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 | $0.00016 | $0.00464 |
| Opus 5.5 | $0.00006 | $0.00186 |
| Sonnet 5.5 | $0.00003 | $0.00093 |
| Haiku 4.5 | $0.00002 | $0.00046 |
Grade A, and why
unity-package 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 1mo 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
Package Management
Do not use Unity_RunCommand for package operations. Unity's MCP server exposes first-class package tools that cover every operation in this domain directly.
Routing
| Operation | Tool | Typical payload |
|---|---|---|
| List installed packages | Unity_PackageManager_GetData |
{ "installedOnly": true } (no packageID) |
| Check a specific package | Unity_PackageManager_GetData |
{ "packageID": "com.unity.cinemachine", "installedOnly": true } |
| List a package's versions | Unity_PackageManager_GetData |
{ "packageID": "com.unity.cinemachine", "installedOnly": false } |
| List a package's dependencies | Unity_PackageManager_GetData |
{ "packageID": "com.unity.timeline", "installedOnly": false } |
| Install a package | Unity_PackageManager_ExecuteAction |
{ "action": "Add", "packageID": "com.unity.cinemachine" } (optional version) |
| Remove a package | Unity_PackageManager_ExecuteAction |
{ "action": "Remove", "packageID": "com.unity.splines" } |
| Refresh / resolve | Unity_PackageManager_ExecuteAction |
{ "action": "Resolve" } |
| Embed a local copy | Unity_PackageManager_ExecuteAction |
{ "action": "Embed", "packageID": "com.unity.cinemachine" } |
| Import a package sample | Unity_PackageManager_ExecuteAction |
{ "action": "Sample", "packageID": "...", "sampleName": "..." } |
Notes
- Install / remove operations are asynchronous on Unity's side. If the tool returns a "pending" status, poll
Unity_PackageManager_GetDatawithinstalledOnly: truea few seconds later to observe the final state. - Package operations can trigger a Domain Reload. Expect transient server unavailability afterward; retry once.
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-package is a skill published in the GitHub repository batihandev/unity-mcp-skills (6 stars, last pushed 12d ago), licensed MIT. It adds 16 tokens to every session and 464 once invoked, about $0.0001 per session on Opus 5.5. 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.

unity-csharp
A set of practical guidelines for writing Unity game scripts in C#. Unity is a game engine, and these rules cover its update loop, object lifetime, memory cleanup, coroutines, and editable data.
script-execute
Compiles and runs C# in the Unity Editor (Roslyn): plain statements with the last expression as the result, or a full class with a static method. See the skill body for the modes, usings/include and Unity object parameters.
pufferlib
This skill should be used when working with reinforcement learning tasks including high-performance RL training, custom environment development, vectorized parallel simulation, multi-agent systems, or integration with existing RL environments (Gymnasium, PettingZoo, Atari, Procgen, etc.). Use this skill for…
script-update-or-create
Write a .cs script file (create or overwrite) with the provided C# code. Validates syntax via Roslyn before write — invalid code is rejected with error details and the file is left untouched. Refreshes the AssetDatabase and delivers the final result via requestId after Unity finishes the triggered compilation. Use…
godot-csharp
Use C#/.NET in Godot 4.7: partial classes extending nodes, the PascalCase lifecycle (Ready/Process/PhysicsProcess), [Export] fields, [Signal] delegates as C# events, type-safe node lookup, and calling between C# and GDScript. Use when writing Godot game code in C# (.cs files, .csproj), needing the Godot .NET build…
