get_body_battery_events

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

The description gives no information about side effects, read-only nature, return format, or any behavioral details. Since annotations are absent, the description bears full responsibility and fails to disclose anything beyond the action name.

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 extremely concise, with no redundant words or fluff. It directly states the purpose and parameter format, making it highly efficient.

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 many similar tools (e.g., get_body_battery, get_body_composition), the description lacks context about what 'events' specifically means, what the output looks like, or how it differs from siblings. No output schema is provided, leaving the user without a complete picture.

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 single parameter 'date' is explained with a format specification 'YYYY-MM-DD' in the docstring, which is sufficient for usage. However, no further semantic details (e.g., timezone handling) are provided, but the format note meets the basic need.

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 a 'Get' action on 'body battery events data', identifying the resource and verb. However, it does not differentiate from the sibling tool 'get_body_battery', so purpose is clear but not fully distinct.

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 on when to use this tool versus alternatives like 'get_body_battery' or which conditions apply. The description just restates the function name without any context for selection.

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