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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive, so the bar is lower. The description adds a source URL and return type (pandas.DataFrame) but does not disclose any behavioral traits such as data coverage, pagination, or potential network dependency. It adds little beyond the annotation safety profile.

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 but contains a redundant first line that exactly matches the title. The structure is docstring-like with URL and param/return, but the repeated title wastes space. It is not as concise as it could be.

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 one optional parameter and no output schema, the description should clarify what data is returned and how it differs from similar tools. It only says it returns a DataFrame of executive shareholding changes from THS, without describing columns, date ranges, or use cases. This is insufficient for a tool with many 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?

The schema has 0% description coverage, so the description must compensate. It only states 'symbol: 股票代码' (stock code), which is already obvious from the parameter name. No format, examples, or default behavior details are given, so the parameter semantics are minimal.

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 is '同花顺-公司大事-高管持股变动', which is identical to the title and essentially restates the tool name. It provides no verb or explicit action, only a noun phrase describing a data category, and does not differentiate from sibling tools like stock_hold_management_detail_em.

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?

No guidance is provided about when to use this tool versus alternatives. The description only contains a URL and parameter documentation, with no mention of preferred use cases, exclusions, or related tools.

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