Nagios Host Status Tool

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

Annotations already declare readOnlyHint=true, so the safe-read profile is covered. Beyond the word 'current' (implying a live, non-cached lookup), the description adds no behavioral context such as authentication requirements, rate limits, or how unreachable hosts are reported.

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 front-loaded sentence with zero filler; the verb and resource come first. Nothing is padded or redundant.

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-value explanation is unnecessary, and the lone parameter is fully documented in the schema. What is missing is sibling differentiation and any hint of the read's behavior on unknown or unreachable hosts, which matters given eight related Nagios tools.

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?

With a single parameter at 100% schema description coverage, the schema fully documents host_name and its length constraints. The description offers no additional semantics beyond confirming the target is a host.

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 (Get) and resource (current status of a Nagios host), so the operation is unambiguous. However, it does not differentiate itself from close siblings such as nagios_service_status_tool, nagios_program_status_tool, or nagios_current_problems_tool, leaving the agent to infer scope from the name alone.

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?

There is no statement of when to use this tool versus the sibling status tools (host vs service vs program vs current problems), nor any prerequisites or exclusions. Usage is only weakly implied by the word 'host'.

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