ae_sequenceLayers

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

The annotations already establish that this is a non-read-only but non-destructive operation in a closed world. The description adds the AE command analogue and the two sequencing modes, but it does not disclose whether layer durations are trimmed, whether existing start times are overwritten, how layer order is determined, or what happens on failure.

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?

A single front-loaded sentence with no filler. The core action, AE analogue, and two mode keywords appear immediately, and every clause contributes useful information.

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?

For a mutation tool with no output schema, the description covers the general operation but omits important operational details: whether the order of the 'layers' array controls sequencing, how 'startTime' is used, and what exactly overlap does to adjacent layer in/out points.

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 60%, with 'layers,' 'stagger,' and 'compositionName' documented. The description adds useful meaning for 'overlap' by clarifying it is in seconds and for 'stagger' by describing it as an offset, but it says nothing about 'startTime' and does not explain the interaction between overlap and layer durations.

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 uses a specific verb and resource: 'arrange layers one after another.' It also names the analogous After Effects command (Keyframe Assistant > Sequence Layers) and distinguishes the two modes (overlap vs. stagger), making it clear how this differs from siblings like ae_alignLayers or ae_reorderLayer.

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?

It clearly explains when the two sequencing modes apply: 'with overlap seconds, or stagger start times by offset.' However, it does not explicitly say when not to use this tool versus alternatives such as ae_alignLayers, ae_reorderLayer, or ae_trimLayer.

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