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

The annotations already declare readOnlyHint=true, so the safe-read profile is covered structurally. The description adds one behavioral trait beyond that — that results are paginated — but says nothing about page sizing, cursoring, or ordering, so the added context is thin relative to what a paginated lister could disclose.

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 operation and its scope. Nothing is redundant or padded; even the REST mapping is compressed to a single clause.

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 lister with full schema coverage and annotations covering safety, the description is nearly sufficient. The remaining gap is the absence of any mention of filtering capabilities or result ordering, which matters for an events list but is not critical for correct invocation.

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?

With a single parameter at 100% schema description coverage, the schema fully documents 'limit'. The word 'paginated' loosely corroborates that this is a paging control, but the description contributes no syntax, defaults, or bounds beyond the schema. Baseline 3 applies.

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 gives a specific verb and resource ('List booked events/meetings'), and the pagination hint plus the REST mapping (GET /events) make the operation unambiguous. It does not explicitly differentiate itself from siblings like savvycal_get_event or savvycal_list_links, but the resource noun is distinct enough that an agent can route correctly.

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 statement of when to use this versus savvycal_get_event for a single event, and no mention of whether filtering (by date, link, or attendee) is possible or should be handled elsewhere. The agent must infer usage purely from the name.

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