game_skeleton_ik

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

Annotations are sparse (only title), so the description must disclose side effects and behavioral traits. It only lists actions without mentioning what starting or stopping IK entails, required node setup, or potential modifications to the skeleton. The tool's behavior beyond the basic actions is opaque.

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 extremely short and to the point, with no superfluous text. However, it might be too terse for a tool with three parameters and nested objects, but it still earns a high score for minimalism.

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?

Given the tool's complexity (3 parameters, one nested object), the description lacks details on return values, error conditions, or the effects of repeated actions. The high schema coverage does not fully compensate for the missing behavioral and contextual information.

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 100% with clear descriptions for all three parameters. The description adds little beyond the schema; it merely echoes the action names. With high schema coverage, baseline is 3, and the description does not significantly enhance understanding.

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 it's for SkeletonIK3D and lists the actions 'start/stop/set target position', which is specific. However, it does not differentiate from sibling tools like game_bone_pose or other animation tools, missing a chance to clarify its unique role.

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 provided on when to use this tool versus alternatives, nor any conditions or prerequisites. The description is purely imperative, leaving the agent to infer usage context.

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