unity-implement

Implement the work described by the user in the spec or tasks.

1. Establish the boundary

• unity-cli.
• ui-ugui for Runtime/Canvas UI or ui-imgui for Editor IMGUI.
• no new external package, Packages/manifest.json change, or editor-resource import such as TMP Essentials.
• An open Editor.

On a failed gate, stop and report with the required user action.

2. Implement and validate

• Call the Skill tool with unity-tdd where possible, at pre-agreed seams.
• Follow test-protocol.md for every test run.
• Run typechecking regularly, single test files regularly, and the full test suite once at the end.
• Use unity-cli for every non-code edit; never edit Unity YAML directly.
• Use ui-ugui for Runtime/Canvas UI and ui-imgui for Editor IMGUI.
• Use repository-root .scratch/ for all temporary scripts, files, logs, exports, screenshots, and command output.
• Report human playtesting, Player Build, as deferred rather than running it.

3. Report

Once done, report the results or any issues encountered.
