uloop-focus-window

A command that brings the main Unity Editor window to the front of the screen, optionally for a specific project.

In plain words

Use it to focus the correct Unity project window, especially before capturing the Unity window or interacting with it.
Why use it?
It makes sure Unity is visible before visual checks or actions that depend on the editor window, even while Unity is busy.

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-focus-window 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 yesterday.

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.

Usage

uloop focus-window

Output

Returns JSON with:

  • Success: Whether the focus operation succeeded
  • Message: Status message (e.g. Unity Editor window focused (PID: 12345), or the failure reason such as Unity project not found / No running Unity process found for this project / Failed to focus Unity window: <reason>)

Notes

  • Useful before uloop screenshot to ensure the target window is visible
Changes

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.
