Each tool targets a distinct, non-overlapping purpose: two lookup helpers for separate dimensions (styles vs. rooms) and one action tool that composes them. There is no realistic way to confuse them, and the descriptions explicitly cross-reference each other to reinforce the intended workflow.

All three tools use a clean snake_case verb_noun pattern: list_design_styles, list_room_types, and design_a_room. The two listing tools are perfectly parallel, and the action tool follows the same verb-first convention.

Three tools is reasonable for a narrowly scoped link-generation flow: two enumeration helpers plus one generator. It sits at the lean end of appropriate, but each tool clearly earns its place with no redundancy.

The surface covers the core flow of discovering valid styles/rooms and producing a pre-configured design link. Minor gaps exist (e.g. no way to check the status or result of a generated design, or fetch account history), but these fall outside the intended handoff where the user completes the workflow externally.
