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 genuinely new behavior — a fixed page size of 25 and the underlying endpoint GET /tasks.api. The '[sic, as the vendor spells it]' note on 'in_progess' prevents a caller from silently correcting the value into an error.

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, front-loaded with the resource and page size, followed by the filter options and endpoint. The bracketed spelling aside is slightly heavy but earns its place by preventing a wrong enum value.

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 three-parameter, zero-required, read-only list tool with no output schema, the description covers page size, filter dimensions, valid statuses, and the endpoint. Nothing an agent needs in order to call it correctly is missing.

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 coverage is 100% and every parameter is already documented, including the status list and the pointer to list_work_order_types. The description repeats the filter values and adds the 25-per-page fact, but contributes no syntax or format detail beyond what the schema provides, so 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 and resource ('Maintenance work orders'), plus the pagination model and available filters, which clearly separates it from ezrentout_get_work_order and ezrentout_create_work_order. It never names those siblings explicitly, so differentiation is inferred from the verb rather than stated.

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?

'Optionally by status filter ... or by work order type' implies when the filters apply, but there is no statement of when to reach for this tool versus get_work_order or list_work_order_types, and no exclusions. The routing hint ('from ezrentout_list_work_order_types') lives in the schema, not the description.

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