armorpaint_set_layer_channels

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

The description names the enable/disable action but does not explain the crucial behavior of null versus boolean values, whether existing channel data is preserved or replaced, or what happens when no channels are specified. Annotations provide only generic false hints, so the description carries the transparency burden but leaves important behavioral semantics unexplained.

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 a single front-loaded sentence with no wasted words. The verb and object appear immediately, and the rest of the sentence adds relevant scope without filler.

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 eight parameters and a dense sibling set, the one-sentence description is incomplete. It does not explain null semantics, layer selection context, or how to relate this to the surrounding layer and material tools. The output schema exists, so return-value details are less critical, but setup and operational context are still missing.

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 the eight undocumented parameters. It groups the booleans conceptually as 'PBR channels' but does not map them to base_color, roughness, metallic, etc., nor does it clarify the meaning of null for optional channels or the role of layer_id.

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 uses a specific verb ('Enable or disable') and a clear resource ('individual PBR channels on a paint or fill layer'), so an agent can tell this is a layer-channel configuration tool. It does not explicitly contrast with sibling tools such as armorpaint_set_layer or armorpaint_set_material_pbr, but the channel-focused language is reasonably distinctive.

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 guidance on when to use this tool instead of related siblings like armorpaint_set_layer, armorpaint_set_material_pbr, or armorpaint_fill_layer. No prerequisites, such as requiring an existing layer or a selected layer, are mentioned.

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