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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is fully covered. The description adds real context by naming the source site, the Hebrew language, and the returned fields (slug, title, URL), but says nothing about ordering, result caps, or what an empty result means.

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 that carries purpose, scope, return fields, and the optional filter with no filler. Nothing could be removed without losing information.

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 correctly enumerates the returned fields, which is exactly what an agent needs. The only shortfall is the absence of ordering/pagination expectations for a list endpoint, a minor gap for a small, closed-world guide index.

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 coverage is 100%, so baseline would be 3, but the description adds substring-match semantics ("title contains a search term") where the schema only says "matched against guide titles". It also confirms the filter scope is titles only, not body text — a meaningful clarification for an agent choosing a query value.

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 and resource ("List the travel insurance guides published on checko.co.il") and even names the returned fields. It doesn't explicitly distinguish itself from the siblings get_guide and get_faq, though the plural 'list' vs. singular 'get' makes the split inferable.

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 word "optionally" implies the search term is a filter rather than a requirement, which is useful, but there is no explicit statement of when to call this versus get_guide for a single guide or get_faq. Usage is implied, not spelled out.

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