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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds useful domain context (these are portal/staff requests not yet converted, endpoint GET /requests) but says nothing about result volume, pagination behavior, or that includes expands referenced ids inline.

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?

One sentence plus the endpoint path — no padding, and the resource and lifecycle qualifier are front-loaded. The parenthetical is doing real work; the trailing "GET /requests" is slightly redundant but harmless.

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 16-parameter read-only list tool with no output schema, the description covers the domain meaning of the resource and relies entirely on the schema for filters, sorting, and pagination. That is defensible given 100% coverage, but the incorrect status vocabulary is a real correctness gap, and there is no word on page limits (1-100) or what comes back.

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 all 16 parameters are already documented, which would normally justify a 3. But the description actively misinforms about the most important filter it mentions: it lists statuses "open/approved/rejected" while the request_status enum is requested/declined/approved. An agent taking the description at face value would pass an invalid enum value; the rest of the parameters get no description-level elaboration.

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 specific verb and resource ("List work requests") plus the lifecycle position: pre-work-order, submitted by staff or the request portal. That distinguishes it from list_work_orders and get_request without the agent opening a schema. However, the stated statuses ("open/approved/rejected") do not match the actual request_status enum, which muddies the resource definition.

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 phrase "before they become work orders" implicitly tells the agent this is the pre-conversion queue and hints that list_work_orders is the post-conversion counterpart, but it never says so explicitly. There is no when-not guidance, no mention of get_request for a single item, and no note about which filters matter most.

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