apply_geometry_nodes

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

With no annotations provided, the description must carry the full burden of behavioral disclosure. It does not mention side effects, requirements (e.g., whether the modifier must exist), or consequences (e.g., whether the modifier is removed after applying). The description simply restates the action without revealing operational details.

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 with no wasted words, which is concise. However, it achieves brevity by omitting essential details, so it is structurally simple but under-informative.

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?

This is a mutation tool with no annotations, an output schema, and a 0% descriptor coverage in the schema. The description is critically incomplete: it fails to clarify object targeting, modifier existence, expected output, or error conditions. Given the many related geometry nodes operations, the description is inadequate for safe invocation.

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 adds no parameter information. object_name and modifier_name are not explained; the default null for modifier_name is left ambiguous. The description fails to compensate for the sparse schema, leaving agents without necessary semantics.

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 clear verb and resource: 'Apply a Geometry Nodes modifier on an object.' It is distinct from the generic apply_modifier sibling by specifying geometry nodes, so an agent can identify the tool's purpose. However, it does not elaborate on what 'apply' entails (e.g., finalizing vs. baking), which slightly limits clarity.

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 guidance on when to use this tool versus alternatives like apply_modifier or create_geometry_nodes_modifier. No context, prerequisites, or exclusions are provided, leaving the agent to infer usage without supporting information.

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