delete_workout

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so safety profile is covered structurally. The description adds nothing beyond restating deletion: it doesn't say whether deletion is permanent or reversible, what happens to already-scheduled occurrences of the workout, or whether confirmation/ownership checks apply. With annotations carrying the safety signal the bar is lower, but this adds essentially zero extra context.

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?

One sentence with no waste, appropriately front-loaded. But the brevity is under-specification rather than economy — the sentence is short because it omits necessary detail, not because it is dense.

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?

An output schema exists, so return values needn't be explained, and annotations cover destructiveness. Still missing for a destructive tool: irreversibility, effect on scheduled workouts, prerequisites, and any pointer to the correct ID source. The unresolved overlap with unschedule_workout is the largest gap.

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 must compensate for the single parameter and does not. An agent has no textual indication that workout_id is the identifier returned by list_workouts/create_workout, nor what format or range is valid.

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?

States a specific verb (delete) and resource (saved workout in the user's Garmin library), which distinguishes it from list_workouts, create_workout, and schedule_workout. It stops short of clarifying how it differs from unschedule_workout, the sibling an agent is most likely to confuse it with.

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 when-to-use guidance and no explicit alternative named. The most consequential routing decision here — delete_workout vs unschedule_workout (removing from the library vs removing from the calendar) — is left entirely unaddressed.

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