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

Annotations already declare a non-read-only, non-destructive, non-idempotent write, and the description is consistent with that ('records', 'helps voidjet decide what to add'). It adds genuinely new behavioral context beyond the annotations: the 'no personal data' privacy guarantee and the 1-5 category cap. Does not describe durability or visibility of the submission, which is why it is not a 5.

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?

Front-loaded with the core action, then constraints, then benefit — efficient for the amount of ground covered. Minor redundancy: 'for when the user wants voidjet to know about it' and 'Helps voidjet decide what to add' restate the same rationale.

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?

With an output schema present, return details need not be explained, and the description covers purpose, trigger, input shape, and privacy. The only real gap is the unmentioned aircraft_class parameter and any indication of what happens after the report is filed (only loosely implied by 'Helps voidjet decide what to add').

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% across 8 parameters, so the description must carry the load. It names categories (1-5), route, dates, passengers and budget, but omits aircraft_class entirely and gives no format or range hints for the fields it does name. Partial compensation against a zero-coverage schema.

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 and resource ('Records a need voidjet cannot serve') with concrete examples of qualifying situations (no offer on route, return flight, pets, instant booking). This separates it from the retrieval/quote siblings like search_empty_legs or request_charter_quote, though it never names any sibling 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 a clear triggering condition ('for when the user wants voidjet to know about it') plus enumerated scenarios that map to the enum categories. It does not state when NOT to use it or point to an alternative such as request_inquiry or create_flight_alert, so the agent must infer the boundary.

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