explore

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 doesn't disclose whether this is a read-only observation or a write/state-changing action, what happens during 'exploration' (movement? chunk loading? scanning?), whether it terminates, or any side effects. For a tool with a sibling set full of movement and mining commands, this is a significant gap.

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?

A single, short sentence with the core information front-loaded. It wastes no words, though brevity here borders on under-specification rather than true conciseness.

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 an output schema present, return-value explanation isn't needed, but the description still fails to cover basic invocation semantics (required params vs. the 'if omitted' claim), behavioral nature (read vs. write, movement vs. inspection), or differentiation from many movement/search siblings. Incomplete for a tool in a densely populated namespace.

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 0% — the integer x,z parameters have no titles or descriptions in the schema. The description mentions 'the origin of x,z' and 'player feet if omitted', which hints at semantics, but this is contradicted by both parameters being marked required. An agent cannot determine coordinate conventions, allowed ranges, or nullability behavior.

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 ('Explore') and a resource/domain ('the world from the origin of x,z'), which is clearer than a bare restatement of the name. However, it's vague about what 'explore' operationally means — no indication of whether it's a movement/wander behavior, a scanning operation, or a search. Against siblings like 'path', 'goto_block_type', and 'find', it's not sufficiently differentiated.

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?

There is no explicit guidance on when to use this tool versus alternatives like 'find', 'path', or 'goto_block_type'. The parenthetical 'or player feet if omitted' implies usage context but the required 'x','z' parameters (both required) contradict the 'if omitted' phrasing, leaving an agent confused about invocation conditions.

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