create-tag

name	create-tag
description	Interactively add one or more new tags to data/works/tags.ts. Checks similarity against existing tags before creating, and keeps the TAGS array alphabetically sorted.
user-triggered	true

Add one or more new tag strings to the TAGS array in data/works/tags.ts.

Input method rules

• Free text (tag names): output the question as plain chat text and wait for the user's reply.
• Choices: use AskUserQuestion.

Step 1 — Read current tags

Read data/works/tags.ts to get the current TAGS array.

Step 2 — Collect new tag names

Repeat until the user is done:

1. Output: "New tag name?" and wait for reply.
2. Similarity check: compare the name (case-insensitively and semantically) against all existing TAGS and tags collected this session. If similar, output a warning:

   ⚠ "<typed name>" looks similar to the existing tag "<similar tag>". Use the existing one instead? Then ask (AskUserQuestion):

   • options: ["Use existing: <similar tag>", "Create new anyway"]
   • header: "create-tag"
3. If no similar tag, or the user chose "Create new anyway", add to the pending list.
4. Ask (AskUserQuestion):
   • question: "Add another tag?"
   • options: ["Yes", "Done"]
   • header: "create-tag"
   • If "Done", stop collecting.

If no names were collected, stop without writing anything.

Step 3 — Write to file

Append each new tag to the TAGS array in data/works/tags.ts, then sort the entire array alphabetically (case-insensitive).

Run bun run typecheck to verify no type errors were introduced.
