unity-cli-loop: Skill for Claude Code

.agents/skills/uloop-replay-input/SKILL.md

uloop-replay-input is a skill for Claude Code, Codex from hatayama/unity-cli-loop. It costs 33 tokens per session (566 once invoked), scanned A, original, MIT.

A Unity PlayMode tool that reads a JSON recording and injects the same keyboard and mouse actions frame by frame. PlayMode is Unity's mode for running a game inside the editor.

In plain words
What is it for?
Starting, stopping, checking, and looping recorded input sequences, either from the newest recording or from a specified JSON file.
Why use it?
It makes gameplay reproduction, end-to-end testing, and demos repeatable instead of relying on manual input. Identical results still require the game itself to behave deterministically.

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-replay-input 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 1mo ago.

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 replay-input

Replay recorded keyboard and mouse input during PlayMode. Loads a JSON recording and injects input frame-by-frame via Input System with zero CLI overhead. Supports looping and progress monitoring.

Create recording JSON files in the Unity Editor from Window > Unity CLI Loop > Recordings with Start Recording and Stop Recording. There is no CLI command for recording input.

Usage

# Start replay (auto-detect latest recording)
uloop replay-input --action start

# Start replay with specific file
uloop replay-input --action start --input-path scripts/my-play.json

# Start replay with looping
uloop replay-input --action start --loop

# Check replay progress
uloop replay-input --action status

# Stop replay
uloop replay-input --action stop

Parameters

Parameter Type Default Description
--action enum start start - begin replaying, stop - stop mid-way, status - check progress
--input-path string auto Path to the recording JSON. When empty, auto-detects the latest recording in .uloop/outputs/InputRecordings/
--no-show-overlay flag - Hide replay progress overlay
--loop flag - Loop continuously

Deterministic Replay

Replay injects the exact same input frame-by-frame, but the game must also be deterministic to produce identical results. If replay output must be compared across runs, read references/deterministic-replay.md before interpreting failures.

Prerequisites

  • Unity must be in PlayMode
  • Input System package (com.unity.inputsystem) must be installed; this tool only works with the New Input System.

Output

Returns JSON with:

  • Success: Whether the operation succeeded
  • Message: Status message
  • Action: Echoes which action was executed (start, stop, or status)
  • InputPath: Path to recording file (nullable string; populated on start only)
  • CurrentFrame: Current replay frame index (nullable int)
  • TotalFrames: Total frames in the recording (nullable int)
  • Progress: Replay progress (nullable float in 0.0 – 1.0)
  • IsReplaying: Whether replay is currently active (nullable bool)

What this file has done since we first saw it

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.
