knowledge-extraction

hardworker-marketplace

Claude Code plugin marketplace focused on "hardworker" productivity patterns: verification-first development, multi-session collaboration, and evidence-based completion.

TL;DR

• ultrawork - Strict verification-first development. Use for solo features with evidence requirements.
• teamwork - Multi-session collaboration. Use for team projects with parallel workers.
• knowledge-extraction - Capture and extract insights. Use for learning and documentation.

Quick Install:

claude plugin marketplace add mnthe/hardworker-marketplace
claude plugin install ultrawork@hardworker-marketplace

Prerequisites

• Claude Code CLI (latest version with plugin support) - https://claude.ai/download
• Bun 1.3+ (runtime for all plugins) - https://bun.sh/
• Git (version control)
• Platform: Windows, MacOS, or Linux

Quick Start

Installation

# Add marketplace
claude plugin marketplace add mnthe/hardworker-marketplace

# Install verification-first development
claude plugin install ultrawork@hardworker-marketplace

# Install multi-session collaboration
claude plugin install teamwork@hardworker-marketplace

# Install knowledge extraction
claude plugin install knowledge-extraction@hardworker-marketplace

Example: ultrawork Session

# Start verification-first development session
/ultrawork "implement user authentication with JWT"

# System creates plan with tasks and success criteria
# Worker agents execute tasks in parallel
# Verifier checks all criteria with concrete evidence

# Check status
/ultrawork-status

Example: teamwork Session

# Start coordination (orchestrator spawns native teammates automatically)
/teamwork "build REST API with tests and docs"

# Orchestrator creates tasks, spawns role-based workers as native teammates
# Workers execute tasks, coordinate via SendMessage
# Event-driven: TaskCompleted and TeammateIdle hooks drive progress

# Check status
/teamwork-status
