layout_node_tree

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

With no annotations, the description carries the full burden of disclosing behavioral traits. It only states the action; it does not mention that this modifies node positions, whether it overwrites custom layouts, or any side effects. This is a mutation tool, and the lack of detail 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?

The description is a single, efficient sentence that directly states the core functionality. It is front-loaded and free of fluff, though it achieves conciseness by omitting necessary context.

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 lack of annotations, minimal parameter info, and the potentially destructive nature of auto-arranging, the description is incomplete. It does not mention side effects, required material identification, or any caveats, making it inadequate for safe and correct usage.

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%, and the description does not elaborate on the 'material' parameter. It fails to explain how to specify the material (e.g., by name or ID) or any constraints, leaving the single parameter ambiguous.

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 'Auto-arrange nodes in a material's node tree' clearly states the action (auto-arrange) and the resource (nodes in a material's node tree). It is specific and distinct from sibling tools like create_shader_node or connect_shader_nodes, though it does not explicitly name alternatives.

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 about when to use this tool versus alternatives. It does not mention scenarios, prerequisites, or contrast with other node layout/selection tools, leaving the agent without context for appropriate invocation.

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