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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds the useful constraint that booking/payment are out of scope and happen externally. However, pagination behavior and result count per page are only in the schema, not the description, so it doesn't go beyond the baseline.

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?

Front-loads the core capability and country scope, then states the booking boundary. It is a bit repetitive because the Arabic sentence mirrors the English, roughly doubling length, but each sentence carries meaning and nothing is padded.

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 listed hotel search with a fully documented schema and no output schema, the definition covers scope, geography, and the booking boundary an agent needs. It lacks only a note on pagination limits or result ordering, which keeps it from a 5.

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%, so every parameter is already documented, including the city/query distinction and the 10-per-page pagination. The description duplicates the country list in prose but adds no syntax or format detail beyond the schema. Baseline 3 is appropriate.

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 (search) and resource (hotels) with rich scope: 20,000+ hotels, seven countries, and the attributes surfaced (stars, review score, starting price). It doesn't explicitly distinguish itself from sibling search_restaurants or compare_prices, so it stops short of a 5.

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?

Implied usage is search-by-city-or-name, and the 'booking and payment happen on mosaiden.com' sentence clarifies the boundary of what the tool does. But it never states when to prefer this over compare_prices or search_souq, so usage is left to inference.

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