Record PlayMode keyboard and mouse input to JSON. An agent skill from kurotu/VRCQuestTools.

What it does

Uloop Record Input is an agent skill from kurotu/VRCQuestTools. Record PlayMode keyboard and mouse input to JSON. Use to capture gameplay, bug repro, or E2E input sequences for replay.

Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/deterministic-replay.md`).

It sits in Testing & QA, covering End-to-end testing. 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

  • Capture gameplay
  • E2E input sequences for replay

Example prompts

  • “/uloop-record-input”

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 Record Input loads about 605 tokens when it runs, and up to ~953 if it reads all its reference files. Until then it costs about 35 tokens; SKILL.md has 224 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~605
With references · SKILL.md plus every file in references/, read only if the agent opens them
~953

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.

description
Record PlayMode keyboard and mouse input to JSON. Use to capture gameplay, bug repro, or E2E input sequences for replay.

npx --yes uloop-cli@2.2.0 record-input

Record keyboard and mouse input during PlayMode frame-by-frame into a JSON file. Captures key presses, mouse movement, clicks, and scroll events via Input System device state diffing.

Usage

bash
# Start recording
npx --yes uloop-cli@2.2.0 record-input --action Start

# Start recording with key filter
npx --yes uloop-cli@2.2.0 record-input --action Start --keys "W,A,S,D,Space"

# Stop recording and save
npx --yes uloop-cli@2.2.0 record-input --action Stop

# Stop and save to specific path
npx --yes uloop-cli@2.2.0 record-input --action Stop --output-path scripts/my-play.json

Parameters

ParameterTypeDefaultDescription
--actionenumStartStart - begin recording, Stop - stop and save
--output-pathstringautoSave path. Auto-generates under .uloop/outputs/InputRecordings/
--keysstring""Comma-separated key filter. Empty = all common game keys

Deterministic Replay

Replay injects input frame-by-frame, so the game must also be deterministic to produce identical results. If the recording will be used for E2E tests, bug reproduction, or replay verification, read references/deterministic-replay.md before designing assertions or game logic.

Prerequisites

  • Unity must be in PlayMode
  • Input System package must be installed (com.unity.inputsystem)
  • Use this only when the project already uses the New Input System.

Output

The CLI prints JSON with:

  • Success: Whether the operation succeeded
  • Message: Status message
  • Action: Echoes which action was executed (Start or Stop)
  • OutputPath: Path to saved recording (nullable; populated on Stop only)
  • TotalFrames: Number of frames recorded (nullable int; populated on Stop only)
  • DurationSeconds: Recording duration in seconds (nullable float; populated on Stop only)

The CLI output contains only these six payload fields. Internal metadata such as Ver is removed before printing. There is no RecordingId, StartTimestamp, KeysCaptured, or per-frame data in the response — frame data lives only in the JSON file at OutputPath.
