Lathe Tag

Lathe — Tag a Tutorial

Choose the tags that make a stored tutorial findable in lathe serve's search and tag filters. Triggered by /lathe-tag <slug>.

Protocol

1. Read the tutorial at ~/.lathe/tutorials/<slug>/ to understand what it actually teaches.

2. Pick 2–5 lowercase, reusable tags. Same vocabulary guidance as the lathe skill's tag step: cover, where they apply —

   • the language/runtime — zig, rust, go;
   • the domain — audio, compilers, databases;
   • the core technique — parsing, dsp, concurrency.

   Prefer short, reusable tags that will group naturally with other tutorials over hyper-specific one-offs. Don't pre-lowercase or de-dupe defensively — store.NormalizeTags is the one place that canonicalizes (trim, lowercase, de-dupe), so just pass sensible tags and let it normalize.

3. Persist them. To set the whole tag list (the usual case — choosing or replacing tags):

   lathe tag <slug> --set zig --set audio --set dsp
   

   For incremental edits to an existing set, use --add / --remove instead:

   lathe tag <slug> --add embedded
   lathe tag <slug> --remove misc
   

   --set replaces the entire list; --add/--remove edit it in place. All three are repeatable and accept comma-separated values.

4. Report the resulting tag set to the user (the command prints it).

Boundaries

• Only touches tags, and only via lathe tag. Never edit metadata.json directly.
• No generation, verification, or extension — just tags.
