get_athletics_trends

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

With no annotations, the description carries the burden of disclosure. 'Summarize' implies a read-only operation, and the listed metrics indicate what information is returned. However, it does not describe edge cases (e.g., missing data), data granularity, or other behavioral traits, leaving some gaps for an agent.

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 sentence of 13 words, front-loading the core functionality. Every word contributes meaning, with no repetition or fluff.

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?

Despite having only two simple parameters and no output schema, the description is incomplete. It fails to explain the date range semantics, expected output format, or how the summary handles missing data. An agent would have to guess at important operational details.

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%, and the description does not mention the start_date or end_date parameters at all. An agent cannot infer date formats, inclusivity, or how these dates affect the summary, forcing reliance on the raw schema which only provides type and title.

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 uses a specific verb ('Summarize') and names distinct resources (training volume, pace, wellness coverage, VO2 max history). It is clear about what the tool does, but it does not explicitly differentiate from sibling tools like get_performance_metrics or get_recent_athletics_trends.

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?

No guidance is provided on when to use this tool versus alternatives such as get_recent_athletics_trends. There is no mention of appropriate contexts, exclusions, or comparisons to sibling tools.

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