textokit_x402_adoption

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

With no annotations, the description carries the full burden, and it discloses the key non-obvious trait: 0.005 USDC per call, paid via x402 on Base from the caller's wallet. That is a real payment/auth precondition an agent must know before invoking, though return shape and failure modes (unpaid call behavior) are not covered.

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?

Three short sentences, front-loaded with the subject and the price, and the free alternative last. Dense and mostly waste-free, though the first sentence is tagline-flavoured rather than informative.

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 a single-param, no-output-schema tool the description covers price, payment rail, and a free fallback, which is decent. It still omits what a caller actually receives (report structure, sources format, freshness) and never ties the 'section' parameter to the described content.

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 description coverage is 100% and the single 'section' parameter has an inline enum with per-value descriptions, so the schema does all the work. The description never mentions 'section' or the report parts, so it adds nothing beyond that baseline.

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 calls this "x402 Bazaar stats: what agents actually buy, with sources", which conveys the resource but uses a marketing tagline rather than a specific verb, never saying it returns an adoption report. It is distinguishable from siblings mostly because of the unique 'x402 Bazaar' subject matter, not because of any explicit differentiation.

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?

It name-drops textokit_sample as a free sample, which implies a paid-vs-free routing choice, but gives no explicit when-to-use or when-not-to-use guidance. Nothing explains how it relates to siblings like textokit_x402_ping or textokit_source_bounded_summary.

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