lathe is a Go CLI plus bundled LLM skills that generate multi-part, hands-on technical tutorials for self-directed learning. You prompt an agent session with /lathe (for example /lathe build a 3D slicer in Erlang); the skill writes Markdown parts and metadata, then lathe serve renders them in a purpose-built local browser UI at http://localhost:4242.The CLI never calls an LLM itself. It stores tutorials under ~/.lathe/tutorials/ (one directory per slug with metadata.json and part-NN.md files), serves them, and exposes deterministic commands the skills invoke (store, verify-result, extend-start, voice add, and similar). Companion skills /lathe-extend, /lathe-verify, /lathe-ask, and /lathe-voice extend, validate, question, or author custom tutorial voices.lathe skills install copies bundled SKILL.md files into Claude Code, Cursor, or Codex so slash commands are discoverable. Voices (plainspoken, companion, or custom) control prose style; each tutorial records its voice and source model in metadata and in an authorship byline.

--port N

HTTP port for serve (default 4242).

Install skills to ~/.claude/skills/ (Claude Code) or ~/.agents/skills/ (Codex) instead of the current directory.

Skill install target: cursor (writes .cursor/commands/), codex, or all.

Tutorial storage: ~/.lathe/tutorials/<slug>/ with metadata.json (title, topic, tags, tools, sources, voice, model, status). Custom voices are saved under ~/.lathe/voices/ via lathe voice add. Default HTTP port is 4242; override with --port on serve.

Tutorial generation quality depends on the frontier model used in your agent session. Skills are tuned for Claude Code on macOS; Linux installs use the install.sh script or go install. The Homebrew cask is macOS-only.
