create_timeline_from_clips

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

With no annotations, the description carries full burden. It discloses the core behavior (creating a timeline from clips) and clarifies the parameter behavior. However, it lacks details on prerequisites (e.g., current folder existence) and edge cases (e.g., no clips available).

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 relatively concise with two paragraphs: a brief overview and an Args block. It avoids unnecessary fluff, though the Args section mimics docstring format which could be streamlined for a tool description.

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 simple two-parameter schema, the description covers the essential aspects. An output schema exists, so return value explanation is not needed. It could mention the timeline is created in the current project, but overall it's sufficient.

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 must compensate. It adds meaning by explaining that 'clip_names' defaults to all clips in the current folder when None. This adds semantic value beyond the schema's basic type and default.

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 tool creates a new timeline from media pool clips, using a specific verb and resource. It distinguishes itself from sibling tools like 'create_empty_timeline' by specifying the source (clips).

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 explains when to use the tool and provides guidance on the optional clip_names parameter, including how omitting it uses all clips. However, it does not explicitly state when not to use it or compare with alternatives like 'append_clips_to_timeline'.

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