set_gamerule

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It merely states 'set' without elaborating on effects (e.g., immediate vs persistent change), any prerequisites, side effects, or whether the server must be running. This is a severe gap for a mutating 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?

The description is a single sentence with no wasted words, but it is under-specified. It is front-loaded with the action, but lacking necessary detail for an agent to use it effectively, so the size is not appropriate for the complexity of the operation.

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 mutation tool with zero annotations und an empty output schema, the description burdens the agent with all context. It fails to state what rules are available, what value formats are accepted (e.g., booleans, numbers), prerequisites like a running server, or side effects. This is severely inadequate.

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 0%, and the description provides zero explanation of what 'rule' or 'value' should contain. The agent gets no information about valid rule names or value formats, so it would have to guess or rely on external knowledge.

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: setting a gamerule on the server. However, it doesn't differentiate from siblings like server_properties_set, which also modifies server settings, though gamerule is a distinct concept. The verb and resource are specific enough to convey the core purpose.

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 given on when to use this tool versus alternatives. It doesn't mention what gamerules are applicable, whether the server needs to be running, or any exclusions. The user must infer usage from the name alone.

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