UnitySkills is a REST API-based automation engine that lets AI coding agents control Unity Editor projects, including scenes and other editor operations. It is for developers using Unity with supported coding agents and IDEs. The catalogue skills and commands provide the agent workflows used to operate Unity projects through the engine.
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: 2 findings, up to high
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 →
- high Rogue Agent · line 24 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
- medium Excessive Agency · line 25 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00017 | $0.02510 |
| Opus 5 | $0.00009 | $0.01255 |
| Sonnet 5 | $0.00003 | $0.00502 |
| Haiku 4.5 | $0.00002 | $0.00251 |
Grade A, and why
unity-xr 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 6d 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 — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via
GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Unity XR Interaction Toolkit Skills
Use this module for XR Interaction Toolkit setup and configuration. All xr_* skills are reflection-based and support XRI 2.x on Unity 2022 and XRI 3.x on Unity 6+.
Requires:
com.unity.xr.interaction.toolkit. Hard rule: Read this file before the firstxr_*call in a session. Wrong property names can fail silently because the bridge is reflection-based.
Guardrails
Operating Mode (v1.9 three-tier):
- Approval (default): query/list/info skills (
xr_check_setup,xr_get_scene_report,xr_list_interactors,xr_list_interactables) run directly. Create/modify skills are FullAuto — onMODE_RESTRICTED, run the grant protocol; a successful/permission/grantexecutes the skill server-side and returns the result in the same response. - Auto / Bypass: SemiAuto and FullAuto run directly.
- This module contains no Delete / PlayMode / Reload /
RiskLevel="high"skills, so nothing is auto-classified as forbidden — every skill is reachable via grant. - When
com.unity.xr.interaction.toolkitis missing, everyxr_*skill returns theNoXRI()install instruction instead of executing. - Reflection-sensitive: property names on XRI components must match XRI 2.x/3.x exactly. A wrong field name on
xr_configure_interactable/xr_configure_haptics/xr_configure_interaction_layersis silently ignored. LoadAPI_REFERENCE.mdbefore issuing detailed property edits.
DO NOT (common hallucinations):
XRHand,XRPlayer,XRTeleporter,GrabInteractor,VRController,XRLocomotion, andXRManagerare not the runtime classes you want hereinteractable.OnGrab()/OnRelease()are not the XRI event model -> useselectEntered/selectExitedcontroller.vibrate()is not the documented route here -> configure haptics throughxr_configure_haptics- Do not assume physics Layer or Tag replaces
InteractionLayerMask - Do not guess component property names. Load
API_REFERENCE.mdbefore setting detailed XR component properties
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-xr is a skill published in the GitHub repository Besty0728/Unity-Skills (1,727 stars, last pushed today), licensed MIT. It adds 17 tokens to every session and 2,510 once invoked, about $0.0001 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 2026-09-03.
