What it does

Uloop Compile is an agent skill from kurotu/VRCQuestTools. Compile the Unity project and report errors/warnings. Use after C edits or when a full Domain Reload compile is needed.

Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Game Development. It works with C# and Unity. The repository describes itself as: Unity editor extension to support uploading VRChat avatars for Oculus Quest. The licence is MIT.

When your agent uses it

  • Game Development work in your project

Example prompts

  • “/uloop-compile”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit c68d147. 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

    Shell commands in SKILL.md call:

    • npx

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

  • Network

    No URLs in SKILL.md. Its commands use npx, 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.

Context cost

Uloop Compile loads about 535 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 150 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~535

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.

name
uloop-compile
description
Compile the Unity project and report errors/warnings. Use after C# edits or when a full Domain Reload compile is needed.

npx --yes uloop-cli@2.2.0 compile

Execute Unity project compilation.

Usage

bash
npx --yes uloop-cli@2.2.0 compile [--force-recompile] [--wait-for-domain-reload]

Parameters

ParameterTypeDefaultDescription
--force-recompilebooleanfalseForce full recompilation (triggers Domain Reload)
--wait-for-domain-reloadbooleanfalseWait until Domain Reload completes before returning

Global Options

OptionDescription
--project-path <path>Optional. Use only when the target Unity project is not the current directory.

Examples

bash
# Check compilation
npx --yes uloop-cli@2.2.0 compile

# Force full recompilation
npx --yes uloop-cli@2.2.0 compile --force-recompile

# Force recompilation and wait for Domain Reload completion
npx --yes uloop-cli@2.2.0 compile --force-recompile true --wait-for-domain-reload true

# Wait for Domain Reload completion even without force recompilation
npx --yes uloop-cli@2.2.0 compile --force-recompile false --wait-for-domain-reload true

Output

Returns JSON:

  • Success: boolean
  • ErrorCount: number
  • WarningCount: number

Troubleshooting

Diagnose the failure mode before retrying.

Stale lock files (CLI hangs or shows "Unity is busy" while Unity Editor is running):

bash
npx --yes uloop-cli@2.2.0 fix

This removes any leftover lock files (compiling.lock, domainreload.lock, serverstarting.lock) from the Unity project's Temp directory. Then retry npx --yes uloop-cli@2.2.0 compile.

Unity Editor not running (CLI returns a connection failure and no Unity process is alive):

bash
npx --yes uloop-cli@2.2.0 launch

npx --yes uloop-cli@2.2.0 launch auto-detects the project at the current working directory and opens it in the matching Unity Editor version. After Unity finishes launching, retry npx --yes uloop-cli@2.2.0 compile.
