add_flipflop_node

Adds a Flip Flop node to a Blueprint that alternates between A and B outputs on successive calls, with an IsA boolean output.

Instructions

Add a Flip Flop node that alternates between A and B outputs.

On the first call it executes 'A', on the second call 'B', then back to 'A', etc. Also provides 'IsA' boolean output.

Args: blueprint_name: Blueprint name node_position: Optional [X, Y] graph position

KB: see knowledge_base/01_BLUEPRINT_FUNDAMENTALS.md#overview Example: add_flipflop_node(blueprint_name="/Game/MCP_Test/BP_Example")

A3.5/5.0
Behavior4/5

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It clearly explains the node's runtime alternation pattern, the IsA boolean output, and includes a concrete example. It does not discuss side effects on the blueprint asset or persistence, but the core behavior is unusually well disclosed.

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

Conciseness4/5

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

The description is well-organized and front-loaded with the most important behavioral details, followed by arguments, a KB pointer, and an example. It is compact with no filler, though the KB reference and example could arguably be merged without loss.

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

Completeness4/5

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

For a two-parameter tool with an output schema, the description covers the node's purpose, behavior, parameters, and provides an example call. It is reasonably complete, but it misses guidance on where the node is placed within the blueprint and how this tool relates to the sibling add_blueprint_flip_flop_node.

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

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must add meaning to the parameters. It provides brief human-readable explanations for blueprint_name and node_position, plus an example showing the expected blueprint path format. This is helpful but shallow: node_position syntax is only loosely described as '[X, Y] graph position' without units or coordinate details.

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 states a specific verb ('Add'), a clear resource (Flip Flop node), and explains the alternating A/B behavior and IsA output. However, it does not differentiate itself from the sibling tool add_blueprint_flip_flop_node, which appears to target the same node type.

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

Usage Guidelines2/5

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

The description implies when to use the tool but provides no explicit guidance about when to choose this over alternatives, nor any context about graph selection or preconditions. With many sibling add_*_node tools, the lack of any exclusion or alternative hint is a meaningful gap.

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