set_skeletal_mesh_allow_cpu_access

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

Annotations already declare destructiveHint=true and idempotentHint=true, plus the description discloses the scope (every LOD) and the memory-residency consequence of the flag. However, it never explains what the destructive aspect actually costs (increased memory footprint) or that changes are persisted, beyond the return field 'saved'.

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?

Purpose and effect are front-loaded in the first sentence, followed by a use rationale and an inline return shape. It is efficient and free of filler, though the inline return spec could be moved to an output schema.

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 two-parameter setter, the description covers purpose, when it matters, and the return payload, while annotations carry the safety profile. It is nearly complete; the only gap is not clarifying the memory cost implied by the destructive hint.

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 coverage is 100% and both parameters are already documented, including b_allow's default of true. The description adds only that the value is applied across all LODs rather than one, which is minor added meaning over the 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?

States a specific verb (Set) and resource (bAllowCPUAccess on every LOD of a skeletal mesh), plus the effect (keeping vertex/skin data resident). An agent can distinguish it from the many other set_skeletal_mesh_* siblings, which target LOD settings, sockets, or materials rather than CPU access.

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?

It gives a clear use context ('for FX sampling or other CPU work'), which tells the agent when this flag is relevant. It stops short of naming when NOT to use it or pointing to an alternative tool, so it does not reach a 5.

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