get_respiration_data

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

No annotations are provided, yet the description only states basic functionality. It omits critical behavioral details such as authentication needs, rate limits, what happens for missing dates, or the response structure. A more transparent description would include these aspects.

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 only two sentences, no redundant information, and is front-loaded with the core purpose. Every word adds value.

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 simple tool with one parameter and no output schema, the description covers the basic functionality and parameter format. However, it lacks information about the output or error handling, so it is not fully complete. A brief note on return value would move it to a 4.

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 provides no description for the 'cdate' parameter, but the description adds meaningful context: 'Target date in YYYY-MM-DD format'. This compensates for the 0% schema description coverage, making the parameter's purpose and format clear.

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 verb 'Get', the resource 'daily respiration rate readings', and the unit 'breaths per minute', making the tool's purpose unmistakable. It also distinguishes from sibling tools which cover other health metrics like heart rate or 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 description explains the required parameter 'cdate' with format, but lacks guidance on when to use this tool versus alternatives (e.g., no mention of temporal granularity or error conditions). No explicit when-not-to-use or alternative recommendations.

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