A command-line control surface for a live Unity Editor or game player. Unity is a development environment for games and interactive 3D applications.

Use it to work with scenes, game objects, components, transforms, prefabs, materials, assets, play mode, screenshots, profiling, tests, and C# execution inside Unity.

It lets an agent inspect and change Unity project data through commands instead of relying only on manual editor actions.

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.

Token cost

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	$0.00105	$0.04335
Opus 5	$0.00053	$0.02167
Sonnet 5	$0.00021	$0.00867
Haiku 4.5	$0.00011	$0.00434

Security

Grade B, and why

unity-cli scanned grade B with 1 finding 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 yesterday.

The scan reads SKILL.md. This mod also ships 37 executable files (evals/benchmark.py, evals/live_contract.py, evals/run_routing_current.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 329 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Unity CLI

One CLI (cs) drives the Unity Editor/Player. The default authoring surface is grouped into six agent-facing domains so only the relevant schema enters context; control-plane and project custom commands use explicit views. cs list-commands is a control-plane CLI discovery operation, not the canonical package contract command/list. Its CLI flags are never command/list arguments, and discovery invocations must not be represented as canonical command routes. Only use command/list when the user explicitly requests that package contract. The records returned by discovery carry authoring, custom, or control-plane tiers.

Running `cs`

cs below means:

python "<SKILL_DIR>/scripts/cli/cs.py"

<SKILL_DIR> is this skill's absolute base directory, supplied when the skill loads. Expand cs to that absolute command on every call and run it without changing directory.

Do not enumerate other skill installations or run cs --help to rediscover this documented surface; this file and its returned Route Cards are complete for routing.

Do not pass --project during normal use. The CLI locates the Unity project by walking up from both the working directory and its own committed location. --project <path> is only for deliberately targeting a different project.

The CLI runs in place; there is no bootstrap or copy step. cs setup is a convenience, not a gate. If the package is absent or --update is used, setup writes the shared Packages/manifest.json. Before any write-producing setup, state the exact source it will add and obtain the user's approval. See references/setup.md.

Passing inputs

Never pass C# code or structured command parameters inline through the shell. Write a file, then pass its absolute path:

Raw C# for exec goes in a .cs file via --file.
Structured parameters for command and batch go in a JSON file via --input.

The mandatory scratch directory is:

<project-root>/Temp/CSharpConsole/AgentScratch/

Files

What ships with it

56 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.

Changes

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-cli is a skill published in the GitHub repository niqibiao/unity-cli-skill (41 stars, last pushed 8d ago), licensed Apache-2.0. It adds 105 tokens to every session and 4,335 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
