Create Subsequence

create_subsequence

Split selected clips or a time range into a separate subsequence in Premiere Pro without replacing timeline clips with nested-sequence references.

Instructions

Create a separate subsequence from selected clips or a time range. This Premiere API does not replace the original timeline clips with a nested-sequence reference.

TDQS

A4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, so the safety profile is covered. The description adds meaningful behavioral context beyond annotations by stating that the original timeline clips are not replaced with a nested-sequence reference, which clarifies the mutation's effect on the existing timeline.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences with no wasted wording. The primary purpose is front-loaded, and the second sentence reveals the key behavioral distinction immediately after.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter creation tool with annotations and an output schema, the description is largely complete: it states what is created, from what input, and one important non-replacement behavior. It could be slightly more complete by noting prerequisites such as an active sequence or selected clips, but the missing information is minor.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the only parameter (ignore_track_targeting) is fully documented in the schema. The description does not add any meaning about that parameter, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('Create a separate subsequence') and clarifies the source scope ('from selected clips or a time range'). The second sentence further distinguishes the operation from nested-sequence replacement behavior, helping separate it from siblings such as nest_clips or unnest_sequence.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives implied usage context by naming the possible inputs (selected clips or a time range) and contrasting the result with nested-sequence replacement. However, it does not explicitly state when to use this tool versus create_sequence, duplicate_sequence, nest_clips, or other related siblings, nor does it mention prerequisites such as needing an active sequence.

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