explain_travel_timing

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

Description states read-only, no authentication, no booking link, and no booking side effects. Annotations already indicate readOnlyHint and idempotentHint, but the description adds specific behavioral context 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 concise sentences with purpose, topics, usage guidance, and behavioral traits front-loaded. No unnecessary words.

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?

Covers purpose, usage, and behavior. Lacks explicit mention of output format (likely textual explanation), but given the tool name and description, it's largely complete. Optional params are noted, but their impact on output is implicit.

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 baseline 3. The description does not add additional semantic info beyond what the schema already provides for the two optional parameters.

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?

Description clearly states the tool explains general travel timing and logistics, listing specific topics. It distinguishes from sibling 'search_travel_options' by specifying when to use each.

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 advises using this tool for general timing advice (e.g., when to book, how early to arrive) and directs to 'search_travel_options' for route-specific search. Also notes read-only, no auth, no booking side effects.

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