get_today_summary

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

No annotations are provided, so the description must carry the burden of behavioral disclosure. It describes what data is returned (classes held, total attendance, top classes) but does not mention any side effects, auth requirements, or limitations beyond the summary nature. This is adequate but not rich.

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, straightforward sentence that immediately states the tool's purpose and output content. There is no superfluous text or wasted words.

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 tool with one optional parameter and no output schema, the description covers the core output but lacks details on parameter usage and potential edge cases. It gives the essential summary items but does not fully flesh out behavior, making it minimally complete.

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?

With 0% schema description coverage, the description must explain the gym_id parameter. It does not mention the parameter at all, leaving the optional gym_id with default 'demo' unexplained. The agent cannot infer how gym_id affects the summary from the description alone.

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 provides a daily attendance summary, specifically listing what it includes: classes held, total attendance, and top classes. It distinguishes from sibling tools like trainer attendance, class performance, and revenue insights by focusing on the overall attendance dashboard.

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 offers no guidance on when to use this tool versus alternatives. It does not mention exclusions or specific contexts, leaving the agent to infer that it is for daily overviews. Without explicit comparison to siblings, usage guidance is minimal.

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