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 | $0.00037 | $0.01703 |
| Opus 5 | $0.00018 | $0.00851 |
| Sonnet 5 | $0.00007 | $0.00341 |
| Haiku 4.5 | $0.00004 | $0.00170 |
Grade A, and why
unity-mcp-operations 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity MCP Operations
Use this skill as the shared operating contract for every Unity Biome MCP task. The live server schema and the current Unity state are authoritative.
Core Workflow
- Confirm the server and Editor state with
mcp_statuswhen connectivity or mode is uncertain. - Read the smallest useful scope. Start with a hierarchy summary, targeted
inspect, or one component rather than a full-scene dump. - Enable a gated category with its uppercase canonical name:
SCENE,COMPONENTS,ASSETS,MEDIA,UGUI,UITOOLKIT,VERIFY,RUNTIME,TESTS, orSYSTEM. For UI use the specific alias:discover_tools("ugui")ordiscover_tools("uitoolkit"). - Call
resolve_tool_schema(tools="<name>")before relying on a parameter you have not used in the current session. Do not reconstruct signatures from memory. - Mark the console before mutations when new errors would matter.
- Choose the narrowest aggregate tool that expresses the operation.
- Mutate, verify the changed state, and report evidence rather than a list of calls.
Before rebuilding a known repeated workflow, call list_skills(). Reuse a
matching learned MCP skill with use_skill(...) when its stored contract still
matches the current scene and schema.
Routing
| Need | Prefer |
|---|---|
| Same component across multiple objects | inspect(paths=..., components=..., fields=...) |
| Create several ordinary objects | setup_objects(specs=...) as a standalone call |
| Set properties across several objects | configure_objects(config=...) as a standalone call |
| Set several properties on one object | set_properties(path=..., props=...) |
| Several compatible synchronous Unity commands | batch(...) |
| Consumer-project NUnit run | One correlated run_tests_wait(...) call |
| Explicit nonblocking test dispatch or recovery | run_tests(...), then only get_test_run(run_id=...) for that exact run |
| Repeatable Play Mode scenario | run_playtest(...) or run_playtest_suite(...) |
| Stable repeated batch sequence | save_skill(...), then use_skill(...) |
| Stable parameterized scene scaffold | save_template(...), then apply_template(...) |
| Build a player | build(action="build", target="...") |
| UPM package operation | `package(action="list" |
| Lighting or occlusion bake | `bake(target="lighting" |
| Unknown or gated capability | discover_tools(...), then resolve_tool_schema(...) |
What ships with it
8 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-mcp-operations is a skill published in the GitHub repository german-krasnikov/unity-biome-mcp (29 stars, last pushed 2d ago), licensed MIT. It adds 37 tokens to every session and 1,703 once invoked, about $0.0002 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.
