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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds genuinely new behavioral context by disclosing the response shape ('title, link, summary and a few of their products'), which matters because there is no output schema.

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, front-loaded with the core action and scope, with no filler. The long parenthetical topic list is dense but earns its place by bounding the corpus; it could be trimmed slightly without loss.

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 read-only, two-parameter search with no output schema, the description covers domain, accepted languages, and return fields — everything needed to call it correctly. The only real omission is explicit disambiguation from get_guide and search_baby_products.

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 both parameters are already documented in the schema, including examples and the 1-10 range for max_results. The description only reinforces that the query may be Hebrew or English and implies results are limited to a subset of products; the baseline 3 applies when the schema carries the parameter detail.

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 states a specific verb and resource ('Find MamaChoice's Hebrew buying guides') and enumerates concrete topic areas (strollers, sleep, feeding, safety, travel), so the agent knows exactly what corpus is searched. It does not explicitly name or contrast with the siblings get_guide or search_baby_products, leaving the search-vs-fetch and guides-vs-products distinction to inference.

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 is only implied: the agent can infer this is the discovery tool and that get_guide is for fetching a known guide, but no when-to-use/when-not statement or sibling reference is given. The note that queries are accepted in Hebrew or English is useful input guidance but is not routing guidance.

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