calculate_trip_budget

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

With no annotations provided, the description bears full responsibility for disclosing behavioral traits. It only states 'Calculate total estimated budget' without indicating side effects, required permissions, or whether it is a read-only operation. No mention of data sources or accuracy.

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 a single, concise sentence that immediately communicates the tool's purpose. It is efficient with no wasted words. Could be slightly more informative while maintaining brevity.

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?

The description fails to explain what the output looks like, as there is no output schema. It does not specify whether the budget includes breakdowns, currency, or assumptions. For a tool that computes a value, this is a significant gap.

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?

All four parameters are described in the input schema (100% coverage). The description adds no additional meaning beyond what the schema provides. It does not clarify relationships between parameters or provide examples of valid inputs.

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 clearly states the tool's function: calculating a total estimated budget for a trip. It is distinct from sibling tools (exchange rate, weather, accommodation, flights) which cover different aspects of trip planning. However, it could be more specific about what factors into the budget (e.g., based on destinations, duration, budget level).

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?

No explicit guidance on when to use this tool versus siblings. However, the sibling tools are clearly in different domains (exchange rates, weather, accommodation, flights), so usage context is implied. The description lacks when-not or alternative recommendations.

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