health_check

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states what the tool does but lacks details on behavioral traits: it doesn't specify what 'health status' includes (e.g., server uptime, API latency, authentication status), whether it performs active tests or returns cached data, error handling, or typical response format. This leaves significant gaps for a tool that might be critical for system diagnostics.

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 that directly states the tool's purpose without any fluff or redundant information. It's appropriately sized for a simple tool and front-loads the essential information efficiently.

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's potential complexity in diagnosing server/API issues, the description is incomplete. With no annotations and no output schema, it fails to explain what the health check returns (e.g., status indicators, metrics, error details) or how to interpret results. For a diagnostic tool, this omission could hinder effective use by an AI agent.

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 0 parameters with 100% schema description coverage, so the schema fully documents the absence of inputs. The description appropriately doesn't add parameter details beyond this, as none are needed. A baseline of 4 is justified since no parameters exist to explain, and the description doesn't introduce unnecessary complexity.

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 action ('Check') and target ('health status of the Renpho MCP server and API connection'), providing a specific verb+resource combination. However, it doesn't explicitly differentiate from sibling tools like 'get_current_user' or 'get_measurements', which serve different purposes rather than being direct alternatives for health checking.

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 description implies usage when health status needs verification, but provides no explicit guidance on when to use this tool versus alternatives (e.g., for troubleshooting connectivity issues before calling other tools). There's no mention of prerequisites, frequency recommendations, or error scenarios that would trigger its use.

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