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

With no annotations, the description carries the full burden. It discloses a meaningful trait – it submits externally to Villiers operators and demands explicit human confirmation – which hints at a consequential action. But it omits whether this is reversible, whether it books/charges anything, and any side effects 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.

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

Two tight sentences, front-loaded with the step and action, then prerequisites. No filler or redundancy.

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 an unannotated, externally-facing action with no output schema and low parameter coverage, the description covers the essential sequencing and human-confirmation gate but leaves outcomes, side effects, and most parameters undocumented. Adequate but with clear gaps.

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 only 36% and there are 11 parameters, so the description must compensate. It only clarifies estimate_token's provenance ('from Step 1'); origin, destination, departure_date, email, name fields, and the aircraft_category default are left entirely to the 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: 'Submits confirmed live charter pricing request to Villiers operators'. The 'STEP 2' framing distinguishes it from the estimate sibling (Step 1), so an agent can tell it apart. It's clear, though what 'confirm' actually commits to (request vs. booking) is left slightly ambiguous.

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 an explicit hard prerequisite: a valid estimate_token from Step 1, plus a required 'explicit human confirmation' gate. This effectively routes the agent to geo360_vip_aviation_estimate first. It does not spell out when NOT to use it or how to handle failure/retry, so it falls short of a 5.

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