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

No annotations are provided, so the description carries the full disclosure burden. It does convey that the tool is non-mutating and informational via the verb 'Explain' and tightly constrains the content to five governance aspects. It does not, however, disclose output form, depth, or whether the explanation is static or generated, leaving some behavioral ambiguity 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?

A single sentence that front-loads the action and resource, then uses a colon to introduce a tight list of the five covered topics. There is no fluff, and every word contributes to scoping the tool's behavior.

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 informational tool with no output schema, the description is nearly complete: it specifies exactly which aspects the explanation should cover, which is enough for an agent to invoke it correctly. The only minor gap is that the response format is not described, but 'Explain' strongly implies prose, so this is a small omission.

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 input schema is empty with additionalProperties set to false, so there are zero parameters to document. Per the baseline for zero-parameter tools, this dimension is satisfied; the description has no parameter burden to carry.

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 uses a specific verb ('Explain') and a precise resource ('the server's governance-first design'), then enumerates five concrete subtopics: delegated auth, least privilege, auditing, oversharing/sensitivity awareness, and local-only operation. This makes the purpose unmistakable even against siblings 'search' and 'about', though it stops short of explicitly contrasting itself with those siblings.

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 versus when-not-to-use guidance or named alternatives. However, the enumerated governance topics make the intended invocation context inferable: an agent can reasonably choose this tool when a user asks about the server's auth, privilege, audit, or privacy design. This is implied usage rather than stated guidance.

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