rapid_trim

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

With no annotations, the description should disclose key behaviors. However, it only states it trims clips to a max duration, without mentioning whether it modifies the original file or creates a copy (though the output_path param hints at the latter). It also does not describe what happens to clips not meeting max_duration or how min_duration interacts.

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 that efficiently conveys the purpose and context. No wasted words, front-loaded with action and resource.

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 6 parameters and no output schema, the description is too minimal. It lacks explanation of how multiple clips are selected (e.g., all or filtered by keywords), the effect of min_duration, the default trim_from behavior, and whether the operation is destructive or creates a new file.

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?

Input schema has 100% coverage with clear descriptions for all 6 parameters. The description adds context about batch operation and fast-paced montages but does not provide additional meaning beyond the schema. Baseline 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 'batch trim clips to a maximum duration for fast-paced montages', specifying the verb (batch trim), resource (clips), and context (fast-paced montages). This differentiates it from sibling tools like trim_clip (likely single clip) and find_long_clips (detection only).

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?

The description implies usage for fast-paced montages but provides no explicit guidance on when to use this tool versus alternatives like trim_clip or find_long_clips. No exclusions or scenarios are mentioned.

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