create_object_state

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

No annotations are provided, so the description carries full burden. It says 'edit it with a text description' but does not clarify whether the original object is modified, what side effects occur, or what permissions are needed. The creation of a new state could imply mutation, which is not disclosed.

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 an inline example, achieving conciseness. However, it could be slightly more structured (e.g., separating the example) without losing efficiency.

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?

The description does not explain the return value or output format, which is critical since there is no output schema. It also omits constraints like whether the source object must exist or what types of objects are valid. For a tool with three parameters, this lack of detail leaves significant gaps.

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%, providing descriptions for all parameters. The tool description adds value by giving concrete examples ('open chest', 'broken') for the 'edit_description' parameter, clarifying the expected input format beyond the schema.

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 verb 'create', the resource 'state/variant of an existing object', and the method 'by editing it with a text description'. It distinguishes from sibling tools like 'create_character_state' by specifying 'object'.

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 a prerequisite ('Requires a source object_id') but provides no guidance on when to use this tool versus alternatives such as 'create_object_1dir' or 'animate_object'. It does not explain scenarios or exclusions.

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