Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00055 | $0.00539 |
| Opus 5 | $0.00028 | $0.00269 |
| Sonnet 5 | $0.00011 | $0.00108 |
| Haiku 4.5 | $0.00006 | $0.00054 |
Grade A, and why
zork 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 4d 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.
What it actually says
Zork Interactive Fiction Skill
Play the classic text adventure Zork I via dfrotz, with persistent save state and optional Obsidian integration for capturing learnings.
Quick Reference
| Command | What it does |
|---|---|
/zork look |
Look around current room |
/zork go north |
Move north (or any direction) |
/zork take lamp |
Pick up an item |
/zork inventory |
Check what you're carrying |
/zork |
Show current status (look + inventory) |
/zork new |
Start a fresh game |
/zork setup |
Configure Obsidian vault for sync |
How to Play
Execute a single command:
bash scripts/play.sh "go north"
Check current status:
bash scripts/status.sh
Start a new game:
bash scripts/new.sh
Configure Obsidian sync:
bash scripts/setup.sh /path/to/your/vault
Game State
- Save file:
state/claude.sav.qzl- automatically saved after each command - Transcript: Append-only log of all commands and responses
- Learnings: Your observations about the game (update with /zork reflect)
Obsidian Integration
If configured, transcript and learnings sync to your Obsidian vault as:
Claude Plays Zork Transcript.mdClaude Plays Zork Learnings.md
Run bash scripts/setup.sh to see current config or set a vault path.
Tips
- Classic text adventure verbs:
look,examine,take,drop,open,close,go,inventory - Directions:
north,south,east,west,up,down,ne,nw,se,sw - You can abbreviate:
nfor north,ifor inventory,lfor look - Save happens automatically after each command
Purpose
This skill helps Claude build experiential intuition about text adventures and parser conventions, informing the design of AI companions in Emergent Quest.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

zork is a skill published in the GitHub repository jonathanprozzi/claude-utils (11 stars, last pushed 6mo ago), licensed MIT. It adds 55 tokens to every session and 539 once invoked, about $0.0003 per session on Opus 5. 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 2026-08-30.
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-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.
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.
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
