setup_world_sky_texture

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

With no annotations, the description carries the full behavioral burden. It states that the tool configures a procedural sky and that air/dust/ozone apply only to NISHITA, but it does not say whether it replaces existing world setup, whether it is render-engine dependent, what side effects occur, or what happens on success/failure.

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 compact: one purpose sentence followed by a clear Args block. Every line communicates useful information and no filler is present, despite covering seven parameters.

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?

The argument semantics are well covered, but the tool operates in the world environment and has 7 open parameters with no annotations or output schema. The description does not cover what happens with defaults, how this interacts with existing lighting/world nodes, or any prerequisites, so it is only partially complete.

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 this list is the primary parameter documentation. It gives every parameter a meaningful description, units for angles, sky type values, and flags NISHITA-only densities. It does not provide numeric ranges or density units, so it is not a 5.

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 opening sentence names a specific operation ('Set up a procedural sky texture') and a target resource ('world environment'). It is clear this is not HDRI or studio lighting from the word 'procedural', but it never names a sibling or explicitly contrasts with setup_hdri_lighting/setup_studio_lighting.

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 explicit when-to-use guidance, prerequisites, or mention of alternatives. The description implies use for procedural sky environments, but an agent must infer when this is preferred over setup_hdri_lighting, setup_studio_lighting, or set_studio_world.

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