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 5.1 | $0.00145 | $0.02473 |
| Opus 5 | $0.00072 | $0.01236 |
| Sonnet 5 | $0.00029 | $0.00495 |
| Haiku 4.5 | $0.00015 | $0.00247 |
Grade A, and why
unity-puzzle 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.
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 — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity Challenge & Puzzle Designer
Build challenges that teach, test, and carry meaning — one idea at a time
When to Use This Skill
- Designing a specific challenge or puzzle around an existing mechanic
- Designing combat encounters, environmental puzzles, or skill-based challenges
- Sequencing multiple challenges within a level section
- Ensuring a challenge teaches without frustrating
- Writing a complete challenge proposal for review
- Diagnosing why an encounter feels unclear or unfair
Design the mechanic first using
unity-mechanics(this plugin). Place the challenge in a level usingunity-level(this plugin). Tie the challenge to a story beat usingunity-narrative(this plugin). Generate raw challenge ideas usingunity-brainstorming(standalone skill).
Core Philosophy
One Idea Per Challenge
Every challenge tests exactly one concept. If a challenge requires two new ideas simultaneously, split it into two challenges. Complexity comes from combinations of already-understood concepts — not from stacking unknowns.
The Fairness Contract
All information needed to overcome the challenge must be available before the player commits to an attempt. No hidden elements. No logic that contradicts established rules. If the player fails, it must be because they misread the situation — not because the game withheld information.
Challenges Are Teachers
Every challenge exists to deepen the player's understanding of a mechanic, the world, or the system. Before designing a challenge, answer: "What will the player know after completing this that they didn't know before?"
Challenge Types by Genre
This skill covers all forms of gameplay challenges:
| Challenge type | Genres | Core design question |
|---|---|---|
| Environmental puzzle | Platformer, adventure, puzzle | How does the player manipulate the space to progress? |
| Combat encounter | Action, RPG, shooter | How does the enemy composition test the player's abilities? |
| Traversal challenge | Platformer, action | How does the space test the player's movement skills? |
| Stealth section | Stealth, action-adventure | How does observation and timing create tension? |
| Resource puzzle | Strategy, survival, RPG | How does scarcity force meaningful decisions? |
| Social / dialogue challenge | RPG, visual novel | How does information and choice create meaningful outcomes? |
| Timing / rhythm challenge | Rhythm, action | How does pattern recognition and execution create flow? |
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.

unity-puzzle is a skill published in the GitHub repository sonereraslan/local-marketplace (2 stars, last pushed 4mo ago), licensed MIT. It adds 145 tokens to every session and 2,473 once invoked, about $0.0007 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 2026-08-31.
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).
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…
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
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.
