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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: no mutation/read profile, no auth or cost implications, no output format, no limits. The single duplicated phrase adds zero behavioral context.

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?

Very short, but the brevity comes from under-specification rather than efficiency; the duplicated phrase carries no information. There is nothing to front-load because nothing substantive is said.

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?

A tool with two ambiguous string inputs, no annotations, and no output schema needs the description to explain input shape and return value. None of that is present, leaving the definition unusable 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?

Schema coverage is nominally 100%, but the field descriptions are vacuous ("Text to process", "Input to process") and give no semantics at all. The two parameters 'text' and 'input' look overlapping, and the description does nothing to disambiguate which to supply or how they differ.

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 is "Quote Extract: Quote Extract", a verbatim restatement of the tool name with no added information. It never states what a quote is, what is extracted from, or what differs from siblings like x402-keyword-extract or x402-ai-extract.

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 when-to-use guidance, no prerequisites, and no mention of any alternative tool. An agent has no basis for choosing this over the many other extraction siblings.

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