Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered and the description is consistent with it. The description adds genuine value beyond the annotations by describing what each returned item contains (template_id, 3D view, PDF drawings, editable copy). It does not mention pagination or result-size limits, which is a minor gap for a listing tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences with no filler. The resource and its scope are front-loaded, and the second sentence delivers the only non-obvious detail (template_id linkage and per-plan artifacts).

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only listing tool with full schema coverage, annotations, and confirmed no output schema, the description is nearly complete: it explains what is listed and what each item provides. What is missing is minor — result volume/pagination behavior and how the optional user_request affects output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There is a single optional parameter and the schema description coverage is 100%, so the schema fully documents user_request. The description adds no meaning about how that free-text request influences filtering or ranking, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb and resource ("Lists the ready-made wooden house plans on Geoniks") and enumerates the catalog content (cabins, cottages, family houses) plus returned attributes (size, floors, rooms). It implicitly separates itself from creation-oriented siblings like design_wooden_house and design_from_floor_plan, but never names an alternative explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage context is only implied: the mention that each plan carries a template_id for starting a design hints that this is a discovery step before design_wooden_house or design_from_floor_plan. There is no explicit when-to-use, when-not-to-use, or alternative routing statement, so the agent must infer the workflow.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
