Implementation Reference
- Handler function that validates input parameters, applies defaults for color and stroke weight, sends the 'set_stroke_color' command to Figma via websocket utility, and returns a formatted text response.async ({ nodeId, r, g, b, a, strokeWeight }) => { try { if (r === undefined || g === undefined || b === undefined) { throw new Error("RGB components (r, g, b) are required and cannot be undefined"); } const colorInput: Color = { r, g, b, a }; const colorWithDefaults = applyColorDefaults(colorInput); const strokeWeightWithDefault = applyDefault(strokeWeight, FIGMA_DEFAULTS.stroke.weight); const result = await sendCommandToFigma("set_stroke_color", { nodeId, color: colorWithDefaults, strokeWeight: strokeWeightWithDefault, }); const typedResult = result as { name: string }; return { content: [ { type: "text", text: `Set stroke color of node "${typedResult.name}" to RGBA(${r}, ${g}, ${b}, ${colorWithDefaults.a}) with weight ${strokeWeightWithDefault}`, }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error setting stroke color: ${error instanceof Error ? error.message : String(error)}`, }, ], }; } }
- Zod input schema defining required node ID and RGB values (0-1), optional alpha and stroke weight.{ nodeId: z.string().describe("The ID of the node to modify"), r: z.number().min(0).max(1).describe("Red component (0-1)"), g: z.number().min(0).max(1).describe("Green component (0-1)"), b: z.number().min(0).max(1).describe("Blue component (0-1)"), a: z.number().min(0).max(1).optional().describe("Alpha component (0-1)"), strokeWeight: z.number().min(0).optional().describe("Stroke weight >= 0)"), },
