create_object_handle

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

No annotations provided; description only states creation action. Does not disclose behavior if handle already exists, object missing, or any side effects. Leaves agent guessing about idempotency and error handling.

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?

Two short, front-loaded sentences with purpose followed by parameter details. Efficient with no fluff, though could be slightly more compact.

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?

Adequate for a simple creation tool with only 2 parameters. Explains purpose and parameter meanings but omits return value, error conditions, and behavior edge cases.

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 has 0% coverage; description adds meaningful explanations for both parameters: handle (with example names) and object_name (clear reference to Blender object). Adds value beyond schema.

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 states 'Create a handle for an object to reference in future operations' — a specific verb (create) and resource (handle for an object). Clearly distinguishes from siblings like list_object_handles and create_material_handle.

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 context ('easily reference objects across multiple tool calls') but lacks explicit guidance on when not to use or alternatives. No mention of prerequisites or conflicts with other tools.

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