Scheduled workouts

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

The annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds the default-to-current-month behavior and monthly scoping, but it does not disclose output shape, pagination, timezone handling, or how scheduled workouts differ from ordinary workouts.

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?

A single front-loaded sentence that states the action, the scope, and the default. Every word earns its place and there is no redundant detail.

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 read-only list with two optional parameters, the description is minimally viable. Still, it lacks any relationship guidance to garmin_list_workouts and does not mention what a scheduled workout entry looks like in the response.

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 0%, so the description carries the burden of explaining the two parameters. It clarifies that the month defaults to the current one, but it never explains the year parameter, valid ranges, or how null year/month combinations behave.

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 a concrete operation ('List workouts') and a bounded resource ('scheduled in a given month'), and it adds the default-month behavior. However, it does not explicitly differentiate itself from garmin_list_workouts or garmin_schedule_workout, so it stops short of a 5.

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?

There is no guidance about when to use this tool versus garmin_list_workouts, garmin_schedule_workout, garmin_unschedule_workout, or other siblings. The only usage hint is the month default, which is a parameter behavior rather than an explicit selection rule.

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