automation_record_channel_volume

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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Record' implies a mutating operation, but the description does not state whether existing automation is overwritten, whether transport must be running, or what side effects occur. This is a significant gap for a write-oriented tool.

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?

The description is two sentences with no wasted words. The core action is front-loaded, and the points format is conveyed efficiently. Every token earns its place.

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 tool with no annotations, no output schema, and loosely specified nested objects, the description leaves critical gaps: the meaning of 'record' in this context, whether existing automation is replaced, the expected units of time_bars and value, and any transport or selection requirements. An agent could guess, but the definition is not complete enough for reliable invocation.

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 compensate. It adds meaning for 'points' by specifying the shape '{time_bars, value}', but it does not explain 'channel' beyond its integer type, nor does it clarify units or ranges for time_bars and value. Partial compensation but incomplete.

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 states a clear verb and resource: 'Record volume automation on a channel.' The phrase 'on a channel' and 'volume' distinguishes it from siblings like automation_record_tempo, automation_record_channel_pan, and automation_record_plugin_param. However, it does not explicitly differentiate from automation_record_mixer_volume, though 'channel' vs 'mixer' provides some implicit distinction.

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 on when to use this tool versus alternatives such as channel_set_volume or automation_record_mixer_volume. There is no mention of prerequisites (e.g., transport state, selection) or exclusions. The agent must infer usage solely from the name and minimal description.

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