CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview — CRITICAL MENTAL MODEL

This repo IS the USB drive content, minus large dependencies. The relationship:

代码库（git）= U 盘骨架（脚本 + HTML + 小文件）
     ↓ bash setup.sh
完整文件夹 = U 盘内容（骨架 + Node.js + OpenClaw）
     ↓ 拷贝到 U 盘
U 盘 = 插上就能用

The repo is NOT a "build tool" or "generator" — it IS the USB structure. setup.sh only fills in large deps that can't go in git. After setup.sh, the portable/ folder is directly copyable to a USB drive.

Distribution forms:

1. Portable USB (portable/): Run from USB on existing Mac/Windows, zero install. This is the only form CI publishes (Windows full zip; Mac runs setup.sh on first launch).
2. Bootable Linux USB (bootable/): Ventoy + Ubuntu 24.04 — boots any x86_64 PC from USB, no OS needed. Independent module, user-run scripts (not in CI).
3. One-line install (install/): curl | bash or irm | iex — download and install from network, no USB needed. User-run scripts (not in CI).

Deprecated (2026-06-19): Electron desktop app (u-claw-app/, DMG/EXE) is no longer built or published — it was a weaker duplicate of the commercial ClawX desktop and had cold-start gateway-timeout bugs. Code is kept for archive only; see u-claw-app/DEPRECATED.md. The desktop-windows/desktop-mac CI jobs were removed from release.yml.

Removed: usb-release/ — an abandoned older predecessor of portable/ (last touched 2026-04, core/+skills/ layout, referenced nowhere). Deleted 2026-06-19.

Tests

node --test tests/              # Run all tests (node:test, no test framework dep)
node --test tests/windows-launchers.test.mjs   # Run one test file

Tests assert on the text/behavior of the launchers and shared .mjs helpers — e.g. that the Start launchers stay thin shells over lib/start.mjs, that .bat files are pure ASCII with CRLF, that no China-routed download source comes back, that the two installers resolve skills the same way, and that every message key exists in every catalogue. They read repo files as strings; they do not spawn OpenClaw. There is no root package.json. As of 2026-08-17 tests do run in CI — .github/workflows/tests.yml runs node --test tests/ on every push and PR. Before that they were local-only, so the guards they encode could regress unnoticed.

CI workflows (.github/workflows/): release.yml builds Win/Mac portable + desktop and publishes a GitHub Release on tag push. track-upstream.yml runs daily (cron) — checks npm view openclaw version against the pinned OPENCLAW_VERSION; if upstream is newer it bumps both OPENCLAW_VERSION files + the desktop shell version (u-claw-app/package.json patch), commits, and pushes a new v<shell-version> tag, which in turn triggers release.yml. Supports workflow_dispatch with force_version / dry_run inputs. OPENCLAW_VERSION is the upstream pin; u-claw-app/package.json is the shell version (the two are separate).

Testing of the actual runtime should be done in a separate folder or directly on USB. This repo stays clean (no node_modules, no app/ runtime).

Architecture

portable/           THE USB content (= repo + setup.sh downloads)
                    setup.sh / setup.bat / setup.ps1 — fill in app/ (Node + OpenClaw + plugins)
                    {Mac,Windows}-Start    — launch gateway + config-server, open dashboard/Config
                    {Mac,Windows}-Menu     — interactive CLI launcher (pick start/config/CLI/diagnose)
                    {Mac,Windows}-Install  — copy USB → computer (~/.uclaw/ or %USERPROFILE%)
                    {Mac,Windows}-Diagnose — health check / collect logs for bug reports
                    {Mac-OpenClaw-CLI,OpenClaw-CLI.bat} — drop into raw `openclaw` CLI
                    *.html (Welcome, U-Claw, SkillHub) — local UI pages
                    Config.html — redirect shim only; the settings UI itself is
                        config-server/public/index.html (single implementation since 2026-08-17).
                        The old standalone copy called the API on a root-relative path, which
                        cannot work from file:// — Save failed silently for anyone who opened it.
                    config-server/server.js — local HTTP server (port 18788-18798) backing
                        Config.html: writes openclaw.json, WeChat QR login, update-status API
                    lib/                   — Node helpers (see "lib/ helpers" below)
                    default-config.json    — seed config copied to data/.openclaw/ on first run
                    app/core/ (OpenClaw) + app/runtime/ (Node.js) — downloaded by setup.sh
                    data/.openclaw/openclaw.json — user config (on USB, portable)
skills/             Single source of truth for skill content + distribution (2026-08-17).
                    manifest.json — the only thing installers read
                    en/<id>/SKILL.md — content
                    Replaces the old three-way split (portable/skills-cn/ on disk,
                    heredocs in install.sh, here-strings in install.ps1). See skills/README.md.
                    Installed by lib/install-skills.mjs; release.yml copies skills/ + the
                    installer onto the drive so it can re-install offline.

u-claw-app/         [DEPRECATED 2026-06-19, archived — not built/published] Electron desktop app
                    (main.js ~400 lines). Kept for archive only; see u-claw-app/DEPRECATED.md.
                    Bundles Node.js in resources/runtime/node-{platform}-{arch}

bootable/           Linux 可启动 U 盘模块（完全独立，不依赖其他模块）
                    4 步 PowerShell 脚本 (Windows 上制作)
                    Ventoy 1.0.99 + Ubuntu 24.04 LTS + casper-rw 持久化
                    linux-setup/ — setup-openclaw.sh 安装到 /opt/u-claw/
                    独立仓库镜像: gitea.fanghe.it.com/zhenghy/u-claw-linux

install/            一键在线安装模块（curl | bash / irm | iex）
                    install.sh (Mac/Linux) + install.ps1 (Windows)
                    7 步流程: 系统检测 → Node.js → OpenClaw → QQ插件 → 技能(读 skills/manifest.json) → 模型配置 → 启动脚本
                    安装到 ~/.uclaw/，与 Mac-Install.command 结果相同

This is a fork. Upstream is github.com/dongsheng123132/u-claw; we host at gitea.fanghe.it.com/zhenghy/u-claw and do not send changes back — the overseas build removes the China-market defaults that are the point of the upstream project. See origin.json for every URL this build fetches at runtime, and the migration notes in the workspace root.

The website is upstream's and we do not have it. They split it out on 2026-04-14 (commit 65f830e) into a private repo of their own. guide.html lives there, so the website work in the overseas plan is blocked until we either get access or build our own.

Both portable and desktop versions auto-find a free port in range 18789–18799 and start the OpenClaw gateway. On first run, they detect whether a model is configured — if not, they open Config.html; otherwise, they open the dashboard.

Key Technical Details

• Node.js discovery: Portable looks at app/runtime/node-mac-arm64/bin/node; Electron looks at resources/runtime/node-{platform}-{arch} then falls back to system node
• Download sources (overseas build, 2026-08-17): Node.js binaries from nodejs.org/dist, npm packages from registry.npmjs.org, GitHub assets direct. No China-routed mirrors or GitHub proxies remain in scripts, launchers or CI — tests/no-china-sources.test.mjs fails the build if any come back.
• OPENCLAW_VERSION file: single source of truth for the bundled OpenClaw runtime version (e.g. 2026.6.8). CI reads it to pin the npm install; it's copied into portable/ so USB users / check-update.mjs can compare installed vs latest. Bump this file to upgrade.
• Environment variables: OPENCLAW_HOME, OPENCLAW_STATE_DIR, OPENCLAW_CONFIG_PATH control where OpenClaw reads config
• macOS quarantine: Mac scripts run xattr -rd com.apple.quarantine to remove Gatekeeper blocks
• Config format: {"gateway":{"mode":"local","auth":{"token":"uclaw"}},"models":{"mode":"merge","providers":{"xxx":{...}}},"agents":{"defaults":{"model":{"primary":"provider/model"}}}}
• Config hot-reload: OpenClaw watches openclaw.json and applies changes without restart
• Two local servers on startup: launchers start the OpenClaw gateway (18789–18799) AND the config-server (config-server/server.js, 18788–18798). The config-server backs Config.html — it writes openclaw.json, drives WeChat QR login, and exposes update-status.

lib/ Helpers (portable)

Pure-Node, zero-dependency .mjs modules (use fetch + node:zlib only). All are designed to fail silently and run detached so they never block or break OpenClaw startup.

File	Purpose
check-update.mjs / publish-latest.mjs	Portable self-update: check installed vs latest OPENCLAW_VERSION; publish helper.
portable-cache.mjs	启动加速核心：把"重 IO、可重建"的缓存从 U 盘搬到本机硬盘。算出本机缓存根（win %LOCALAPPDATA%\U-Claw\<slot> / mac ~/Library/Caches/U-Claw / linux $XDG_CACHE_HOME，UUID 隔离让换盘符仍复用），输出 NODE_COMPILE_CACHE 路径，并把 data/.openclaw/browser 做成 junction(win)/symlink(mac) 指向本机盘——浏览器 user-data 的海量随机小写不再砸 U 盘。CLI 打印 KEY=VALUE 供启动脚本 source。静默失败：取不到就缓存留 U 盘照常启动。
prewarm.mjs	gateway 首轮预热：端口就绪后后台静默 GET /ready→/status→/models（带 x-openclaw-token），把 config/model 子系统在 runtime 内存里热起来，用户首次点发送不再等。零依赖、短超时、后台 detach。
loading.html	启动首屏（splash）：双击启动后立刻打开，给即时反馈消除"黑窗假死"。本页每秒 fetch /ready，gateway 真就绪后自动 location.replace 跳 Dashboard——天然规避"gateway 没起就开 Dashboard 拒连"(issue #46/#48)。端口经 ?port= 传入。
start.mjs	启动主逻辑（2026-08-17 起）：运行时检测、数据目录、缓存加速、默认配置、依赖安装、NO_PROXY、微信插件、config-server 启动与端口发现、gateway 端口扫描、首屏与控制台打开、预热、兜底轮询、退出清理。.bat/.command 退化为 ~30 行的启动壳。这样两平台不会再漂，且所有面向用户的文案可翻译。
i18n.mjs + messages/{en,zh-CN}.json	启动器与本地页面的词条。语言优先级：显式覆盖 > 盘内配置 uclaw.locale > 系统 locale > en —— 语言跟盘走，不跟机器走。key 用语义命名，缺失自动回落英文。
wait-gateway.bat	已移除（2026-08-17）。兜底轮询并入 start.mjs 的 watchGatewayReady()，现在 macOS 也有了 —— 此前只有 Windows 有。
maintain.sh	Maintenance/diagnostics script.

启动加速（吸收自 v2 u-clawx 4.0 的工程经验，2026-06-17）

便携版从 U 盘启动慢，瓶颈在 U 盘随机小写 IO + 首屏无反馈 + 首轮冷启动。移植 4.0 的 4 个可在纯脚本层复刻的手段：

1. 缓存搬本机（portable-cache.mjs）：浏览器 user-data（OpenClaw 硬编码在 CONFIG_DIR/browser/，无单独环境变量，故用 junction/symlink 重定向）+ V8 编译缓存（NODE_COMPILE_CACHE）落本机 SSD。业务数据（openclaw.json、memory、账号）仍留 U 盘，便携性不变。UUID 隔离让 D:→E: 换盘符仍命中同一份本机缓存。
2. Node 编译缓存：openclaw.mjs 本就调 module.enableCompileCache()，但默认落系统 temp（可能被清）。启动脚本显式把 NODE_COMPILE_CACHE 指向本机固定目录，二次启动稳定命中。
3. 启动首屏（loading.html）：双击即弹，自轮询自跳转。
4. 首轮预热（prewarm.mjs）：后台唤醒 config/model。
5. 动态探测：Windows 把写死的 timeout /t 2（等 config-server）改成轮询 18788，省掉白等。

注：OpenClaw 自身的临时/lock/chrome-mcp 文件已走 os.tmpdir()（系统 temp，不在 U 盘），无需处理；真正落 U 盘的只有 OPENCLAW_HOME=data/ 下的内容。

纯开源,无追踪: 这个开源版不含设备指纹 (fingerprint.mjs)、自动开户 (bootstrap-xiapan.mjs/xiapan-client.mjs)、崩溃上报 (report-bug.mjs) 等商业版逻辑——这些已在 2026-06-17 移除。U-Claw 不绑定设备、不打指纹、不向 api.u-claw.org 上传任何数据。

模型配置 ("选模型填 Key")

设置页（config-server/public/index.html，旧入口 Config.html 会重定向过来）列出模型供用户挑选。首选卡片是 虾盘云 (Xiapan Cloud 中转站,api.u-claw.org/v1) ——一个 Key 调用 DeepSeek / Claude / GPT / 通义 等全部模型,但和其它 provider 一样需要用户自己去 https://u-claw.org/cloud.html 注册拿 Key,不再自动开户。其余 provider (DeepSeek/通义/Kimi/智谱/ 豆包/MiniMax/OpenAI/Claude/Groq/硅基流动/自定义) 填各家官方 Key 即可。配置只写本地 data/.openclaw/openclaw.json。

What NOT to Commit

Never commit runtime dependencies or build artifacts. These are all in .gitignore:

• portable/app/ and portable/data/ (runtime + user data)
• u-claw-app/node_modules/, u-claw-app/release/, u-claw-app/resources/runtime/
• *.dmg, *.exe, *.blockmap

Release artifacts go to GitHub Releases, not the repo.

Branding Rules

• Use only official openclaw (not openclaw-cn or any community fork)
• All npm installs reference openclaw@latest (official package)
• External links point to u-claw.org (our site) or github.com/openclaw/openclaw (upstream)
• No references to competitor products (Qclaw, AutoClaw) in any tracked files
• Skill marketplace links point to skillhub.tencent.com or github.com/openclaw/clawhub
