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

With no annotations provided, the description carries the full transparency burden. It discloses that the tool is paywalled, includes the cost ($0.004), explains the analysis approach, and indicates what output is provided (top round-trippers and pool liquidity). It lacks explicit mention of failure modes or rate limits, but the key behavioral aspects (paywall, analysis method, outputs) are covered without contradiction.

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 description is about three sentences and packs a lot: purpose, method, output, and payment instructions. It is front-loaded with the core question and does not waste words. While not ultra-brief, every piece of information is valuable for an agent deciding to use this tool.

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?

Given there is no output schema, the description does a good job of indicating what will be returned (top round-trippers and pool liquidity) and the payment requirement. It does not mention error handling or what happens for invalid mints, but for a simple single-parameter tool, this is reasonably complete. Sibling context is not needed.

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% – the only parameter (mint) is described as 'Token mint address on X1.' The description does not add additional parameter meaning beyond what the schema states, so the baseline of 3 is appropriate. It does implicitly confirm the parameter is used in the endpoint path, but that is minor.

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 starts with a specific question ('Is a token's volume real demand?') and clearly explains the analysis: round-trip analysis of the last 24h, distinguishing wash trading/arbitrage/market making from one-way trades, and returns top round-trippers and pool liquidity. It names the resource (token volume) and the method, making it distinct from siblings like recent_trades or top_traders.

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 implies when to use it: when assessing whether a token's volume is genuine demand. It sets the context (last 24h, round-trip analysis) and mentions the payment requirement. However, it does not explicitly contrast with alternative tools or state when not to use it, leaving some inference needed.

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