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 948 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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 948 words (~1,812 tokens).

“Use this Skill for reusable non-pixel-art, card-game-specific UI: card frames, portrait frames, rarity frames, card/deck slots, resource badges, state overlays, card panels, and card buttons. It produces art sources and native Godot resources, not card rules, deck logic, a Control…”
