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

Annotations already declare readOnlyHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds only that exactly one record is returned; it says nothing about not-found behavior, permissions, or whether ids are global or per-collection.

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?

A single front-loaded sentence with no padding or redundancy. It is efficient, though it is so terse that it sacrifices useful detail rather than earning brevity through completeness.

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 two-parameter read tool with full schema coverage and annotation-declared safety, the description is minimally sufficient. It omits what the returned record contains and what happens when an id does not exist in the given collection, which would matter for error handling.

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?

Schema description coverage is 100% and the resource enum is fully enumerated in the schema, so the baseline is 3. The description restates 'by resource and id' without adding format, case sensitivity, or id-acquisition guidance beyond the structured fields.

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 (fetch) and resource (a single SuperhotGeo record) and implicitly contrasts with the listing sibling by saying 'a single' record. It does not explicitly name list_resource or search, so an agent must infer the boundary rather than being told it.

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?

It states the retrieval is keyed by resource and id, but never says when to pick this over list_resource, search, or fetch, nor any prerequisite such as needing a known id. Usage is only inferable from the phrase 'a single record'.

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