set_sound_concurrency_properties

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

Annotations already declare write/destructive/idempotent status, so the bar is lower, and the description adds real behavior: it is a partial merge (not a full replace) and values are clamped rather than rejected, which tells the agent out-of-range input is silently coerced. It does not explain permissions or what state the destructive hint affects, but it meaningfully extends the safety profile.

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 sentences, front-loaded with the action and followed by an explicit return contract. Both lines earn their place, especially the return shape given there is no output schema. Minimal but not wasteful.

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, the description supplies the return contract (applied_keys, saved, etc.), filling a real gap, and annotations cover the safety profile. Only edge behavior for an invalid concurrency_path and why the operation is destructive are left implicit, which are minor for a 2-parameter setter.

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% and the settings object already enumerates every field with types and ranges, so the schema carries the load. The description only echoes merge semantics already stated in the schema ('absent keys untouched') and adds the clamp behavior, so baseline 3 is appropriate.

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 and resource: authoring FSoundConcurrencySettings on a USoundConcurrency, with the mechanism (reflection) and semantics (partial merge + clamp) named. It is distinguishable from read siblings like get_sound_concurrency_properties, but it never explicitly contrasts itself with create_sound_concurrency or the broader set_sound_*_properties family.

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?

There is no when-to-use, when-not-to-use, or prerequisite guidance. The agent is not told to read current settings first (e.g., via get_sound_concurrency_properties) or when this differs from create_sound_concurrency. Usage is only implied by the verb and resource.

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