create_clip

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

No annotations are provided, so the description carries the full burden. It states the action but does not disclose what happens if the clip slot already contains a clip, whether the new clip is empty, or any side effects. This leaves important behavioral ambiguity.

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 succinct, front-loads the purpose, and uses a clear parameter list. Every sentence adds value and there is no redundant or filler content.

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 3-parameter tool, the description covers the essential function and parameters. However, it is incomplete regarding behavior on existing clips and the state of the created clip (e.g., empty, length defaults). While not a complex tool, the lack of annotations or output schema leaves notable 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?

The description explicitly explains all three parameters (track_index, clip_index, length) with their meanings and provides a default value for length. The input schema has zero description coverage, so this fully compensates for the schema's lack of parameter documentation.

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 action 'Create a new MIDI clip' and specifies the target as 'the specified track and clip slot'. This distinguishes it from sibling tools like delete_clip, duplicate_clip, and add_notes_to_clip.

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 purpose implies usage but the description does not explicitly state when to use this tool over alternatives, such as when a clip already exists in the slot or when adding notes to an existing clip. No exclusions or alternative recommendations are provided.

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