health_check

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

With no annotations, the description clarifies that the tool performs configuration validation without making API calls, indicating a read-only, local operation. However, it does not detail what 'validate configuration' entails or the format of the output.

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 sentence containing all essential information with no redundant words. Highly efficient.

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?

The description is minimal but adequate for a simple tool with no parameters and an output schema. It provides the key behavioral trait (no API calls). Slightly more detail on what is validated or the return value could improve, but the output schema likely covers that.

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?

No parameters exist, so schema coverage is 100%. The description adds no parameter information, but the baseline of 4 is appropriate given the empty schema.

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 tool name 'health_check' and description 'Validate configuration without making API calls' clearly state a specific verb ('validate') and resource ('configuration'), and distinguish it from siblings like 'ping' by noting no API calls.

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 safe, no-side-effect usage for configuration validation but does not explicitly state when to use versus alternatives (e.g., 'ping' for connectivity). Guidance is implied but not explicit.

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