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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is clear. The description adds that the response includes recent workouts and downloadable items, but it does not explain defaults, ordering, pagination, or omitted settings for the optional filters.

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?

Two sentences, front-loaded with the return value and followed by a concise usage cue. There is 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?

An output schema exists, so return-value details need not be repeated, and annotations cover the safety profile. However, with five optional parameters and zero schema descriptions, the description is only minimally complete for invocations that need filtering or inclusion controls.

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 all five parameters are undocumented. The description mentions no parameter names or meanings, so an agent gets no guidance on limit, days_back, or the include_* flags beyond the bare schema types.

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 states a specific verb and resource: it returns a dashboard summary containing latest workouts with stats and ready-to-download items. This clearly distinguishes the tool's core purpose, though it does not explicitly contrast itself with related workout-listing or detail 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?

It gives clear triggering contexts: when the user asks about the dashboard, recent workouts, or content ready for download. It does not state when not to use it or name alternative sibling tools, but the usage context is explicit enough.

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