set_skeletal_mesh_section_visible_in_ray_tracing

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=true, so the safety profile is covered. The description adds the return shape (including a `saved` flag that hints the change is persisted), which is genuinely useful because there is no output schema, but it never explains the destructive/persistence implication, so the added context is modest.

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 sentences with the purpose front-loaded and the return fields listed compactly. Nothing is wasted and the structure is immediately parseable.

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 no output schema and full annotation coverage, the description supplies the missing return-shape information and states the mutation target precisely. It could go one step further and note that the change persists to the asset ('saved'), but it is otherwise sufficient for correct 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?

Schema description coverage is 100%, so the schema already documents all four parameters (b_visible default true, lod_index default 0, section_index default 0, skeletal_mesh_path). The description only echoes 'a specific skeletal mesh LOD' and 'section' without adding format, range, or resolution semantics, so the 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?

The description names a precise verb and resource: toggling the bVisibleInRayTracing flag on a specific section of a specific skeletal mesh LOD. This distinguishes it cleanly from siblings like get_skeletal_mesh_section_info, set_skeletal_mesh_section_cast_shadow, and set_skeletal_mesh_section_recompute_tangent.

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?

Usage is implied by the verb ('Toggle ... on a specific skeletal mesh LOD') but there is no explicit when-to-use guidance, no statement of preconditions, and no reference to read-side siblings such as get_skeletal_mesh_section_info to inspect current state first. An agent can infer intent but gets no routing help.

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