Lead: the .sbproj field you changed that did nothing, the .config that did nothing, the clean build still running yesterday's code. Then two labelled halves.

The MCP Server. Eighteen tools, grouped ask-the-live-engine (8), ask-the-editor (6), change-something (4). The six ways an edit disappears table. 127.0.0.1:7269, loopback, and the claude mcp add --transport http sbox line. The one that reads as a bug and is not: the tools never appear in a client's tool list, reach them via search_tools and call_tool.

The AI Agent Skill. 17 reference files, the router explanation, the Unity translation table, 14_VERIFICATION as the file that matters most, and the four prompt patterns. Say plainly that the skill is not inside the package, because a library ships code rather than documentation, and give the clone and /plugin install routes.

Close on status (engine 26.08.05, both nullable configurations, 14 of 18 tools called live), MIT, and the three links: the repo, fobiat.dev/blog/p/sbox-skill, fobiat.dev.
