set_clip_loop_region

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

With no annotations, the description must disclose behavioral traits but only says 'Set a clip's loop start/end points, in beats.' No mention of side effects, required context (e.g., clip must be in a track), error conditions, or whether start/end are relative to clip or global timeline.

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?

Single sentence, front-loaded with action and subject, no redundant words. Efficiently communicates the core purpose.

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?

Incomplete given 5 parameters and no output schema. Does not specify what the start/end values represent (beat positions from clip start or absolute), whether loop region must be within clip length, or if this works for session or arrangement clips. With sibling tools like 'set_loop_region' and 'set_clip_looping', more context is needed.

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 has 0% description coverage. Description does not explain 'track_index', 'clip_index', or clarify that 'start' and 'end' are in beats relative to the clip's start position. The only added info is 'in beats' but without specifying reference point.

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 'Set', the resource 'clip's loop start/end points', and the unit 'in beats'. It distinguishes from sibling tools like 'set_loop_region' (likely for arrangement loop) and 'set_clip_looping' (toggle loop on/off).

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 versus alternatives. Does not mention prerequisites (e.g., clip must exist, looping must be enabled) or distinguish from 'set_loop_region' or 'set_clip_looping'.

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