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 | $0.00073 | $0.05123 |
| Opus 5 | $0.00036 | $0.02561 |
| Sonnet 5 | $0.00015 | $0.01025 |
| Haiku 4.5 | $0.00007 | $0.00512 |
Grade A, and why
unity-2d 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 6d 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.

Unity 2D Development
2D Project Setup
Unity supports dedicated 2D project creation. When starting a 2D project:
- Select the 2D template (or 2D (URP) for 2D lighting support) when creating a new project
- The 2D template auto-installs required packages: 2D Sprite, 2D Tilemap Editor, 2D Animation
- The Scene view defaults to orthographic (top-down XY plane)
- The camera is set to Orthographic projection by default
- Imported images default to Sprite (2D and UI) texture type
Core 2D subsystems from the docs:
- Sprites: "2D graphic objects" -- the foundation for 2D games
- Tilemaps: "A GameObject that allows you to quickly create 2D levels using tiles and a grid overlay"
- 2D Physics: Dedicated physics system with 2D-optimized components
- 2D Rendering in URP: 2D lights, lighting effects, and pixelated visual styles

Sprites and SpriteRenderer
Sprite Assets
Sprites are "a type of 2D asset you can use in your Unity project." They function as 2D graphic objects with specialized import and management features. The 2D Sprite package must be installed (included with 2D templates).
Key sprite capabilities:
- Import sprites or spritesheets from textures
- Use the Sprite Editor to cut sprites from textures (slicing)
- Apply cropping to remove transparent areas
- Create collision geometry for sprite physics
- 9-slicing for reusing sprites at various sizes
- Masking to hide or reveal parts of a sprite or group of sprites
Source: https://docs.unity3d.com/6000.3/Documentation/Manual/sprite/sprite-landing.html
SpriteRenderer Component
The SpriteRenderer component controls how sprites display in scenes. Key properties:
| Property | Description |
|---|---|
sprite |
The Sprite asset to render |
color |
Tint color applied to the sprite (default: white = no tint) |
flipX / flipY |
Flip the sprite along an axis without moving the Transform |
drawMode |
Simple, Sliced, or Tiled |
size |
Dimensions when using Sliced or Tiled draw modes |
sortingLayerName |
Name of the renderer's sorting layer |
sortingOrder |
Priority within a sorting layer (lower renders first) |
maskInteraction |
None, Visible Inside Mask, or Visible Outside Mask |
spriteSortPoint |
Center or Pivot -- determines sort distance from camera |
What ships with it
2 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.

unity-2d is a skill published in the GitHub repository Nice-Wolf-Studio/unity-claude-skills (30 stars, last pushed 1mo ago), licensed MIT. It adds 73 tokens to every session and 5,123 once invoked, about $0.0004 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-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.
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…
