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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so safety and determinism are covered. The description adds that the catalog is 'curated' and 'public', implying a fixed, non-user-scoped dataset, but it says nothing about the 20-item cap or how results are ordered or paged.

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 filler or redundancy. It is slightly over-adjectived ('curated', 'stable', 'canonical'), but every clause still points at what is returned.

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?

With no output schema, the description must carry the return contract, and it does sketch the shape (service objects linked to canonical content). It is still silent on result count limits, ordering, and pagination behavior, which an agent needs to call this correctly given the capped limit parameter.

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 one parameter ('limit') with 0% schema description coverage; the schema supplies only type, default, maximum, and minimum with no prose. The description never mentions the limit, its cap of 20, or whether the catalog is paginated, so it does not compensate for the missing schema documentation.

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?

States a specific verb ('Return') and resource ('the curated public Oleba service catalog'), which an agent can distinguish from the singular sibling get_service. However, the trailing clause about 'stable machine-readable service objects linked to canonical public content' is marketing-flavored jargon that adds little definitional precision.

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?

The description gives no indication of when to call this tool versus get_service, search_site, or check_service_area, all of which operate on the same domain. There is no mention of prerequisites, when the catalog is appropriate, or when a more targeted sibling is preferable.

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