remove_color_ramp_element

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

No annotations are provided, so the description must convey behavioral traits. It warns about the failure on removing the last stop, which is useful. However, it does not disclose other potential side effects, such as whether the operation is destructive or if it requires specific permissions. The return values are described but are covered by the output schema.

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: a one-sentence purpose, a constraint, then a structured Args/Returns section. No redundant information. Slightly more detail could be added without harming conciseness.

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?

Given the tool's simplicity and the presence of an output schema, the description covers the essential aspects: action, constraint, parameter meanings, and return information. It lacks only minor contextual details like prerequisites or node type requirements.

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?

The input schema has 0% description coverage, so the description's 'Args' section adds critical meaning. It explains each parameter: material_name, node_name, and index (noting zero-based). This provides clarity beyond the raw schema.

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 the action ('Remove a colour stop from a ColorRamp node') with a specific verb and resource. It distinguishes this tool from sibling tools like 'add_color_ramp_element' and 'set_color_ramp_element' by focusing on removal.

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?

The description includes a key constraint ('Blender requires at least one stop to remain; removing the last one fails'), but does not provide explicit guidance on when to use this tool versus alternatives or any prerequisites (e.g., existence of a ColorRamp node). Implied usage is present but not thorough.

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