icu_create_sport_settings

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

The description says 'Create', aligning with annotations (readOnlyHint=false), but does not disclose potential side effects like whether it overwrites existing thresholds for the same sport_type. Annotations already signal it's a mutation; the description adds minimal extra behavioral context.

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?

The description is a single focused sentence (15 words), front-loading the purpose. It is concise but could be slightly more structured by grouping parameter types.

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?

The tool has 6 parameters and an output schema, but the description does not explain parameter interactions, defaults, or behavior on duplicate sport_type. It is adequate for a simple create but not fully complete.

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%, so the schema already documents all parameters. The description only lists types generically without adding new meaning beyond the schema defaults.

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 action ('Create'), the resource ('per-sport threshold record'), and the key threshold types (FTP, FTHR, pace, swim), distinguishing it from sibling get/update tools.

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 use for creating a new threshold record but provides no explicit guidance on when to use or avoid this tool, nor any alternatives. It is adequately implied but not explicit.

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