mixer_set_eq_band

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

Annotations are absent, so the description carries the behavioral burden. It does disclose allowed ranges and normalization for gain and frequency, which is useful, but it does not explain what null gain/frequency means, whether omitted values leave the band unchanged, or what happens to the existing EQ state after the call.

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?

A single, tightly worded sentence conveys the action and all critical value constraints with no filler. The most important scoping information, 'set one band of the mixer EQ,' is front-loaded.

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 simple setter with no output schema, the description is mostly adequate, but it leaves two operational gaps: the meaning/semantics of null-valued gain and frequency is unstated, and the 'track' parameter is not explained. These gaps matter more because no annotations or schema descriptions exist to fill them.

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 0%, so the description must add meaning itself. It does so effectively by mapping band=0|1|2 to low/mid/high and by giving explicit numeric ranges for gain and frequency. However, the required 'track' parameter is left undocumented in both the schema and description.

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 opens with 'Set one band of the mixer EQ,' a specific verb plus a clearly bounded resource. It also disambiguates from the sibling mixer_get_eq by emphasizing the write operation and from other mixer_set_* tools by targeting a single EQ band.

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?

No guidance is given about when to use this tool versus related mixer tools, such as mixer_get_eq, mixer_set_volume, or mixer_set_pan. The usage context is only implied by the name and brief description rather than explicitly stated.

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