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

With no annotations, the description must carry the full burden of explaining behavior, but it only hints at validation and cost. It does not state whether the tool performs a live search, whether it mutates any state, or what guarantees 'honest availability semantics' actually represent. Important behavioral traits like external calls, caching, and side effects are undisclosed.

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 short and front-loaded, with the core action in the first clause. The cost note is a useful addition. It earns its place without excessive verbosity, though the vague 'honest availability semantics' wording could be tightened.

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?

Given six untyped parameterswooden, no output schema, and no annotations, the description leaves major gaps: date formats, airport code format, cabin value constraints, passenger limits, and response shape. The mention of pricing helps, but it does not compensate for the missing operational context an agent needs to call this tool reliably.

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 0%, yet the description provides no parameter-level meaning beyond the word 'bounded.' It does not clarify date formats, airport code requirements, cabin constants, or passenger count constraints. The description fails to compensate for the absence of parameter documentation.

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 names a concrete action: submit a bounded award-flight search and receive a normalized, validated request echo. However, it is unclear whether this tool actually returns flight availability results or only an echo of the submitted request. The phrase 'honest availability semantics' adds ambiguity rather than clarifying the tool's core purpose.

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?

There is no guidance on when to use this tool versus alternative search or flight-related tools. It does not explain prerequisites, expected input conventions, or what kinds of award searches are appropriate. The description offers no situational context to help an agent decide to call it.

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