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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does mention x402 pricing ('Turns raw Price 0.01 via x402 (USDC on Base)'), but that phrase is ambiguous and does not clearly describe cost behavior, access requirements, rate limits, latency, or return structure. It discloses the computed signal components but not how the tool actually behaves when invoked.

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 a run-on, colon-heavy construction that mixes a title-like label ('Finance Signal Bundle') with signal details and an unclear pricing fragment. The main action is front-loaded, but the second sentence ('Turns raw Price 0.01 via x402 (USDC on Base)') is confusing and does not earn its place as written.

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?

There is no output schema, so the description should explain what the caller receives, but it only lists metric names without describing the asset universe, timeframe, sector definitions, or result format. It also omits the optional wallet parameter from the description, though the schema partially compensates. For a signal-producing tool in a large family of similar tools, the context is under-specified.

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?

The only parameter, wallet, is fully described in the input schema, including the free-tier credit distinction. Schema description coverage is 100%, so the baseline is 3; the description adds no extra parameter meaning, but none is needed.

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 a clear verb and resource: it 'get[s] live computed signal' from a 'Processed analytics layer over on-chain crypto,' and specifies the exact signal components (30-period percentile rank, 4-period momentum, plain-language trend verdict). It is not a tautology and is generally understandable, though it does not differentiate this tool from sibling processed_crypto_* tools or explain what 'crypto sectors' means.

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 explicit guidance on when to use this tool versus any of its many siblings, such as processed_crypto_trending, processed_crypto_movers, or processed_crypto_global. The phrase 'Processed analytics layer' weakly implies a use case, but no conditions, exclusions, or alternatives are provided.

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