create_clip

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

Description does not mention behavior beyond creation: no info on error conditions (e.g., slot occupied), default length, or return value. No annotations provided to compensate.

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?

Description is concise and front-loaded with purpose. Parameter list is clear but could be better structured (e.g., requirements or outputs).

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?

Given lack of annotations and output schema details, description fails to explain important behavior (e.g., overwrite behavior, invalid index handling). Not complete for a creation tool.

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?

Description repeats parameter names and adds brief context (e.g., 'index of the track'), but with 0% schema description coverage, it does not sufficiently compensate. Meaning is largely redundant with schema titles and default.

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?

Description clearly states the action: 'Create a new MIDI clip in the specified track and clip slot.' It uses a specific verb and resource, and distinguishes from sibling tools like create_audio_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?

No guidance on when to use this tool vs alternatives (e.g., add_notes_to_clip, create_audio_clip) or prerequisites (e.g., track must exist, slot must be empty).

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