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

There are no annotations provided, so the description must disclose behavioral traits itself. It only restates the action without mentioning side effects (e.g., whether it establishes a persistent session), authentication flow, error handling, or whether it disrupts an existing connection. This leaves significant behavioral gaps for an agent to navigate.

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, front-loaded sentence with no filler or repetition. Every word contributes to the core meaning, making it highly concise and structured effectively.

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?

With no annotations, no output schema, and a mutating/connecting action, the description should explain expected behavior such as whether the connection is maintained, what happens on timeout, or if it invalidates previous sessions. The current description is too shallow for an agent to fully complete the task reliably in a complex environment.

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 adds a small nuance by calling the API key an 'identifier,' implying a dual role beyond simple authentication, but it does not clarify how parameters relate to each other or what values are valid. This is just enough to justify a baseline score.

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 action ('Connect') and the resource ('a Minecraft server'), using a specific verb that distinguishes it from the sibling 'disconnect' tool. However, the phrase 'using API key as identifier' is slightly ambiguous—it could imply the API key identifies the server or the user, which prevents a perfect score.

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?

No guidance is provided on when to use this tool versus alternatives, when it should be called (e.g., before other commands), or what prerequisites exist. The sibling tools like 'list_servers' and 'disconnect' suggest a workflow, but the description does not mention them or any situational context.

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