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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds that results are paginated and maps to the REST endpoint GET /links, which is useful context, but it says nothing about how pagination advances (no cursor/page token is exposed) or what the response contains.

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 action and scope; nothing is padded. The REST endpoint mapping is mildly redundant but harmless.

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 an annotated safety profile, no output schema, and one well-documented optional parameter, this is nearly complete. The only gap is that pagination is mentioned without explaining how to page.

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?

The single optional parameter has 100% schema description coverage, so the baseline is 3. The description only mentions "paginated" generically and adds no meaning beyond the schema's own limit description.

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 ... scheduling links") with a clear scope qualifier ("the authenticated user's"). It does not explicitly distinguish itself from savvical_get_link or savvycal_list_events, so an agent must infer the list-vs-get distinction from the names alone.

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 and no mention of alternatives such as savvycal_get_link for a single link. Usage is only implied by the verb "List"; nothing tells the agent when this tool is the right choice over its siblings.

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