stock_hk_profit_forecast_et

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds the data source URL and return type but no further behavioral context like rate limits, pagination, or authentication requirements. It does not contradict 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 short and front-loaded with the tool's purpose and source. However, it redundantly repeats the title and includes a docstring-style layout that could be more concise. Overall, it is appropriately sized and every element contributes to understanding.

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 only two optional parameters and no output schema, the description gives reasonable parameter guidance but fails to explain the structure of the returned DataFrame beyond '盈利预测'. An agent may not know which columns or values to expect. It is minimally adequate but has noticeable gaps in output context.

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 0%, but the description compensates by documenting both parameters: symbol as stock code with default 09999, and indicator with allowed choices (评级总览, 去年度业绩表现, 综合盈利预测, 盈利预测概览) and default. It does not specify symbol format details (e.g., zero-padding), but provides essential selection info.

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 the tool as 经济通-公司资料-盈利预测 (ETNet Company Data - Profit Forecast) with a source URL, making clear it retrieves profit forecast data for HK stocks. It distinguishes from siblings like stock_hk_profit_forecast_em by specifying the ETNet source, though it lacks an explicit verb phrase.

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 parameters but no guidance on when to use this tool versus alternatives such as stock_hk_profit_forecast_em or stock_profit_forecast_ths. It does not state scenarios, exclusions, or selection criteria, leaving the agent to infer from the source URL alone.

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