# Skill Flows

> Design skills visually on a drag-and-drop canvas

Skill Flows let you design a skill as a diagram instead of a description or code. You place nodes on a canvas, connect them left to right, and click **Build skill**. RelayHub compiles the diagram into a working skill.

Start one with **Skill Flow** in Skills header. Existing flows live in the **Flows** tab.

## Node Types

A flow reads left to right and uses four node types from the palette:

| Node        | Purpose                                                                          |
| ----------- | -------------------------------------------------------------------------------- |
| **Trigger** | How the skill starts: a chat phrase, a file upload, a schedule, or a webhook     |
| **Connect** | An external service call (Salesforce, monday.com, and other connected services)  |
| **Think**   | A pure AI step: summarize, decide, transform, draft                              |
| **Result**  | What the skill produces: a file in a chosen format, or a write back to a service |

A typical flow: **Trigger** (user asks for a pipeline report) connects to **Connect** (pull Salesforce opportunities) connects to **Think** (summarize and rank) connects to **Result** (PDF report).

## Building a Flow

<Steps>
  <Step title="Describe it, or start blank">
    A "Describe my skill" prompt offers to draft the flow from a sentence. Skip it to start with an empty canvas.
  </Step>

  <Step title="Place and configure nodes">
    Click a node type in the left palette to add it. Each node opens an inspector on the right with its settings: trigger phrases for Triggers, service and action for Connects, instructions for Thinks, format and filename for Results. A Think node can also be set to loop with the user until they approve the draft.
  </Step>

  <Step title="Wire the nodes">
    Drag from a node's handle to the next node. Flows run forward only (no loops back); one node can fan out to several.
  </Step>

  <Step title="Validate">
    Click **Validate** to check the structure. Issues appear in the bottom panel with a jump-to-node link for each.
  </Step>

  <Step title="Build">
    Click **Build skill**. Compilation takes about 30 to 60 seconds and produces a real skill, which opens in [Skill Studio](/ai-agents/skill-studio) for review and publishing.
  </Step>
</Steps>

The flow autosaves as you work, so you can leave and return to a draft from the **Flows** tab.

## Advanced Settings

The gear icon opens flow-level settings: the run time limit, the step limit, whether the skill may make outside network calls, and which built-in helpers it can use (for example brand-aware PDF rendering or invoking an automation).

<Note>
  After building, the flow and the compiled skill are linked but separate. Editing the flow and rebuilding produces a new version of the skill; editing the skill directly in Studio does not change the flow.
