tool_find_destinations_by_budget

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

No annotations are provided, so the description carries the full burden. It discloses that it calculates flight+hotel costs and ranks destinations, but does not mention any behavioral traits like data freshness, caching, failure modes, or required permissions.

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?

The description is concise with a one-line purpose, an inspiration example, and a parameter list. No wasted sentences, though the parameter list is somewhat lengthy and could be formatted more cleanly.

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?

Given 10 parameters, no output schema, and no annotations, the description covers inputs well but omits the output format (e.g., what the ranking looks like) and any prerequisites or edge cases.

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 0%, but the tool description adds brief explanations for all 10 parameters (e.g., 'origin: Departure airport IATA code (e.g., "JFK")'), including examples. This compensates well for the lack of schema descriptions.

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 'Ranks destinations under a total budget with flight + hotel costs calculated', specifying the verb (ranks), resource (destinations), and constraint (budget). This clearly differentiates it from siblings like tool_cheap_anywhere_from or tool_score_destinations.

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 description gives an inspiration example ('I have $1500, where can I go?') implying when to use it, but does not explicitly state when not to use it or mention alternatives among the many sibling destination tools.

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