catlog22 7e70e4c299 perf(ccw): optimize I/O operations and add caching layer
Performance Optimizations:

1. Async I/O Operations (data-aggregator.ts, session-scanner.ts):
   - Replace sync fs operations with fs/promises
   - Parallelize file reads with Promise.all()
   - Add concurrency limiting to prevent overwhelming system
   - Non-blocking event loop during aggregation

2. Data Caching Layer (cache-manager.ts):
   - New CacheManager<T> class for dashboard data caching
   - File timestamp tracking for change detection
   - TTL-based expiration (5 minutes default)
   - Automatic invalidation when files change
   - Cache location: .workflow/.ccw-cache/

3. CLI Executor Optimization (cli-executor.ts):
   - Tool availability caching with 5-minute TTL
   - Avoid repeated process spawning for where/which checks
   - Memory cache for frequently checked tools

Expected Performance Improvements:
- Data aggregation: 10x-50x faster with async I/O
- Cache hits: <5ms vs 200-500ms (40-100x improvement)
- CLI tool checks: <1ms cached vs 200-500ms

CCW - Claude Code Workflow CLI

A command-line tool for viewing workflow sessions and code review results from the Claude Code Workflow system.

Installation

# Install globally
npm install -g ccw

# Or install from local source
cd path/to/ccw
npm install
npm link

Usage

View Dashboard

# Open workflow dashboard in browser
ccw view

# Specify project path
ccw view -p /path/to/project

# Generate dashboard without opening browser
ccw view --no-browser

# Custom output path
ccw view -o report.html

Features

Workflow Dashboard

  • Active Sessions: View all active workflow sessions with task progress
  • Archived Sessions: Browse completed/archived sessions
  • Task Tracking: See individual task status (pending/in_progress/completed)
  • Progress Bars: Visual progress indicators for each session

Review Integration

  • Code Review Findings: View results from review-module-cycle
  • Severity Distribution: Critical/High/Medium/Low finding counts
  • Dimension Analysis: Findings by review dimension (Security, Architecture, Quality, etc.)
  • Tabbed Interface: Switch between Workflow and Reviews tabs

Dashboard Data Sources

The CLI reads data from the .workflow/ directory structure:

.workflow/
├── active/
│   └── WFS-{session-id}/
│       ├── workflow-session.json    # Session metadata
│       ├── .task/
│       │   └── IMPL-*.json          # Task definitions
│       └── .review/
│           ├── review-progress.json # Review progress
│           └── dimensions/
│               └── *.json           # Dimension findings
└── archives/
    └── WFS-{session-id}/            # Archived sessions

Bundled Templates

The CLI includes bundled dashboard templates:

  • workflow-dashboard.html - Workflow session and task visualization
  • review-cycle-dashboard.html - Code review findings display

No external template installation required - templates are included in the npm package.

Requirements

  • Node.js >= 16.0.0
  • npm or yarn

Integration with Claude Code Workflow

This CLI is a standalone tool that works with the Claude Code Workflow system:

  1. Install CCW CLI (via npm)

    • npm install -g ccw
    • Provides ccw view command for dashboard viewing
    • Templates are bundled - no additional installation required
  2. Optional: Install Claude Code Workflow (via Install-Claude.ps1)

    • Provides workflow commands, agents, and automation
    • CCW will automatically detect and display workflow sessions

Options

-p, --path <path> Path to project directory (default: current directory)
--no-browser Generate dashboard without opening browser
-o, --output <file> Custom output path for HTML file
-V, --version Display version number
-h, --help Display help information
