Google Health Daily Rollup

google_health_daily_rollup
Read-onlyIdempotent

Aggregate daily health metrics from Google Health—steps, distance, calories, active minutes, weight, and heart rate summaries.

Instructions

Aggregate a data type over civil days using Google Health dailyRollUp. Useful for steps, distance, calories, active minutes, weight and heart summaries.

Other valid kebab-case slugs are also accepted.steps

Behavior3/5

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

Annotations already indicate readOnlyHint, idempotentHint, and non-destructive behavior. The description adds that it aggregates over civil days, which is consistent, but does not reveal additional behavioral traits beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: two short sentences that front-load the purpose and examples with no unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (9 parameters, 3 enums, pagination), the description is too brief. It omits details on date range semantics, window_size_days effect, pagination, and privacy options, leaving the agent under-informed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With only 33% schema description coverage, the description should compensate but does not explain key parameters like start_date, end_date, window_size_days, or pagination. It only indirectly references the data_type parameter through examples.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it aggregates a data type over civil days, with examples like steps and distance. However, it does not distinguish itself from related sibling tools like google_health_rollup or google_health_daily_summary.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description suggests it is useful for common health metrics, but it does not specify when to use this tool versus alternatives, nor does it mention prerequisites or exclusion criteria.

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