game_sky

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

No annotations are present, so the description carries full burden. It mentions 'Create/configure' implying mutation but does not disclose side effects, permissions required, or whether existing sky settings are overwritten. The behavioral information is thin.

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 extremely concise (one short sentence) but lacks structure. It front-loads the purpose but omits any elaboration. It is not verbose, but just barely adequate.

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 lack of output schema, no explanation of return values, and no differentiation between 'create' and 'configure' actions, the description is incomplete. It fails to cover the tool's behavior sufficiently for an agent to use it correctly without additional assumptions.

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 coverage is 100% with adequate descriptions for each parameter. The tool description adds no additional context beyond the schema, so baseline 3 is appropriate. No extra semantics are provided.

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 specifies a clear verb ('Create/configure') and resource ('Sky'), and indicates two modes ('procedural/physical'). It is specific enough to distinguish from most sibling tools, though 'Sky' could be more precisely defined (e.g., background sky in a 3D scene).

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?

No information is provided about when to use this tool versus alternatives like game_environment or other environment-related tools. There are no exclusions, prerequisites, or context cues to guide the agent in choosing this tool.

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