live_set_automation

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

With no annotations, the description carries the full behavioral burden. It usefully explains that touch, latch, and write record fader and plug-in moves while the song plays and that the tool returns before/after, but it does not clarify overwrite risks, permissions, transport prerequisites, or what happens to existing automation.

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 short, front-loaded with the core action, and contains no wasted wording. It packs mode enumeration, key behavioral context, and return behavior into a compact statement.

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 two-parameter mutation tool with no annotations and no output schema, the description covers the main purpose, mode semantics, and that a before/after result is returned. It remains incomplete because channel identification is unspecified and important mutation side effects are not addressed.

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 needs to compensate. It gives partial meaning for the mode values by explaining touch, latch, and write behavior, but it leaves read and off unexplained and gives no guidance on how the channel string should be identified.

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 specific verb and resource: setting a mixer channel's automation mode. It enumerates the modes and explicitly points to live_channels for viewing mode values, which helps distinguish this tool from the read-only sibling.

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?

The parenthetical about live_channels implies when to use that sibling for checking modes, but the description does not explicitly say when to use this tool versus alternatives such as live_write_automation. Usage is mostly inferable from the purpose rather than stated as guidance.

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