unity-driving from citiesskylinesmodding/agents-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Driving a live Unity Mono development build with the unity MCP tools. Load before first use of any unity tool, when planning multi-step live state edits, or when a unity tool call fails or returns puzzling results.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Driving a Unity game over SDB The `unity` tools drive a running Unity Mono development build over the Mono Soft Debugger protocol (SDB); this skill is the procedure the tool schemas cannot carry. Everything holds for any dev-Mono Unity game; the type names in examples are placeholders (`MyGame.…`), so substitute the target's own. A retail build exposes no SDB port; only a development Mono build is drivable. ## Session lifecycle The first tool that needs the VM attaches on its own, the session persists, and a dropped connection reattaches on the next call, so just call the tool you need. The game is found by the PlayerConnection beacon it multicasts, which carries the debugger endpoint: there is nothing to configure, and every attach resolves that endpoint afresh, so a game restart costs nothing. `status` is the read-only orient step: what the beacon advertises, the endpoint an attach would use, whether another client on this machine holds that endpoint's slot (`slotHeld`), and session state (attached, held suspensions). Everything it reports describes the present, so act on it as read. …

How to install
mdr add citiesskylinesmodding/agents-plugins/unity-driving@sha256:57c2a59a2d9ffb15The line at the top of this page pins the label git:20261020.cf97321, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
