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 behavioral facts: a fixed page size of 25 and the backing endpoint GET /locations/get_line_item_locations.api. It says nothing about ordering, total counts, or what a location record contains.

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 fragments with the resource front-loaded and no filler. The 'status all, active or inactive' clause is slightly telegraphic and the raw endpoint path is arguably noise for an agent that cannot call URLs directly.

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 two-parameter read-only list tool with no output schema and no required parameters, the description covers pagination size and filtering, which is most of what is needed. It stops short of describing what a returned location looks like or how pagination metadata is surfaced, which matters given there is no output schema.

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%, so baseline is 3, but the description contributes the page size ('25 per page') which the schema never states and which directly determines how many page calls an agent needs. It also restates the status enum values, giving no extra syntax or default detail beyond the schema, hence not a 5.

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 names the resource ('The company's locations') and its shape (paginated list with a status filter), which is enough to separate it from single-resource siblings like ezrentout_get_location. It never uses an explicit verb, relying on the title 'List locations' to carry that, and it does not distinguish itself from adjacent list tools such as ezrentout_get_location_quantities.

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 statement of when to use this versus ezrentout_get_location, ezrentout_get_location_quantities, or the many other list_* tools. The only hint is the status filter, which implies browsing active/inactive locations, but no alternative or exclusion is named.

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