get_wellness_activity_summaries

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that behavior mirrors the official client and that date restrictions follow the official interface, but these are vague and it does not describe rate limits, auth needs, pagination, or return behavior.

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 it repeats the same purpose in Chinese and English and includes two vague sentences about matching the official client. The key date-range scope is present, but the structure is not tightly front-loaded or waste-free.

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 no output schema and a large sibling set including get_daily_summaries and get_daily_steps, the description should clarify how this tool differs and what the summaries include. It only states the date range and an official-interface correspondence, leaving important context gaps.

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 description coverage is 0%: start_date and end_date have no format, timezone, or per-parameter description in the schema. The description adds that the range is an inclusive calendar date range, but it does not specify date string format or constraints beyond referring vaguely to the official interface.

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 states a specific verb and resource: return wellness activity summaries for an inclusive calendar date range. It is clear enough to distinguish from many sibling tools, but it does not explicitly differentiate itself from close siblings such as get_daily_summaries or get_daily_steps.

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?

It specifies that the range is inclusive and that parameters/date restrictions follow the official interface, but it gives no explicit when-to-use guidance, no exclusions, and no named alternatives among the many sibling summary tools.

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