add_normalize_vector_node

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

With no annotations, the description carries the burden of behavioral disclosure. It clearly states the action (adds a node) and the node's output semantics (unit vector), but it does not explicitly describe tool-level side effects such as modifying the Blueprint graph or clarify that the "returns" phrasing refers to the node rather than the tool itself.

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 front-loaded with the core purpose, then organized into Args, KB reference, and Example. The Ch.14 educational line adds context but is slightly extraneous; overall the structure is clean and scannable.

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?

For a simple two-parameter tool with an output schema, it covers purpose, mathematical behavior, usage, parameter semantics, and an example. It does not state prerequisites like an existing loaded Blueprint, but the example and parameter guidance are sufficient for typical 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%, so the description must compensate for parameter meaning. It provides an Args block explaining blueprint_name and node_position, including that node_position is optional and is an [X, Y] graph position, plus a concrete example path. This adds meaningful guidance beyond the bare schema titles.

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 starts with a specific verb and resource: "Add a 'Normalize' vector node" and clarifies the node's function as producing a unit vector with length 1. This clearly distinguishes it from the many other add_*_node siblings by naming the exact node type and its mathematical behavior.

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 gives a concrete usage context: "Used before multiplying by speed to get direction-based movement." This tells an agent when the tool is appropriate, though it does not explicitly state alternatives or when not to use it.

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