loop_cut

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

No annotations provided, yet the description does not disclose behavioral traits beyond 'Add loop cuts'. It fails to mention if the operation is destructive, requires edit mode, or other side effects.

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 very concise with a clear structure: a one-sentence summary, then Args and Returns sections. No extraneous words.

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?

For a simple two-parameter tool with an output schema, the description is fairly complete. It mentions the return type (confirmation dict). However, it could clarify prerequisites (e.g., object must be a mesh) or error behavior.

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?

The input schema has 0% description coverage, so the description adds crucial meaning: it explains that 'object_name' is the mesh object and 'cuts' has a range of 1-100. This goes beyond schema titles and types.

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 states 'Add loop cuts to a mesh object' which is a specific verb-resource pair. Among siblings like subdivide_mesh and bevel_edges, loop cut is distinct and clearly identified.

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 guidance on when to use this tool versus alternatives (e.g., subdivide_mesh). The description only says what it does, not when or when not to use it.

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