Environment Requirements

This plugin requires two runtimes:

Python 3.12+ with uv for:

•Instagram scraping (ScrapeCreators API)
•Event deduplication (rapidfuzz)
•Newsletter generation (Jinja2)
•Config validation (Pydantic)

Node.js 18+ with bun for:

•Facebook event scraping (facebook-event-scraper npm)

Why Two Runtimes?

The facebook-event-scraper library is JavaScript-only with no Python equivalent. Rather than reimplement it, we use a subprocess bridge with strict JSON contracts.

Package Managers

•uv: Fast Python package manager with lockfile support
•bun: Fast JavaScript runtime and package manager

Both ensure reproducible environments via lockfiles (uv.lock, bun.lockb). </essential_principles>

<intake> What do you need help with?

•Full setup - Install all dependencies from scratch
•Check environment - Verify everything is configured correctly
•Update dependencies - Update to latest compatible versions
•Troubleshoot - Debug environment issues

Wait for response before proceeding. </intake>

<routing> | Response | Workflow | |----------|----------| | 1, "setup", "install", "fresh" | `workflows/setup-environment.md` | | 2, "check", "verify", "status" | Run verification checks inline | | 3, "update", "upgrade" | Run `uv sync --upgrade` and `bun update` | | 4, "troubleshoot", "debug", "help" | Diagnose common issues | </routing>

<success_criteria> Environment is ready when:

• uv --version returns 0.4.0+
• bun --version returns 1.0.0+
• uv run python -c "import rapidfuzz" succeeds
• bun run scripts/scrape_facebook.js --help succeeds
• .env file exists with SCRAPECREATORS_API_KEY set
• config/sources.yaml exists and validates </success_criteria>
