D&D-kit leveling — XP thresholds, the level-up ceremony, hit dice by class, and ASI/feat/subclass handling.

What it does
Gm Levelup is an agent skill from Sstobo/Claude-Code-Game-Master. D&D-kit leveling — XP thresholds, the level-up ceremony, hit dice by class, and ASI/feat/subclass handling. Load when gm-player.sh xp reports LEVELUP in a dnd5e-kit campaign. Non-D&D kits advance via their ruleset progression model (milestone / resource-axis), not this table.
Its SKILL.md is about 350 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 Product & Project Management, covering Project management. 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.

Example prompts
- “/gm-levelup”
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
No scripts in the folder and no shell commands in SKILL.md.
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 Levelup loads about 345 tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 129 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 129 words (~345 tokens).
“STEP 0 — KIT GUARD. If the scene-context KIT block is not dnd5e, close this skill and advance through the kit's progression model.”
