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

With no annotations provided, the description partially carries the behavioral burden by stating that the check is unauthenticated and targets LEVEA_API_URL. It does not explicitly state that the operation is read-only, what it returns, or whether it has any side effects, leaving gaps for a no-annotation tool.

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?

Two short sentences deliver the key facts: what the diagnostic checks, the target endpoint, and the authentication expectation. There is no wasted text and the core purpose is front-loaded.

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 simple health-check tool this is minimally adequate: it identifies the endpoint and unauthenticated nature. However, because there is no output schema and no annotations, the description should ideally say what a successful or failed diagnosis returns or how failures surface.

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 takes zero parameters and the schema is empty, so there are no parameter semantics to document. The description introduces no misleading parameter information, and the baseline for zero-parameter tools is appropriately met.

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 states a specific diagnostic purpose against a named endpoint (LEVEA_API_URL), so an agent can tell this is a health/connectivity check rather than an editing or asset operation. It does not explicitly differentiate itself from the many sibling tools, but no sibling provides a health diagnostic.

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 phrase 'Connectivity diagnostic' implies when to use it: checking whether the editor API is reachable. However, the description gives no explicit when-to-use guidance, prerequisites, or alternatives, so the usage condition is inferred rather than stated.

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