insync_get_appointment_calendar

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered by structured data. The description's added value is describing the packaged calendar view (day, slot, label) and the current-month default, which hints at the response shape in the absence of an output schema, but it says nothing about pagination, volume of results, or completeness of the calendar.

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, front-loaded with the resource and the returned content, then the default behavior. Nothing extraneous is included.

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?

With three optional parameters, no output schema, and read-only annotations, the definition covers the mechanics adequately. It falls short on routing — a caller facing insync_list_appointments and insync_find_appointment_slots has no basis in this text to choose — and on any description of the calendar's return structure beyond a label list.

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% and the from/to defaults and the view enum modes are fully documented in the schema. The description only restates the current-month default already given by the schema and adds no syntax, format, or edge-case detail (e.g. what happens when from > to).

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?

Names a specific verb and resource (get the monthly appointment calendar) and enumerates the returned fields (day, time slot, label). It does not, however, distinguish this from the sibling insync_list_appointments or from the other appointment tools, so an agent cannot tell from the description alone which retrieval tool fits.

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 says what the tool returns but gives no guidance on when to prefer it over insync_list_appointments, insync_find_appointment_slots, or the booking/cancel tools. The only usage-adjacent statement is the default-range behavior, which is a default rather than a selection criterion.

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