clip_reverse

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

With no annotations, the description carries the burden of behavioral disclosure. It does disclose the key stateful behavior ('toggles'), implying the operation switches reverse playback on and off and can be undone by calling it again. It does not mention output or wider side effects, but the simple action is reasonably transparent.

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 a single compact sentence with no filler. The core action and the toggling qualifier are both 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?

For a low-complexity tool with only two integer parameters and an output schema, the description provides enough to understand the core function. It is incomplete in not contextualizing the parameters and lacking usage guidance, making it adequate but not strong.

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 needed to clarify track_id and clip_index, but it does not mention either parameter. The parameter names are somewhat self-explanatory in a timeline context, yet the description adds no parameter-level meaning.

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 uses a specific verb (reverse) and resource (timeline clip), and the '(toggles)' qualifier clarifies the exact behavior. It is readily distinguishable from sibling tools like clip_set_speed or timeline_seek, which address different clip/timeline properties.

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 given about when to use this tool versus alternatives, nor any preconditions such as the timeline needing an active clip or the meaning of the indices. The word 'toggles' hints at behavior but not at usage context.

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