create_workout

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

The description discloses strict validation and required fields, which is helpful behavioral context. However, with no annotations, it does not mention side effects, authentication, return values, or error behavior, leaving notable gaps.

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?

Two concise sentences, front-loaded with the primary purpose, and every sentence adds essential information without redundancy.

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 the complex nested schema and lack of output schema, the description is incomplete. It fails to explain optional fields, return values, or validation failures, which are critical for a creation tool with a rich data structure.

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?

The description adds some meaning for required fields (title, start_time/end_time ISO 8601, exercises with sets), but the schema has no descriptions for many optional nested properties (e.g., rpe, superset_id, custom_metric). With 0% schema coverage, the description only partially compensates, leaving many parameters unexplained.

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 clearly states the tool's action ('Create a new workout') with a specific verb and resource. It distinguishes itself from sibling tools like update_workout and duplicate_workout by focusing on creation.

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 description implies the tool is for creating a workout, but it does not explicitly state when to use it versus alternatives (e.g., update_workout). No exclusions or alternative tool mentions are provided, leaving usage context only implicit.

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