set_focus

Focuses on a specific Figma node by selecting it and scrolling the viewport to it, so you can locate and work on an element using its node ID.

Instructions

Set focus on a specific node in Figma by selecting it and scrolling viewport to it

TDQS

A3.6/5.0
Behavior4/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explicitly mentions both side effects—selecting the node and scrolling the viewport—which is strong transparency for this type of tool. It does not discuss error cases or whether document state changes, but the main observable behavior is disclosed.

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 a single front-loaded sentence with no filler. It states the operation, the target, and the mechanism in an efficient and scannable way.

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 simple, one-parameter tool with no output schema, the description provides sufficient context: what action is performed and what visible effects occur. It does not mention return behavior or failure handling, but for a focus/selection action this is a minor gap rather than a critical omission.

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 nodeId parameter is already described as 'The ID of the node to focus on.' The tool description does not add additional parameter meaning, format details, or constraints, so it stays at the baseline for fully schema-documented parameters.

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?

The description clearly states a specific action—set focus on a node—and adds concrete behavioral detail: selecting the node and scrolling the viewport to it. This distinguishes it from related selection tools, though it does not explicitly reference any sibling tool by name.

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 guidance about when to use this tool instead of alternatives such as set_selections or move_node. The description implies a use case, but it does not state prerequisites, exclusions, or conditions that would route an agent to a different tool.

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