minecraft_status

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

With no annotations, the description carries the full burden. The verb 'Observe' does imply a read-only, non-mutating operation, which is useful. However, it does not clarify whether the result is a one-time snapshot, whether a connection to the game is required, or any other behavioral traits beyond the list of observed data.

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 filler, front-loading the action 'Observe' and then efficiently listing the observed data. Every word contributes to understanding the tool.

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 zero-parameter status tool with no output schema, the description enumerates all the relevant data categories. It could be slightly more complete by explicitly stating that it returns the current snapshot, but the listed content is enough for an agent to know what to expect from a simple status read.

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?

The tool has zero parameters and 100% schema coverage with an empty properties object, so there is nothing for the description to add about parameters. The baseline of 4 for zero-parameter tools applies.

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 uses a specific verb ('Observe') and names concrete resources: health, position, weather, gaze target, and nearby entities. This clearly sets it apart from siblings like minecraft_inventory (items) and minecraft_events (streams), making its purpose unambiguous.

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 gives no explicit guidance on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or that it should be preferred over minecraft_events for a current-state snapshot. Usage is only vaguely implied by the word 'Observe'.

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