blender_iso_build_room

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 mentions that the tool 'builds' and 'exports', but does not disclose side effects such as file creation, scene mutation, Blender session requirements, or whether existing data is overwritten. The description is more of a feature list than a behavioral contract.

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 sentence that front-loads the main action, but it is dense with promotional adjectives like 'production-grade' and '50+ avatar capacity', which add bulk without clarifying tool behavior. It is not poorly structured, but it could be more concise and better organized into key behavior versus output details.

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?

This is a complex tool with 9 parameters, nested objects, no output schema, and no annotations, yet the description provides only a high-level feature summary. An agent would not know what the parameters mean, what the output looks like, what side effects occur, or what inputs are required, making the description inadequate for correct invocation.

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 for 9 undocumented parameters, but it does not explicitly explain depth, width, palette, tileSize, furniture, floorStyle, wallHeight, renderOutput, or resolutionWidth. The high-level phrases like 'fine-density tiles' and 'ergonomic furniture' only loosely hint at a couple of parameters and provide no actionable mapping.

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 uses a specific verb ('builds') and a specific resource ('virtual avatar lounge'), and adds concrete characteristics like '2:1 dimetric isometric' and 'exports for web game frameworks'. This clearly distinguishes it from sibling tools such as blender_iso_create_tile and blender_iso_setup_scene, which target narrower or different resources.

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 gives no explicit guidance on when to use this tool versus alternatives, and does not mention any exclusions or prerequisites. It only implies usage by describing what the tool builds, leaving the agent to infer the appropriate context from the tool name and sibling list.

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