Sec Extract

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

Annotations already declare openWorldHint=true, readOnlyHint=false, idempotentHint=false, and destructiveHint=false. The description adds useful behavioral context by specifying the HTTP route and x402 payment cost, which the annotations do not cover. However, it does not explain authentication, data source, or what side effects the non-read-only POST may have.

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 text is short and front-loads the title and route, but it is under-specified rather than concise. The title line repeats the name, and the route/payment line is useful but insufficient for an agent to decide what the tool does.

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?

An output schema exists, so return value details need not be explained. Still, the description omits the tool's purpose and the single input parameter's meaning, which are essential for a paid remote extraction tool with non-read-only annotations.

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 schema contains one parameter, 'ticker', with 0% description coverage and no default explanation. The description never mentions the ticker parameter, its expected format, or its role, so it adds no semantic value beyond the bare 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?

The description repeats the tool title 'Sec Extract' and gives only the remote route, without stating what is being extracted or from what source. It does not use a clear verb+resource formulation, and an agent cannot distinguish it from siblings like v1_contract_term_extract or v1_utils_invoice_extract based on 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, when not to use it, or which sibling alternatives are appropriate. The description only lists the route and payment cost, leaving selection entirely to inference.

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