gen_capture_texture_paint_snapshot

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'capture' and gives an example; it does not mention that the tool writes screenshot files to screenshot_dir, may upload results to Tripo when upload_to_tripo is true, or otherwise affects external systems. This is a meaningful transparency gap.

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 appropriately brief: a single purpose sentence, a KB pointer, and a compact example. It is front-loaded with the core action and does not waste words, though the KB pointer is terse and assumes the agent can resolve the internal link.

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 tool with 7 optional parameters, no annotation safety profile, and meaningful side effects (file output and optional external upload), the description is incomplete. It does not explain return values, output location, upload behavior, or when a Texture/Paint session must already be active. The KB pointer helps but does not fill these gaps inline.

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, but it only illustrates three parameters (session_name, label, upload_to_tripo) in an example without explaining their meaning, constraints, or interplay. Parameter names are somewhat self-explanatory, but the description adds little semantic value beyond the schema's raw names and defaults.

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 concrete action ('Capture the active Unreal viewport') and scopes it to a Texture/Paint session, which makes the tool's purpose immediately identifiable. It does not explicitly distinguish itself from generic siblings like take_screenshot or viewport_capture_screenshot, but the Texture/Paint scoping provides enough differentiation.

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 implies this is for Texture/Paint session workflows but gives no explicit guidance on when to use it versus generic screenshot tools or alternate capture methods. No exclusions, prerequisites, or alternative tool recommendations are provided, leaving the agent to infer usage context.

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