# 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. ## Development Commands ```bash # Portable version — build dev copy cd portable/advanced && bash setup.sh # Downloads Node.js v22 + OpenClaw + plugins into ../app/ cd .. && bash "START HERE - Mac.command" # Launch (Mac). Windows: double-click "START HERE - Windows.bat" # Copy to USB drive cp -R portable/ /Volumes/YOUR_USB/U-Claw/ # Electron desktop app cd u-claw-app && bash setup.sh # One-click: Node.js + Electron + deps npm run dev # Dev mode npm run build:mac-arm64 # Build Mac ARM64 DMG npm run build:win # Build Windows NSIS + portable # Bootable Linux USB (run on Windows PowerShell as Admin) cd bootable .\1-prepare-usb.ps1 # Write Ventoy to USB (formats drive!) .\2-download-iso.ps1 # Download Ubuntu ISO (~5.8GB) .\3-create-persistence.ps1 # Create 20GB ext4 persistence image .\4-copy-to-usb.ps1 # Copy ISO + persistence + scripts to USB ``` ### Tests ```bash node --test # Run every test (node:test, no framework dependency) node --test tests/windows-launchers.test.mjs # Run one file # NOT `node --test tests/` — Node reads that path as a module to load and dies # with "Cannot find module". That form was documented here for years, which is # a good part of why the suite went unrun. ``` 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`. **Enable the pre-push hook after cloning** — it is per-clone and nothing installs it for you: ```bash git config core.hooksPath .githooks ``` It runs the suite and the generated-file check before anything leaves your machine. `git push --no-verify` skips it. This matters because CI cannot be relied on here: the suite went unrun for the whole life of the upstream project, and on our own Gitea the workflow produced zero runs — most likely no runner is registered. The hook is the one layer that works with no server support at all. **As of 2026-08-17 tests also run in CI where a runner exists** — `.github/workflows/tests.yml` runs `node --test` 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` 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//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).

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\` / 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` ## Platform Support Status - Mac Apple Silicon (ARM64): ✅ Working - Mac Intel (x64): ✅ Working（portable 需先运行 setup.sh 下载 node-mac-x64） - Windows x64: 🚧 In development - Linux x64 (Bootable USB): ✅ `bootable/` 目录 + 独立仓库 [u-claw-linux](https://gitea.fanghe.it.com/zhenghy/u-claw-linux) ## Bootable Linux Key Details - **制作环境**: Windows 10/11 + PowerShell (Admin)，4 步脚本 - **U 盘要求**: 32GB+ USB 3.0 - **技术栈**: Ventoy 1.0.99 引导 → Ubuntu 24.04 ISO → casper-rw 持久化 → OpenClaw 安装到 /opt/u-claw/ - **下载源**: ISO 走 releases.ubuntu.com，Node.js 走 nodejs.org，npm 走 registry.npmjs.org - **Linux 环境变量**: `OPENCLAW_HOME=/opt/u-claw/data/.openclaw` - **bootable/ 完全独立**: 不引用 portable/、u-claw-app/ 的任何文件，修改互不影响 - **同步**: bootable/ 内容与 u-claw-linux 仓库保持一致，改一边要记得同步另一边
