get_travel_timing_advice

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

Annotations already declare read-only, destructive=false, idempotent. Description adds value: 'FREE', 'no account setup, no external booking link, no booking side effects' which are beyond annotations.

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: first states purpose and examples, second gives usage and side-effect info. No redundant words, front-loaded.

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?

No output schema, but description gives reasonable context for a free advice tool. Could mention result format but not missing critical info for selection.

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% with descriptions for both parameters. Description does not add parameter-specific guidance beyond schema, meeting baseline 3.

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 provides 'practical travel timing advice' with specific examples (booking windows, airport arrival etc.) and distinguishes from sibling tool 'plan_flight_route'.

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?

Explicitly says 'Use for questions like when to book or how early to arrive' and 'use plan_flight_route when the traveler wants route planning', providing clear when-to-use and alternatives.

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