get_daily_summary

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It signals a read-only 'Get' operation and a concise aggregated response, but does not explain date fallback behavior, timezone handling, missing-data behavior, or any other operational traits.

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?

One tightly packed sentence front-loads the verb, resource, and metric list. Every word contributes meaning, and no redundant or vague filler is present.

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 single-optional-parameter tool with an output schema, this is close to adequate. The main gaps are the unmentioned date semantics and lack of sibling differentiation, which matter more because there are many similar getter tools and no annotations to fill in context.

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 input schema has only one 'date' parameter with 0% schema description coverage, and the description never mentions it. The word 'daily' weakly implies that the parameter selects a calendar day, but the description does not clarify format, default behavior, or null handling.

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 names a specific action ('Get') and resource ('daily summary') and lists the exact metrics returned (steps, distance, calories, HR, stress, floors, intensity). It is clear what the tool produces, though it does not explicitly differentiate itself from focused sibling tools like get_stress or get_sleep.

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 use case is implied: request this when a concise cross-metric daily overview is needed. However, there is no explicit guidance about when to prefer this over get_activity, get_stress, or other sibling tools, and no exclusions are stated.

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