get_daily_summary

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

No annotations are provided, but the description does not disclose behavioral traits beyond its purpose. It does not mention read-only nature, rate limits, or authentication needs. With an output schema, the return value is somewhat covered, but the description lacks additional behavioral context.

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 at three sentences, with the first sentence stating the purpose and the second providing usage guidance. It is front-loaded and contains no unnecessary information.

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?

While the description provides good usage guidance and purpose, it lacks parameter explanations. Given 4 parameters (0 required) and an output schema, the description is not fully complete without parameter details. The output schema likely covers return values, but the missing parameter descriptions reduce completeness.

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%, meaning the schema provides no parameter descriptions. The description does not explain any parameters (raw, end_date, days_back, start_date), relying solely on parameter names which may not be self-explanatory for all users.

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 clearly states it provides a daily summary of sleep, readiness, and activity scores. It distinguishes itself from sibling tools by positioning itself as the starting point for the most frequent request.

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 description explicitly advises to start with this tool and then use get_sleep and others for details, providing clear context on when to use this tool versus alternatives.

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