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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds a useful behavioral note about what comes back (property ids and listing links), but says nothing about pagination limits, rate behavior, or result ordering despite exposing page/limit params.

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 efficient sentence with the resource front-loaded and the return payload briefly noted. No padding, though the colon construction packs two distinct ideas into one clause.

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 an output schema present and 100% parameter coverage, the description only needs to frame purpose and payload, which it does. The gap is routing guidance against the many sibling lodging searches, not missing field or return detail.

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 all four parameters are fully documented in structured data. The description restates the 'numeric Agoda city id' concept but adds no syntax, format, or precedence detail beyond what the schema already supplies. Baseline 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?

States a specific verb and resource (hotel search by city) and goes further by describing the output shape: matching property ids plus a direct listing link. Clear enough to distinguish from agoda_hotel_detail, but it never names or contrasts with its siblings explicitly.

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 phrase 'by city' implies the usage context (city-scoped discovery) but the description never states when to prefer this over agoda_hotel_detail, agoda_homes_search, or other lodging searches, nor does it give exclusions. Usage is only inferable.

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