What it does
Unity Skills is an agent skill from Besty0728/Unity-Skills. Automate the Unity Editor through a local REST API — scripts, scenes, prefabs, assets, materials, lighting, tests and hundreds of other Editor operations. Use when the user wants to actually operate the Unity Editor from chat — create, modify or batch-edit GameObjects/scripts/scenes/assets, or run Editor automation — in any language. Not needed for conceptual Unity Q&A that touches no Editor state — read the matching advisory doc under skills/ instead. 当用户要从对话里实际操作 Unity 编辑器（创建/修改/批量编辑/运行测试）时使用，任何语言均可触发；纯概念问答无需本协议。
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 31 other files, including scripts and reference files (for example `SKILL_GUIDE.md`, `references/2d.md` and `references/3d.md`). Compatibility notes: Requires Unity Editor 2022.3+/6000.x with the UnitySkills package (local REST server on localhost:8090-8100); Python 3 for the bundled client
It sits in Game Development, covering REST APIs. It works with Unity. The repository describes itself as: AI automation skills specifically designed for Unity. The licence is MIT.
When your agent uses it
- The user wants to actually operate the Unity Editor from chat — create
- Batch-edit GameObjects/scripts/scenes/assets
- Run Editor automation — in any language
Example prompts
- “/unity-skills”
Requirements
- Python 3
- Compatibility (from SKILL.md): Requires Unity Editor 2022.3+/6000.x with the UnitySkills package (local REST server on localhost:8090-8100); Python 3 for the bundled client
What it can do on your machine
Read from SKILL.md and the folder at commit ec8aa7c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/, which the agent can run.
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Requires Unity Editor 2022.3+/6000.x with the UnitySkills package (local REST server on localhost:8090-8100); Python 3 for the bundled client
From compatibility in the SKILL.md frontmatter.
Context cost
Unity Skills loads about 2k tokens when it runs, and up to ~134k if it reads all its reference files. Until then it costs about 133 tokens; SKILL.md has 754 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Unity Skills
Docs are English-only: match requests to modules by meaning in any language, and always reply in the user's language.
Route first
- Automate — the user asked you to act, or it needs traversal, search, batch, exact numbers or many objects: drive the Editor via REST.
- Guide — the user wants to do it themselves, or
surfaceProfileisguide: name menus and Inspector fields per SKILL_GUIDE.md. - Advise — a design question that changes nothing: answer from the matching advisory doc (scriptdesign, architecture, patterns, all in the module index), no REST calls.
Target the right Editor
Ports 8090–8100 go first come, first served: add ?expectProject=<project> (productName or folder name) or the exact ?expectInstance=<instanceId> to every write. A different Editor answers 409 INSTANCE_MISMATCH and runs nothing.
GET /health (exempt from the check) has currentMode, surfaceProfile, dryRunPolicy, instanceId: probe it once in the same shell command as your first request, adding no other call, then only after a refused write, 409, 503/refused connection or odd mode. bypass and auto run writes directly, but under auto confirm ≥5-object batches, prefab apply, scene-level, asset-overwriting or irreversible changes with the user first (probe alone before those); approval gates FullAuto writes behind single-shot grants (permanent: the user's Allowlist).
During a domain reload the port answers 503 or refuses for seconds while its ~/.unity_skills/registry.json entry reads reloading: retry it, never another instance.
Quick reference
Every skill is POST /skill/<name> with JSON args:
curl -s "http://localhost:<port>/skill/gameobject_set_transform?expectProject=<project>" -d '{"name":"Crate","posX":4,"posY":1.5,"posZ":-2}'
Target objects by name or the exact path/instanceId (likewise parentPath, childPath); skip lookup calls — a wrong name fails the call and returns candidates.
| Call |
|---|
gameobject_create {name, primitiveType, parentName, x,y,z, rotX,rotY,rotZ, scaleX,scaleY,scaleZ, space} — x/y/z, rot local to the parent unless space:"world"; scale local |
gameobject_set_transform {name, posX,posY,posZ, rotX,rotY,rotZ, scaleX,scaleY,scaleZ, localPosX,localPosY,localPosZ} — pos, rot world; scale, localPos local; omitted axes kept |
gameobject_find {name, useRegex, component} · gameobject_get_info {name} |
gameobject_rename {name, newName} · gameobject_duplicate {name} |
gameobject_set_parent {childName, parentName} · gameobject_set_active {name, active} |
gameobject_delete {name} (dryRun first) |
component_add {name, componentType} |
component_set_property {name, componentType, propertyName, value} — vectors, colours "1,2,3"; references referenceName/referencePath/assetPath |
component_get_properties {name, componentType} |
material_assign {name, materialPath} |
light_set_properties {name, r,g,b, intensity, range, spotAngle, shadows} |
script_create {scriptName, folder, content} — full source; dryRun first; wait below |
scene_save {} (dryRun first) |
Everything else: one discovery call
GET /skills/recommend?intent=<words>&includeSchema=true&topN=3&wire=v2 → top 3 skills with exact schemas (~1–4 KB); several needs → one more &intent=<words> each, same call. Name known → GET /skills/schema?names=a,b&wire=v2. Wider layers, v2 fields, constants → discovery.
Execute
Several steps, one call: POST /skills/batch?expectProject=<project> {"steps":[{"skill":"gameobject_create","args":{"name":"Rig"}},{"skill":"gameobject_create","args":{"name":"Arm","parentName":"Rig"}}]} — ≤50 steps; a step may name objects earlier steps created, or use {"$ref":"$0.instanceId"}; the first failure skips the rest unless continueOnError:true; ?mode=transactional = all-or-nothing → batch.
dryRun. If this table, recommend or schema gave you the signature this session, execute directly: a failed validation runs nothing and returns the dryRun report (all validation buckets, parameter list). DryRun first (?mode=dryRun&wire=v2) for deletes, riskLevel high, mayTriggerReload/mayEnterPlayMode, approval mode, non-transactional multi-step batches, or when unsure; under a dryRunPolicy, execute with the returned ?dryRunToken=. valid:true = no validation errors (warnings never block; the target may still be missing); authorization previews the permission gate.
Never invent skill or parameter names: use this table, recommend or schema. On failure read suggestedFixes; open a module doc only when a response names one.

Verify from the read-back
A successful write returns the state read back from the Editor (e.g. world position, valueSet) — that is the verification; resolutionNotes flags a non-exact name match. Use *_get_info only for async results or missing fields. Script writes, and asset_refresh after you write a .cs yourself (compileTriggered:true), return waitUrl: one GET waits out compile+reload → status:"completed", or failed with errors in resultData.compilation. One command:
u=http://localhost:<port>; c="$u/skill/script_create?expectProject=<project>"; b='{"scriptName":"Spin","content":"<source>"}'; s='{"steps":[{"skill":"component_add","args":{"name":"Crate","componentType":"Spin"}},{"skill":"component_set_property","args":{"name":"Crate","componentType":"Spin","propertyName":"speed","value":"9"}}]}'; curl -s "$c&mode=dryRun" -d "$b" | grep -q '"valid":true' && J=$(curl -s "$c" -d "$b" | tee /dev/stderr | grep -o '/jobs/[^"]*=90') && curl -s --retry 20 --retry-connrefused --retry-all-errors --retry-delay 2 "$u$J" && curl -s "$u/skills/batch?expectProject=<project>" -d "$s"
Surface profile and errors
surfaceProfile is the user's panel choice; guide and noSceneAuthoring hide some writes, which answer SURFACE_EXCLUDED naming the doc to read or the profile to leave. It is a boundary: do the rest of the task, never retry or route around it (profiles).
| Code | Meaning → action |
|---|---|
MISSING_PARAM / TARGET_NOT_FOUND | Bad or unresolvable arguments → fix from details / locate the target (gameobject_find). |
INSTANCE_MISMATCH (409) | Resend to the port suggestedFixes name. |
MISSING_PACKAGE | Tell the user (dryRun missingPackages, recommend unavailable show it early); installing is their call. |
MODE_RESTRICTED / MODE_FORBIDDEN | Grant / bypass or Allowlist → operating mode. |
| other | error codes |
Compile status, events, analytics → observability; closed Editor + opt-in Unity CLI → unity-cli.
Current snapshot: 805 REST skills, 56 source files, 54 categories, 82 module doc directories (54 REST/module docs + 28 advisory docs), Unity 2022.3+, default timeout 15 minutes.
