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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states 'daily OHLCV data' and 'CryptoCompare-compatible format' but does not disclose whether the data is historical, any rate limits, or how the response is structured. This leaves gaps in understanding safety and side effects.

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 concise sentence that effectively communicates the tool's purpose without unnecessary detail. It is well-structured and front-loaded, earning its place.

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?

With no output schema and no annotations, the description provides only minimal context. It does not clarify the exact output structure or any usage caveats. However, for a simple data retrieval tool with well-documented parameters, it reaches an adequate but not complete level of coverage.

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 coverage is 100%, with all parameters having descriptions. The description does not add any parameter-specific details beyond what the schema already provides, so the baseline score of 3 applies. The 'daily' qualifier helps contextualize but not at the parameter level.

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 uses a specific verb 'Get' with a clear resource 'daily OHLCV data', and the mention of 'CryptoCompare-compatible format' adds useful context. It distinguishes itself from sibling tools like get_histohour and get_histominute by specifying daily granularity.

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 alternatives. The 'daily' qualifier implies it is for daily data, but it doesn't mention when to prefer get_histohour or get_histominute for intraday data, or get_ohlcv for general OHLCV. Usage is only implied.

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