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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It describes the output fields in detail, including scales (0-1, 0-10) and components, which informs the agent of the data shape. However, it doesn't explain error behavior, authorization requirements, or side effects, though the 'Get' prefix implies a read-only operation. This is sufficient for a simple retrieval tool but not rich.

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 single, information-dense sentence that conveys a large amount of return-value detail efficiently. While it could be improved with bullet points, it is not wasteful and all terms are relevant. It front-loads the purpose before listing metrics.

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 absence of an output schema, the description adequately lists the key fields the agent can expect. It covers the core purpose and the primary outputs, and the schema handles parameter details. It doesn't discuss date/version behavior in the description but those are documented in parameter descriptions, so overall it is complete enough for a snapshot tool.

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%, meaning all five parameters have detailed descriptions in the schema. The description does not add parameter-specific information beyond the obvious 'specific crypto asset', so it neither enhances nor detracts from the schema's clarity. Baseline of 3 is appropriate.

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 states the action ('Get') and the resource ('detailed daily insights snapshot for a specific crypto asset'). It distinguishes itself from siblings like get_ticker_history or get_ticker_signals by enumerating unique metrics such as α-index, α-pulse, and narrative intensity, making its purpose unmistakable.

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 provides a clear context: this is for obtaining a comprehensive daily snapshot of a single asset, with a specific set of alpha and sentiment metrics. It doesn't explicitly mention when not to use it or name alternatives, but the scope is unambiguous enough for an agent to select it over sibling tools.

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