What it does

Unity Skills Index is an agent skill from Besty0728/Unity-Skills. Index of all Unity Skills modules with per-module mode labels (SA/FA/Mixed). Use to find which module covers a task before loading its doc.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `sample/SKILL.md` and `test/SKILL.md`).

It sits in Game Development. The repository describes itself as: AI automation skills specifically designed for Unity. The licence is MIT.

When your agent uses it

  • Find which module covers a task before loading its doc

Example prompts

  • “/unity-skills-index”

What it can do on your machine

Read from SKILL.md and the folder at commit 6ec5de2. 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

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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.

Context cost

Unity Skills Index loads about 2.8k tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 924 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~40
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

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); files beside SKILL.md are not scanned.

Unity Skills - Module Index

Module docs. Start with ../SKILL.md for mode switching and schema-first rules.

Multi-instance: For version-specific projects, call unity_skills.set_unity_version(...) first. Schema-first: Exact signatures come from the root quick reference, from GET /skills/recommend?intent=<words>&includeSchema=true&topN=3&wire=v2 (unity_skills.find_skills(intent, top_n=3, include_schema=True, wire="v2")), or from GET /skills/schema?names=a,b&wire=v2 when the name is known; the full GET /skills/schema (unity_skills.get_skill_schema()) is ~707 KB. Load module docs for workflow guidance and guardrails. Split modules: gameobject, component, batch and script keep their shared rules and skill list in SKILL.md and each skill's parameter table, item fields and return shape in reference/<skill_name>.md (one small file per skill), rarely needed once the schema's parameter notes are in hand.

Modules

Mode legend (v1.9.0+, caller-facing — describes what the caller can do, not the C# attribute):

  • SA — module skills mostly run directly in all three modes (Approval / Auto / Bypass) without a grant.
  • FA — module skills mostly require user grant under Approval (single-shot one-step execution); under Auto / Bypass they run directly with audit only.
  • Mixed — module is split between SA and FA; check per-skill mode before calling (GET /skills?full=1, or the scoped GET /skills/schema?category=<Category> — bare GET /skills is the brief directory and carries no mode).
  • Suffix * — module contains auto-forbidden skills (Delete / Play Mode / Domain Reload / high-risk). These return MODE_FORBIDDEN under Approval and Auto; only Bypass runs them, or the user can permanently allow them via the Allowlist. Never attempt grant for them.

Labels are guidance only; the per-skill mode field (GET /skills?full=1 / GET /skills/schema?category=<Category>) is authoritative.

Batch-First Rule

When a task touches 2+ objects in Auto / Bypass mode (or after a successful grant under Approval), prefer *_batch skills over repeated single-item calls.

Skill Naming Convention

Skills follow <module>_<action> or <module>_<action>_batch. Use schema to verify the exact prefix list. Special: scene_analyze, hierarchy_describe, project_stack_detect → perception; job_* → batch. If a skill name does not match a valid prefix or a schema result, do not invent it.
