index_analysis_week_month_sw

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

The annotations already declare this as a read-only, idempotent operation. The description adds only the source URL and return type, without behavioral details like network dependency or data freshness; since the safety profile is covered, this is acceptable 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 short and includes the source URL, then a compact docstring. The structure is adequate though the URL line could be integrated, and it does not waste words.

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 tool this may be borderline, but it leaves out what the DataFrame contains (columns, date format) and does not clarify how this relates to the separate weekly/monthly tools. The lack of an output schema heightens the need for a clearer return specification.

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 defines 'symbol' merely as a string with a default, lacking any enum or description. The description compensates by explicitly listing the allowed values {'week', 'month'}, giving the agent the semantics needed to select the appropriate period.

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 primarily restates the tool's title, adding that it returns a date sequence from Shenwan Hongyuan weekly/monthly reports. It lacks a clear verb and does not distinguish from sibling tools such as index_analysis_weekly_sw or index_analysis_monthly_sw, leaving the exact operation ambiguous.

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?

There is no explicit guidance on when to use this tool versus alternatives. It does not mention related sibling tools or any conditions that would make this tool preferable, leaving the agent to infer usage from the name alone.

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