add_group_socket

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

With no annotations, the description carries the burden of explaining side effects. It conveys that the tool modifies a node group by adding a socket, which is clear, but it does not mention potential side effects, dependencies, or the impact on existing sockets.

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 brief and to the point, consisting of one action sentence and a socket type example list. It is well-structured and easy to parse, though the socket types could be formatted more clearly.

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 5 parameters and 2 required, the description does not fully cover the tool's usage context. It omits explanations for key parameters like in_out and default, and with no output schema, the agent is left without essential operational details.

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%, so the description must compensate. It only explains socket_type by listing possible values, leaving name, in_out, default, and node_group entirely undocumented. This is insufficient for a multi-parameter tool.

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 specific verb ('add') and resource ('socket to node group interface'), and clarifies the purpose of exposing it to the modifier panel. It does not explicitly name sibling tools, but the action is unambiguous.

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 provides no explicit guidance on when to use this tool versus alternatives. It mentions exposing to the modifier panel, which gives some context, but does not state conditions or contrast with related operations like adding geometry nodes.

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