duplicate_clip_loop

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

With no annotations, the description must carry the full burden of behavioral disclosure. It only states the operation doubles the clip length, but does not disclose side effects, error conditions, or changes to the clip's loop settings, leaving significant ambiguity about the mutation 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?

The description is extremely concise, with a clear one-line operation statement followed by a docstring parameter list. Every sentence serves a purpose and there is no unnecessary verbosity.

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?

Given the tool has no annotations and minimal schema descriptions, the description leaves out important context such as prerequisites (e.g., clip must be a loop), exact behavior regarding loop boundaries, and potential side effects. The presence of an output schema mitigates the need for return value details, but the overall context is still thin for an agent to use it safely.

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 description provides zero-based index definitions for both parameters, which adds context beyond the bare schema titles. However, it does not elaborate on how to determine valid indices or any constraints, so the added value is modest.

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 'Duplicate the loop content of a clip' and its effect 'doubling its length', specifying a distinct operation from sibling tools like duplicate_clip. It uses a specific verb and resource, making the tool's purpose unambiguous.

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 versus alternatives. There is no mention of prerequisites, such as the clip being a loop, nor any contrasting with sibling tools like duplicate_clip or set_clip_loop.

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