From f08545548df8167db331bf5ca2d05f106ed5f037 Mon Sep 17 00:00:00 2001 From: Michael Suchacz <203725896+ibetitsmike@users.noreply.github.com> Date: Wed, 3 Dec 2025 13:50:44 +0000 Subject: [PATCH 01/12] =?UTF-8?q?=F0=9F=A4=96=20perf:=20async=20workspace?= =?UTF-8?q?=20name=20generation=20for=20faster=20UX?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Previously, workspace creation blocked for up to 10s while waiting for the AI to generate a workspace name. This caused a poor UX where users had to wait before seeing any result. Changes: - Use generatePlaceholderName() to create workspace immediately with a temporary name derived from the user's message (e.g., 'add-user-auth') - Generate AI name asynchronously in the background - If AI generation succeeds and differs from placeholder, rename workspace - If AI generation or rename fails, gracefully keep the placeholder name The workspace now appears instantly while the AI-generated name is applied as soon as it's available. Users see their workspace right away instead of waiting for the AI provider to respond. _Generated with `mux`_ --- src/node/services/workspaceService.ts | 101 ++++++++++++++---- .../services/workspaceTitleGenerator.test.ts | 37 +++++++ 2 files changed, 118 insertions(+), 20 deletions(-) create mode 100644 src/node/services/workspaceTitleGenerator.test.ts diff --git a/src/node/services/workspaceService.ts b/src/node/services/workspaceService.ts index 3c5633e64..142fe4245 100644 --- a/src/node/services/workspaceService.ts +++ b/src/node/services/workspaceService.ts @@ -14,7 +14,7 @@ import type { InitStateManager } from "@/node/services/initStateManager"; import type { ExtensionMetadataService } from "@/node/services/ExtensionMetadataService"; import { listLocalBranches, detectDefaultTrunkBranch } from "@/node/git"; import { createRuntime, IncompatibleRuntimeError } from "@/node/runtime/runtimeFactory"; -import { generateWorkspaceName } from "./workspaceTitleGenerator"; +import { generateWorkspaceName, generatePlaceholderName } from "./workspaceTitleGenerator"; import { validateWorkspaceName } from "@/common/utils/validation/workspaceValidation"; import type { @@ -416,23 +416,9 @@ export class WorkspaceService extends EventEmitter { | { success: false; error: string } > { try { - const branchNameResult = await generateWorkspaceName(message, options.model, this.aiService); - if (!branchNameResult.success) { - const err = branchNameResult.error; - const errorMessage = - "message" in err - ?
