get_recent_exercises

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

No annotations are provided, so the description carries the full behavioral burden and it does not deliver: no mention of the recency window, ordering, deduplication, result limits, or whether it is scoped to the authenticated athlete. For a read tool with zero annotation coverage, this leaves the agent guessing at output shape and scope.

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 short sentence with no filler, and the key qualifier ('recently') is front-loaded. It is efficient but so terse that it borders on under-specification rather than disciplined conciseness.

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?

Low complexity and no parameters lower the bar, but with no output schema and no annotations, the description is the only source of truth and it leaves 'recently' undefined and the return contents unstated. An agent cannot predict what it will get back.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; baseline for no-param tools applies. No parameter-level information is expected or missing.

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 the resource (exercises) and a scope qualifier (used recently by the athlete), which hints at a read of recent activity. However, it doesn't say how 'recent' is defined or how this differs from sibling tools like search_exercises or get_workout_history, so an agent cannot cleanly separate it from those alternatives.

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 on when to call this versus search_exercises, get_exercise, or get_workout_history. The agent must infer that this is the 'what did I just do' lookup rather than an explicit routing instruction.

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