live_arrangement_create_midi_clip

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

No annotations are provided, so the description must carry the full burden. It only states the tool creates an empty clip, but does not disclose side effects (e.g., overwriting existing clips), required state (track selected?), or behavior when called multiple times.

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 with no wasted words, but lacks structure (e.g., bullet points, sections). It is appropriately short for a simple action but could be more organized.

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?

Despite having an output schema (which reduces need for return value explanation), the description fails to contextualize the parameters, confirm behavior, or error conditions. With 5 parameters and 0% schema coverage, the description is underprovided.

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%, and the description does not explain any parameters. For example, 'confirm' and 'name' are left undefined, requiring the agent to infer meaning from names alone.

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 clearly states the verb 'Create', the resource 'empty MIDI clip', and the location 'arrangement timeline of a MIDI track'. This distinguishes it from sibling tools like 'live_create_clip' (which may create in session view) and 'live_arrangement_set_clip_notes' (which modifies existing clips).

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 on when to use this tool versus alternatives. It does not mention prerequisites (e.g., track must exist, selected track), differences from similar tools like 'live_create_clip', or when not to use it.

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