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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds the resource scope (helpdesk-configured statuses and custom sub-statuses) and the API endpoint, which is modest value, but it says nothing about pagination limits or result ordering behavior.

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 tightly packed sentences with the main purpose front-loaded and the endpoint trailered. The parenthetical is slightly ambiguous as to whether it describes returned fields or the status_type parameter, but nothing is wasted.

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 parameterless read-only list tool with full schema coverage and no output schema, the description covers the resource, the returned field shape, and the underlying endpoint. Only pagination/return-envelope behavior is unaddressed, which is a minor gap.

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 page, count, and the status_type enum are fully documented in the schema already; baseline 3 applies. The parenthetical field list hints at status_type but reads more as return fields than as input semantics, adding little beyond the schema.

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 (List) and resource (ticket statuses and custom sub-statuses) configured on the helpdesk, and names the fields returned (status_type, status_code, title). No sibling tool overlaps with this resource, so the agent can distinguish it immediately.

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?

The description offers no when-to-use context, no prerequisites, and no alternatives; usage is only implied by the tool name. It does not say whether this is needed to resolve status codes before calling deskpro_list_tickets or deskpro_update_ticket.

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