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

With no annotations, the description carries the full behavioral burden. It discloses one conditional behavior, returning a payment requirement when proof is absent, but leaves undefined what proof means, what happens when proof is supplied, and any side effects, permissions, or failure modes. This is too thin for an ordering action.

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 short sentences with no filler, and the main action is front-loaded. However, for an 8-parameter tool with no schema descriptions, the terseness crosses from concise into under-specified.

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?

Despite 8 parameters, nested objects, no output schema, and no annotations, the description provides only a one-line effect and a single conditional return. An agent would not know how to construct a valid request or interpret the payment requirement, so the definition is not complete enough for correct invocation.

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?

The input schema has 8 parameters at 0% description coverage, and the description adds almost nothing about them. It does not explain mode, hours, shots, license, deadline, location, questions, or declared_purpose; 'proof' is mentioned but is not even a declared parameter, which actively complicates parameter mapping.

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?

Opens with a specific verb and object ('Places an order') and adds a distinguishing conditional outcome about payment requirements. It does not define the domain of the order, but it is clear enough to separate from siblings like check_feasibility or mission_status.

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?

No guidance on when to use this tool versus check_feasibility, capabilities, or mission_status, nor on prerequisites such as proof. The 'when no proof is supplied' clause hints at a payment flow but never states when ordering is appropriate or what alternatives should be used first.

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