batch_add_nodes

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

No annotations are present, so the description carries the full burden. It discloses two important behavioral traits: the action is undoable as a single unit, and later entries can reference earlier created nodes as parents. This adds meaningful context beyond the tool name, though it omits error handling and return behavior.

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 concise, two sentences, front-loaded with the primary purpose, and every clause earns its place. No unnecessary information or duplication of schema details.

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?

The tool has moderate complexity with a nested parameter schema, no annotations, and no output schema. The description explains the core behavior and the important parenting quirk, but it does not cover parameter details, potential errors, or what is returned, leaving notable gaps for a batch operation.

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 provides no information about the 'nodes' parameter structure—it does not mention required 'type', optional 'name', 'properties', or 'parent_path'. The description must compensate for the low schema coverage but fails to do so.

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 a specific verb and resource: 'Add several nodes to the edited scene'. It also distinguishes from the sibling 'add_node' by emphasizing the batch nature and the undoable action, making it unique.

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?

It provides context that this is for multiple nodes and that the action is undoable as one unit, implying usage when an atomic batch operation is needed. However, it does not explicitly mention when not to use it or name alternatives like 'add_node' for single-node additions.

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