Dependencies

LLM Wiki has 3 required tools and 5 optional tools. Optional tools lazy-install on first use — you don’t need them upfront.

Optional (auto-install on first use)

Install Script

The included install script checks everything interactively:

./install.sh  # checks deps, installs via Homebrew

Or run /setup inside Claude Code for the same checks with a detailed report.

Zero-Dependency Skills

These skills need nothing beyond curl (always available):

• /ingest (web articles, tweets, gists, text)
• /read-tweet
• /read-gist
• /query, /lint, /promote (filesystem only)
