blender_mesh_loop_cut

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

No annotations are provided, so the description carries the behavioral disclosure burden. It conveys that the operation is additive and localized, but it does not state whether the mesh is modified in place, what prerequisites exist (e.g., a valid edge index), or what happens on failure.

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 two short sentences with no filler. The core action and key differentiator are front-loaded, making it easy for an agent to parse quickly.

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 there are no annotations and no output schema, the description is somewhat thin. It explains the purpose and differentiates from whole-mesh subdivision, but omits practical details like how to identify a valid edge_index, whether the operation requires a specific object mode, and what the expected result or return value is.

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 100%, so the input schema already documents every parameter. The description adds only thematic context ('specific areas') and does not deepen understanding of edge_index, cuts, or smoothness beyond what the schema provides.

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 identifies the verb and resource: adding edge loops to a mesh. It also explains the intended use ('topology control') and contrasts with subdividing the whole mesh, which helps distinguish it from sibling tools like blender_mesh_subdivide.

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 clear context: use this for targeted topology resolution in specific areas rather than whole-mesh subdivision. It implies the alternative but does not explicitly name it or state when not to use the tool, so it stops short of a 5.

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