bulk_add_nodes

Add multiple nodes simultaneously to NetworkX graphs while maintaining parent-child relationships for efficient graph construction and management.

Instructions

Add multiple nodes at once (parents before children).

B3/5.0

Behavior2/5

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

No annotations are provided, so the description carries full burden. It mentions 'parents before children', which hints at behavioral constraints, but fails to disclose critical traits like whether this is a mutation (likely yes), permissions needed, error handling, or what happens on failure (e.g., partial updates). This leaves significant gaps for a bulk operation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise with a single sentence that is front-loaded and wastes no words. Every part ('Add multiple nodes at once', 'parents before children') adds value, making it efficient and well-structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (bulk mutation with 2 parameters, no output schema, and 0% schema coverage), the description is incomplete. It lacks details on behavior, parameters, return values, and error handling, which are crucial for a tool that modifies graph data. The minimal guidance is insufficient for safe and effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

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 mentions 'parents before children', which loosely relates to the 'nodes' array parameter but doesn't explain any parameters (graph_id, nodes structure, node_type enum values, etc.). This adds minimal value beyond the schema, failing to address the coverage gap adequately.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Add multiple nodes at once') and resource ('nodes'), making the purpose understandable. It distinguishes from the sibling 'add_node' by emphasizing bulk operations, though it doesn't explicitly mention all siblings like 'bulk_add_edges' for full differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides implied usage guidance with 'parents before children', suggesting a specific order for adding nodes in a graph context. However, it lacks explicit when-to-use vs. alternatives (e.g., 'add_node' for single nodes or 'bulk_add_edges' for edges), and no exclusions or prerequisites are mentioned.

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