set_macro

Assign a specific value to a macro knob on a device rack by track, device, and macro index or name.

Instructions

Set a macro knob value on a rack. macro: macro index (0–7) or name (e.g. 'Macro 1', 'Cutoff', etc.) value: within the macro's range (usually 0.0–127.0 or 0.0–1.0)

Behavior2/5

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

No annotations provided, leaving the description to carry the full burden. It does not disclose side effects, permissions, reversibility, or any behavioral traits beyond the basic action. Minimal transparency for a mutation tool.

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

Conciseness5/5

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

Extremely concise: four lines, front-loaded with purpose, then parameter details. Every sentence earns its place with no fluff. Excellent structure.

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

Completeness2/5

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

Despite an output schema existing, the description fails to explain core parameters like track_index and device_index. No prerequisites or context about racks. Incomplete for a tool with four required params.

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

Parameters3/5

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

Schema has 0% description coverage, so the description must compensate. It adds useful meaning for 'macro' (index/name) and 'value' (range), but misses 'track_index' and 'device_index' entirely. Partial compensation, not complete.

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?

Description clearly states 'Set a macro knob value on a rack' with a specific verb and resource. It distinguishes from sibling 'get_macros' but does not explicitly differentiate from similar parameter-setting tools.

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

Usage Guidelines3/5

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

Provides parameter usage for macro and value (index/name examples, value range) but lacks guidance on when to use this tool versus alternatives like 'set_parameter_by_name'. Implied context is present but no exclusions or explicit when/when-not.

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