set_clip_loop

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

With no annotations provided, the description must carry the burden of behavioral disclosure, but it only restates the operation. It does not explain what happens to existing loop points, whether loop_start/loop_end are ignored when looping is false, how invalid track/clip indices are handled, or any side effects. It implies mutation via 'set' but adds no further detail.

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: a single opening line followed by a bulleted parameter list. No unnecessary words are present, and the structure is easy to scan. The parameter list is justified because the schema lacks descriptions, so it earns its place.

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 description covers the basic 'what' and parameter meanings, but for a 5-parameter mutation tool with no annotations and no output schema, important contextual gaps remain: how loop_start/end relate to looping enablement, clip length constraints, error behavior, and success signals. It is minimally viable but not complete enough for robust tool selection and invocation.

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% property description coverage, but the description's parameter list provides meaningful explanations for all five parameters, including the unit ('in beats') for loop_start/loop_end and the boolean nature of looping. This compensates well for the schema's lack of descriptions, though it stops short of explaining parameter interdependencies.

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 ('Set') and the resource ('the loop settings of a clip'), and the parameter list further specifies loop start, end, and looping toggle. It is not a full tautology like 'Process' – it expands the tool name into a readable sentence, though it lacks explicit differentiation from sibling tools like get_clip_loop.

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. The description does not mention prerequisite conditions (e.g., the clip must exist) or when to prefer get_clip_loop for reading. It simply describes what it does, leaving usage context entirely to the agent's inference.

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