set_node_color

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

With no annotations, the description carries the full behavioral burden and delivers almost nothing: it doesn't say whether the change is persisted with the scene, whether it's reversible, what happens if node_path is invalid, or what the response looks like. It does at least communicate that the effect is a UI/editor-level color change rather than a render property.

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?

A single front-loaded sentence with no filler. It is efficient, though its brevity is also the source of the missing information noted elsewhere.

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 four-parameter mutation tool with no annotations, no parameter descriptions, and no output schema, this is under-specified. An agent needs at minimum the RGB value range and node path conventions before calling it correctly.

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% across four required parameters, and the description adds no meaning. Critically, the expected range for r/g/b (0-1 floats vs 0-255 ints) and the path format/root convention for node_path are left entirely to guesswork, which is a real risk of failed or wrong calls.

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?

Specific verb + resource ("Set a node's color") with a scoping qualifier, "in the network editor," which signals this is visual tinting rather than render/material color. That distinguishes it reasonably from siblings like set_node_flags or set_node_position, though it never names them explicitly.

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?

There is no when-to-use or when-not-to-use guidance at all. The agent gets no hint about when to prefer this over set_node_flags (which may also affect node appearance) or whether it applies to the current network only.

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