Uloop Simulate Mouse Input

What it does

When your agent uses it

• Gameplay clicks
• Use simulate-mouse-ui for EventSystem UI elements

Example prompts

• “/uloop-simulate-mouse-input”

Requirements

• Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Ensure Unity is in PlayMode (use npx --yes uloop-cli@2.2.0 control-play-mode --action Play if not)
2. 2For Click/LongPress: determine the target screen position (use npx --yes uloop-cli@2.2.0 screenshot to find coordinates)
3. 3Execute the appropriate npx --yes uloop-cli@2.2.0 simulate-mouse-input command
4. 4Take a screenshot to verify the result: npx --yes uloop-cli@2.2.0 screenshot --capture-mode rendering
5. 5Report what happened

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 Simulate Mouse Input loads about 1.4k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 491 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~49

When it runs · the whole SKILL.md, loaded when a task matches

~1.4k

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

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.
