photoshop_move_layer_to_top

Idempotent

Move the active layer to the top of the layer stack in Adobe Photoshop, enabling quick layer reordering for compositing or workflow adjustments.

Instructions

Move the active layer to the top of the layer stack

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
document_idYesPhotoshop document id from photoshop_get_state / photoshop_list_documents. Send null or 0 to use the active document. A positive number activates that document before the tool runs. When no document is open, a stale id does not block the call.

TDQS

B3.2/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=false, idempotentHint=true and destructiveHint=false, and the description is consistent with them (repositioning to the top is naturally idempotent and non-destructive). It adds one useful behavioral fact — that the operation targets the currently active layer, implying a layer must be selected first — but says nothing about groups, clipping stacks, or failure modes.

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

Conciseness4/5

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

A single front-loaded sentence with zero filler, stating verb, target, and destination immediately. It is efficiently structured, though the terseness is also the source of its coverage gaps.

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

Completeness3/5

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

For a one-parameter mutation with a fully documented schema and no output schema, the description is minimally sufficient: the agent knows what it does and that it acts on the active layer. It omits any note about layer selection prerequisites, behavior inside groups/clipping masks, or what happens when the layer is already at the top.

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 single document_id parameter is fully documented in the schema, including null/0 semantics and stale-id behavior. The description adds nothing beyond the schema, so the baseline 3 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 ('Move the active layer') plus the destination ('top of the layer stack'), so the action is unambiguous. It does not distinguish itself from close siblings like photoshop_move_layer_to_bottom, photoshop_move_layer_to_position, or photoshop_move_layer_up, which the agent must infer from names alone.

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?

No when-to-use guidance, no prerequisites, and no routing to alternatives such as move_layer_to_position or move_layer_up. The agent gets no help deciding between the several layer-reordering tools in the sibling list.

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