create_clip

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

With no annotations provided, the description bears the full burden of behavioral disclosure. It fails to state what happens when creating a clip (e.g., overwrite behavior if the slot is occupied, whether the clip is empty, what the return value is, or whether any setup like an armed track is required). The parameter-level details given are helpful but do not reveal the mutation's operational behavior.

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?

One clear lead sentence followed by a minimal parameter list with no fluff or redundancy. Every line earns its place and the structure is immediately scannable.

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 creation tool with an output schema present, the description adequately documents purpose and parameters. However, it omits context on behavioral outcomes—such as whether the default clip is empty or auto-populated, or what happens on conflict—leaving an agent without enough information to predict the effect of the call in edge cases.

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 schema has 0% description coverage, but the description fully compensates by documenting all three parameters with meaningful detail: 1-based indexing for both track_index and clip_index, units in beats for length, and a default value of 4.0. This is essential information the schema alone does not convey.

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 uses a specific verb ('Create') and resource ('MIDI clip') and adds scope with 'in the specified track and clip slot,' which helps distinguish it from siblings like create_arrrangement_midi_clip. However, it never explicitly contrasts itself with these sibling tools, so it just misses top marks.

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?

There is no guidance on when to use this tool versus alternatives such as create_arrangement_midi_clip or add_notes_to_clip. The 1-based parameter hints imply a clip-slot (Session) context, but no explicit when/when-not-to-use, prerequisites, or alternative references are provided.

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