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

No annotations are provided, so the description carries the full burden. It merely states it 'returns' health/version but does not explicitly disclose that it is a read-only operation, any authentication requirements, or what the response structure entails. The word 'returns' implies non-destructive behavior, but more transparency is needed for a tool with zero annotation coverage.

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?

The description is a single, clear sentence with no filler. It conveys the essential information efficiently and is appropriately front-loaded.

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 simple health-check tool with no output schema, the description provides a high-level overview of the return value ('server health status and version information'). It does not elaborate on what 'health status' entails, but given the simplicity of the tool and lack of parameters, this is mostly sufficient. Slight gap in not specifying the response format, but overall complete enough.

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 has zero parameters, so the schema fully covers the interface. The description adds no parameter details, which is acceptable. Baseline of 4 is appropriate given no parameter complexity exists.

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 clearly states the tool's purpose with a specific verb ('Returns') and resource ('server health status and version information'). It distinguishes itself from sibling tools like get_api_reference and get_platform_overview, which cover documentation and guidance rather than operational health.

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 intended usage is implied by the tool's nature: to check server status and version. However, there is no explicit guidance on when to use this tool versus alternatives, nor any exclusions. For a simple health check, this may be sufficient, but it lacks explicit usage context.

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