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 | $0.00000 | $0.03675 |
| Opus 5 | $0.00000 | $0.01837 |
| Sonnet 5 | $0.00000 | $0.00735 |
| Haiku 4.5 | $0.00000 | $0.00367 |
Grade A, and why
create-adventure 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 9d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/create-adventure
Master directive skill. Given a high-level creative goal ("make me an adventure for 3rd level characters in a haunted forest"), orchestrate the full module-building pipeline by invoking sub-skills in sequence.
Core Philosophy: Black Box Adventure Creation
The create-adventure pipeline is a white-glove, spoiler-free experience. The user provides a prompt and gets back a playable module — they should know nothing about the plot, encounters, NPCs, puzzles, or story beats. The fun is in discovering it all during play.
Rules for the orchestrator:
- NEVER reveal plot details, encounter compositions, NPC names, quest objectives, puzzle solutions, or story twists to the user. Not in status updates, not in error messages, not in progress reports.
- Status updates must be vague and atmospheric. Say things like "The world is taking shape...", "Populating the tavern...", "Adding some surprises..." — never "Placing 3 goblins in the cave" or "Creating a quest where the blacksmith asks you to find his hammer."
- Sub-skills do NOT interact with the user. They are fully autonomous. If a sub-skill encounters a judgment call (too many monsters? unclear quest flow? conflicting placements?), the orchestrator makes the call — it does not ask the user. This introduces creative randomness, which is part of the fun.
- The orchestrator is the decision-maker. When a sub-skill would normally need guidance, the orchestrator uses its own judgment. Lean toward "more fun" over "perfectly balanced." A slightly overtuned encounter or an unexpected twist is better than a bland, safe adventure.
Pre-Flight (before invoking any sub-skill)
Heads up before we dive in: Building a full adventure takes a while — typically 20–40 minutes of autonomous work across 9 phases. To avoid constant approval prompts, consider enabling Bypass permissions mode:
- Desktop/VS Code: Settings → enable Allow dangerously skip permissions, then select Bypass permissions from the mode dropdown next to the send button.
- CLI: Launch with
claude --dangerously-skip-permissions- settings.json: Set
"permissions": { "defaultMode": "bypassPermissions" }Once pre-flight is done, the pipeline runs completely hands-free.
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.

create-adventure is a skill published in the GitHub repository Txpple/nwn-mcp (11 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,675 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
playtest-report
Generates a structured playtest report template or analyzes existing playtest notes into a structured format. Use this to standardize playtest feedback collection and analysis.
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
unity-manual-component
Manually add, configure, reorder, and copy components on GameObjects using Unity Editor UI. For one-off Inspector workflows that do not need REST automation.
