unity-cli-loop: Skill for Claude Code

.agents/skills/uloop-launch/SKILL.md

uloop-launch is a skill for Claude Code, Codex from hatayama/unity-cli-loop. It costs 46 tokens per session (814 once invoked), scanned A, original, MIT.

A command for opening or restarting the Unity Editor with the correct version for a project. Unity Editor is the application used to build and run Unity games.

In plain words
What is it for?
Launching a project, restarting a running Unity Editor, selecting a build platform, or adding a project to Unity Hub without launching it.
Why use it?
It removes the manual work of finding the project, choosing its Unity version, and waiting for the editor to become ready for commands.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is hatayama/unity-cli-loop's own configuration. It tells Claude Code and Codex how to work on unity-cli-loop itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything unity-cli-loop configures →

Token cost

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.

Security

Grade A, and why

uloop-launch 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 yesterday.

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.

uloop launch

Launch Unity Editor with the correct version for a project.

uloop launch is not fire-and-forget. When Unity needs to start or restart, the command waits until Unity is actually ready for CLI operations before it exits.

Usage

uloop launch [project-path] [options]

Parameters

Parameter Type Description
project-path string Optional. Use only when the target Unity project is not in the current directory.
-r, --restart flag Quit running Unity and restart
-q, --quit flag Quit an existing Unity process for the project without launching
--editor-version <version> string Use this Unity Editor version instead of ProjectVersion.txt
-p, --platform <P> string Build target (e.g., StandaloneOSX, Android, iOS)
--max-depth <N> number Search depth when project-path is omitted (default: 3, -1 for unlimited)

Output

May print status/progress lines before the final JSON payload, such as project path, detected Unity version, or readiness wait messages.

The final JSON payload includes:

  • Success: whether the command completed
  • Ready: whether Unity CLI Loop is ready for commands
  • ServerReady: whether the Unity CLI Loop server accepted requests
  • ProjectIpcReady: whether the project IPC path accepted tool requests
  • AlreadyRunning: whether an existing Unity process was reused
  • Launched: whether this command launched a Unity process
  • Restarted: whether this command stopped an existing process and launched a new one
  • Quit: whether this command stopped Unity without launching a new process
  • PreviousProcessId: process ID stopped by restart or quit, when available
  • StopMethod: how restart or quit stopped that process, omitted when there was none — Quit when Unity exited on request, ForceKill when it had to be killed
  • CurrentProcessId: current Unity process ID, when available
  • ProjectRoot: resolved project root
  • Message: readiness summary

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.
