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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds genuinely useful behavioral detail: fixed 25-per-page pagination and the underlying endpoint (GET /stock_assets.api). No auth or return-shape detail, but for a read-only list tool this is solid added context.

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 compact clauses that front-load the purpose and then the pagination/endpoint facts. No filler; every element earns its place.

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 read-only, two-parameter list tool with full schema coverage and no output schema, the description covers purpose, pagination, and endpoint adequately. It could briefly note what each returned item represents, but that 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 coverage is 100%, with both 'page' and 'include_custom_fields' fully documented in the schema. The description's '25 per page' complements the page parameter but adds no other parameter semantics, so the baseline of 3 is appropriate.

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?

Clear verb ('List') and resource ('asset stock'), with a parenthetical clarifying that these are bulk items tracked by quantity per location. This distinguishes it from ezrentout_list_assets (individual assets), though it doesn't explicitly name that sibling. The purpose is unambiguous but sibling routing is only implied.

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 implies this is a paginated listing operation, but gives no explicit guidance on when to use it versus ezrentout_get_asset_stock (single lookup) or ezrentout_list_inventory/ezrentout_search_inventory. Usage context is inferred from the name rather than stated.

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