Implement rich CLI UI with Ink components and gradients by Copilot · Pull Request #9 · codervisor/leanspec

Copilot · 2025-11-03T07:46:28Z

Implements spec 013-cli-ui-ux-optimization to bring Python rich-style UI to the CLI. All commands now use Ink/React for consistent, beautiful rendering.

Component Library

Created reusable UI primitives in src/components/ui/:

Panel: Rounded borders (╭─╮╰─╯) with titles
Table: Auto-sized columns with alignment
KeyValueList: Aligned metadata display
StatusBadge: Emoji + color indicators
Card: Metadata cards with borders

Command Enhancements

Stats: Multi-panel dashboard with bar charts

// Before: Plain text lists
// After: Panels with visual bars
╭─ 📊 Status Distribution ──────╮
│ 📅 Planned  ━━━━━━━━━ 6      │
│ 🔨 Progress ━━━ 2             │
╰────────────────────────────────╯

Board: Enhanced kanban with hashtag tags, emoji priorities

// Before: [ux, polish] priority: medium
// After:  #ux #polish · 🟠 medium

List: Converted from console.log to Ink with tree structure

// Before: Simple indented text
// After:  Tree with metadata
📂 20251103/
  ├─ 001-feature/
     ✅ 🟡 high · [#core #ux]

Visual Design

Rainbow gradient titles via ink-gradient
Bar charts with Unicode (━━━) for distributions
Rounded corners for softer appearance
Semantic color coding (cyan/yellow/green/magenta)
Tree characters (├─) for hierarchy

Dependencies

Added Ink ecosystem libraries:

ink-gradient ^3.0.0 (gradients)
ink-table, ink-spinner, ink-select-input, ink-text-input, ink-progress-bar (future interactive features)

All 106 tests pass. Zero security vulnerabilities.

+    const headerLength = col.header.length;
+    const maxContentLength = Math.max(
+      ...rows.map(row => {
+        const value = Object.values(row)[idx];


Accessing row values by index using Object.values(row)[idx] is fragile and assumes column order matches property order. Consider using a key property in TableColumn to explicitly map columns to row properties by key name. This would make the component more maintainable and less error-prone.

Copilot · 2025-11-03T08:20:42Z

+        {rows.map((row, rowIdx) => (
+          <Box key={rowIdx}>
+            {columns.map((col, colIdx) => {
+              const value = Object.values(row)[colIdx];


Same issue as Comment 1: accessing row values by index is fragile. The component relies on the order of properties in the row object matching the column order, which is not guaranteed in JavaScript objects.

Copilot · 2025-11-03T08:20:43Z

+        <Text key={rowIdx}>
+          <Text color={borderColor}>{vertical}</Text>
+          {columns.map((col, colIdx) => {
+            const value = Object.values(row)[colIdx];


Same issue as Comments 1 and 2: accessing row values by index is fragile and should use explicit key mapping instead.

Suggested change

const value = Object.values(row)[colIdx];

const value = row[col.header];

Copilot · 2025-11-03T08:20:43Z

+  const maxCount = Math.max(...Object.values(statusCounts));
+  const barWidth = 40;
+  const createBar = (count: number, color: string) => {
+    const width = Math.round((count / maxCount) * barWidth);


Division by zero will occur when maxCount is 0 (e.g., when there are no specs). This will result in NaN which could cause rendering issues. Add a guard condition to handle the case when maxCount === 0.

Suggested change

const width = Math.round((count / maxCount) * barWidth);

const width = maxCount === 0 ? 0 : Math.round((count / maxCount) * barWidth);

 const STATUS_CONFIG: Record<SpecStatus, { emoji: string; label: string; color: string }> = {
-  planned: { emoji: '📅', label: 'Planned', color: 'gray' },
+  planned: { emoji: '📅', label: 'Planned', color: 'cyan' },


The STATUS_CONFIG object is duplicated between Board.tsx and StatusBadge.tsx with slightly different color values (here 'cyan', in StatusBadge.tsx also 'cyan', but previously was 'gray' in the old line). Consider importing and reusing the configuration from StatusBadge.tsx to maintain a single source of truth for status styling.

+};
+
+export const getPriorityEmoji = (priority: SpecPriority): string => {
+  return PRIORITY_CONFIG[priority]?.emoji || '';


Inconsistent fallback values: getStatusEmoji returns '❓' when status is not found, but getPriorityEmoji returns an empty string. Consider using a consistent fallback approach (e.g., both return '❓' or both return empty string) for better user experience.

Suggested change

return PRIORITY_CONFIG[priority]?.emoji || '';

return PRIORITY_CONFIG[priority]?.emoji || '❓';

-  console.log(chalk.green('=== Specs ==='));
-  console.log('');
+  // Build filter info for component
+  const filterInfo: any = {};


Using any type defeats the purpose of TypeScript's type safety. Define a proper interface for filterInfo or use a more specific type that matches the expected structure for the SpecListView filter prop.

Suggested change

const filterInfo: any = {};

interface SpecListViewFilterInfo {

status?: string;

tags?: string[];

priority?: string;

assignee?: string;

}

const filterInfo: SpecListViewFilterInfo = {};

…293) Pulls the latest plan-dag (upstream commits #9–#13): renderer collapsed to PNG-only, status fills + available-next highlight, duplicate-id labels rejected, and the obsolete ascii/tb/svg/html fixture artifacts dropped. Moves the skill from .claude/skills/plan-dag/ (real directory) to .agents/skills/plan-dag/ with a .claude/skills/plan-dag symlink, matching the multi-agent layout the skills CLI now emits.
