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. It reveals only that results are upcoming and confirmed, saying nothing about the time window covered, ordering, whether cancelled or tentative bookings appear, or any auth requirements.

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 front-loaded sentence with no filler, appropriately sized for a one-parameter read tool. Every word contributes to scope.

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 read tool with one fully documented parameter, this is close to adequate, but with no output schema the description should say more about what comes back (fields, ordering) and what "upcoming" means as a time horizon.

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 coverage is 100% and the single limit parameter includes its default, so the schema does the work. The description adds nothing about the parameter, which is acceptable at this coverage level.

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?

States a specific verb (List) and a specific resource scope (upcoming confirmed appointments and client meetings). It's clear what the tool returns, but it doesn't reference any sibling such as get_available_slots or get_analytics_summary to sharpen the boundary.

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 word "confirmed" implicitly distinguishes this from get_available_slots (unbooked capacity) and create_booking, so a careful agent can infer when to use it. However there is no explicit when-not guidance, no mention of alternatives, and no statement of preconditions.

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