create_run_intervals_workout

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

No annotations are provided, so the description carries the full burden. It does disclose that the tool creates a workout and uploads it to Garmin Connect, which is important side-effect information, but it omits permissions, reversibility, rate limits, and error behavior.

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?

Front-loaded purpose statement followed by a clean Args list; no filler. Could be slightly tighter by merging defaults, but it is well-structured and easy to scan.

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?

Given seven parameters, no annotations, and an output schema that handles return values, the description covers purpose and all parameter semantics. It is missing explicit usage context and deeper behavioral details, but is otherwise complete enough to invoke correctly.

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%, and the description fully compensates by documenting all seven parameters with meaning, units, defaults, and examples (e.g., distance_m in meters, hr_zone Z1-Z5). This adds substantial value beyond the bare schema titles.

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?

Specific verb 'Create' and resource 'track-style running interval workout', with scope 'upload to Garmin Connect' and a distinguishing detail about distance-based work intervals. Clearly separates it from sibling run workout creators like create_run_easy_workout or create_run_tempo_workout.

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 workout type implies when to use it (track-style intervals with distance-based ends), but there is no explicit when-to-use guidance, no mention of alternatives, and no exclusions. An agent must infer the context from the name and description.

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