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.

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 | $0.00080 | $0.03553 |
| Opus 5 | $0.00040 | $0.01776 |
| Sonnet 5 | $0.00016 | $0.00711 |
| Haiku 4.5 | $0.00008 | $0.00355 |
Grade A, and why
unity-ai-navigation 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 8d 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 6 AI and Navigation Guide
Source: Unity 6.3 LTS Documentation (6000.3)
AI Navigation Overview
Package: com.unity.ai.navigation (v2.0.11 for Unity 6000.3)
The AI Navigation package is a high-level component system that enables NavMesh-based navigation and pathfinding. It supports runtime and edit-time NavMesh construction, dynamic obstacle management, and link systems for specialized actions (jumping, doors).
Core Components
| Component | Purpose |
|---|---|
| NavMeshSurface | Defines and builds NavMesh for a specific agent type |
| NavMeshAgent | Character pathfinding and movement |
| NavMeshObstacle | Dynamic obstacle avoidance |
| NavMeshModifier | Affects NavMesh generation based on transform hierarchy |
| NavMeshModifierVolume | Affects NavMesh generation based on volume |
| NavMeshLink | Connects same or different NavMesh surfaces |
NavMesh Setup
Baking a NavMesh
- Add a NavMeshSurface component to a GameObject
- Configure the Agent Type (determines which agents can use this surface)
- Set Use Geometry to Render Meshes or Physics Colliders
- Configure Collect Objects mode (All, Volume, Current Hierarchy, NavMeshModifier only)
- Click Bake or call
BuildNavMesh()at runtime
NavMeshSurface Properties
| Property | Description |
|---|---|
| Agent Type | Which NavMesh Agent configuration can use this surface |
| Default Area | Walkable (default), Not Walkable, Jump, plus 29 custom types |
| Use Geometry | Render Meshes or Physics Colliders (colliders allow closer edge navigation) |
| Generate Links | Auto-creates connections between collected GameObjects during bake |
| Collect Objects | All GameObjects, Volume, Current Hierarchy, NavMeshModifier only |
| Include Layers | Filters GameObjects by layer (default: Everything) |
Advanced Baking Parameters
| Parameter | Description |
|---|---|
| Override Voxel Size | Precision (default: 3 voxels per agent radius) |
| Override Tile Size | Tile dimensions (default: 256 voxels); smaller = better carving |
| Minimum Region Area | Removes disconnected mesh segments below threshold |
| Build Height Mesh | Generates elevation data for character placement |
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-ai-navigation is a skill published in the GitHub repository Nice-Wolf-Studio/unity-claude-skills (30 stars, last pushed 1mo ago), licensed MIT. It adds 80 tokens to every session and 3,553 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.
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.
