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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds the data source URL and return type (pandas.DataFrame), which is useful but does not disclose details like data freshness or potential limitations. No contradiction with 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 concise, containing only the title-like phrase, a URL, and a return type. It is front-loaded and has no fluff, though it might benefit from a clearer statement of functionality. Still, it earns a 4 for efficiency.

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?

Without an output schema, the description carries the burden of explaining what the returned DataFrame contains. It merely says '概念时间表' without describing columns, date ranges, or whether it's a summary or historical timeline. The URL is given but not accessible to the agent. This is insufficient for an agent to confidently use this 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?

There are zero parameters, and the schema is empty, so the description correctly implies no input is needed. The baseline for 0 parameters is 4, and the description confirms the tool takes no arguments by not mentioning any.

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 identifies a specific resource (同花顺 concept board time table) and provides a source URL, but it's essentially a noun phrase without a clear verb. It does not differentiate from sibling concept board tools like stock_board_concept_spot_em or stock_board_concept_hist_em, and the term '概念时间表' (concept time table) is vague about what exactly is returned.

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 on when to use this tool versus alternatives. There is no mention of exclusions or related tools. The description only states what it returns, not the context in which it should be preferred.

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