Behavior3/5

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

With no annotations, the description must disclose behavior itself. It states the primary behavior (returns pong and server time) but omits any mention of the optional message parameter echo behavior. The description does not contradict annotations, and for a simple read-only operation, the core behavior is transparent, though not exhaustive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, front-loaded with the key term 'Health check', and contains zero filler. It effectively communicates the tool's purpose without redundancy, scoring high on conciseness and structure.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple, but the description leaves out the echo behavior of the optional message parameter, which is relevant to the response. Although the schema covers the parameter, there is no output schema, so the description should have been slightly more detailed about the full return value. Minor gap, hence a 3.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for the single parameter 'message', which is described as 'Optional echo message'. The tool description adds no additional parameter meaning, so the baseline score of 3 applies. The schema fully handles parameter semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool as a health check that returns pong and the current server time. This is specific and unambiguous, distinguishing it from all sibling tools which are data retrieval or repository operations. The verb 'returns' and the resource 'server' make the purpose immediately obvious.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'Health check' label implies the tool is used to verify server connectivity, but no explicit when-to-use or when-not-to-use guidance is given. Since there is no alternative health-check tool among the siblings, the usage context is clear but only by implication.

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