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

No annotations are provided, so the description carries the full burden. It discloses the two actions and the prerequisite for 'set', but does not describe return values, side effects, or behavior when setting multiple times. Without an output schema, the agent lacks information on what 'list' returns.

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 short and directly states the purpose followed by a bullet list of actions. It is front-loaded with the overall goal and efficiently conveys the core functionality without extraneous text.

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 tool with two actions and two parameters, the description is mostly adequate but lacks return value details and prerequisites like needing to connect first (suggested by sibling 'mc_connect'). Without an output schema, the description should have explained what each action returns.

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 coverage is 100% with descriptions for both parameters. The tool description adds minimal value beyond the schema—it repeats the action enum and version example. Since the schema already documents the parameters clearly, the description does not significantly enhance understanding.

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 it manages Minecraft versions for static analysis tools, with two actions 'set' and 'list' that define the resource and verb. The context distinguishes it from sibling tools which deal with blocks, entities, screenshots, etc.

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 mentions that 'set' is required before using other static tools, giving a clear usage context. However, it does not provide explicit when-not-to-use or alternatives among siblings, leaving some ambiguity about when to use 'list' versus other tools.

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