Recent activities

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

With no annotations, the description carries the full burden of explaining behavior. It says the tool returns recent logged sessions and headline stats, but does not state whether this is read-only, how results are ordered, whether pagination exists, or how the athlete parameter affects results.

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 concise sentence and is front-loaded with the main purpose. It avoids bloat, though it may be too terse to compensate for missing paramdetails.

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?

There is no output schema, no annotations, and one parameter is undocumented. The description conveys only a high-level view of the result and does not mention filtering, ordering, or what 'headline stats' concretely includes. For a simple two-parameter read tool it is close but still has important gaps.

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?

The schema documents limit ('How many, newest first. Default 10.') but athlete is left undescribed in both schema and description. The description adds no parameter meaning, so the agent has insufficient info to correctly use the athlete parameter.

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 this tool returns 'recent logged sessions with their headline stats,' which identifies the resource and output focus. It is not a tautology and can be distinguished from siblings like log_activity, but it does not explicitly contrast with them.

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 guidance about when to prefer this tool over siblings such as leaderboard or recap, and no mention of alternatives or exclusions. The intended use is only inferred from 'recent' and 'feed,' so the agent does not receive explicit selection criteria.

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