icu_create_sport_settings

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

Annotations already indicate a write operation (readOnlyHint=false). Description adds the condition that the sport must not have an existing record, but lacks detail on error handling or side effects if the condition is violated. No contradiction with annotations.

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?

Single sentence that is front-loaded with key information and contains no unnecessary words. Efficiently communicates the tool's purpose and condition.

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?

With full schema coverage and an output schema present, description covers essential purpose and condition for use. Mentions the threshold variants but could briefly note that only sport_type is required.

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 coverage is 100% with clear descriptions for each parameter. Description adds minimal extra context by naming the threshold types (FTP, FTHR, pace, swim) but does not significantly enhance understanding beyond schema.

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?

Clearly states the verb 'create', resource 'per-sport threshold record', and scope 'for a sport that doesn't have one yet'. Distinguishes from sibling tools like icu_get_sport_settings (read) and icu_update_sport_settings (update).

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?

Implicitly indicates when to use by stating 'for a sport that doesn't have one yet', but does not explicitly exclude alternative tools like icu_update_sport_settings for existing records. Provides clear context for creation scenario.

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