capture_channel

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

No annotations are provided, so the description must carry the full behavioral burden. It does not clarify permissions, whether the operation is read-only, what is returned (image data, file path, etc.), or what happens if the channel is missing.

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?

It is a single, front-loaded sentence with no redundant or filler content. The description is concise and easy to scan, even though it omits necessary details 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?

With three parameters, no annotations, no output schema, and zero schema description coverage, the definition is substantially incomplete. It does not explain the return format, the role of texture_set, or the effect of size_log2, so an agent would need to guess.

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 should explain all three parameters. It only gives examples for 'channel' (Roughness, Normal) and does not mention 'texture_set' or 'size_log2', leaving most parameter meaning undocumented.

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 states a specific resource: one flattened channel rendered as a flat texture, with concrete examples (Roughness, Normal). The verb 'See' is a bit vague about whether this returns an image, a file, or a preview, and it does not distinguish itself from siblings like capture_viewport or capture_turntable.

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 no guidance on when to use this tool versus alternatives such as capture_viewport, capture_turntable, or export_textures. The intended context is only implied by the name and the word 'channel'.

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