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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds useful behavioral context by enumerating the returned descriptor sections, including connectability with auth/health and trust breakdown. It does not cover error cases, but for a read-only getter this is a minor gap.

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?

One dense, front-loaded sentence that leads with the primary output ('Official server.json') and then lists additional sections in a compact parenthetical list. No filler or redundant phrasing.

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?

Given no output schema, the description does a good job of listing the main sections returned by the tool. It omits explicit error behavior and a precise return shape, but with a single required string parameter and read-only annotations, the remaining gaps are minor.

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?

Schema description coverage is 100%, so the baseline is 3. The description's 'server name' matches the `name` parameter and 'current tools' loosely maps to `schemas`, but it adds no parameter format, constraints, defaults, or behavior beyond what the schema already documents.

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?

Description states a specific verb and resource: getting the full server descriptor for one named server, and enumerates what is included (server.json, connectability, tools, trust breakdown, identity). It is clear and distinct from siblings in scope, though it does not explicitly name a sibling to differentiate from.

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 description implies when to use this tool: when you need the official server descriptor, connectability details, tools, trust, and identity for a single server. However, it does not explicitly state when to prefer get_connection, search, or list_tools instead, aside from the schema hint that full schemas belong with list_tools.

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