B3.1/5.0
Behavior2/5

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

No annotations are present, so the description carries full responsibility for behavioral disclosure. It only states that the tool performs a health check, but does not explain what it returns, whether it makes network calls, what success/failure looks like, or any side effects. This leaves the agent with incomplete expectations.

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

Conciseness4/5

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

The description is extremely concise: 'Health check tool.' It is front-loaded and contains no filler. While it could include a bit more context without harming conciseness, for a zero-parameter tool this brief phrase is appropriately sized and easy to parse.

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?

For a simple health check tool with no parameters, the description provides the essential purpose, but it lacks details about expected output or behavior. The presence of an output schema helps, but the description alone does not tell the agent what a healthy or unhealthy result looks like. It is minimally adequate but not complete.

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

Parameters4/5

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

The tool has zero parameters, and the schema is trivially fully covered. With no parameters, the baseline is 4, and there is nothing the description needs to add about parameter meaning. The description adds no parameter details, but none are required.

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

Purpose4/5

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

The description states 'Health check tool,' which clearly identifies the tool's function as a health/connectivity check. It is distinct from the sibling tools publish_post and preview_post, which involve different resources. The phrasing is a noun phrase rather than verb+resource, but it is unambiguous.

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

Usage Guidelines2/5

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

No guidance is provided about when to use this tool versus alternatives. The description does not mention contexts such as pre-flight checks, monitoring, or verifying service availability. The sibling tools are clearly different, but no explicit usage direction is provided.

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