stop_clip

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

No annotations are provided, and the description only states the basic effect. It does not disclose potential side effects, required prior states (e.g., clip must be playing), or error conditions, leaving the agent with insufficient behavioral understanding.

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 short and to the point. However, the parameter descriptions are redundant with the parameter names and could be omitted or integrated more efficiently. It is not verbose but also not optimally concise.

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 simple action tool, the description lacks contextual completeness. It does not mention what happens if the clip is already stopped, if indices are out of range, or any relation to other tools like fire_clip. Despite having an output schema, no return value context is given.

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 coverage is 0%, so the description must compensate. However, the descriptions ('The index of the track containing the clip', 'The index of the clip slot containing the clip') add minimal meaning beyond the parameter names. They are concise but do not clarify indexing conventions or bounds.

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 ('Stop playing a clip') and the resource (a clip). It is specific enough to distinguish from sibling tools like stop_playback (stops all playback) and fire_clip (starts a clip).

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, such as when a clip is already stopped or when to use stop_playback instead. No usage context or prerequisites are mentioned.

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