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

Annotations already declare readOnlyHint=true, so the safety profile is covered and the bar is lower. The description adds the result field set and the underlying endpoint, which is useful context, but does not disclose pagination behavior, default sorting, or whether the response is paginated beyond what the schema hints at.

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 short sentences with the resource scope front-loaded and the field list and endpoint following compactly. Nothing is redundant and every clause carries information.

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?

There is no output schema, and the description partially compensates by listing the returned fields, while all 10 parameters are documented in the schema. Read-only annotations cover safety. What is missing is pagination/result-count guidance, which is minor for a list tool.

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 100% across all 10 parameters, so filters like isPaid, includeCancelled, the start/end bounds, and pagination are already fully documented. The description's parenthetical enumerates result fields rather than filter semantics, so it adds little beyond the schema baseline of 3.

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 names a specific verb and resource ('List all appointment reservations across the studio') and enumerates the fields carried in the results, so the agent knows exactly what it returns. It also supplies the underlying API route. It stops short of naming a sibling for contrast, though 'across the studio' implicitly separates it from momence_list_member_appointments.

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?

Scope is implied by 'across the studio,' which suggests this is the studio-wide listing versus a member-scoped one, but there is no explicit when-to-use statement, no indication of when to prefer momence_list_member_appointments, and no mention of prerequisites or pagination strategy.

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