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

Annotations already flag a non-destructive but non-idempotent, open-world write; the description adds the crucial nuance that it 'creates a ticket; it never changes the policy,' which explains why destructiveHint is false despite being a write. It also discloses the response timeline ('follows up by the next business day') and the message length bound, none of which appear in structured fields.

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?

Four short sentences, each earning its place: eligibility gate first, then action plus scope, then the ticket/no-policy-change distinction, then timing and the message bound. The parenthetical enumeration is long but replaces missing schema documentation for the topic enum.

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?

With no output schema, the description does the right work by explaining the outcome (ticket created, agent follow-up next business day) and the read/write boundary. It stops short of explaining what client_session is or whether a policy_id is needed for policy-specific asks, which matters for a five-parameter write tool.

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 0% across five parameters, so the description must carry the load. It well documents the message constraint (10 to 2000 characters) and implicitly maps the parenthetical scenarios to the topic enum, but says nothing about client_session, policy_id, or preferred_contact, leaving most parameters unexplained.

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 concrete verb and resource ('sends a service request to a licensed Hutsenpiller agent') and enumerates the covered scenarios (vehicle/driver changes, mortgagee, home coverage, billing, documents, cancellation, account review), so the agent knows exactly what the tool handles. It does not explicitly distinguish itself from siblings like request_agent or submit_quote, keeping it just short of a 5.

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?

'Current clients only' states a hard eligibility precondition, and the parenthetical list of scenarios effectively defines when the tool applies. However, it never names an alternative for other cases (e.g., request_agent, submit_quote, get_coverage_summary) or states when not to use it, so routing between siblings is left to inference.

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