fix: persist full container state across stop/start and config-change recreation

- Add home volume (triple-c-home-{id}) for /home/claude to persist
  .claude.json, .local, and other user-level state across restarts
- Add docker commit before recreation: when container_needs_recreation()
  triggers, snapshot the container to preserve system-level changes
  (apt/pip/npm installs), then create the new container from that snapshot
- On Reset/removal: delete snapshot image + both volumes for clean slate
- Remove commit from stop_project_container (stop/start preserves the
  writable layer naturally; no commit needed)

+
+For a universal binary (recommended for distribution):
+
+```bash
+npx tauri build --target universal-apple-darwin

+## Project Overview
+
+Triple-C (Claude-Code-Container) is a Tauri v2 desktop application that sandboxes Claude Code inside Docker containers. It has two main parts: a React/TypeScript frontend, a Rust backend, and a Docker container image definition.
+
+## Build & Development Commands
+
+All frontend/tauri commands run from the `app/` directory:
+
+```bash
+cd app
+npm ci                    # Install dependencies (required first time)
+npx tauri dev             # Launch app in dev mode with hot reload (Vite on port 1420)
+npx tauri build           # Production build (outputs to src-tauri/target/release/bundle/)
+npm run build             # Frontend-only build (tsc + vite)
+npm run test              # Run Vitest once
+npm run test:watch        # Run Vitest in watch mode
+```
+
+Rust backend is compiled automatically by `tauri dev`/`tauri build`. To check Rust independently:
+```bash
+cd app/src-tauri
+cargo check               # Type-check without full build
+cargo build               # Build Rust backend only
+```
+
+Container image:
+```bash
+docker build -t triple-c-sandbox ./container
+```
+
+### Linux Build Dependencies (Ubuntu/Debian)
+```bash
+sudo apt-get install -y libgtk-3-dev libwebkit2gtk-4.1-dev libayatana-appindicator3-dev librsvg2-dev libsoup-3.0-dev patchelf libssl-dev pkg-config build-essential
+```
+
+## Architecture
+
+### Two-Process Model (Tauri IPC)
+
+- **React frontend** (`app/src/`) renders UI in the OS webview
+- **Rust backend** (`app/src-tauri/src/`) handles Docker API, credential storage, and terminal I/O
+- Communication uses two patterns:
+  - `invoke()` — request/response for discrete operations (CRUD, start/stop containers)
+  - `emit()`/`listen()` — event streaming for continuous data (terminal I/O)
+
+### Terminal I/O Flow
+
+```
+User keystroke → xterm.js onData() → invoke("terminal_input") → mpsc channel → docker exec stdin
+docker exec stdout → tokio task → emit("terminal-output-{sessionId}") → listen() → xterm.js write()
+```
+
+### Frontend Structure (`app/src/`)
+
+- **`store/appState.ts`** — Single Zustand store for all app state (projects, sessions, UI)
+- **`hooks/`** — All Tauri IPC calls are encapsulated in hooks (`useTerminal`, `useProjects`, `useDocker`, `useSettings`)
+- **`lib/tauri-commands.ts`** — Typed `invoke()` wrappers; TypeScript types in `lib/types.ts` must match Rust models
+- **`components/terminal/TerminalView.tsx`** — xterm.js integration with WebGL rendering, URL detection for OAuth flow
+- **`components/layout/`** — TopBar (tabs + status), Sidebar (project list), StatusBar
+- **`components/projects/`** — ProjectCard, ProjectList, AddProjectDialog
+- **`components/settings/`** — Settings panels for API keys, Docker, AWS
+
+### Backend Structure (`app/src-tauri/src/`)
+
+- **`commands/`** — Tauri command handlers (docker, project, settings, terminal). These are the IPC entry points called by `invoke()`.
+- **`docker/`** — Docker API layer using bollard:
+  - `client.rs` — Singleton Docker connection via `OnceLock`
+  - `container.rs` — Container lifecycle (create, start, stop, remove, inspect)
+  - `exec.rs` — PTY exec sessions with bidirectional stdin/stdout streaming
+  - `image.rs` — Image build/pull with progress streaming
+- **`models/`** — Serde structs (`Project`, `AuthMode`, `BedrockConfig`, `ContainerInfo`, `AppSettings`). These define the IPC contract with the frontend.
+- **`storage/`** — Persistence: `projects_store.rs` (JSON file with atomic writes), `secure.rs` (OS keychain via `keyring` crate), `settings_store.rs`
+
+### Container (`container/`)
+
+- **`Dockerfile`** — Ubuntu 24.04 base with Claude Code, Node.js 22, Python 3.12, Rust, Docker CLI, git, gh, AWS CLI v2, ripgrep, pnpm, uv, ruff pre-installed
+- **`entrypoint.sh`** — UID/GID remapping to match host user, SSH key setup, git config, docker socket permissions, then `sleep infinity`
+- **`triple-c-scheduler`** — Bash-based scheduled task system for recurring Claude Code invocations
+
+### Container Lifecycle
+
+Containers use a **stop/start** model (not create/destroy). Installed packages persist across stops. The `.claude` config dir uses a named Docker volume (`triple-c-claude-config-{projectId}`) so OAuth tokens survive even container resets.
+
+### Authentication
+
+Per-project, independently configured:
+- **Anthropic (OAuth)** — `claude login` in terminal, token persists in config volume
+- **AWS Bedrock** — Static keys, profile, or bearer token injected as env vars
+
+## Styling
+
+- **Tailwind CSS v4** with the Vite plugin (`@tailwindcss/vite`). No separate tailwind config file.
+- All colors use CSS custom properties in `index.css` `:root` (e.g., `--bg-primary`, `--text-secondary`, `--accent`)
+- `color-scheme: dark` is set on `:root` for native dark-mode controls
+- **Do not** add a global `* { padding: 0 }` reset — Tailwind v4 uses CSS `@layer`, and unlayered CSS overrides all layered utilities
+
+## Key Conventions
+
+- Frontend types in `lib/types.ts` must stay in sync with Rust structs in `models/`
+- Tauri commands are registered in `lib.rs` via `.invoke_handler(tauri::generate_handler![...])`
+- Tauri v2 permissions are declared in `capabilities/default.json` — new IPC commands need permission grants there
+- The `projects.json` file uses atomic writes (write to `.tmp`, then `rename()`). Corrupted files are backed up to `.bak`.
+- Cross-platform paths: Docker socket is `/var/run/docker.sock` on Linux/macOS, `//./pipe/docker_engine` on Windows
+
+## Testing
+
+Frontend tests use Vitest with jsdom environment and React Testing Library. Setup file at `src/test/setup.ts`. Run a single test file:
+```bash
+cd app
+npx vitest run src/path/to/test.test.ts
+```

+# How to Use Triple-C
+
+Triple-C (Claude-Code-Container) is a desktop application that runs Claude Code inside isolated Docker containers. Each project gets its own sandboxed environment with bind-mounted directories, so Claude only has access to the files you explicitly provide.
+
+---
+
+## Prerequisites
+
+### Docker
+
+Triple-C requires a running Docker daemon. Install one of the following:
+
+| Platform | Option | Link |
+|----------|--------|------|
+| **Windows** | Docker Desktop | https://docs.docker.com/desktop/install/windows-install/ |
+| **macOS** | Docker Desktop | https://docs.docker.com/desktop/install/mac-install/ |
+| **Linux** | Docker Engine | https://docs.docker.com/engine/install/ |
+| **Linux** | Docker Desktop (alternative) | https://docs.docker.com/desktop/install/linux/ |
+
+After installation, verify Docker is running:
+
+```bash
+docker info
+```
+
+> **Windows note:** Docker Desktop must be running before launching Triple-C. The app communicates with Docker through the named pipe at `//./pipe/docker_engine`.
+
+> **Linux note:** Your user must have permission to access the Docker socket (`/var/run/docker.sock`). Either add your user to the `docker` group (`sudo usermod -aG docker $USER`, then log out and back in) or run Docker in rootless mode.
+
+### Claude Code Account
+
+You need access to Claude Code through one of:
+
+- **Anthropic account** — Sign up at https://claude.ai and use `claude login` (OAuth) inside the terminal
+- **AWS Bedrock** — An AWS account with Bedrock access and Claude models enabled
+
+---
+
+## First Launch
+
+### 1. Get the Container Image
+
+When you first open Triple-C, go to the **Settings** tab in the sidebar. Under **Docker**, you'll see:
+
+- **Docker Status** — Should show "Connected" (green). If it shows "Not Available", make sure Docker is running.
+- **Image Status** — Will show "Not Found" on first launch.
+
+Choose an **Image Source**:
+
+| Source | Description | When to Use |
+|--------|-------------|-------------|
+| **Registry** | Pulls the pre-built image from `repo.anhonesthost.net` | Fastest setup — recommended for most users |
+| **Local Build** | Builds the image locally from the embedded Dockerfile | If you can't reach the registry, or want a custom build |
+| **Custom** | Use any Docker image you specify | Advanced — bring your own sandbox image |
+
+Click **Pull Image** (for Registry/Custom) or **Build Image** (for Local Build). A progress log will stream below the button. When complete, the status changes to "Ready" (green).
+
+### 2. Create Your First Project
+
+Switch to the **Projects** tab in the sidebar and click the **+** button.
+
+1. **Project Name** — Give it a meaningful name (e.g., "my-web-app").
+2. **Folders** — Click **Browse** to select a directory on your host machine. This directory will be mounted into the container at `/workspace/<folder-name>`. You can add multiple folders with the **+** button at the bottom of the folder list.
+3. Click **Add Project**.
+
+### 3. Start the Container
+
+Select your project in the sidebar and click **Start**. The status dot changes from gray (stopped) to orange (starting) to green (running).
+
+### 4. Open a Terminal
+
+Click the **Terminal** button (highlighted in accent color) to open an interactive terminal session. A new tab appears in the top bar and an xterm.js terminal loads in the main area.
+
+Claude Code launches automatically with `--dangerously-skip-permissions` inside the sandboxed container.
+
+### 5. Authenticate
+
+**Anthropic (OAuth) — default:**
+
+1. Type `claude login` or `/login` in the terminal.
+2. Claude prints an OAuth URL. Triple-C detects long URLs and shows a clickable toast at the top of the terminal — click **Open** to open it in your browser.
+3. Complete the login in your browser. The token is saved and persists across container stops and resets.
+
+**AWS Bedrock:**
+
+1. Stop the container first (settings can only be changed while stopped).
+2. In the project card, switch the auth mode to **Bedrock**.
+3. Expand the **Config** panel and fill in your AWS credentials (see [AWS Bedrock Configuration](#aws-bedrock-configuration) below).
+4. Start the container again.
+

+```
+
+- **TopBar** — Terminal tabs for switching between sessions. Status dots on the right show Docker connection (green = connected) and image availability (green = ready).
+- **Sidebar** — Toggle between the **Projects** list and **Settings** panel.
+- **Terminal View** — Interactive terminal powered by xterm.js with WebGL rendering.
+- **StatusBar** — Counts of total projects, running containers, and open terminal sessions.
+
+---
+
+## Project Management
+
+### Project Status
+
+Each project shows a colored status dot:
+
+| Color | Status | Meaning |
+|-------|--------|---------|
+| Gray | Stopped | Container is not running |
+| Orange | Starting / Stopping | Container is transitioning |
+| Green | Running | Container is active, ready for terminals |
+| Red | Error | Something went wrong (check error message) |
+
+### Project Actions
+
+Select a project in the sidebar to see its action buttons:
+
+| Button | When Available | What It Does |
+|--------|---------------|--------------|
+| **Start** | Stopped | Creates (if needed) and starts the container |
+| **Stop** | Running | Stops the container but preserves its state |
+| **Terminal** | Running | Opens a new terminal session in this container |
+| **Reset** | Stopped | Destroys and recreates the container from scratch |
+| **Config** | Always | Toggles the configuration panel |
+| **Remove** | Stopped | Deletes the project and its container (with confirmation) |
+
+### Container Lifecycle
+
+Containers use a **stop/start** model. When you stop a container, everything inside it is preserved — installed packages, modified files, downloaded tools. Starting it again resumes where you left off.
+
+**Reset** removes the container and creates a fresh one. However, your Claude Code configuration (including OAuth tokens from `claude login`) is stored in a separate Docker volume and survives resets.
+
+Only **Remove** deletes everything, including the config volume and any stored credentials.
+
+---
+
+## Project Configuration
+
+Click **Config** on a selected project to expand the configuration panel. Settings can only be changed when the container is **stopped** (an orange warning box appears if the container is running).
+
+### Mounted Folders
+
+Each project mounts one or more host directories into the container. The mount appears at `/workspace/<mount-name>` inside the container.
+
+- Click **Browse** ("...") to change the host path
+- Edit the mount name to control where it appears inside `/workspace/`
+- Click **+** to add more folders, or **x** to remove one
+- Mount names must be unique and use only letters, numbers, dashes, underscores, and dots
+
+### SSH Keys
+
+Specify the path to your SSH key directory (typically `~/.ssh`). Keys are mounted read-only and copied into the container with correct permissions. This enables `git clone` via SSH inside the container.
+
+### Git Configuration
+
+- **Git Name / Email** — Sets `git config user.name` and `user.email` inside the container.
+- **Git HTTPS Token** — A personal access token (e.g., from GitHub) for HTTPS git operations. Stored securely in your OS keychain — never written to disk in plaintext.
+
+### Allow Container Spawning
+
+When enabled, the host Docker socket is mounted into the container so Claude Code can create sibling containers (e.g., for running databases, test environments). This is **off by default** for security.
+
+> Toggling this requires stopping and restarting the container to take effect.
+
+### Environment Variables
+
+Click **Edit** to open the environment variables modal. Add key-value pairs that will be injected into the container. Per-project variables override global variables with the same key.
+
+> Reserved prefixes (`ANTHROPIC_`, `AWS_`, `GIT_`, `HOST_`, `CLAUDE_`, `TRIPLE_C_`) are filtered out to prevent conflicts with internal variables.
+
+### Port Mappings
+
+Click **Edit** to map host ports to container ports. This is useful when Claude Code starts a web server or other service inside the container and you want to access it from your host browser.
+
+Each mapping specifies:
+- **Host Port** — The port on your machine (1–65535)
+- **Container Port** — The port inside the container (1–65535)
+- **Protocol** — TCP (default) or UDP
+
+### Claude Instructions
+
+Click **Edit** to write per-project instructions for Claude Code. These are written to `~/.claude/CLAUDE.md` inside the container and provide project-specific context. If you also have global instructions (in Settings), the global instructions come first, followed by the per-project instructions.
+
+---
+
+## AWS Bedrock Configuration
+
+To use Claude via AWS Bedrock instead of Anthropic's API, switch the auth mode to **Bedrock** on the project card.
+
+### Authentication Methods
+
+| Method | Fields | Use Case |
+|--------|--------|----------|
+| **Keys** | Access Key ID, Secret Access Key, Session Token (optional) | Direct credentials — simplest setup |
+| **Profile** | AWS Profile name | Uses `~/.aws/config` and `~/.aws/credentials` on the host |
+| **Token** | Bearer Token | Temporary bearer token authentication |
+
+### Additional Bedrock Settings
+
+- **AWS Region** — Required. The region where your Bedrock models are deployed (e.g., `us-east-1`).
+- **Model ID** — Optional. Override the default Claude model (e.g., `anthropic.claude-sonnet-4-20250514-v1:0`).
+
+### Global AWS Defaults
+
+In **Settings > AWS Configuration**, you can set defaults that apply to all Bedrock projects:
+
+- **AWS Config Path** — Path to your `~/.aws` directory. Click **Detect** to auto-find it.
+- **Default Profile** — Select from profiles found in your AWS config.
+- **Default Region** — Fallback region for projects that don't specify one.
+
+Per-project settings always override these global defaults.
+
+---
+
+## Settings
+
+Access global settings via the **Settings** tab in the sidebar.
+
+### Docker Settings
+
+- **Docker Status** — Connection status to the Docker daemon.
+- **Image Source** — Where to get the sandbox container image (Registry, Local Build, or Custom).
+- **Pull / Build Image** — Download or build the image. Progress streams in real time.
+- **Refresh** — Re-check Docker and image status.
+
+### Container Timezone
+
+Set the timezone for all containers (IANA format, e.g., `America/New_York`, `Europe/London`, `UTC`). Auto-detected from your host on first launch. This affects scheduled task timing inside containers.
+
+### Global Claude Instructions
+
+Instructions applied to **all** projects. Written to `~/.claude/CLAUDE.md` in every container, before any per-project instructions.
+
+### Global Environment Variables
+
+Environment variables applied to **all** project containers. Per-project variables with the same key take precedence.
+
+### Updates
+
+- **Current Version** — The installed version of Triple-C.
+- **Auto-check** — Toggle automatic update checks (every 24 hours).
+- **Check now** — Manually check for updates.
+
+When an update is available, a pulsing **Update** button appears in the top bar. Click it to see release notes and download links.
+
+---
+
+## Terminal Features
+
+### Multiple Sessions
+
+You can open multiple terminal sessions (even for the same project). Each session gets its own tab in the top bar. Click a tab to switch, or click the **x** on a tab to close it.
+
+### URL Detection
+
+When Claude Code prints a long URL (e.g., during `claude login`), Triple-C detects it and shows a toast notification at the top of the terminal with an **Open** button. Clicking it opens the URL in your default browser. The toast auto-dismisses after 30 seconds.
+
+Shorter URLs in terminal output are also clickable directly.
+
+### Image Paste
+
+You can paste images from your clipboard into the terminal (Ctrl+V / Cmd+V). The image is uploaded to the container and the file path is injected into the terminal input so Claude Code can reference it.
+
+### Terminal Rendering
+
+The terminal uses WebGL for hardware-accelerated rendering of the active tab. Inactive tabs fall back to canvas rendering to conserve GPU resources. The terminal automatically resizes when you resize the window.
+
+---
+
+## Scheduled Tasks (Inside the Container)
+
+Once inside a running container terminal, you can set up recurring or one-time tasks using `triple-c-scheduler`. Tasks run as separate Claude Code sessions.
+
+### Create a Recurring Task
+
+```bash
+triple-c-scheduler add --name "daily-review" --schedule "0 9 * * *" --prompt "Review open issues and summarize"
+```
+
+### Create a One-Time Task
+
+```bash
+triple-c-scheduler add --name "migrate-db" --at "2026-03-05 14:00" --prompt "Run database migrations"
+```
+
+One-time tasks automatically remove themselves after execution.
+
+### Manage Tasks
+
+```bash
+triple-c-scheduler list                    # List all tasks
+triple-c-scheduler enable --id abc123      # Enable a task
+triple-c-scheduler disable --id abc123     # Disable a task
+triple-c-scheduler remove --id abc123      # Delete a task
+triple-c-scheduler run --id abc123         # Trigger a task immediately
+triple-c-scheduler logs --id abc123        # View logs for a task
+triple-c-scheduler logs --tail 20          # View last 20 log entries (all tasks)
+triple-c-scheduler notifications           # View completion notifications
+triple-c-scheduler notifications --clear   # Clear notifications
+```
+
+### Cron Schedule Format
+
+Standard 5-field cron: `minute hour day-of-month month day-of-week`
+
+| Example | Meaning |
+|---------|---------|
+| `*/30 * * * *` | Every 30 minutes |
+| `0 9 * * 1-5` | 9:00 AM on weekdays |
+| `0 */2 * * *` | Every 2 hours |
+| `0 0 1 * *` | Midnight on the 1st of each month |
+
+### Working Directory
+
+By default, tasks run in `/workspace`. Use `--working-dir` to specify a different directory:
+
+```bash
+triple-c-scheduler add --name "test" --schedule "0 */6 * * *" --prompt "Run tests" --working-dir /workspace/my-project
+```
+
+---
+
+## What's Inside the Container
+
+The sandbox container (Ubuntu 24.04) comes pre-installed with:
+
+| Tool | Version | Purpose |
+|------|---------|---------|
+| Claude Code | Latest | AI coding assistant (the tool being sandboxed) |
+| Node.js | 22 LTS | JavaScript/TypeScript development |
+| pnpm | Latest | Fast Node.js package manager |
+| Python | 3.12 | Python development |
+| uv | Latest | Fast Python package manager |
+| ruff | Latest | Python linter/formatter |
+| Rust | Stable | Rust development (via rustup) |
+| Docker CLI | Latest | Container management (when spawning is enabled) |
+| git | Latest | Version control |
+| GitHub CLI (gh) | Latest | GitHub integration |
+| AWS CLI | v2 | AWS services and Bedrock |
+| ripgrep | Latest | Fast code search |
+| build-essential | — | C/C++ compiler toolchain |
+| openssh-client | — | SSH for git and remote access |
+
+You can install additional tools at runtime with `sudo apt install`, `pip install`, `npm install -g`, etc. Installed packages persist across container stops (but not across resets).
+
+---
+
+## Troubleshooting
+
+### Docker is "Not Available"
+
+- **Is Docker running?** Start Docker Desktop or the Docker daemon (`sudo systemctl start docker`).
+- **Permissions?** On Linux, ensure your user is in the `docker` group or the socket is accessible.
+- **Custom socket path?** If your Docker socket is not at the default location, set it in Settings. The app expects `/var/run/docker.sock` on Linux/macOS or `//./pipe/docker_engine` on Windows.
+
+### Image is "Not Found"
+
+- Click **Pull Image** or **Build Image** in Settings > Docker.
+- If pulling fails, check your network connection and whether you can reach the registry.
+- Try switching to **Local Build** as an alternative.
+
+### Container Won't Start
+
+- Check that the Docker image is "Ready" in Settings.
+- Verify that the mounted folder paths exist on your host.
+- Look at the error message displayed in red below the project card.
+
+### OAuth Login URL Not Opening
+
+- Triple-C detects long URLs printed by `claude login` and shows a toast with an **Open** button.
+- If the toast doesn't appear, try scrolling up in the terminal — the URL may have already been printed.
+- You can also manually copy the URL from the terminal output and paste it into your browser.
+
+### File Permission Issues
+
+- Triple-C automatically remaps the container user's UID/GID to match your host user, so files created inside the container should have the correct ownership on your host.
+- If you see permission errors, try resetting the container (stop, then click **Reset**).
+
+### Settings Won't Save
+
+- Most project settings can only be changed when the container is **stopped**. Stop the container first, make your changes, then start it again.
+- Some changes (like toggling Docker access or changing mounted folders) trigger an automatic container recreation on the next start.

+# TODO / Future Improvements
+
+## In-App Auto-Update via `tauri-plugin-updater`
+
+**Priority:** High
+**Status:** Planned
+
+Currently the app detects available updates via the Gitea API (`check_for_updates` command) but cannot apply them. Users must manually download and install the new version. On macOS and Linux this is a poor experience compared to Windows (where NSIS handles upgrades cleanly).
+
+### Recommended approach: `tauri-plugin-updater`
+
+Full in-app auto-update: detects, downloads, verifies, and applies updates seamlessly on all platforms. The user clicks "Update" and the app restarts with the new version.
+
+### Requirements
+
+1. **Generate a Tauri update signing key pair** (this is Tauri's own Ed25519 key, not OS code signing):
+   ```bash
+   npx @tauri-apps/cli signer generate -w ~/.tauri/triple-c.key
+   ```
+   Set `TAURI_SIGNING_PRIVATE_KEY` and `TAURI_SIGNING_PRIVATE_KEY_PASSWORD` in CI.
+
+2. **Add `tauri-plugin-updater`** to Rust and JS dependencies.
+
+3. **Create an update endpoint** that returns Tauri's expected JSON format:
+   ```json
+   {
+     "version": "v0.1.100",
+     "notes": "Changelog here",
+     "pub_date": "2026-03-01T00:00:00Z",
+     "platforms": {
+       "darwin-x86_64": { "signature": "...", "url": "https://..." },
+       "darwin-aarch64": { "signature": "...", "url": "https://..." },
+       "linux-x86_64": { "signature": "...", "url": "https://..." },
+       "windows-x86_64": { "signature": "...", "url": "https://..." }
+     }
+   }
+   ```
+   This could be a static JSON file uploaded alongside release assets, or a small API that reads from Gitea releases and reformats.
+
+4. **Configure the updater** in `tauri.conf.json`:
+   ```json
+   "plugins": {
+     "updater": {
+       "endpoints": ["https://repo.anhonesthost.net/...update-endpoint..."],
+       "pubkey": "<public key from step 1>"
+     }
+   }
+   ```
+
+5. **Add frontend UI** for the update prompt (replace or enhance the existing update check flow).
+
+6. **Update CI pipeline** to:
+   - Sign bundles with the Tauri key during build
+   - Upload `.sig` files alongside installers
+   - Generate/upload the update endpoint JSON
+

+const SCHEDULER_INSTRUCTIONS: &str = r#"## Scheduled Tasks
+
+This container supports scheduled tasks via `triple-c-scheduler`. You can set up recurring or one-time tasks that run as separate Claude Code agents.
+
+### Commands
+- `triple-c-scheduler add --name "NAME" --schedule "CRON" --prompt "TASK"` — Add a recurring task
+- `triple-c-scheduler add --name "NAME" --at "YYYY-MM-DD HH:MM" --prompt "TASK"` — Add a one-time task
+- `triple-c-scheduler list` — List all scheduled tasks
+- `triple-c-scheduler remove --id ID` — Remove a task
+- `triple-c-scheduler enable --id ID` / `triple-c-scheduler disable --id ID` — Toggle tasks
+- `triple-c-scheduler logs [--id ID] [--tail N]` — View execution logs
+- `triple-c-scheduler run --id ID` — Manually trigger a task immediately
+- `triple-c-scheduler notifications [--clear]` — View or clear completion notifications
+
+### Cron format
+Standard 5-field cron: `minute hour day-of-month month day-of-week`
+Examples: `*/30 * * * *` (every 30 min), `0 9 * * 1-5` (9am weekdays), `0 */2 * * *` (every 2 hours)
+
+### One-time tasks
+Use `--at "YYYY-MM-DD HH:MM"` instead of `--schedule`. The task automatically removes itself after execution.
+
+### Working directory
+Use `--working-dir /workspace/project` to set where the task runs (default: /workspace).
+
+### Checking results
+After tasks run, check notifications with `triple-c-scheduler notifications` and detailed output with `triple-c-scheduler logs`.
+
+### Timezone
+Scheduled times use the container's configured timezone (check with `date`). If no timezone is configured, UTC is used."#;
