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

The description discloses that the tool makes a real network round trip to an external API and checks for OC ownership, which adds behavioral context beyond the annotations. The annotations already declare readOnlyHint=true (safe read-only operation) and openWorldHint=true, so the description complements rather than contradicts them. It does not detail error handling or side effects, but for a health-check tool this is sufficient.

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, concise sentence that front-loads the core purpose (connection check) and specifies the two key behaviors. Every word earns its place; there is no fluff or redundancy.

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?

For a health-check tool with no parameters and no output schema, the description covers the essential action but omits what the agent should expect as a return value (e.g., success/failure, status message). Given the simplicity, this is a minor gap, but the description could be more helpful by stating the expected output format.

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 zero parameters, so the baseline is 4. The description need not explain parameter semantics; it correctly focuses on the action. Nothing is missing in this dimension.

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 tool's purpose: a connection check that verifies OC ownership and performs one actual round trip to the National Law Information Center OPEN API. It specifies a concrete action and resource, distinguishing it from sibling tools that handle search, body, collect, and citation operations. However, it does not explicitly name or differentiate from siblings, so it falls short of a 5.

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?

There is no guidance on when to use this tool versus the alternatives. The description only states what it does, not the context in which an agent should invoke it (e.g., before other law tools to verify connectivity). No exclusions or alternatives are mentioned, leaving the usage decision entirely to the agent's inference.

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