health_check

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

No annotations are provided, so the description must fully disclose behavioral traits. It states the tool 'checks' but does not clarify that it is read-only, has no side effects, or what response format to expect. With an output schema present, the description could at least mention that the result indicates operational status. This lack of transparency is a significant 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 a single, front-loaded sentence with no unnecessary words. It efficiently conveys the core purpose. Perfect for a tool with zero parameters.

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 low complexity (no parameters, output schema exists), the description is sufficiently complete. It covers the essential purpose. However, it could briefly mention that the output (defined in schema) will indicate health status (e.g., ok/error), but this is optional since the schema exists.

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 no parameters, so the input schema is fully covered (100%). The description does not need to explain parameters. According to calibration rules, 0 parameters yields a baseline of 4. The description adds no confusion, so the score remains 4.

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 'Check the health status of the CSV Editor.' It uses a specific verb and resource, and it differentiates well from sibling tools focused on editing or data manipulation. However, it could be more precise about what 'health status' encompasses (e.g., server connectivity, service availability).

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 provides no guidance on when to use this tool versus alternatives, such as other checking tools like get_server_info. For a health check, it would be helpful to indicate that this is a quick ping and not a deep diagnostic. No exclusions or prerequisites are mentioned.

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