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

Annotations declare only destructiveHint=false and openWorldHint=false, so the mutation semantics, side effects and permissions are left entirely to the description. The description does not say whether going offline/break stops call delivery, whether the change is reversible, whether an active session is required, or how break interacts with break_reason_id. It only restates the state list already present in the schema.

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?

One well-formed sentence with the resource and scope front-loaded and zero filler. The trade-off is that the brevity comes at the cost of missing behavioral detail rather than trimming redundancy.

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 3-parameter tool with full schema coverage and no output schema, the description is minimally sufficient to select and invoke it. It is still incomplete on the things an agent most needs here: the operational effect of each state and the conditional role of break_reason_id.

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 already documents state, purpose and break_reason_id. The description adds no meaning beyond repeating the enum values (in slightly different order than the schema), which is at the baseline for full-coverage schemas but nothing more.

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 uses a specific verb ('Sets'), a precisely scoped resource ('the acting SautiDesk agent's availability state'), and enumerates the five valid states. No sibling tool performs this action, so sibling differentiation is moot, but the scope ('acting agent's') keeps it from being confused with update_agent.

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: nothing says when an agent should switch to break versus offline, whether this affects inbound call/queue routing, or whether it needs to precede or follow desk_place_call or desk_wrap_call. The agent must infer all of this from the tool name alone.

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