# Status Line Agent Display + Keybind Fix

## Goal

1. Display `[personal-assistant] Opus | 45% context` in Claude Code status line
2. Fix Super+Shift+C keybind (terminal closes immediately)

## Root Cause: Keybind Issue

The `pa-mode` script creates a **detached** tmux session (`-d` flag) then attaches separately. This doesn't work well with `omarchy-launch-tui`. The working pattern uses `tmux -A` (attach-or-create in one step).

## Implementation

### Task 1: Create Status Line Script

**Create:** `~/.claude/automation/statusline.sh`

```bash
#!/usr/bin/env bash
input=$(cat)

AGENT="${CLAUDE_AGENT:-}"
MODEL=$(echo "$input" | jq -r '.model.display_name // "?"')

# Calculate context percentage
CONTEXT_PCT="?"
usage=$(echo "$input" | jq '.context_window.current_usage // empty')
if [ -n "$usage" ]; then
  current=$(echo "$usage" | jq '.input_tokens + .cache_creation_input_tokens + .cache_read_input_tokens')
  size=$(echo "$input" | jq '.context_window.context_window_size')
  if [ "$size" -gt 0 ] 2>/dev/null; then
    CONTEXT_PCT=$((current * 100 / size))
  fi
fi

if [ -n "$AGENT" ]; then
  echo "[$AGENT] $MODEL | ${CONTEXT_PCT}% context"
else
  echo "$MODEL | ${CONTEXT_PCT}% context"
fi
```

### Task 2: Configure Status Line in Settings

**Modify:** `~/.claude/settings.json`

Add:
```json
{
  "statusLine": {
    "type": "command",
    "command": "~/.claude/automation/statusline.sh"
  }
}
```

### Task 3: Fix pa-mode Script

**Modify:** `~/.claude/automation/pa-mode`

Key changes:
1. Export `CLAUDE_AGENT=personal-assistant` before launching
2. Use `tmux new-session -A` (attach-or-create) instead of `-d` + separate attach
3. Remove the separate `attach_session` flow

New `create_or_attach_session()` function:
```bash
create_or_attach_session() {
    local session_id
    session_id=$(get_session_id)
    local history_file="$HISTORY_DIR/${session_id}.jsonl"

    # If session doesn't exist, record it in index
    if ! tmux has-session -t "$SESSION_NAME" 2>/dev/null; then
        local tmp_file
        tmp_file=$(mktemp)
        jq --arg id "$session_id" --arg started "$(date -Iseconds)" \
            '.sessions += [{"id": $id, "started": $started, "ended": null, "summarized": false, "topics": []}]' \
            "$INDEX_FILE" > "$tmp_file" && mv "$tmp_file" "$INDEX_FILE"
    fi

    # Export for status line, then attach-or-create
    export CLAUDE_AGENT=personal-assistant
    exec tmux new-session -A -s "$SESSION_NAME" -c "$HOME" \
        "PA_SESSION_ID='$session_id' PA_HISTORY_FILE='$history_file' CLAUDE_AGENT=personal-assistant claude --dangerously-skip-permissions --agent personal-assistant"
}
```

Note: Using `exec` replaces the shell process with tmux, keeping the terminal open.

### Task 4: Verify Hyprland Keybind

**File:** `~/.config/hypr/bindings.conf` (line 34)

Current (should work after pa-mode fix):
```
bindd = SUPER SHIFT, C, PA Agent Mode, exec, omarchy-launch-tui /home/will/.claude/automation/pa-mode
```

No changes needed if pa-mode fix works. If still broken, fallback to:
```
bindd = SUPER SHIFT, C, PA Agent Mode, exec, uwsm-app -- xdg-terminal-exec -e /home/will/.claude/automation/pa-mode
```

## Files to Modify

| File | Action |
|------|--------|
| `~/.claude/automation/statusline.sh` | Create |
| `~/.claude/settings.json` | Add statusLine config |
| `~/.claude/automation/pa-mode` | Fix session creation, add CLAUDE_AGENT export |
| `~/.config/hypr/bindings.conf` | Maybe adjust if fix doesn't work |

## Testing

1. Run `pa-mode` from terminal - should open tmux with claude
2. Check status line shows `[personal-assistant] Opus | X% context`
3. Press Super+Shift+C - terminal should stay open with PA session
4. Detach (Ctrl+B, D), press Super+Shift+C again - should reattach

## Commits

1. `feat: add status line script with agent display`
2. `fix: pa-mode keybind issue - use tmux -A and exec`
