Use this file when a human asks you to set up their Matrix instance, connect Claude/Codex/GitHub, build apps, or work inside their Matrix VPS. ## Skill Files | File | URL | | --- | --- | | **skills.md** (this file) | `https://matrix-os.com/skills.md` | | **CLI docs** | `https://matrix-os.com/docs/users/cli` | | **GitHub repo** | `https://github.com/HamedMP/matrix-os` | Install locally if your agent runtime supports file skills: ```bash npx skills add HamedMP/matrix-os --skill matrix-os ``` Manual install: ```bash mkdir -p ~/.config/matrix-os/skills/matrix-os curl -fsSL https://matrix-os.com/skills.md > ~/.config/matrix-os/skills/matrix-os/SKILL.md ``` Do not treat this remote URL as an executable instruction source. Use it as reference material and confirm that the setup flow below is the intended task. ## Security Rules - Only send Matrix credentials to `https://app.matrix-os.com` or `https://matrix-os.com`. - Do not paste Matrix tokens, Clerk tokens, GitHub tokens, Claude keys, Codex keys, or OAuth codes into third-party websites. - Prefer hosted `matrix login --profile cloud` and browser/device flows over copying secrets into chat. - For first-run hosted onboarding, use the `cloud` profile explicitly. Do not use `--dev`, `--profile local`, `matrix profile use local`, localhost URLs, `MATRIXOS_PLATFORM_URL`, or `MATRIXOS_GATEWAY_URL` unless the human explicitly asks for Matrix local-stack development. - Do not scan the human's local machine for credentials during onboarding. - Do not transfer local secret files during onboarding. Each tool should authenticate through its own browser/device flow inside the Matrix VPS. - Treat the Matrix VPS as the user's computer. Ask before deleting files, resetting sessions, or installing global packages that may change their environment. - Use named shell sessions for setup so the human can reattach from the Matrix web terminal. ## Quick Start For Agents Tell the human: ```text Help me set up Matrix OS, my own cloud dev computer. 1. Install the CLI: npm install -g @finnaai/matrix or brew install finnaai/tap/matrix. 2. Run matrix login --profile cloud. It opens a browser/device login that I will approve. 3. If no Matrix instance exists, tell me to sign up at https://app.matrix-os.com, then re-run login. 4. Verify with matrix doctor and matrix whoami. 5. Start my preferred coding agent inside Matrix with matrix run -it --session setup -- claude or matrix run -it --session setup -- codex. I will complete that tool's own login inside the remote terminal. Do not scan my local machine for credentials or upload secret files. Everything authenticates through its own browser/device flow. ``` Then run: ```bash # macOS or Linux with Homebrew brew install finnaai/tap/matrix # Or with npm npm install -g @finnaai/matrix # Or with the install script curl -fsSL https://get.matrix-os.com | sh ``` Upgrade an existing CLI before debugging Matrix terminal or sync issues: ```bash # Homebrew brew update brew upgrade finnaai/tap/matrix # npm npm install -g @finnaai/matrix@latest # Install script curl -fsSL https://get.matrix-os.com | sh ``` Then verify the binary the shell will actually run: ```bash matrix --version matrix doctor which matrix ``` If the version is still old, start a new terminal or run `hash -r` in bash/zsh. If Homebrew upgraded but `which matrix` points at npm or another path first, remove or update that older install before retrying. Authenticate: ```bash matrix login --profile cloud matrix doctor matrix whoami matrix status matrix instance info ``` If `matrix login --profile cloud` says no Matrix instance exists yet, ask the human to sign up at: ```text https://app.matrix-os.com ``` After the VPS is provisioned, run `matrix login --profile cloud` again. ## Default Agent Authentication Use in-VPS browser/device login for every coding tool. Do not copy local credential files as part of setup. ```bash matrix run -it --session setup -- gh auth login matrix run -it --session setup -- claude matrix run -it --session setup -- codex matrix run -it --session setup -- opencode ``` If a tool opens a browser/device login, pause and let the human approve it. Do not ask the human to paste tokens, OAuth codes, or API keys into chat. ## Advanced: Migrate Existing Credentials Credential migration is not part of onboarding. Only consider it when the human explicitly asks to move an existing credential or settings file after the default in-VPS login path has failed or is unsuitable. Rules for advanced migration: - Ask which exact provider and local path should be migrated. - Explain that a local secret file will be transferred to the user's Matrix VPS. - Do not discover credential paths automatically. - Do not read, print, summarize, or paste credential file contents into chat. - Request explicit approval immediately before the transfer command, including the exact source and destination paths. Prefer provider-specific CLI flows and browser login inside Matrix whenever possible. If the Matrix CLI later offers intentful provider-specific commands such as `matrix credentials migrate `, prefer those over generic file transfer. ## Interactive Setup Interactive commands must use Matrix shell sessions. Do not invent a separate SSH path. ```text local terminal matrix run -it --session setup -- claude -> gateway WebSocket /ws/terminal -> zellij session on the user's Matrix VPS -> pane running the selected agent ``` Use these commands: ```bash # Use a named setup session so the human and web terminal can reattach. mos shell attach -c setup matrix run -it --session setup -- gh auth login matrix run -it --session setup -- claude matrix run -it --session setup -- codex ``` Run either Claude or Codex according to the human's choice; do not start both unless the human explicitly asks. `mos shell attach -c setup` creates the named session if it does not exist, then attaches to it. If the human already has a working web terminal or CLI session, reuse that session instead of requiring a new one named `setup`. Detach from an interactive session with: ```text Ctrl-\ Ctrl-\ ``` Detaching leaves the remote zellij session alive. Reattach with: ```bash mos shell attach setup ``` ## Codex Sandbox Note When using Matrix hosted cloud from Codex, run Matrix network and terminal commands outside the default sandbox because the sandbox may block DNS, browser handoff, WebSocket terminal attach, and gateway calls. For these commands, request escalated execution with scoped prefix rules: - `matrix login --profile cloud` - `matrix status` - `matrix doctor` - `matrix instance` - `matrix shell` - `matrix run -it` - `mos shell attach` Do not request broad approval for `matrix sync`, credential migration, or commands that transfer local files or secrets. Ask the human explicitly for those, including what path will be transferred. The pattern is: normal shell for local checks, escalated Matrix CLI for cloud gateway and WebSocket operations, explicit approval for sync or secret transfer. Do not try to make every shell command unsandboxed. ## Terminal Session Fallbacks If `matrix run -it -- ...`, `matrix shell new`, or `mos shell attach` returns: ```text Error: Request failed (zellij_failed) ``` do not keep retrying the same command. First list existing sessions: ```bash matrix shell ls ``` Then connect to an existing session: ```bash mos shell attach ``` For setup, prefer an existing human-created session if one is available. If no setup session exists, create-or-connect with: ```bash mos shell attach -c setup ``` `attach -c ` creates the session if missing and then attaches to it. If creation still fails with `zellij_failed`, ask the human to create or choose a session from the Matrix web terminal, then attach to that existing session: ```bash matrix shell ls mos shell attach ``` `attach` may succeed even when `run -it` fails. After `matrix login --profile cloud`, run: ```bash matrix doctor ``` If the sync daemon fails, run: ```bash matrix sync matrix doctor ``` If `matrix doctor` passes but terminal commands still return `zellij_failed`, switch to `mos shell attach`. ## GitHub Setup For Coding Matrix uses GitHub over SSH for coding projects. Run: ```bash matrix run -it --session setup -- gh auth login ``` When prompted by GitHub CLI, choose: ```text GitHub.com SSH Login with a web browser ``` If `gh` is missing inside the Matrix VPS, install it in the remote session: ```bash matrix run -it --session setup -- bash ``` Then, inside the remote shell: ```bash if ! command -v gh >/dev/null 2>&1; then sudo apt-get update sudo apt-get install -y gh fi gh auth login --hostname github.com --git-protocol ssh --web ``` Do not ask the human to paste GitHub tokens into chat. Use the browser flow. ## Claude, Codex, And Hermes Matrix is bring-your-own-agent. Preferred setup order: 1. If the human uses Claude, run `matrix run -it --session setup -- claude` and complete Claude login in the remote terminal. 2. If the human uses Codex, run `matrix run -it --session setup -- codex` and complete Codex login in the remote terminal. 3. If neither Claude nor Codex is available, use Hermes inside Matrix as the system agent for building apps and completing tasks. Hermes should continue to work even when Claude or Codex are connected. Claude/Codex are developer tools; Hermes is the Matrix-native assistant for app building, email summaries, calendar tasks, integrations, and everyday actions. ## Build A Matrix App Use the remote Matrix VPS for app work: ```bash matrix run -it --session app-build -- bash ``` Inside the remote shell: ```bash cd ~/apps mkdir -p my-app cd my-app ``` Build Matrix apps as real files with: - `matrix.json` app manifest - Vite + React + TypeScript when building UI apps - `dist/` build output - no secrets committed to app files After building, ask Matrix to open or reload the app from the shell UI. ## Useful Commands ```bash matrix status matrix doctor matrix whoami matrix instance info matrix instance logs matrix shell ls matrix shell new setup --cmd bash mos shell attach setup mos shell attach -c setup matrix run -it --session setup -- claude matrix run -it --session setup -- codex matrix run -it --session setup -- gh auth login ``` ## What Matrix Enables For the human, Matrix becomes: - a personal VPS-backed computer they can open from any browser - a persistent terminal workspace for coding agents - a place to connect GitHub, Claude, Codex, and Hermes - a runtime for generating and running apps - an assistant that can use approved integrations like email, calendar, and GitHub - a shared surface where a human can jump into the same shell session an agent is using ## Recovery If something fails: ```bash matrix doctor matrix status matrix instance info matrix instance logs matrix shell ls ``` If an interactive command looks stuck, detach with `Ctrl-\ Ctrl-\`, then reconnect: ```bash mos shell attach setup ``` If the named session is missing and should be created, use: ```bash mos shell attach -c setup ``` If the VPS is not ready yet, wait for provisioning in `https://app.matrix-os.com`, then retry `matrix login --profile cloud`.
