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

Annotations only carry destructiveHint=true with no explanation; the description supplies the reason (live-account creation that may trigger paging/alerting), plus the non-obvious behavioral trait that status and severity are free-form strings server-side validated against account configuration. It does not cover error behavior, idempotency, or permissions, 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?

Purpose and the live-account warning are front-loaded, and the closing endpoint reference is compact. It is slightly redundant, repeating the status/severity free-form explanation that the schema already carries, but overall it earns its length.

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 mutation tool with no output schema and minimal annotations, the description conveys the essential context: live-account side effects, the validation caveat on the two free-form required fields, and the underlying endpoint. Notably absent is any mention of what the response returns or failure modes, but the core calling information is present.

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 the schema already documents all eight parameters thoroughly. The description largely restates the status/severity semantics already present in the schema, adding no format or syntax beyond it; the 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?

The description states a specific verb and resource ('Creates a new incident') and adds critical scope detail ('on the LIVE account'), immediately distinguishing it from the read-oriented siblings like allquiet_get_incident and allquiet_list_incidents. The endpoint reference (POST /v1/incident) further pins down the operation.

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?

It gives clear context for use — this targets the live account and may trigger alerting/paging — which is exactly the condition an agent needs to weigh before calling it. It also advises confirming valid status/severity values before calling. It stops short of naming sibling alternatives (e.g. update_incident for modifying an existing incident), so it is not a 5.

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