create_brick_bike_run_workout

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

With no annotations, the description carries the full burden. It usefully discloses that the workout is uploaded to Garmin Connect and that Garmin auto-adds T1/T2 transitions, but says nothing about authentication, whether the workout is also scheduled, or what happens on upload failure.

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-loads the one-line purpose and side effect, then presents parameters as a scannable list. The Args formatting is slightly verbose but every line carries parameter meaning.

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 need not be explained, and all inputs are documented. Only the workflow context (scheduling, auth, idempotency of re-uploading the same name) is left unaddressed.

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%, yet the Args block documents all seven parameters with units, defaults, and examples (e.g. HR zones defaulting to Z2/Z3), which is meaningfully more than the bare schema titles and defaults provide.

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 and resource ('Create a brick workout (bike → run)') plus the side effect ('upload it to Garmin Connect'). The two-segment structure distinguishes it clearly from siblings like create_brick_swim_bike_workout and create_walk_run_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?

Usage is implied by the purpose and by the default durations/zones, which suggest a standard brick session, but the description never states when to choose this over create_brick_swim_bike_workout or the single-discipline workout creators, nor any prerequisites.

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