godot_configure_physics_joint

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

The annotations indicate that the tool is not read-only, not idempotent, and not destructive, but the description carries the burden of explaining the actual mutation behavior. It says joints are 'created and configured', but does not disclose that a joint node is likely added to the scene tree and bound to two physics bodies.

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, scannable sentence with no filler. It front-loads the main purpose and enumerates types efficiently, though it is so short that it leaves out guidance that would increase usefulness.

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?

Despite the detailed input schema and output schema, the description is too thin to route an agent among dozens of godot_* siblings. It fails to mention 2D joint support, the requirement for two body node paths, effect on the scene tree, or when this tool is the right choice compared with node mutation utilities.

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 description gives human-readable joint names that map loosely to joint_type values, but it exposes none of the eight parameters that affect invocation, such as node_a_path, node_b_path, position, rotation, and parameters. The '3D' qualifier also conflicts with the schema's supported 2D joint types like pin_2d, groove_2d, and damped_spring_2d.

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 clear verb-resource combination, 'create and configure physics joints', and lists the main 3D joint types (Pin, Hinge, Slider, ConeTwist, 6DOF). It does not explicitly differentiate itself from generic scene-construction tools like godot_create_node or godot_modify_node, and the '3D' qualifier omits the 2D joint types supported by the schema.

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 when-to-use or when-not-to-use guidance is provided. The description does not mention prerequisites such as existing node_a/node_b physics bodies, nor does it clarify when this tool should be preferred over manually creating or modifying joint nodes via other sibling tools.

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