Complete Skill Installation Workflow
One-command installation: fetch → scrape → enhance → package → upload

This CLI tool orchestrates the complete skill installation workflow by calling
the install_skill MCP tool.

Usage:
    skill-seekers install --config react
    skill-seekers install --config configs/custom.json --no-upload
    skill-seekers install --config django --unlimited
    skill-seekers install --config react --dry-run

Examples:
    # Install React skill from official configs
    skill-seekers install --config react

    # Install from local config file
    skill-seekers install --config configs/custom.json

    # Install without uploading
    skill-seekers install --config django --no-upload

    # Preview workflow without executing
    skill-seekers install --config react --dry-run

Examples:

  # Install without uploading

Important:
  - Enhancement is MANDATORY (30-60 sec) for quality (3/10→9/10)
  - Total time: 20-45 minutes (mostly scraping)
  - Multi-platform support: claude (default), gemini, openai, markdown
  - Auto-uploads if API key is set (ANTHROPIC_API_KEY, GOOGLE_API_KEY, or OPENAI_API_KEY)

Phases:
  1. Fetch config (if config name provided)
  2. Scrape documentation
  3. AI Enhancement (MANDATORY - no skip option)
  4. Package for target platform (ZIP or tar.gz)
  5. Upload to target platform (optional)
