ucp-ui-toolkit from mflrevan/unity-control-protocol is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add mflrevan/unity-control-protocol/ucp-ui-toolkit@v0.7.1

Pins v0.7.1 in mdr.lock. Pin the fingerprint instead.

Author and verify Unity UI Toolkit interfaces (UXML, USS, TSS) with `ucp ui`: discover documents and scenarios, lint with Unity's own importers, instantiate a document in an isolated editor panel, inspect its resolved layout and bindings, populate lists and repeaters from JSON scenarios, and capture deterministic PNGs. Use after editing UXML/USS or when the user wants a UI checked or screenshotted without loading a scene. Requires Unity 6 or newer.

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

# UI Toolkit authoring loop

The loop is: edit UXML/USS on disk, `lint` (fast importer and schema pass), `inspect` (resolved
tree, layout, bindings), `screenshot` (visual evidence), `check` (all of it across every state,
with cleanup). Nothing here loads or dirties a scene; the harness opens a transient editor panel,
renders, and closes it.

## Discover

```bash
ucp ui list --root Assets/UI
ucp ui list --include-packages --limit 50 --json
```

Lists `.uxml` documents and `.ucp-ui.json` scenarios. Invalid scenarios stay in the list with
`valid: false` and a diagnostic, so discovery works while you are still authoring one.

## Lint

```bash
ucp ui lint Assets/UI
ucp ui lint Assets/UI/Inventory.uxml Assets/UI/Inventory.uss
ucp ui lint Assets/UI/Inventory.ucp-ui.json --fail-on-warnings --max-diagnostics 200
```

Runs Unity's synchronous UXML, USS, and TSS importers, reads their logs and flags, follows
dependencies, and clone-instantiates each document under a scoped log capture, which is what
catches an unknown element that imports cleanly and only fails when instantiated. Errors fail the
command; warnings fail it only with `--fail-on-warnings`. Diagnostics carry the asset path and
…

How to install

The exact contents, by fingerprint
mdr add mflrevan/unity-control-protocol/ucp-ui-toolkit@sha256:8991245f9b8762e2

The line at the top of this page pins the label v0.7.1, 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.
