live12_cc_control

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

No annotations are provided, so the description carries the full behavioral burden. It says the tool sets and configures values but does not disclose mutation effects, prerequisites such as the device existing on the specified track, reversibility, or error behavior; only the schema's action enum hints at read vs write operations.

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 a single sentence, front-loaded with the verb and device name, with no filler or repetition. Every phrase contributes to identifying the controlled device and its main capabilities.

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?

The description is minimally adequate given the rich schema, but for a mutating device-control tool with no annotations and no output schema, it omits prerequisites, side effects, and expected result behavior. It tells the agent what device is controlled but not enough about safe invocation conditions.

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 100%, with detailed descriptions for every parameter including the action enum and CC examples. The description adds no parameter-level syntax or constraints beyond what the schema already provides, so the baseline score of 3 is appropriate.

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 ('Controls') and resource ('Ableton Live 12 CC Control MIDI device'), then enumerates three capabilities: mapping CC, setting output CC values, and configuring automation targets. It does not explicitly distinguish itself from adjacent device/parameter tools such as live12_device_set_parameter, so it is clear but not fully sibling-differentiated.

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?

Usage is implied by the named device and the action enum in the schema, but the description gives no explicit when-to-use or when-not-to-use guidance. It also does not mention alternatives such as live12_device_set_parameter or clip envelope tools, leaving routing decisions to the agent.

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