Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

TDQS
Scored across 6 tools
Each tool maps to a distinct stage in the diagram lifecycle: create, layout, update, validate, export, and capability discovery. The boundaries between create and layout are clarified by their descriptions, so an agent can reliably choose the right operation.
All tool names use the same sketchwright_ prefix followed by a consistent verb_noun pattern in snake_case. There are no mixed conventions or vague standalone verbs.
Six tools is well-scoped for a diagram generation server, covering creation, layout, updating, validation, export, and discovery without redundancy. Each tool has a clear, non-overlapping role.
The surface covers the core diagram lifecycle from specification creation through validation and export, including incremental updates and capability discovery. Minor gaps exist around persisted diagram management (e.g., listing or deleting saved diagrams), but these are not essential for the stated purpose.
