B3.1/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden, and it does not state that this is a mutation, whether the change is persisted (a separate wwise_save call may be required), what permissions are needed, or what happens on invalid property names or values. The only behavioral hint is the value encoding note, which is closer to parameter semantics.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The one-line summary is front-loaded and the Args block is compact with no filler. It is appropriately sized for a three-parameter setter, though the param list is a restatement of the schema keys padded with per-line labels.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be described, and all three parameters are covered. What is missing for a mutation tool with no annotations is the operational context: connection state, save/persistence requirement, and failure behavior, which an agent needs before calling this in a workflow.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, and it does: it explains each of the three params, gives example property names (Volume, Pitch, Lowpass, IsLoopingEnabled), and clarifies that value is JSON-encoded rather than a raw literal. It falls short of enumerating valid property names or the accepted object_path format (path vs GUID examples).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('Set a property on a Wwise object'), which is clear and actionable. However, it does not distinguish itself from close siblings such as wwise_set_reference, wwise_set_attenuation, or wwise_create_game_parameter, so an agent must infer which setter applies from the parameter names alone.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives. The description says nothing about needing an active WAAPI connection (cf. wwise_connect), whether the target object must already exist, or when to prefer this over the more generic execute_waapi.

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