Architecture

Component Pattern

All components follow Pi's TUI pattern:

interface Component {
  render(width: number): string[];  // Return array of lines
  invalidate(): void;                // Clear cache
  handleInput?(data: string): void;  // Optional keyboard input
}

Caching Strategy

Components cache rendered output for performance:

private cachedWidth?: number;
private cachedLines?: string[];

render(width: number): string[] {
  if (this.cachedLines && this.cachedWidth === width) {
    return this.cachedLines;
  }
  // ... render logic ...
  this.cachedWidth = width;
  this.cachedLines = lines;
  return lines;
}

invalidate(): void {
  this.cachedWidth = undefined;
  this.cachedLines = undefined;
}

Theme Integration

All components accept theme: Theme and use semantic colors:

this.theme.fg("accent", text)     // Highlighted text
this.theme.fg("success", text)    // Positive status
this.theme.fg("warning", text)    // Warning status
this.theme.fg("error", text)      // Error/critical
this.theme.fg("dim", text)        // Muted/helper text
this.theme.fg("border", text)     // Borders/separators

Keyboard Handling

Use matchesKey() for consistent keyboard detection:

import { matchesKey, Key } from "@mariozechner/pi-tui";

handleInput(data: string): void {
  if (matchesKey(data, Key.up)) {
    // Handle up arrow
  } else if (matchesKey(data, Key.enter)) {
    // Handle enter
  } else if (matchesKey(data, Key.escape)) {
    // Handle escape
  }
}

Integration with Orchestrator

The Progress Indicator is designed to show real-time updates during parallel sub-agent execution:

// In orchestrator.ts (future integration)
async function runParallelSubagents(tasks, onProgress) {
  const scouts = tasks.map(t => ({
    name: t.agent,
    status: "pending",
    progress: 0,
  }));

  const indicator = new ProgressIndicator(scouts, theme);
  ctx.ui.setWidget("dex-progress", (tui, theme) => ({
    render: (w) => indicator.render(w),
    invalidate: () => indicator.invalidate(),
  }));

  const results = await Promise.all(
    tasks.map(async (task) => {
      indicator.updateScout(task.agent, { status: "running" });
      tui.requestRender();

      const result = await runSubagent(task.agent, task.task);

      indicator.updateScout(task.agent, {
        status: "complete",
        progress: 100,
        duration: result.durationMs,
      });
      tui.requestRender();

      return result;
    })
  );

  ctx.ui.setWidget("dex-progress", undefined);
  return results;
}

Next Steps

Phase 5: Real Integration

Now that the UI components are built and tested, integrate them with actual data:

1. Wire up /plan-wizard to real scout data

   • Call orchestrateDailyPlan() to gather context
   • Pass actual calendar/task/week data to wizard
   • Save generated plan to daily note

2. Wire up /review-wizard to real data

   • Load completed tasks from today's work
   • Get open tasks from 03-Tasks/Tasks.md
   • Integrate with commitment-detector for real commitments
   • Save review to daily note

3. Add Progress Indicator to orchestrator

   • Show during parallel sub-agent execution
   • Real-time updates as scouts complete
   • Remove mock delays

4. Week Progress in Footer

   • Read actual week priorities from 02-Week_Priorities/
   • Calculate progress based on completed tasks
   • Update footer automatically during session

5. Career Gauge from Real Data

   • Read career evidence from 05-Areas/Career/Evidence/
   • Calculate competency scores from evidence
   • Integrate with /career-coach skill

Phase 6: Polish & Refinement

• Add search/filter to task board
• Add task editing modal
• Customize wizard with user preferences
• Add visual animations (smooth progress updates)
• Theme customization
• Keyboard shortcut hints
• Help overlays
