Create Trip Share Link

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

Adds real context beyond annotations: the link is public and read-only, and the operation refreshes an existing link rather than duplicating it (consistent with idempotentHint=true). It also discloses the return value (the shareable URL), which matters since no output schema exists. It stops short of explaining revocation or expiry of the link, which is the only notable gap.

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?

Three short sentences, front-loaded with the action and its effect, then the return value, then the trigger condition. No filler.

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?

For a single-parameter, no-output-schema tool this covers purpose, trigger, and return value. It could say more about link lifetime/revocation, but nothing essential for correct invocation is missing.

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% and tripId is documented in the schema, so the description adds nothing parameter-specific beyond referring to 'the trip'. Baseline 3 is appropriate.

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+resource ('Create (or refresh) a public read-only link to the trip') and clarifies the effect (read-only, public). No sibling tool overlaps, and the refresh behavior is called out 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?

Gives clear triggering context: 'Use when the user asks to share, send or publish a trip.' No alternatives or exclusions are named, but none are needed since no sibling offers competing share functionality.

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