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

With no annotations, the description carries the full behavioral disclosure burden. It attempts to add a payment/transaction note via 'Turns r Price 0.01 via x402 (USDC on Base)', but the phrasing is garbled and unreliable, and it does not clearly disclose whether this is a read-only query, what authentication is needed, or what side effects or costs apply.

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 short and front-loads the signal purpose, but the final sentence is fragmented and confusing ('Turns r Price 0.01 via x402'). Briefness is not enough when a key sentence fails to communicate its intended message cleanly.

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?

The one-parameter schema reduces complexity, but there is no output schema and the description never ties the tool to orderbook data. It lists signal components and mentions payment, yet omits enough context about what the user receives and when this tool is the right choice among many processed_* siblings.

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 only parameter, wallet, is already clearly documented with its optional nature and free-tier credit implications. The description adds no additional parameter meaning, but the base score of 3 is appropriate because the schema does the necessary work.

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 gives a verb and general resource ('get live computed signal' over 'crypto derivatives') and lists specific analytics outputs, so it is not a pure tautology. However, it never mentions orderbook data, which is the core of the tool name, and the phrase 'Finance Signal Bundle' is vague enough that it could describe many of the processed_crypto_* siblings.

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 guidance on when to choose this tool over alternatives such as processed_crypto_prices or processed_crypto_oi. The description only implies the tool provides computed crypto signal analytics, with no explicit context, exclusions, or comparison to sibling tools.

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