What you get
- 839 REST skills across 54 categories, with batch operations
- 29 advisory design modules (architecture, performance, patterns and more)
- Approval / Auto / Bypass permission modes and a JSONL audit log
- Dry-run and plan modes, per-task undo and transactional batches that roll back on failure

Good fit
- Letting Claude Code, Codex or Cursor edit scenes, prefabs and components in the open Unity Editor
- Teams that want an approval step and an audit trail for agent edits
Not for
- Unity versions older than 2022.3: some 2021 code remains, but it is no longer tested
Overview
UnitySkills is one of the larger community unity skills packs. A Unity package runs a REST server inside the Editor, and a set of Agent Skills shows your coding agent how to call it. The agent can then create GameObjects, change components, materials, lighting, Cinemachine, NavMesh and more in the open project, instead of editing scene YAML on disk.
Most of the repository is about safety. New installs start in Auto mode, which blocks high-risk operations. ?mode=dryRun and ?mode=plan check a call and estimate its effect without writing anything. Every call is logged to Library/UnitySkillsAudit.jsonl, and workflow_undo_task rolls back a single task.
Compared with other Unity options
- MCP for Unity (CoplayDev) is the MCP bridge UnitySkills started from. Pick it if your client only speaks MCP.
- Unity official skills are workflow prompts without an Editor bridge, so they can be used alongside this pack.
Requirements
- Unity 2022.3 or newer (the maintained baseline, including Unity 6)
- An agent that reads SKILL.md folders
