B3/5.0
Behavior4/5

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

It goes beyond the annotations (readOnly/idempotent/openWorld=false) by disclosing the commercial behavior: $0.15 per call, a free preview_capability path, x402 payment, and that an unpaid MCP call returns payment instructions instead of results. That is genuinely useful context an agent needs before calling. It stops short of describing result shape or rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The 'When' and 'Selection' fragments are duplicated boilerplate that conveys nothing, and 'see the schema' spends words without adding information. The remaining content (purpose, pricing, preview path) is front-loaded but buried among filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained, and the payment/preview flow is covered. However, for a 13-parameter paid comparison tool with a nested preferences object, the near-absent parameter guidance and the missing relationship to flight_search leave the agent under-equipped to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 8% across 13 parameters, so the description must compensate and largely does not. It gestures at the four comparison dimensions (price/duration/stops/reliability) implicitly matching the nested preferences weights, but never explains origin, dates, currency, cabinClass, adults/children, or the preference weighting model, only deferring with 'see the schema'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The opening sentence gives a specific verb (compare) and resource (current flight offers) plus the comparison dimensions: price, duration, stops and reliability signals. It is distinguishable from generic siblings, though it never names flight_search or trip_cost_estimate, which is where an agent would most plausibly look first.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'When' clause is circular: 'Use when an agent needs flight compare from current travel offers' restates the tool name rather than naming a real trigger. The 'Selection: supporting' line then repeats the same sentence verbatim, offering no condition under which this beats flight_search.

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