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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the response is short and cacheable, but it does not explicitly state that the operation is read-only, what permissions are needed, or what the response shape is beyond high-level categories.

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 compact fragments, front-loaded with the returned content categories and followed by a useful caching note. No sentence is wasted, though the terseness is only acceptable because the tool is simple and parameterless.

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 zero-parameter tool with no output schema, the description names the categories of data returned and characterizes the response as structured, short, and cacheable. That is enough to set expectations, even if it does not describe the exact return structure.

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 there are no parameter semantics for the description to explain. The baseline score for a parameterless tool applies.

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 enumerates the resource returned: capabilities, limits, scopes, languages, and available tools. That makes the tool's purpose clear, though it is a noun phrase without an explicit verb and does not distinguish it from siblings such as discover_lahze.

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 explicit when-to-use guidance and no alternatives are named. 'Short and cacheable' hints at repeated or cached use, but it does not tell an agent when to choose this over discover_lahze or get_connection_status.

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