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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that the report aggregates queue and topic dead letter counts, which is useful scope information, but says nothing about report format, size, latency, or whether it queries live vs cached data.

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?

A single front-loaded sentence with no filler; the parenthetical efficiently names the report's contents. It is perhaps overly terse given the dense sibling namespace, but every word 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?

An output schema exists so return values needn't be described, and all three parameters are optional and documented. What is missing is the differentiation from the crowded azure_servicebus_* family, which is the main thing an agent needs to call this correctly.

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% (context_id, environment, azure_tenant_id are all documented with auto-detection behavior), so the schema carries parameter meaning. The description adds nothing about parameters, which is acceptable at full coverage and yields the baseline 3.

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 ('Generates') and resource ('Service Bus report') and scopes the content to queues and topics with dead letter counts. However, it does not distinguish this from the many sibling Service Bus tools (azure_servicebus_health_overview, azure_servicebus_queues, azure_servicebus_topics, azure_servicebus_dlq_content), so an agent cannot tell from the description which one to pick.

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?

No guidance on when to use this report versus azure_servicebus_health_overview or the individual queues/topics tools. The word 'automatic' is not explained (scheduled? on-demand?) and there are no prerequisites or exclusions stated.

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