List latest cycling activities

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

With no annotations, the description carries the burden of behavioral disclosure. It explicitly states the operation is read-only, explains deduplication behavior, and notes the optional multisport flagging. It does not cover pagination, sorting, or error behavior, but the provided safety and dedup details are valuable.

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 two concise sentences, front-loaded with the action and resource. Every phrase adds value, including the deduplication caveat and the read-only note, with no redundant or filler text.

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 simple list operation with four optional parameters and no output schema, the description gives a reasonable overview but misses key context like date-range semantics, limit usage, and the return format. The dedup and multisport details help, but the tool is not fully specified for an agent to invoke without further inference.

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 explain limit, startDate, or endDate. It only indirectly hints at includeMultisport via 'optionally flagging multisport parent records'. The description does not compensate for the lack of parameter documentation.

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 lists Garmin cycling source records, with specific verbs and resource. It distinguishes from siblings by focusing on Garmin cycling data and mentioning deduplication of Intervals summaries, though the term 'latest' is not restated in the description.

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 provides no explicit guidance on when to use this tool versus alternatives like find_activities or read_series. It implies its purpose through the name and title but lacks exclusions or alternative tool recommendations.

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