create_clip

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

With no annotations, the description carries full responsibility for behavioral disclosure. It mentions length units but does not explain what happens if the clip_index already contains a clip, whether the operation is reversible, or any required permissions. This leaves uncertainty about potential destructive actions.

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, front-loaded with the action, and contains no unnecessary words. Every word earns its place, and the unit clarification is a high-value addition.

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 creation tool with only three parameters, the description provides the essential purpose and unit clarification. However, it omits behavioral details such as overwrite behavior or success indication. Given no annotations and the presence of an output schema (not shown), the description is adequate but not fully complete.

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?

The description adds significant meaning for the 'length' parameter by clarifying its unit (BEATS). However, 'clip_index' and 'track_index' are not described beyond their names, and the schema provides no descriptions. The tool partially compensates for the 0% schema coverage but leaves two parameters to inference.

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 tool's action ('Create a new empty MIDI clip') with a specific verb and resource. It distinguishes itself from siblings like add_notes_to_clip or delete_clip by specifying it creates an empty clip. The unit clarification ('length is in BEATS (not bars)') adds precision.

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 description implies when to use the tool (when a new empty MIDI clip is needed) but does not explicitly state exclusions or alternatives. It lacks guidance on prerequisites such as existing tracks or clip slots, or when to prefer another tool like duplicate_clip.

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