Features: **project groups** (up to 5 projects per group, horizontal layout, adaptive viewport count), **per-project Claude sessions** with session continuity, **team agents panel** (compact subagent cards), **terminal tabs** (shell/SSH/agent per project), agent panes with structured output, tree visualization with subtree cost and session resume, **subagent/agent-teams support**, **multi-machine support** (bterminal-relay WebSocket server + RemoteManager), **Claude profile/account switching** (switcher-claude integration), **skill discovery and autocomplete** (type `/` in agent prompt), SSH session management, ctx context database viewer, SQLite session persistence with layout restore, live markdown file viewer with Shiki syntax highlighting, 17 themes in 3 groups (4 Catppuccin + 7 Editor + 6 Deep Dark: Tokyo Night, Gruvbox Dark, Ayu Dark, Poimandres, Vesper, Midnight), **global font controls** (separate UI font [sans-serif] + terminal font [monospace] with live preview), .deb + AppImage packaging, GitHub Actions CI, 138 vitest + 36 cargo tests. Branch `v2-mission-control`. See [docs/v3-task_plan.md](docs/v3-task_plan.md) for v3 architecture.

## Features

- **SSH sessions** — saved configs (host, port, user, key, folder, color), CRUD with side panel
- **Claude Code sessions** — saved Claude Code configs with sudo, resume, skip-permissions and initial prompt
- **SSH macros** — multi-step macros (text, key, delay) assigned to sessions, run from sidebar
- **Tabs** — multiple terminals in tabs, Ctrl+T new, Ctrl+Shift+W close, Ctrl+PageUp/Down switch
- **Sudo askpass** — Claude Code with sudo: password entered once, temporary askpass helper, auto-cleanup
- **Folder grouping** — SSH and Claude Code sessions can be grouped in folders on the sidebar
- **ctx — Context manager** — SQLite-based cross-session context database for Claude Code projects
- **Catppuccin Mocha** — full theme: terminal, sidebar, tabs, session colors

## Installation

```bash
git clone https://github.com/DexterFromLab/BTerminal.git
cd BTerminal
./install.sh
```

The installer will:
1. Install system dependencies (python3-gi, GTK3, VTE)
2. Copy files to `~/.local/share/bterminal/`
3. Create symlinks: `bterminal` and `ctx` in `~/.local/bin/`
4. Initialize context database at `~/.claude-context/context.db`
5. Add desktop entry to application menu

### v2 Installation (Tauri — build from source)

Requires Node.js 20+, Rust 1.77+, and system libraries (WebKit2GTK 4.1, GTK3, etc.).

```bash
git clone https://github.com/DexterFromLab/BTerminal.git
cd BTerminal
./install-v2.sh
```

The installer checks all dependencies, offers to install missing system packages via apt, builds the Tauri app, and installs the binary as `bterminal-v2` in `~/.local/bin/`.

Pre-built .deb and AppImage packages are available from [GitHub Releases](https://github.com/DexterFromLab/BTerminal/releases) (built via CI on version tags).

### v1 Manual dependency install (Debian/Ubuntu/Pop!_OS)

```bash
sudo apt install python3-gi gir1.2-gtk-3.0 gir1.2-vte-2.91
```

## Usage

```bash
bterminal
```

## Context Manager (ctx)

`ctx` is a SQLite-based tool for managing persistent context across Claude Code sessions.

```bash
ctx init myproject "Project description" /path/to/project
ctx get myproject                    # Load full context (shared + project)
ctx set myproject key "value"        # Save a context entry
ctx shared set preferences "value"   # Save shared context (available in all projects)
ctx summary myproject "What was done" # Save session summary
ctx search "query"                   # Full-text search across everything
ctx list                             # List all projects
ctx history myproject                # Show session history
ctx --help                           # All commands
```

### Integration with Claude Code

Add a `CLAUDE.md` to your project root:

```markdown
On session start, load context:
  ctx get myproject

Save important discoveries: ctx set myproject <key> <value>
Before ending session: ctx summary myproject "<what was done>"
```

Claude Code reads `CLAUDE.md` automatically and will maintain the context database.

## Configuration

Config files in `~/.config/bterminal/`:

| File | Description |
|------|-------------|
| `sessions.json` | Saved SSH sessions + macros |
| `claude_sessions.json` | Saved Claude Code configs |

Context database: `~/.claude-context/context.db`

## Keyboard Shortcuts

| Shortcut | Action |
|----------|--------|
| `Ctrl+T` | New tab (local shell) |
| `Ctrl+Shift+W` | Close tab |
| `Ctrl+Shift+C` | Copy |
| `Ctrl+Shift+V` | Paste |
| `Ctrl+PageUp/Down` | Previous/next tab |

## Multi-Machine Support (v2)

BTerminal v2 can manage agents and terminals running on remote machines via the `bterminal-relay` binary.

### Architecture

```
BTerminal (Controller) --WebSocket--> bterminal-relay (Remote Machine)
                                      ├── PtyManager (remote terminals)
                                      └── SidecarManager (remote agents)
```

### Running the Relay

On each remote machine:

```bash
# Build the relay binary
cd v2 && cargo build --release -p bterminal-relay

# Start with token auth
./target/release/bterminal-relay --port 9750 --token <secret>

# Dev mode (allow unencrypted ws://)
./target/release/bterminal-relay --port 9750 --token <secret> --insecure
```

Add remote machines in BTerminal Settings > Remote Machines (label, URL, token). Remote panes auto-group by machine label in the sidebar. Connections automatically reconnect with exponential backoff (1s-30s cap) on disconnect.

See [docs/multi-machine.md](docs/multi-machine.md) for full architecture details.

## Telemetry (v2)

BTerminal supports OpenTelemetry tracing with optional export to Tempo + Grafana.

```bash
# Start the tracing stack
cd docker/tempo && docker compose up -d
# Grafana at http://localhost:9715

# Run BTerminal with OTLP export enabled
BTERMINAL_OTLP_ENDPOINT=http://localhost:4318 npm run tauri dev
```

Without `BTERMINAL_OTLP_ENDPOINT`, telemetry falls back to console-only tracing (no network calls). Key Tauri commands (PTY, agent, remote) are instrumented with `#[tracing::instrument]`. Frontend events (agent lifecycle, errors, cost) route to Rust tracing via IPC bridge.
