set_skeletal_mesh_lod_settings

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

Annotations already declare idempotentHint=true and destructiveHint=true; the description reinforces and clarifies the idempotency by explaining 'Partial update (idempotent): only fields present are written', which is genuinely useful for a mutation tool and tells the agent unspecified fields are left untouched. It does not explain the destructive aspect (why destructiveHint is set) or any permissions/save requirements, so it is good but not complete.

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 tightly written sentences front-load the purpose and scope before the partial-update caveat, followed by a compact return-value line. No filler, though the parenthetical field list is dense.

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?

With eight parameters and no output schema, the description usefully documents the return shape ({lod_index, settings_applied, saved}) and the partial-update semantics, and annotations carry the safety profile. It omits any mention of permission/validation behavior, but for this tool class it is largely complete.

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 schema already documents each parameter (types, units like microns, enum-by-name values). The description's enumeration of covered fields maps to the parameters but adds little beyond what the schema provides; baseline 3 applies.

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?

States a specific verb (set) and resource (flat per-LOD scalars/enums of FSkeletalMeshLODInfo), and explicitly scopes itself as the catch-all for fields 'no other setter covers', enumerating hysteresis, CPU access, morph error tolerance, skin cache usage, mesh deformer, and prioritization weight. This clearly distinguishes it from sibling lod setters like set_skeletal_mesh_lod_build_settings, set_skeletal_mesh_lod_reduction_settings, and set_skeletal_mesh_lod_screen_size.

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 phrase 'no other setter covers' tells the agent when this tool is the right one relative to the many other skeletal-mesh lod setters, which is meaningful routing guidance. It stops short of naming the specific alternative setters or stating explicit exclusions, so it is clear context rather than full when/when-not guidance.

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