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

The destructiveHint=true annotation already flags this as a state-changing operation, and the description adds real value beyond it by naming the user-visible consequence (public booking page stops/starts accepting bookings). It still omits that the call flips whatever the current state is (so intent must be reconciled with a prior read) and that no desired end-state can be specified.

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 zero padding: the behavioral effect is front-loaded and the REST endpoint follows as supporting detail. Every clause earns its place.

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 one-parameter, no-output-schema tool, the description covers purpose, effect, and endpoint adequately. The only miss is noting that the toggle is relative to current state (and that the response reflects the new state), which an agent may need in order to avoid redundant flips.

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 single parameter is fully documented in the schema ('The scheduling link id to toggle'). The description adds no format, ID-source, or lookup guidance beyond that, 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?

States a specific verb (toggle) and resource (scheduling link) plus the concrete effect: flipping between active and disabled and thereby controlling whether the public booking page accepts bookings. This distinguishes it cleanly from siblings like savvycal_get_link and savvycal_duplicate_link.

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?

Usage is implied by the effect statement ('changes whether the public booking page accepts bookings'), so an agent can infer this is the tool for enabling/disabling a link. However there is no explicit when-to-use guidance, no note about the state-dependent nature of a toggle, and no mention of checking current state via savvycal_get_link first.

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