get_weigh_ins

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

No annotations are provided, so the description must fully disclose behavioral traits. It only indicates a read operation ('Get'), but fails to address authorization, rate limits, pagination, or what happens when no records exist. There is no mention of potential side effects or data format.

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 of five words that conveys the essential purpose. It is front-loaded and contains no unnecessary information.

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 two required date parameters and no output schema, the description adequately conveys the core functionality. It could be improved by hinting at the return format or that it returns multiple records, but the current description is sufficient given the tool's simplicity.

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 descriptions for both parameters (startDate and endDate) with pattern constraints, giving 100% coverage. The description adds no additional semantic value beyond the schema, so it meets the baseline for parameter semantics.

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 states 'Get weigh-in records over a date range', specifying the verb (get), resource (weigh-in records), and scope (date range). It is distinct from siblings like 'get_latest_weight' and 'get_daily_weigh_ins' because it explicitly requires a date range. However, it could more directly differentiate from 'get_daily_weigh_ins' which might also retrieve records over a range.

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 provides no usage guidance beyond stating the action. It does not indicate when to choose this tool over siblings like 'get_latest_weight' or 'get_daily_weigh_ins', nor does it mention prerequisites or scenarios where this tool is inappropriate.

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