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

The annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds useful scope by naming the settings affected, but does not explain partial-update behavior, whether omitted fields are preserved, or how input gain snaps to hardware steps.

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?

It is a single, front-loaded sentence fragment with no wasted words. The terseness is appropriate for a catalog-style description, though it leaves important operational details unstated.

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 moderate-complexity tool with four parameters, a nested EQ object, and no required parameters, the description covers the field scope but omits important semantics. It does not explain whether this is a merge or replace operation, and it gives no guidance on the individual EQ bands beyond saying there are four.

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 50%, with descriptions present for tempo_sync and input_gain_db but not for the nested EQ object. The description compensates somewhat by mapping all four top-level parameters to their meaning, including 'global EQ (4 bands)' and 'where the delay tempo comes from,' though it adds no detail on individual EQ band fields.

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 identifies the resource and enumerates the specific settings it covers: CabSim, input gain, global EQ, and delay tempo source. It is clearly a settings mutation tool, though it does not explicitly distinguish itself from siblings such as set_mixer or set_system_byte.

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 explicit guidance on when to use this tool versus get_settings, set_mixer, or set_system_byte. Usage is only implied by the phrase 'Global settings,' leaving the agent to infer the appropriate context and exclusions.

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