# /mode - Daemon Mode Management

## Description

View or change the daemon's operating mode. Supports `default` (normal operation) and `unattended` (blocks Stop events to keep Claude working autonomously).

## Usage

```claude-code
# Show current mode
/mode
/mode get

# Switch to unattended mode (blocks Stop events)
/mode unattended

# Switch to unattended with custom task message
/mode unattended finish the release and run all tests

# Switch back to default mode
/mode default
```

## Modes

| Mode         | Behaviour                                                                      |
| ------------ | ------------------------------------------------------------------------------ |
| `default`    | Normal operation - all handlers process events as configured                   |
| `unattended` | Blocks Stop events unconditionally to keep Claude working without interruption |

## What Unattended Mode Does

When enabled, a **mode interceptor** runs before the handler chain on every event:

- **Stop events**: Blocked with a DENY response instructing Claude to continue working
- **SubagentStop events**: NOT blocked (subagents should stop normally)
- **All other events**: Pass through to normal handler chain unchanged

The interceptor includes re-entry protection (checks `stop_hook_active` flag) to prevent infinite loops.

## Custom Messages

When switching to unattended mode, you can include a custom message that gets appended to the block reason. This lets you give Claude specific instructions about what to work on:

```claude-code
/mode unattended complete all remaining tasks in the plan
```

The message appears in the Stop event denial reason, so Claude sees it when it tries to stop.

## Python Path Detection

There is no interpreter to detect. The deployed wrapper resolves the
fingerprint-keyed venv itself, and lives at the same place relative to the
daemon root in both install modes:

```bash
# self-install (daemon development)
./bin/hooks-daemon <command>

# normal install
.claude/hooks-daemon/bin/hooks-daemon <command>
```

## IPC Protocol

The skill communicates with the daemon via Unix socket system requests:

**Get mode:**

```json
{"event": "_system", "hook_input": {"action": "get_mode"}}
```

**Set mode:**

```json
{"event": "_system", "hook_input": {"action": "set_mode", "mode": "unattended", "custom_message": "optional"}}
```

## Output

### On get mode:

```
Mode: default
```

### On set unattended:

```
Mode: unattended (changed)
Message: finish the release
```

### On set default:

```
Mode: default (changed)
```

## Requirements

- Daemon must be running
- Python venv must be available (self-install or normal install)
