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

Annotations already declare this as a read-only, non-destructive, closed-world query. The description adds that it spans all Service Bus environments and can be scoped by environment, which is useful scope information, but it does not explain aggregation behavior, what 'general health' means, or permission requirements.

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, front-loaded with the core action and scope, with no wasted words. The optional filter is stated immediately after the primary behavior.

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?

The tool is simple and has an output schema, so return-value detail is not required. However, the description does not resolve the overlap with azure_servicebus_namespace_health or clarify whether 'all Service Bus environments' means the dev/tst/pre/prod environment dimension or Azure namespaces.

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 context_id, environment, and azure_tenant_id. The description restates the environment enum values and the 'all' option but adds nothing about tenant defaulting or context handling beyond what the schema provides.

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 clear verb and resource: show general health status of all Service Bus environments, with optional environment filtering. It is understandable, but it does not differentiate itself from the sibling azure_servicebus_namespace_health, which plausibly covers similar ground.

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 says the environment filter is optional and can be 'all', which gives minimal usage context. It does not say when to prefer this over azure_servicebus_namespace_health or azure_servicebus_monitoring_report, even though those siblings clearly overlap.

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