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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior. The description adds the source URL and return type but does not disclose additional traits like rate limits or data coverage. With strong annotations, this is adequate but not enriched.

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 compact and well-structured as a docstring with a title, URL, parameter docs, and return type. It avoids redundant elaboration, but the return line repeats the title.

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?

The tool has no output schema, and the description only states 'pandas DataFrame' without describing columns or data structure. Parameters and defaults are covered, but behavioral specifics (e.g., how many periods, data availability) are missing. This is a moderate gap for a financial data 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?

The description documents all three parameters with Chinese explanations and explicitly lists allowed values for symbol (资产负债表/利润表/现金流量表) and indicator (年度/报告期), which the schema lacks. This significantly improves parameter understanding, though stock code format is only implied by the example.

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 clearly identifies the tool as fetching East Money HK stock financial statements (三大报表), with a source URL and return type. It distinguishes from siblings by specifying HK stocks and the three major statements, though it lacks an explicit action verb.

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 implies usage for HK stock financial statements via its title and parameter choices, but does not explicitly state when to use this tool over alternatives or provide exclusions. No alternative tools are mentioned.

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