What it does

Uloop Screenshot is an agent skill from kurotu/VRCQuestTools. Capture Unity Editor windows or Game View rendering as PNG. Use for visual checks, debugging, documentation, or annotated UI element coordinates.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/annotated-elements.md`).

It sits in Development. It works with 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

  • Annotated UI element coordinates

Example prompts

  • “/uloop-screenshot”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit f55dbd5. 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 Screenshot loads about 1.2k tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 377 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

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.

Usage

bash
npx --yes uloop-cli@2.2.0 screenshot [--window-name <name>] [--resolution-scale <scale>] [--match-mode <mode>] [--capture-mode <mode>] [--annotate-elements] [--elements-only] [--output-directory <path>]

Parameters

ParameterTypeDefaultDescription
--window-namestringGameWindow name to capture. Ignored when --capture-mode rendering.
--resolution-scalenumber1.0Resolution scale (0.1 to 1.0)
--match-modeenumexactWindow name matching mode: exact, prefix, or contains. Ignored when --capture-mode rendering.
--capture-modeenumwindowwindow=capture EditorWindow including toolbar, rendering=capture game rendering only (PlayMode required, coordinates match simulate-mouse)
--output-directorystring""Output directory path for saving screenshots. When empty, uses default path (.uloop/outputs/Screenshots/). Accepts absolute paths.
--annotate-elementsbooleanfalseAnnotate interactive UI elements with index labels and interaction hints (A / CLICK, B / DRAG, ...). Only works with --capture-mode rendering in PlayMode.
--elements-onlybooleanfalseReturn only annotated element JSON without capturing a screenshot image. Requires --annotate-elements and --capture-mode rendering in PlayMode.

Match Modes

ModeDescriptionExample

prefixWindow name must start with the input"Project" matches "Project" and "Project Settings"
containsWindow name must contain the input anywhere"set" matches "Project Settings"

Examples

bash
# Take a screenshot of Game View (default)
npx --yes uloop-cli@2.2.0 screenshot

# Capture game rendering (coordinates match simulate-mouse, PlayMode required)
npx --yes uloop-cli@2.2.0 screenshot --capture-mode rendering

# Annotate interactive UI elements with index labels (for simulate-mouse workflow)
npx --yes uloop-cli@2.2.0 screenshot --capture-mode rendering --annotate-elements

# Get UI element coordinates without capturing an image (fastest)
npx --yes uloop-cli@2.2.0 screenshot --capture-mode rendering --annotate-elements --elements-only

# Take a screenshot of Scene View
npx --yes uloop-cli@2.2.0 screenshot --window-name Scene

# Capture all windows starting with "Project" (prefix match)
npx --yes uloop-cli@2.2.0 screenshot --window-name Project --match-mode prefix

# Save screenshot to a specific directory
npx --yes uloop-cli@2.2.0 screenshot --output-directory /tmp/screenshots

# Combine options
npx --yes uloop-cli@2.2.0 screenshot --window-name Scene --resolution-scale 0.5 --output-directory /tmp/screenshots

Output

Returns JSON with:

  • ScreenshotCount: Number of windows captured
  • Screenshots: Array of screenshot info, each containing:
    • ImagePath: Absolute path to the saved PNG file. Empty when --elements-only is used because no image file is written.
    • FileSizeBytes: Size of the saved file in bytes
    • Width: Captured image width in pixels
    • Height: Captured image height in pixels
    • CoordinateSystem: "gameView" or "window"
    • ResolutionScale: Resolution scale used for capture
    • YOffset: Y offset used for gameView coordinate conversion
    • AnnotatedElements: Array of annotated UI element metadata. Empty unless --annotate-elements is used.

For AnnotatedElements fields and gameView coordinate conversion, read references/annotated-elements.md before using screenshot coordinates with mouse simulation tools.

When multiple windows match (e.g., multiple Inspector windows or when using contains mode), all matching windows are captured with numbered filenames (e.g., Inspector_1_*.png, Inspector_2_*.png).

Notes

  • Use npx --yes uloop-cli@2.2.0 focus-window first if needed
  • Target window must be open in Unity Editor
  • Window name matching is always case-insensitive
