server_health

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

No annotations are supplied, so the description carries the full load; "Return" plus the qualifier "safe" implies a non-destructive read, which is the key behavioral fact for a zero-parameter tool. However, it never explicitly states read-only/no-side-effects, nor whether results reflect a live probe or cached state. With an output schema present, return-value disclosure is fairly excused.

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 enumerated outputs are packed efficiently into one clause, which is the right shape for a no-argument status call.

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-parameter tool with an output schema, the description covers purpose adequately and does not need to explain return values. What is missing is the routing information an agent actually needs: how this differs from validate_server_configuration, service_status, and system_info, and whether the call is cheap enough to invoke routinely.

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 the baseline is 4. Nothing in the description is needed to interpret inputs, and nothing misleads about them.

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 ("Return") plus a concrete resource bundle: server health, version, configuration state, diagnostics status. An agent knows exactly what this yields. It stops short of distinguishing itself from nearby siblings such as validate_server_configuration, create_diagnostic_bundle, service_status, and system_info, so the boundary must be inferred.

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 or when-not-to-use guidance and no mention of the sibling tools that overlap it (validate_server_configuration for validation, system_info for host facts, create_diagnostic_bundle for deeper artifacts). The agent must guess which of several health-adjacent tools to call.

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