Fix four root causes in the desktop preview pipeline, surfaced when the model writes the files the user pointed it at: - Output chips guessed paths from prose and could point at a missing file. They are now reconciled against the turn's real changed files: a bare `index.html` resolves to the `todo-app/index.html` actually written, and mentions the turn never changed are dropped. - A standalone single-page index.html got no browser preview (mistaken for a Vite template). It is now only routed to the source view when a package.json/vite.config ships in the same change-set. - Files written outside the session workdir (another folder, or another drive on Windows) failed to preview with 'Path is outside workspace'. The turn's changed-file directories are registered as filesystem access roots; html serves via /local-file and other files via a workdir-relaxed read. - The visual-selection prompt leaked as a raw bubble on Windows because the server-appended '[Image source: ...]' line broke replay dedupe. Replay text is now metadata-normalized before comparison (affects any image message). Adds unit tests for each: htmlPreviewPolicy, assistantOutputTargets reconciliation, replay dedupe + stripGeneratedImageMetadataLines, filesystem access roots, and workspace outside-workdir reads.
Claude Code Haha
A Claude Code build repaired from the source leaked from Anthropic's npm registry on 2026-03-31. Claude Code Haha is now primarily a desktop Claude Code workspace for macOS, Windows, and Linux: sessions, projects, branch / Worktree launch, right-side file changes, code diffs, permission review, provider setup, Computer Use, H5 remote access, IM integration, and scheduled tasks in one app.

Desktop Preview
The Claude Code Haha desktop app brings sessions, multi-project navigation, branch / Worktree controls, right-side file changes, code diffs, permission review, provider setup, and remote access into one graphical workspace for daily development flows beyond the terminal.

Install the Desktop App
- Download the macOS / Windows / Linux desktop installer from Releases.
- On first launch, configure your model provider, API key, and default model in Settings.
- This build is currently unsigned, so the first launch needs a one-time manual approval (clear quarantine on macOS, click "Run anyway" on Windows). See the desktop installation guide.
Run the CLI from Source
For users who want to debug the underlying CLI, server, or local development flow:
bun install
cp .env.example .env
./bin/claude-haha
See environment variables and global usage for more configuration options.
Desktop Highlights
- Multi-session workspace: tabs, project switching, terminal entry, and session history in one place.
- Branch / Worktree launch: choose a repository branch and decide whether to use the current working tree or an isolated Worktree.
- Right-side file changes: review changed files, added/removed lines, and current workspace state while chatting.
- Visual code changes: inspect edits, file writes, and diffs directly in the desktop app.
- Permission review: approve risky commands, tool calls, and model follow-up questions in the GUI.
- Multi-provider setup: configure Anthropic-compatible APIs, third-party models, WebSearch fallback, and local options.
- Computer Use: let the agent take screenshots, click, type, and control desktop apps after authorization.
- H5 remote access: open the current desktop session from a phone or another device with a one-time token.
- IM integration: chat, switch projects, and approve actions through Telegram / Feishu / WeChat / DingTalk.
- Scheduled tasks and usage stats: create planned tasks and track local token usage trends.
