create_clip

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

With no annotations, the description should disclose behavioral traits. It does not mention whether creating a clip overwrites an existing clip, what happens if the slot is occupied, or any side effects. The description is vague about the operation's consequences.

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 concise: one sentence followed by a bullet list of parameters. Every sentence adds value, and the most important information is front-loaded.

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?

The tool has no output schema, so the description should clarify return value (likely success indicator) or error conditions. It does not mention what happens after creation, such as whether the clip is selected or if any feedback is given. For a simple command, this omission reduces completeness.

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%, so the description must carry the burden. It explains track_index, clip_index, and length (including unit 'beats' and default value). This adds meaning beyond the schema's titles, though further detail (e.g., valid index ranges) would improve it.

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), the resource (clip in a track and slot), and specifies the location via parameters. It distinguishes from siblings like 'delete_clip' and 'fire_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 description provides no guidance on when to use this tool vs alternatives (e.g., 'add_notes_to_clip', 'capture_midi'), nor does it mention prerequisites like the track and slot must exist and be empty. Missing exclusions for occupied slots.

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