get_daily_steps

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

With no annotations, the description carries the full burden of behavioral disclosure. It states that data is retrieved but does not mention read-only behavior, authentication requirements, rate limits, pagination, or whether the returned data is aggregated or raw.

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 concise and front-loaded with the action and object. The Args section is directly useful and adds no unnecessary detail.

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 is simple and the description covers the core operation, but it omits return-value details such as the unit of measurement, whether summaries or per-day records are returned, and any constraints on the date range. These are useful for an agent selecting and using the 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 explains the date parameters and their YYYY-MM-DD format, adding value over the bare schema. However, it does not clarify whether the date range is inclusive, whether a maximum span applies, or how timezones are handled.

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 action ('Get steps data') and a clear scope ('for a date range'). It is distinct enough from most siblings, though the name 'get_daily_steps' is needed to clarify that the result is daily step values rather than generic step data.

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?

No guidance is provided about when to use this tool instead of similar siblings such as get_steps_data or get_weekly_steps. The description gives no context about the expected use case or when this tool is preferred.

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