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

With no annotations provided, the description must disclose behavioral traits. It reveals that the tool is premium, requires x402 payment of $0.05, and new wallets receive 5 free units. However, it does not mention whether the operation is read-only, error handling, or rate limits, though the payment and cost disclosure is significant.

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 well-structured, front-loading the premium/payment notice and then specifying the scoring logic and output format. It is a bit dense with emojis and URL, but every sentence provides relevant information.

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 the lack of output schema, the description compensates by specifying the return format (score and rating). It also covers the payment requirement and free unit policy. However, it does not clarify the minimal parameters needed for a successful call or potential error responses.

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?

All three parameters have schema descriptions, so the baseline is 3. The description adds no additional meaning about how the parameters interact, such as whether 'query' or 'address' is preferred or if 'chain' is required. It relies on the schema's 100% coverage.

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 clearly identifies the tool as a composite momentum scoring service, listing specific inputs (volume surges, price acceleration, buy pressure, boost activity) and output (0-100 score with COLD/WARMING/HOT/EXPLOSIVE rating). It distinguishes itself from sibling tools like rug_check or viral_score by focusing on momentum.

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 the tool is for assessing token momentum but provides no explicit guidance on when to use it versus alternatives like viral_score or whale_watch. No exclusions or comparison to sibling tools are given, so usage context is only inferred.

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