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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds that results are paginated and identifies the backing REST endpoint, which is useful context, but says nothing about result volume, default ordering, or what the pagination token/link looks like.

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 core purpose front-loaded and no filler. The REST endpoint mapping is arguably redundant for an agent but is compact enough not to harm readability.

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-only list tool with one optional parameter, the definition is adequate. With no output schema, however, the description does not indicate what an event record contains or whether pagination metadata is returned, leaving a modest gap.

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%, so the single 'limit' parameter is fully documented in the schema itself. The description's '(paginated)' note corroborates the limit's purpose but adds no syntax, defaults, or range detail beyond the schema, making the baseline 3 correct.

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 and resource ('List booked events/meetings') and maps it to the underlying REST call, which is unambiguous. It does not explicitly contrast with sibling list/get tools like savvycal_get_event or savvycal_list_links, so it stops short of full sibling differentiation.

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?

There is no when-to-use guidance, no mention of alternatives such as savvycal_get_event for a single event, and no stated prerequisites or filtering conditions. The agent must infer that this is the broad enumeration tool.

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