set_clip_loop_start

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

With no annotations, the description must fully disclose behavior. It fails to mention side effects, prerequisites (e.g., looping enabled), error conditions, or whether it modifies play state. This is a critical gap for a mutation tool.

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 single sentence is concise but omits essential information. While not verbose, the lack of structure (e.g., separate parameter details) reduces usability. An adequate balance for a minimal description.

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?

Despite an output schema existing (not provided), the description ignores return values and fails to cover necessary context for correct invocation, such as prerequisites or parameter constraints. Incomplete for reliable agent use.

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 coverage is 0%, so the description should explain parameter roles. It only hints at the 'position' unit ('in beats') but does not describe track_index or clip_index, nor their constraints. Minimal added value.

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 specifies the action ('Set') and the target ('clip loop start position') with the unit ('in beats'), distinguishing it from sibling tools like set_clip_loop_end and set_clip_looping.

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 is provided on when to use this tool (e.g., requires loop to be enabled) or alternatives. The agent must infer usage context from siblings without explicit direction.

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