create_object_1dir

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

No annotations provided, so description carries full burden. Clearly indicates creation, persistence, single-direction, and the effect of size on multiplicity. Lacks explicit mention of return values or error handling, but sufficient for a creation tool.

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?

Concise, front-loaded with purpose, followed by parameter details and sibling comparisons. Every sentence adds value with no redundancy.

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 5 parameters (1 required), no output schema, and no annotations, the description thoroughly covers tool purpose, parameter intricacies, and usage context with sibling tools. Complete enough for effective selection and 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?

Adds meaningful context beyond schema: size range and default, view enum values, optional style_images, and the warning about multiple objects with item_descriptions. Schema already covers all parameters, but description clarifies behavior.

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?

Description explicitly states verb 'Create' and resource 'persistent single-direction object', and distinguishes from siblings 'create_object_8dir' and 'create_map_object'.

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?

Provides alternatives: 'For an object rotatable to 8 directions use create_object_8dir. For single-view non-persistent props use create_map_object.' Also gives defaults and conditions like size range and view options.

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