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

Annotations already establish that this is read-only, idempotent, and non-destructive, so the description does not need to restate safety. It adds modest context by noting that results include slugs and links, but it does not disclose matching semantics, case sensitivity, or pagination behavior. This is acceptable given the existing annotations.

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 sentences, no filler. The first sentence front-loads the search action, entity types, and geographic coverage; the second states the return payload. Every sentence earns its place.

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 low-complexity search tool with a full input schema, output schema, and rich annotations, the description covers the essential details: what is searched, where, and what comes back. It could mention result ordering or pagination, but those are minor gaps given the structured metadata already present.

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%, with all three parameters (query, limit, offset) already explained. The description's 'by name' phrase adds nothing beyond the query parameter's schema description, 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 clearly identifies the verb ('Search'), the resource (licensed insurers, reinsurers, takaful operators, groups) and the geographic scope, and states what is returned. It does not explicitly contrast itself with sibling list/get tools, but the 'by name' matching language makes the core purpose unambiguous.

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 use case is implied: use this when you want to find insurers, countries, or groups by name. However, there is no explicit guidance about when to prefer this over sibling tools like list_insurers, list_groups, or get_insurer, and no when-not-to-use conditions.

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