Set Blood Pressure

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

The description adds no behavioral transparency beyond the tool name. Even with the destructiveHint annotation present, the description does not explain whether an existing blood pressure reading is overwritten, what data is affected, or whether any confirmation or errors are returned.

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 sentence with no filler or redundancy, efficiently stating the action and object. It earns its place by plainly communicating the core purpose.

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?

The description and schema allow for basic invocation but full operational context is missing: it does not state whether the tool replaces an existing value, what a response looks like, or when this action is appropriate relative to other health-metric tools. Since there is no output schema, the description must carry more of this context, and it does not.

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 already provides complete descriptions for all five param types, units, and required flags, giving the agent sufficient parameter-level detail. The tool description itself adds no parameter semantics, so it stays at the baseline.

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 uses a clear action verb ('record') and a specific resource ('a blood pressure reading'), distinguishing it from the sibling get_blood_pressure and delete_blood_pressure. It is not a perfect 5 because it omits scope details such as the reading being tied to a timestamp or user, though the schema partially covers those.

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_blood_pressure or create_manual_activity. The verb 'record' implies the intended use, but there is no explicit when-to-use, when-to-avoid, or mention of related write tools.

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