live12_take_lane_create

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 indicates a mutation ('Creates a new take lane') but omits whether existing lanes are affected, whether the new lane is selected, permission requirements, or any side effects beyond the audio/MIDI track context.

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, front-loaded sentence that states the verb and resource immediately. The parenthetical API method adds useful mapping without meaningful bloat.

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 one-parameter mutation, the description states the object and comping context. With no annotations or output schema, however, it should disclose more about side effects or expected result, leaving clear gaps.

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?

There is one required parameter and schema description coverage is 100%, so the schema already documents the zero-based track_index. The description only indirectly references the track and adds no syntax or format detail beyond the schema, so the baseline of 3 applies.

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?

States a specific verb ('Creates') and resource ('new take lane') for comping on an audio or MIDI track, with an API method mapping. The action distinguishes it from take_lane_list and take_lane_comp_region, though it does not explicitly contrast them.

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?

'For comping' gives clear implied context for when this tool applies. However, it does not explicitly say when not to use it or route the agent to alternatives like take_lane_list or take_lane_comp_region.

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