get_daily_overview

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

No annotations are present, so the description carries full behavioral burden. It only states what data is included but does not disclose behavioral traits such as authentication requirements, rate limits, or what happens on dates with missing data. Since it describes a read operation, destructive behavior is not an issue, but transparency is minimal.

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 a single, efficient sentence (11 words) that front-loads the key action and scope. Every word is necessary. No redundant or verbose phrasing. This is an exemplar of conciseness given the tool's simplicity.

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?

Given the tool has one optional parameter, no output schema, and no annotations, the description is moderately complete. It lists high-level categories (sleep, activities, health metrics) but does not detail which specific health metrics are included. It provides a general idea but lacks precision on exact outputs, which is acceptable for a high-level overview 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?

Schema description coverage is 100% for the single parameter 'date', already including format and default behavior. The description adds no additional meaning beyond the schema. Baseline score of 3 applies because the parameter is well-documented in the schema, and the description provides no extra semantic value.

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 the tool's purpose: 'Get a comprehensive daily overview including sleep, activities, and health metrics.' This specifies the action (get), resource (overview), and scope (sleep, activities, health metrics), distinguishing it from more granular sibling tools like get_sleep_data or get_activities.

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?

Usage guidelines are only implied: the description suggests using this when an overview of daily metrics is needed, but lacks explicit when-to-use or when-not-to-use guidance. No alternatives are mentioned, though siblings provide more specific data. The single optional parameter with a default makes usage simple but leaves room for ambiguity.

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