icu_bulk_create_workouts

Bulk-create multiple structured workouts into library folders or plans in one call, ideal for filling training plans without calendar scheduling.

Instructions

Save MANY new reusable workouts into LIBRARY folders or plans in one call — e.g. filling out a training plan.

Each item is shaped like an icu_create_workout call. Nothing lands on the calendar: for dated calendar workouts use icu_bulk_create_events, and to schedule a finished plan use icu_apply_training_plan.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`workouts`	Yes	JSON array of workout objects, each shaped like an icu_create_workout call. Required per workout: folder_id, name. Optional: description, workout_type, day, duration_seconds, distance_meters, training_load, target, indoor, color, tags. For WORKOUT events the server parses this into structured, device-syncable steps with zones and a training load. Use Intervals.icu workout syntax: one step per line as '- <duration> <target>' (duration FIRST), grouped under Warmup / Main / Cooldown headers. Targets: bike '- 5m 85%', '- 5m Z4', or absolute '- 5m 210w'; HR '- 10m 70-80% HR' or '- 10m 145bpm'; run/swim pace '- 5m Z2 Pace', absolute only with a trailing 'pace' word: '- 5m 4:45/km pace', '- 200mtr 1:45/100m pace' (bare '5:00/km' or '1:45/100m' silently drops); threshold is relative — run '- 25m 100% pace', swim CSS '- 200mtr 100% pace' — the words 'threshold'/'CSS'/'5K pace' are NOT parsed as targets. Add cadence to any step: '- 3m Z2 90rpm'. No target: '- 20m free'. Repeats: put 'Nx' after a section name with steps flat beneath, and leave a blank line before and after the repeat block (without it the repeat silently runs only once) — e.g. 'Main 5x' then '- 3m 110%' / '- 3m 50%'. Ramps: '- 10m ramp 50-70%'. Rest: append 'Ns rest' to a step ('- 200mtr Z2 20s rest') or use a separate '- 20s intensity=rest' step (only intensity=rest exports as a device rest step) — never a bare '- 20s' step (that becomes work, not rest). Durations: 'm'=minutes, 's'=seconds; distance steps use 'mtr'=meters / 'km' / 'yrd' (e.g. swim '- 400mtr Z2 Pace'). Do NOT write '[repeat 5x ...]', nested bullets, or 'Z5 3m' (target before duration). Runs need a pace or HR target — a bare 'Z2' gives no load.

`athlete_id`	No	Athlete ID (for coaches managing multiple athletes)

A4.5/5.0

Behavior4/5

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

Annotations already indicate a mutating, non-idempotent, open-world operation. The description adds the important behavioral constraint 'Nothing lands on the calendar', clarifying side effects and scope. It does not cover partial-failure behavior or auth requirements, but annotations cover the safety profile, so the added context earns a 4.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four short sentences with no filler. The core purpose is front-loaded in the first sentence, and the alternative routing is packed into the remainder. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the rich schema covering the complex workouts parameter, the presence of an output schema, and annotations, the description is complete enough for an agent to select and invoke the tool correctly. It explains scope, gives examples, and names the alternatives for adjacent use cases.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the schema itself contains an extensive description of the workouts string syntax and athlete_id parameter. The tool description only repeats that items are shaped like icu_create_workout calls, which adds little beyond what the schema already states. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Save'), resource ('reusable workouts'), and scope ('LIBRARY folders or plans'), with an example ('filling out a training plan'). Explicitly distinguishes from siblings by naming icu_bulk_create_events and icu_apply_training_plan as alternatives for calendar use.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit when-to-use and when-not-to-use guidance: 'for dated calendar workouts use icu_bulk_create_events, and to schedule a finished plan use icu_apply_training_plan.' Also notes each item is shaped like an icu_create_workout call, guiding bulk vs single invocation.

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