Create Single-Use Scheduling Link

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

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=true, so the mutation profile is known. The description adds genuinely useful non-annotation context: it states the call changes Calendly state, requires confirm=true for the specific user-requested action, and names the required OAuth scope scheduling_links:write.

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?

Three short sentences, front-loaded with the action and then the confirmation and scope constraints. No filler, though the first sentence is largely redundant with the title.

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 destructive write with no output schema, the description covers the state change, the confirmation gate, and the authorization scope. The complex nested payload and its file/flag alternatives are fully documented in the schema, so nothing critical is missing, though return behavior and idempotency consequences are left implicit.

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 schema documents owner, account, payload, payload_file and the flags with enums and mutual-exclusion notes. The description only echoes the confirm requirement, adding no detail about the payload vs body-flag vs payload_file alternatives, so the 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 names a specific verb (Create) and resource (Single-Use Scheduling Link), matching the title closely. No sibling tool covers scheduling links, so no disambiguation is needed, but the description never explains what a single-use scheduling link is or why one would be created beyond the name itself.

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 create a scheduling link, no prerequisites beyond the confirm flag, and no alternatives named. The only usage-adjacent content is the mechanical confirm=true requirement, which is a gate rather than guidance on choosing this tool.

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