trim_clip

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

While annotations indicate the tool modifies (readOnlyHint=false), the description does not disclose potential side effects such as affecting other clips, whether trimming is non-destructive, or if the trimmed media is discarded. No additional behavioral context is added beyond the annotations.

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 sentence, effectively communicating the core action without unnecessary words. However, it could be slightly more structured, but it remains efficient and 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?

No output schema exists, and the description does not mention return values or success indicators. For a mutation tool, this is a gap. Additionally, preconditions (e.g., clip must exist on timeline) are not stated, leaving the agent with incomplete information.

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 100%, with each parameter having a clear description. The tool description adds no extra meaning beyond what the schema already provides, so baseline score of 3 is appropriate.

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 verb 'Trim' and the resource 'clip's in or out point', making the tool's purpose immediately understandable. It distinguishes from sibling tools like 'split_clip' or 'move_clip' by focusing on adjusting in/out points.

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 like 'split_clip', 'ripple_delete', or 'set_clip_start_time'. The description lacks any exclusions or context about prerequisites or typical use cases.

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