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

With no annotations, the description carries the full load, and it discloses the important traits: the quote call itself is free, the report costs $49 via x402, delivery is a written 30-day coverage window, and separate agent/human purchase endpoints exist. What is missing is whether the quote has any latency, expiry, or rate limit.

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, front-loaded with 'Free quote', and the pricing and channel details are packed into the second. Every clause carries information; nothing is padded.

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?

No output schema exists, and the description compensates by stating the quote returns price and delivery, plus the payment mechanics and deliverable shape. Remaining gaps, such as quote validity or report format, are minor for a one-parameter tool.

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?

There is a single parameter at 100% schema description coverage, so the schema already explains 'subject'. The description restates the same scope ('brand, person or issue') without adding format guidance, examples, or constraints. Baseline applies.

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 states precisely what the tool returns: a free quote covering price and delivery for a written 30-day coverage report on a brand, person or issue. That said, the tool name 'indonesia_coverage_report' implies it produces the report itself, and only the description corrects this to a quote. It distinguishes itself from the preview/endpoints siblings by output (a priced report offer), but does not name them.

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?

The description gives channel routing ('Agents buy it at /report/buy via x402; humans use /order') and implies a quote-then-purchase flow, but never states when to call this versus indonesia_headlines_preview or indonesia_news_endpoints. The usage is implied rather than stated.

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