Health Check

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'on demand' and 'report server status', but does not state whether the tool modifies anything, requires special permissions, makes network calls, or what side effects (if any) occur. For a diagnostic tool, lack of explicit read-only or safety disclosure is a gap.

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 efficient and to the point, with no wasted words. It front-loads the core purpose. However, it could be slightly more structured by explaining the parameter, but as a standalone sentence it is concise and clear.

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?

Given the tool has one optional parameter and no annotations, the description should at least explain the 'connection' parameter and whether the tool is read-only or has side effects. The description covers the overall function but is incomplete for a tool that has an output schema (which we don't see) and needs behavioral context. An agent might not know how to provide the connection or what to expect.

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?

Schema description coverage is 0%, meaning the input schema provides no descriptions. The description does not mention the 'connection' parameter at all, leaving its purpose and format unexplained. With low coverage, the description should compensate, but it fails to add any parameter semantics.

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 a specific verb (check) and resource (database connectivity) and also adds reporting server status. This distinguishes it from sibling tools that deal with tables, schemas, queries, etc. It's unambiguous and immediately understandable.

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 purpose implies when to use it (for connectivity/status checks), but there is no explicit guidance on when not to use it or how it compares to alternatives. The description does not mention any sibling tools or exclusions, leaving usage mostly inferred.

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