CLI tool for launching multiple Claude Code terminals with interactive [subagents](https://docs.anthropic.com/en/docs/claude-code/sub-agents), headless persistence, and real-time communication via [hooks](https://docs.anthropic.com/en/docs/claude-code/hooks). Works on Mac, Linux, Windows, and Android with zero dependencies.

![Claude Code Hook Comms Example](https://raw.githubusercontent.com/aannoo/claude-hook-comms/main/screencapture.gif)

## 🥦 Usage

**Run without installing** ([uv](https://docs.astral.sh/uv/#installation))
```bash
uvx hcom open 2
```

**Install** (optional)
```bash
pip install hcom
hcom open 2
```

| Commands |  |
|---------|-------------|
| `hcom open [n]` | Launch `n` instances or named agents |
| `hcom watch` | View live dashboard and messaging |
| `hcom clear` | Clear and start new conversation |
| `hcom cleanup` | Safely remove hcom hooks, preserving your project settings |


## 🦆 What It Does

`hcom open` adds hooks to the `.claude/settings.local.json` file in the current folder and launches terminals with claude code that remain active, waiting to respond to messages in the shared chat. Normal Claude Code opened with `claude` remains unaffected by hcom.

### Subagents in their own terminal
```bash
# Launch subagents from your .claude/agents
hcom open planner code-writer reviewer
```

### Persistent headless instances
```bash
# Launch one headless instance (default 30min timeout)
hcom open -p
```

### Groups and direct messages
```bash
hcom open --prefix cool  # Creates cool-hovoa7
hcom open --prefix cool  # Creates cool-homab8
hcom send '@cool hi, you are cool'
hcom send '@homab8 hi, you are cooler'
```

### Persistent thinking mode
```bash
# Thinking mode maintains for entire session
HCOM_INITIAL_PROMPT="ultrathink and do x" hcom open
# Every new message reply uses ultrathink
```

<summary><strong>🦖 Configuration</strong></summary>

### Configuration

Settings can be changed two ways:

#### Method 1: Environment variable (temporary, per-command/instance)


```bash
HCOM_INSTANCE_HINTS="always update chat with progress" hcom open nice-subagent-but-not-great-with-updates
```

#### Method 2: Config file (persistent, affects all instances)

### Config File Location

`~/.hcom/config.json`

| Setting | Default | Environment Variable | Description |
|---------|---------|---------------------|-------------|
| `wait_timeout` | 1800 | `HCOM_WAIT_TIMEOUT` | How long instances wait for messages (seconds) |
| `max_message_size` | 1048576 | `HCOM_MAX_MESSAGE_SIZE` | Maximum message length (1MB) |
| `max_messages_per_delivery` | 50 | `HCOM_MAX_MESSAGES_PER_DELIVERY` | Messages delivered per batch |
| `sender_name` | "bigboss" | `HCOM_SENDER_NAME` | Your name in chat |
| `sender_emoji` | "🐳" | `HCOM_SENDER_EMOJI` | Your emoji icon |

| `terminal_command` | null | `HCOM_TERMINAL_COMMAND` | Custom terminal command (see Terminal Options) |
| `cli_hints` | "" | `HCOM_CLI_HINTS` | Extra text added to CLI outputs |
| `instance_hints` | "" | `HCOM_INSTANCE_HINTS` | Extra text added to instance messages |
| `auto_watch` | true | `HCOM_AUTO_WATCH` | Auto-launch watch dashboard after open |
| `env_overrides` | {} | - | Additional environment variables for Claude Code |

### Examples

```bash
# Change your name for one command
HCOM_SENDER_NAME="coolguy" hcom send "LGTM!"

# Make instances timeout after 60 seconds instead of 30 minutes
HCOM_WAIT_TIMEOUT=60 hcom open 3

# Custom welcome message
HCOM_FIRST_USE_TEXT="Debug session for issue #123" hcom open 2

# Bigger delivery batches
HCOM_MAX_MESSAGES_PER_DELIVERY=100 hcom watch --logs
```

**Windows PowerShell**:
```powershell
# Set environment variables in PowerShell
$env:HCOM_TERMINAL_MODE="same_terminal"; hcom open agent-name
$env:HCOM_WAIT_TIMEOUT="60"; hcom open 3
$env:HCOM_INITIAL_PROMPT="go home buddy!"; hcom open
```

### Status Indicators

When running `hcom watch`, each instance shows its current state:

- ▶ **active** (green) - Working (processing/executing)
- ▷ **delivered** (cyan) - Just received a message
- ◉ **waiting** (blue) - Waiting for messages
- ■ **blocked** (yellow) - Permission request pending
- ○ **inactive** (red) - Timed out/disconnected
- ○ **unknown** (gray) - No status data
- **(bg)** suffix - Instance running in background headless mode

<summary><strong>🎲 How It Works</strong></summary>

### Hooks!

hcom adds hooks to your project directory's `.claude/settings.local.json`:

1. **Sending**: Claude agents use `eval $HCOM send "message"` internally (you use `hcom send` from terminal or dashboard)
2. **Receiving**: Other Claudes get notified via Stop hook or immediate delivery after sending
3. **Waiting**: Stop hook keeps Claude in a waiting state for new messages

- **Identity**: Each instance gets a unique name based on session ID (e.g., "hovoa7")
- **Persistence**: Names persist across `--resume` maintaining conversation context
- **Status Detection**: Notification hook tracks permission requests and activity
- **Agents**: When you run `hcom open researcher`, it loads an interactive Claude session with a system prompt from `.claude/agents/researcher.md` (local) or `~/.claude/agents/researcher.md` (global). Specified `model:` and `tools:` are carried over

### Architecture
- **Single conversation** - All instances share one global conversation
- **Opt-in participation** - Only Claude Code instances launched with `hcom open` join the chat
- **@-mention filtering** - Target messages to specific instances or teams

### File Structure
```plaintext
~/.hcom/

<summary><strong>🥔 Terminal Options</strong></summary>

### Terminal Mode

Configure terminal behavior in `~/.hcom/config.json`:
- `"terminal_mode": "new_window"` - Opens new terminal window(s) (default)
- `"terminal_mode": "same_terminal"` - Opens in current terminal

#### Running in current terminal temporarily
```bash
# For single instances
HCOM_TERMINAL_MODE=same_terminal hcom open
```

### Default Terminals

- **macOS**: Terminal.app
- **Linux**: gnome-terminal, konsole, or xterm
- **Windows & WSL**: Windows Terminal / Git Bash
- **Android**: Termux


### Custom Terminals

Configure `terminal_command` in `~/.hcom/config.json` (permanent) or environment variables (temporary).

#### How to use this

The `{script}` placeholder is replaced by HCOM with the path to a temporary bash script that launches Claude Code.

Your custom command just needs to:
1. Accept `{script}` as a placeholder that will be replaced with a script path
2. Execute that script with bash

Example template: `your_terminal_command --execute "bash {script}"`

### Custom Terminal Examples

Working (processing/executing)\n- \u25b7 **delivered** (cyan) - Just received a message\n- \u25c9 **waiting** (blue) - Waiting for messages\n- \u25a0 **blocked** (yellow) - Permission request pending\n- \u25cb **inactive** (red) - Timed out/disconnected\n- \u25cb **unknown** (gray) - No status data\n- **(bg)** suffix - Instance running in background headless mode\n\n</details>\n\n<details>\n<summary><strong>\ud83c\udfb2 How It Works</strong></summary>\n\n### Hooks!\n\nhcom adds hooks to your project directory's `.claude/settings.local.json`:\n\n1. **Sending**: Claude agents use `eval $HCOM send \"message\"` internally (you use `hcom send` from terminal or dashboard)\n2. **Receiving**: Other Claudes get notified via Stop hook or immediate delivery after sending\n3. **Waiting**: Stop hook keeps Claude in a waiting state for new messages\n\n- **Identity**: Each instance gets a unique name based on session ID (e.g., \"hovoa7\")\n- **Persistence**: Names persist across `--resume` maintaining conversation context\n- **Status Detection**: Notification hook tracks permission requests and activity\n- **Agents**: When you run `hcom open researcher`, it loads an interactive Claude session with a system prompt from `.claude/agents/researcher.md` (local) or `~/.claude/agents/researcher.md` (global). Specified `model:` and `tools:` are carried over\n\n### Architecture\n- **Single conversation** - All instances share one global conversation\n- **Opt-in participation** - Only Claude Code instances launched with `hcom open` join the chat\n- **@-mention filtering** - Target messages to specific instances or teams\n\n### File Structure\n```plaintext\n~/.hcom/                             \n\u251c\u2500\u2500 hcom.log       # Conversation log\n\u251c\u2500\u2500 instances/     # Instance tracking\n\u251c\u2500\u2500 logs/          # Background process logs\n\u251c\u2500\u2500 config.json    # Configuration\n\u2514\u2500\u2500 archive/       # Archived sessions\n\nyour-project/  \n\u2514\u2500\u2500 .claude/\n    \u2514\u2500\u2500 settings.local.json  # hcom hooks\n```\n\n</details>\n\n\n<details>\n<summary><strong>\ud83e\udd54 Terminal Options</strong></summary>\n\n### Terminal Mode\n\nConfigure terminal behavior in `~/.hcom/config.json`:\n- `\"terminal_mode\": \"new_window\"` - Opens new terminal window(s) (default)\n- `\"terminal_mode\": \"same_terminal\"` - Opens in current terminal\n\n#### Running in current terminal temporarily\n```bash\n# For single instances\nHCOM_TERMINAL_MODE=same_terminal hcom open\n```\n\n### Default Terminals\n\n- **macOS**: Terminal.app\n- **Linux**: gnome-terminal, konsole, or xterm\n- **Windows & WSL**: Windows Terminal / Git Bash\n- **Android**: Termux\n\n\n### Custom Terminals\n\nConfigure `terminal_command` in `~/.hcom/config.json` (permanent) or environment variables (temporary).\n\n#### How to use this\n\nThe `{script}` placeholder is replaced by HCOM with the path to a temporary bash script that launches Claude Code.\n\nYour custom command just needs to:\n1. Accept `{script}` as a placeholder that will be replaced with a script path\n2. Execute that script with bash\n\nExample template: `your_terminal_command --execute \"bash {script}\"`\n\n### Custom Terminal Examples\n\n#### iTerm2\n```json\n\"terminal_command\": \"open -a iTerm {script}\"\n```\n\n#### [ttab](https://github.com/mklement0/ttab) (new tab instead of new window in Terminal.app)\n```json\n\"terminal_command\": \"ttab {script}\"\n```\n\n#### [wttab](https://github.com/lalilaloe/wttab) (new tab in Windows Terminal)\n```json\n\"terminal_command\": \"wttab {script}\"\n```\n\n#### More\n```json\n# WezTerm Linux/Windows\n\"terminal_command\": \"wezterm start -- bash {script}\"\n\n# Tabs from within WezTerm\n\"terminal_command\": \"wezterm cli spawn -- bash {script}\"\n\n# WezTerm macOS:\n\"terminal_command\": \"open -n -a WezTerm.app --args start -- bash {script}\"\n\n# Tabs from within WezTerm macOS\n\"terminal_command\": \"/Applications/WezTerm.app/Contents/MacOS/wezterm cli spawn -- bash {script}\"\n\n# Wave Terminal Mac/Linux/Windows. From within Wave Terminal:\n\"terminal_command\": \"wsh run -- bash {script}\"\n\n# Alacritty macOS:\n\"terminal_command\": \"open -n -a Alacritty.app --args -e bash {script}\"\n\n# Alacritty Linux:\n\"terminal_command\": \"alacritty -e bash {script}\"\n\n# Kitty macOS:\n\"terminal_command\": \"open -n -a kitty.app --args {script}\"\n\n# Kitty Linux\n\"terminal_command\": \"kitty {script}\"\n```\n\n#### tmux\n```json\n\"terminal_command\": \"tmux new-window -n hcom {script}\"\n```\n```bash\n# tmux commands work inside tmux, start a session with:\ntmux new-session 'hcom open 3' # each instance opens in new tmux window\n\n# Or one time split-panes:\n# Start tmux with split panes and 3 claude instances in hcom chat\nHCOM_TERMINAL_COMMAND=\"tmux split-window -h {script}\" hcom open 3\n```\n\n### Android (Termux)\n\n1. Install [Termux](https://f-droid.org/packages/com.termux/) from F-Droid (not Google Play)\n2. Setup:\n   ```bash\n   pkg install python nodejs\n   npm install -g @anthropic-ai/claude-cli\n   pip install hcom\n   ```\n3. Enable:\n   ```bash\n   echo \"allow-external-apps=true\" >> ~/.termux/termux.properties\n   termux-reload-settings\n   ```\n4. Enable: \"Display over other apps\" permission for visible terminals\n\n5. Run: `hcom open`\n\n---\n\n</details>\n\n\n<details>\n<summary><strong>\u2697\ufe0f Remove</strong></summary>\n\n\n### Archive Conversation / Start New\n```bash\nhcom clear\n```\n\n### Kill Running Instances\n```bash\n# Kill specific instance\nhcom kill hovoa7\n\n# Kill all instances\nhcom kill --all\n```\n\n### Remove HCOM hooks from current directory\n```bash\nhcom cleanup\n```\n\n### Remove HCOM hooks from all directories\n```bash\nhcom cleanup --all\n```\n\n### Remove hcom Completely\n1.
