Play Timeline

play_timeline

Requests playback of the active sequence timeline in Adobe Premiere Pro. Playhead movement isn't verified due to legacy API limitations.

Instructions

Request playback of the active sequence timeline through QE. The legacy API does not provide a same-call playhead readback, so movement is not reported as verified.

TDQS

A3.7/5.0
Behavior4/5

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

Annotations already declare this is a non-read-only, non-idempotent, non-destructive operation. The description adds genuinely useful behavior the annotations cannot convey: that no same-call playhead readback exists, so playback movement is not confirmed. It stops short of saying whether the call blocks or returns immediately, but the verification caveat is valuable.

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?

Two tight sentences with the action first and the caveat second; nothing is redundant and no padding is present.

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?

An output schema exists, so return values need not be described, and there are no parameters to document. The description covers purpose and the key verification limitation, though it could point at the companion tool (e.g. get_playhead_position) for confirming that playback actually advanced.

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

Parameters4/5

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

The tool takes zero parameters, so there are no argument semantics to clarify; the description correctly avoids inventing any. Baseline for a parameterless tool applies.

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

Purpose4/5

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

States a specific verb and resource: 'Request playback of the active sequence timeline', which clearly separates it from stop_playback or get_playhead_position. It does not name a sibling explicitly, but the action is unambiguous.

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

Usage Guidelines2/5

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

There is no statement of when to choose this tool versus alternatives such as stop_playback or navigate_playhead, nor any prerequisite or sequencing guidance. The note about verification is about expectations, not about when or when-not to invoke it.

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