# Bulwark Status Line

Configure the Bulwark multi-line status line for Claude Code.

---

## When to Use

Use this skill when:
- Setting up the Bulwark status line for the first time (`init`)
- Switching between status line presets (`minimal`, `developer`, `cost`)
- User asks to configure or customize the status line display

---

## Invocation

This skill can be invoked two ways:

| Method | Example |
|--------|---------|
| **Command** | `/bulwark-statusline minimal` |
| **Conversational** | "Change my status line to minimal" |

When invoked, **you (Claude) execute the steps** using the tools declared above (Bash, Read, Edit).

---

## Usage

```
/bulwark-statusline init        # Install with default (developer) preset
/bulwark-statusline minimal     # Switch to minimal preset (1 line)
/bulwark-statusline developer   # Switch to developer preset (3 lines)
/bulwark-statusline cost        # Switch to cost preset (2 lines)
```

### Argument Handling

The subcommand is passed via `$1`:

```
/bulwark-statusline init
                     ^^^^
                     $1 = "init"
```

Parse `$1` and execute the corresponding subcommand below.

---

## Subcommand: init

Install the Bulwark status line for first-time setup.

**Execute these steps:**

1. **Bash**: Create config directory
   ```bash
   mkdir -p ~/.bulwark
   ```

2. **Bash**: Copy default config template
   ```bash
   cp "${CLAUDE_PROJECT_DIR}/skills/bulwark-statusline/templates/statusline-default.yaml" ~/.bulwark/statusline.yaml
   ```

3. **Spawn statusline-setup agent** to update settings.json:
   ```
   Task(subagent_type="statusline-setup", prompt="
     GOAL: Add statusLine configuration to .claude/settings.json
     TARGET: .claude/settings.json (project level)

     EXACT JSON to add at top level of settings.json:
     {
       \"statusLine\": {
         \"type\": \"command\",
         \"command\": \"${CLAUDE_PROJECT_DIR}/skills/bulwark-statusline/scripts/statusline.sh\"
       }
     }

     If .claude/settings.json does not exist, create it with just this content.
     If it exists, merge the statusLine key into the existing JSON, preserving all other keys.
   ")
   ```

4. **Display to user**: "Status line installed. Restart session to activate."
