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

The description adds a URL and a return type (pandas.DataFrame), but it does not describe what data is contained, whether it is historical or current, what the DataFrame columns are, or any other behavioral details. Annotations already declare the tool read-only and safe, so the description adds minimal context beyond what annotations provide. It does not contradict the annotations.

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 very short, but it is repetitive: the first line duplicates the tool's title, and the ':return:' line repeats the same phrase. This is under-specification rather than purposeful conciseness. The URL is the only non-redundant piece of information, so the structure wastes its brevity on redundant content.

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?

For a simple fetch tool with no parameters, the annotations cover safety, but the description does not explain the data contents or structure. The lack of an output schema means the agent has no idea what columns, time range, or granularity to expect from the returned DataFrame. The URL and return type alone are insufficient for a complete understanding of the tool's output.

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 tool has zero parameters, so the description does not need to explain parameter semantics. The input schema is trivially complete (100% coverage), and for 0 params the baseline is 4. The description adds no parameter-specific information, but none is required.

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 restates the tool's title '东方财富-本外币存款' without any action verb like 'fetch' or 'retrieve.' The only additional information is a source URL and a return type, which do not clarify what the tool actually does. This is a tautological description that lacks a clear purpose statement and does not distinguish it from sibling tools.

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 no context about when to use this tool or how it differs from similarly named macro_* tools. There are no alternatives mentioned, no exclusions given, and no indication of the appropriate scenario for invoking this tool. An agent would have zero guidance on usage.

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