create_timeline_from_clips

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

With no annotations, the description must disclose behavioral traits. It only states 'pre-filled' but omits details like error handling on missing clips, overwrite behavior, permissions needed, or side effects. The create operation likely has destructive potential but is not clarified.

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?

Single sentence, no wasted words. Could benefit from additional context but remains concise and front-loaded. Slightly too brief given complexity.

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 two required params, no output schema, and no annotations, the description is usable but lacks completeness. It does not explain return values, error conditions, or prerequisites. For a timeline creation tool, more detail would improve agent selection.

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 0% (no parameter descriptions). The tool description adds minimal meaning: 'name' is timeline name and 'clip_names' are names of clips. However, it does not specify format, case sensitivity, or uniqueness requirements. Some value added but incomplete.

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 (create), the resource (timeline), and the unique aspect (pre-filled with named media pool clips). This distinguishes it from siblings like create_timeline (empty) and append_clips (adds to existing).

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 on when to use this tool versus alternatives, such as when to create an empty timeline first or how to handle missing clips. No prerequisites or exclusions mentioned.

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