datnt-cell Unity Tweening
Part of the Unity Skills plugin.
Unity Skills protocol (quick reference)
This plugin talks to the Unity Editor through a local REST server. Before the first skill call in a session:
GET /health— discover the server (it binds a port in8090–8100). ReadcurrentMode("approval"/"auto"/"bypass") andsurfaceProfile(full/guide/noSceneAuthoring) — confirmprojectNamematches the project you're editing.- Under
approvalmode, the first write to aFullAutoskill returnsMODE_RESTRICTEDand needs a user grant; underauto/bypasswrites execute directly.
dryRun gate: before executing any skill whose exact parameters you don't already hold, call POST /skill/<name>?mode=dryRun and iterate until the response says valid:true — never guess parameters from a skill name alone. Then execute the same call without ?mode=dryRun.
Batch execution: when touching 2+ objects, prefer POST /skills/batch ({"steps":[{"skill","args"}],"continueOnError":false}, up to 50 steps per call, also supports ?mode=dryRun) over repeated single-item calls.
Error codes:
| Code | Meaning |
|---|---|
MODE_RESTRICTED / MODE_FORBIDDEN |
Needs a user grant, or needs Bypass/Allowlist. |
SURFACE_EXCLUDED |
Hidden by the current surfaceProfile — a configuration boundary, not a failure; don't retry or route around it. |
MISSING_PARAM / TARGET_NOT_FOUND |
Bad or unresolvable arguments — dryRun for the schema, locate the target first. |
For the full protocol detail, error code catalog, and guide-mode manual-* docs, optionally install the unity-core plugin — it's not required, this summary covers what you need for this skill.

Routing
Skills are named <module>_<verb> (e.g. dotween_add_animation, primetween_generate_sequence). DOTween and PrimeTween are alternative tweening libraries — check which one the project has installed before picking a module. Always read the matching *-design doc before generating tween code: these are source-anchored to exact package versions and catalog lifetime/cancellation pitfalls (e.g. tweens outliving destroyed GameObjects) that the REST schema won't warn about. For pure async/await without tweening, read unitask-design.
Open the matching module doc before calling any skill whose exact parameters you don't already hold — dryRun first.
