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

With no annotations, the description carries the full burden, and it does disclose the two observable outputs (reachability, version), which is meaningful given there is no output schema. It does not state that this performs a network/probe call that may hang or time out, nor explicitly confirm it is side-effect-free, so a small gap remains.

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 short sentences, zero filler, with the purpose front-loaded and the usage guidance appended. Every clause 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?

For a zero-param diagnostic with no output schema and no annotations, the description supplies the essential missing pieces: what is checked and what is reported. It could be more complete by describing failure/timeout behavior, but nothing critical for correct invocation is absent.

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 to document beyond the schema's empty object and the baseline of 4 applies. The description correctly implies a no-argument invocation and adds no contradictory parameter guidance.

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?

Specific verb ("Check") plus a concrete resource (the AnvaiOps deployment this server is wired to) and the exact facts returned (reachability and version). It is clearly distinguishable from the sibling memory_search/memory_write tools, which read or mutate memory rather than probe the backing deployment.

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 second sentence gives explicit usage context: diagnose connectivity before blaming the tools. That is a real when-to-use directive. It stops short of naming an alternative tool or a when-not-to-use condition, so it falls just below the top band.

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