A Dungeon Master skill for running an ongoing Dungeons & Dragons 5th Edition campaign, a tabletop role-playing game with shared rules for characters, actions, and combat. It emphasizes atmospheric descriptions, distinctive non-player characters, and consequences for player choices.

Use it to describe scenes, speak for characters, make rulings, and continue a persistent D&D 5e story.

It provides a consistent style and approach for guiding a campaign, so scenes, characters, and rulings feel connected over time.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00071	$0.11810
Opus 5	$0.00036	$0.05905
Sonnet 5	$0.00014	$0.02362
Haiku 4.5	$0.00007	$0.01181

Security

Grade A, and why

dnd scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 15 executable files (display/audio.py, display/autorun_wait.py, display/check_input.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
