Get Authenticated Athlete

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description still earns credit for disclosing what the payload actually contains (name, location, stats summary, bikes, shoes), which is behavioral context the annotations don't provide. It stops short of saying whether the data is cached or how gear entries are shaped.

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?

A single sentence with zero filler, front-loaded with the verb and resource and followed by the field inventory. Every clause earns its place.

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?

For a no-parameter read with no output schema, listing the returned fields is exactly the missing information and it is present. It is slightly incomplete in not clarifying the overlap with strava_get_athlete_stats, which matters given how many sibling tools exist.

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?

There are zero parameters and schema coverage is 100%, so the baseline is 4. The description correctly implies no inputs are required (it is scoped to 'the currently authenticated athlete'), leaving nothing ambiguous.

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 and resource ('Get the profile of the currently authenticated athlete') and enumerates included fields, which clearly separates it from activity/segment tools. It does not, however, distinguish itself from the close sibling strava_get_athlete_stats even though it mentions 'stats summary' as part of its payload — an agent could reasonably wonder which to call.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no alternatives are named. The 'currently authenticated' phrasing implies it is the zero-argument self-profile lookup, but that inference is left entirely to the reader.

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