lathe

Run the Lathe worker loop so the web UI's Ask / Verify / Add-a-part buttons drive work directly in this session instead of handing back a command to paste. Use when the user invokes /lathe-work (start it once per session while `lathe serve` is running). Works in any coding agent.

Generate hands-on technical tutorials for any topic on demand. Use when the user invokes /lathe with a topic like "/lathe build a digital synth in Zig" or "/lathe how to build a compiler in Rust".

Write the next part of an existing Lathe tutorial, in session. Use when the user invokes /lathe-extend with a slug like "/lathe-extend digital-synth-zig" (the "Add a new part" button in `lathe serve` hands you that command), optionally followed by guidance for where the part should go.

Author a custom writing voice for Lathe tutorials, in session, then persist it via the CLI. Use when the user invokes /lathe-voice (optionally with a name like "/lathe-voice terse") to craft a new tone/register preset that /lathe can generate in.

Answer a reader's question about a specific part of a Lathe tutorial, in session. Use when the user invokes /lathe-ask with a slug and part like "/lathe-ask digital-synth-zig part-02.md" followed by the question on the next line (the "Ask" button in `lathe serve` pastes exactly this).

Pick or backfill the search tags on a stored Lathe tutorial, in session. Use when the user invokes /lathe-tag with a slug like "/lathe-tag digital-synth-zig" to choose good tags for the `lathe serve` search and tag filters, or to backfill tags on a tutorial that has none.

Verify that a stored Lathe tutorial actually works by following it end to end in a fresh scratch dir, in session. Use when the user invokes /lathe-verify with a slug like "/lathe-verify digital-synth-zig" (the "Verify this tutorial" button in `lathe serve` hands you that command).
