What it does
Gm Dungeon is an agent skill from Sstobo/Claude-Code-Game-Master. Dungeon exploration — lightweight (narrative, default) vs structured (per-room JSON) modes, exit/obstacle handling, and ASCII map symbols. Load when the party enters a cave, ruin, or underground complex.
Its SKILL.md is about 390 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 AI & LLM Engineering, covering Structured output and tool calling. The repository describes itself as: Total conversion for Claude Code. Use RAG and the RPG ruleset apis to play a persistent adventure in any book or world of your choosing.
When your agent uses it
- Tasks that involve Structured output and tool calling
Example prompts
- “/gm-dungeon”
What it can do on your machine
Read from SKILL.md and the folder at commit dea9931. 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:
bash
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
Gm Dungeon loads about 388 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 153 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 153 words (~388 tokens).
“Enter → describe entrance + visible exits → explore (draw a map only when tactically useful, not every room) → combat by zone → on exit update master notes if significant.”
