list_workouts

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

Beyond the readOnlyHint and idempotentHint annotations, the description reveals important runtime behaviors: default date range, 90-day maximum range, the need to chain calls for older periods, and the effect of the saved_workouts flag. This adds meaningful context that annotations alone do not provide.

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 slightly long but well-organized with labeled sections (SAVED WORKOUTS, INFER) and each sentence adds value. It front-loads the core function and usage examples before diving into edge cases, though a bit of trimming could improve 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?

Given the three optional parameters and the tool's role in a broad ecosystem, the description covers all necessary aspects: default dates, range limitations, chaining strategy, saved workout mode, and the output fields. Users have enough context to call it correctly without referencing external docs.

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 descriptions cover all three parameters, but the tool description enriches them further by specifying defaults (start_date = 7 days ago, end_date = today), the meaning of saved_workouts, and instructions to widen the range up to 90 days. This goes well beyond the schema's basic descriptions.

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's function: listing workout sessions with specific attributes (ID, date, focus, location, NSI rating). It also gives concrete usage examples and distinguishes between completed workouts and saved workouts, making its purpose unambiguous.

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 provides explicit guidance on when to use it: before get_workout to find a session ID, for answering trend questions, and how to handle older data via chaining. It also clarifies the saved_workouts flag to switch modes, which helps select the right tool among siblings.

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