generate_asset_preset

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It discloses that the output is 'executable' and that time-of-day artifacts are deterministic, which adds some behavioral context. However, it does not mention side effects (e.g., file writes, overwrites), permissions, reversibility, or return behavior. For a generation tool with zero annotation coverage, this is insufficient transparency.

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, focused sentence with no filler words. It front-loads the verb and result, and every phrase ('executable world preset', 'terrain, map, preview, deterministic time-of-day artifacts') adds meaning. No redundant information or promotional language is present.

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 tool has 7 parameters, no output schema, no annotations, and zero schema descriptions. The description lists the artifact types but omits parameter semantics, return format, prerequisites, and any guidance on how the output is delivered (e.g., files, paths). It is too sparse for correct invocation, especially given the complexity of a world preset generator.

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%, meaning the input schema properties have no descriptions, and the tool description must compensate. It does not. The description mentions terrain, map, preview, and time-of-day, but gives no explanation of how parameters like preset_id, output_prefix, width, height, seed, tile_size, or detail_level affect the output. An agent cannot determine the meaning of any parameter from the description alone.

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 clearly states a specific verb ('Generate') and resource ('executable world preset'), and enumerates the artifacts produced (terrain, map, preview, deterministic time-of-day). It does not explicitly name sibling tools, but the scope is distinct enough that an agent can infer what it does. Slight deduction because it does not differentiate from compose_asset_preset or generate_world_map, which are plausible alternatives.

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 usage when a complete world preset with multiple artifacts is needed, but it provides no explicit when-to-use or when-not-to-use guidance, nor does it mention any sibling alternatives. The context signals show many related tools (generate_world_map, compose_asset_preset, generate_day_night_cycle), so the lack of explicit routing is a clear gap. This is adequate but not more than implied usage.

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