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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description goes further by disclosing the response envelope shape ({ results, count, has_more, next_cursor }), which tells the agent pagination exists and how to continue, and it names the underlying endpoint. It does not cover ordering guarantees or rate limits, so it is not a 5.

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 sentences plus a bare endpoint reference; the purpose leads, details follow, and there is essentially no filler. The middle clause packing seven returned fields is dense but still readable.

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?

With no output schema, the description usefully carries the return shape and pagination signal, and annotations cover the safety profile, so an agent has what it needs to call this correctly. A brief note on default sort/filter interactions or listing combined with filters would make it fully self-sufficient.

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 8 parameters (limit, cursor, customer, territory, sort_order, request_type, created_after, created_before) are already fully documented in the schema. The description only loosely gestures at filtering by naming record fields such as customer, territory and requested dates, adding no syntax beyond the schema. 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 (List) and resource (incoming service requests), and usefully classifies the resource as booking requests and quote requests, which separates it from generic job or booking listings. It enumerates the fields surfaced in each record. It does not, however, explicitly contrast itself with siblings like list_jobs or list_recurring_bookings.

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?

Usage is only implied: an agent can infer this is the read path for service requests, and the filter-oriented framing hints at narrowing results. There is no statement of when to choose this over list_jobs/list_recurring_bookings, nor any prerequisites or exclusions.

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