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

Beyond the readOnlyHint annotation, the description discloses the returned fields, explicitly excludes sensitive fields, and warns that the vendor route is unpaginated but bounded to 5,000 rows or 2 MiB. It also notes the comma-separated locationId behavior.

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 short and front-loaded: the route, return fields, exclusions and bounds are all stated without filler. Every sentence adds useful context.

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 listing tool with no output schema and only a readOnlyHint annotation, the description sufficiently covers return scope, exclusions and result-size bounds. The missing explanation of acceptAppointments keeps it from being fully 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?

Schema description coverage is 0%, so the description must compensate. It explains that locationId values are sent comma-separated, which adds meaning, but acceptAppointments is left undocumented.

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 a specific verb and resource: it reads staff IDs, names and scheduling flags. It is clearly a list operation, but it does not explicitly differentiate itself from the sibling timetap_get_staff.

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 gives scope by excluding contact details, logins and profiles, but it does not say when to use this tool instead of timetap_get_staff or other sibling tools. No alternatives or preconditions are named.

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