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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the agent knows this mutates game state with unpredictable effects. The description adds only the vague notion of an 'allowed' set, saying nothing about what state is changed, whether the two listed commands are the complete set, or how failures surface.

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?

It is a single short clause with no wasted words, and the allowed-set hint is front-loaded. Brevity here shades into under-specification rather than crispness, since the enumerations are unexplained tokens.

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 destructive, non-idempotent action with zero schema documentation and no output schema, the description should explain command semantics and failure modes. It leaves the agent guessing about the meaning and completeness of the accepted values.

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% — the single 'command' parameter is an untyped string with no documentation. The description partially compensates by naming two accepted values, but leaves ambiguous whether that list is exhaustive or what format other commands would take.

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 states a verb ('Run') and resource ('in-game command') and gives two concrete values, which is more specific than a bare name restatement. However, it never explains what '.tvt' or '.novidades' actually do, so an agent cannot tell whether this overlaps with siblings like say, whisper, or status.

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 word 'allowed' hints at a whitelist but gives no when-to-use guidance, no precondition for choosing this over say/whisper, and no statement about what happens with a non-whitelisted command.

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