withings_get_workouts

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

Annotations are absent, so the description carries the burden. It discloses the default 7-day range and optional metric fields, but does not mention pagination behavior, response shape, or what happens when no workouts exist. It provides some transparency but not full behavioral disclosure.

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?

Two sentences with no wasted words. The main purpose and defaults are front-loaded, and the optional metrics are listed efficiently. Every clause contributes 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 read-only fetch tool with no required parameters, no output schema, and no annotations, the description covers the essential behavior: source, default range, and available metrics. It could explicitly mention pagination or comma-separated data_fields, but the schema already documents the parameters, so the description is nearly complete.

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?

Schema description coverage is 100%, so the schema fully documents all four parameters. The description adds the default range ('last 7 days') and example data_fields values, which are small additions. It does not compensate for anything missing since the schema already covers the parameter meanings.

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 the verb 'Fetch', the resource 'logged workouts', and the source 'watch/activity tracker', with a date range default. It clearly distinguishes this from sibling tools like withings_get_activity by emphasizing the workout-log focus.

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 gives default date-range context and mentions optional metrics, which implies when it is used. However, it does not explicitly explain when to prefer this tool over sibling tools like withings_get_activity or withings_get_measurements, so usage guidance is only partially provided.

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