get_server_status

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered and the description need not restate it. The description's real contribution is enumerating the returned content categories, which matters because there is no output schema — but it gives no sense of shape, depth, or cost of the call.

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 compact fragment with no filler, and the highest-value items (version, HA nodes, host/problem counts) are listed up front. It is a noun phrase rather than a sentence, which is slightly weaker structurally but wastes no space.

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 zero parameters and no output schema, the description is the only source of return-value information, and it does list the content categories — the essential minimum. It stops short of describing structure or granularity, so an agent knows what topics come back but not in what form.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline is 4. The description correctly implies a no-argument, whole-server query.

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 names the specific resource content this tool surfaces: Zabbix version, HA nodes, proxies, host counts, and open problem counts. That is precise enough to distinguish a server-level overview from siblings such as get_host_details or get_active_problems, even though no sibling is named explicitly and the fragment lacks a leading verb.

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 when-to-use guidance at all: nothing tells the agent to prefer this over get_active_problems for problem counts, or over zabbix_monitoring for general health checks. Usage is only inferable from the fact that the payload looks like an overview, which is left entirely to the reader.

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