Behavior1/5

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

No annotations and no behavioral description. No mention of auth, rate limits, data freshness, or side effects. Just describes retrieval.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Extremely concise with two short sentences. No unnecessary words. Front-loaded with purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a simple retrieval with output schema present, but lacks any behavioral context. Could benefit from minimal details like data granularity or time zone.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Adds format specification 'YYYY-MM-DD' for the date parameter, which is not in schema (0% coverage). For a single parameter with low schema coverage, this provides necessary detail.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states verb 'Get' and resource 'Body Battery levels' with specific parameter 'given date'. Distinguishes from sibling tools like get_activities, get_sleep_data, etc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage context provided. Does not specify when to use this vs alternatives. No mention of prerequisites or limitations.

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