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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Agent Snooping · line 11 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00035 | $0.00927 |
| Opus 5 | $0.00017 | $0.00464 |
| Sonnet 5 | $0.00007 | $0.00185 |
| Haiku 4.5 | $0.00003 | $0.00093 |
Grade A, and why
unity-ugui-authoring 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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity uGUI Authoring
For UXML, USS, UIDocument, or VisualElement work, use
unity-uitoolkit-authoring instead.
Read .claude/skills/unity-mcp-operations/SKILL.md once if it is not already
loaded. Enable UGUI when these tools are gated.
Tool Map
| Tool | Use |
|---|---|
create_ui |
Create a Canvas, Panel, Button, Text, Image, Toggle, Slider, InputField, or ScrollView |
set_rect |
Set anchors, position, size, pivot, offsets, or World Space depth |
lint_ugui |
Check EventSystem and Canvas GraphicRaycaster requirements |
ui_intent |
Draft a uGUI hierarchy from a template or natural-language intent |
list_events |
Inspect a persistent UnityEvent listener after wiring |
list_events is shared with component authoring. Resolve the live schema before
using an unfamiliar parameter.
Deterministic Workflow
- Inspect the existing Canvas and hierarchy.
- Mark the console.
- Create controls with stable names.
- Set anchors and constraints before pixel offsets.
- Inspect the resulting
RectTransformfields. - Run
lint_ugui, verify event listeners, and check the console delta. - Use a screenshot only for layout and appearance acceptance.

render_mode accepts SSO (Screen Space Overlay, the default), SSC (Screen
Space Camera), or WorldSpace. For a World Space Canvas, use set_rect.pos3 to
set anchoredPosition3D; it takes precedence over pos. font_min and
font_max enable TextMeshPro autosizing for a Text element.
What ships with it
1 file 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-ugui-authoring is a skill published in the GitHub repository german-krasnikov/unity-biome-mcp (29 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 927 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.
