• Generates starter code with TODOs
• Includes test cases + hints
• Difficulty levels (Easy/Medium/Hard)

2. Project Templates

• Complete scaffolding (Rust, C++, TypeScript)
• Build configs (Cargo.toml, CMakeLists.txt, package.json)
• README with setup instructions
• Success criteria

3. AI Challenges (100 Days of Building with AI)

• Daily project ideas (60-90 min)
• Cycles through AI tools (Cursor, Copilot, Claude, v0, Perplexity)
• Specific deliverables
• Progress tracking

4. Reflection Prompts

• For philosophy/self-help content
• Open-ended questions
• Connects to personal experience

Test: pnpm generate:test

---

✅ Phase 4: API & Scheduling (COMPLETE)

REST API (Fastify)

pnpm api:dev  # Start API server

Endpoints:

• GET /api/articles - Get curated articles
• POST /api/articles/refresh - Trigger scrape
• GET /api/exercises - Get exercises
• GET /api/challenges/today - Get today's AI challenge
• GET /api/challenges/progress - Track 100 Days progress

Automated Scheduler (node-cron)

pnpm scheduler:dev  # Start scheduler

Cron Jobs:

• 6 AM UTC: Daily scrape + curation + generation
• 7 AM UTC: Daily AI challenge generation

Manual Triggers:

• pnpm trigger:scrape - Run daily pipeline now
• pnpm trigger:challenge - Generate today's challenge

---

✅ Phase 5: Integrations (COMPLETE)

Notion Sync

• Syncs curated articles to Daily Digest database
• Syncs AI challenges to 100 Days database
• Rich content blocks (summaries, checklists)
• Auto-tagged and categorized

GitHub Automation

• Daily commits to 100-days-of-ai repo
• Creates challenge folders with README
• Updates main README with progress bar
• Tracks streak and completion percentage

Example Progress Bar:

Day 42/100 (42% Complete)

🚀 Quick Start

1. Install Dependencies

pnpm install

2. Configure Environment

cp .env.example .env
# Edit .env with your API keys

Required:

• ANTHROPIC_API_KEY - Claude API key

Optional (for integrations):

• NOTION_API_KEY - Notion integration token
• NOTION_DAILY_DIGEST_DB - Database ID for articles
• NOTION_AI_CHALLENGE_DB - Database ID for challenges
• GITHUB_TOKEN - Personal access token
• GITHUB_REPO - Repository (e.g., username/100-days-of-ai)

3. Test Individual Phases

pnpm scrape:test      # Test scraper
pnpm curate:test      # Test curator
pnpm generate:test    # Test generator

4. Run the System

# Start API server
pnpm api:dev

# Start scheduler (in another terminal)
pnpm scheduler:dev

# Or trigger manually
pnpm trigger:scrape
pnpm trigger:challenge
