Tag Descriptions are short editorial blurbs you attach to any hashtag — the metadata layer of 📝Tagging that explains what a collection is actually about. A raw tag is just a word; a description turns it into a defined term: context for a visitor landing on the tag page, a meta description for search engines, and a definition for the AI agents reading your MythOS library. They're for creators who want their tags to read as a curated index, not a pile of keywords.
Key Capabilities
- Per-tag descriptions — write a blurb for any tag from tag management or the in-editor tag popover
- AI generation — auto-draft a description from the memos carrying the tag, then edit to taste
- Bulk generation — generate descriptions for many tags at once from a single action
- Tag-page overview — the description renders atop the public tag page, above the memo list
- Search + answer-engine surface — it fills the tag page's meta description, structured data, and
llm.txt - Pairs with metadata — sits alongside a tag's type and its linked explainer memo

FAQ
- Where do descriptions show up? On the public tag page as overview text and meta description, in the page's structured data, and in the per-tag
llm.txtthat agents read. - How long can a description be? The tag-management editor and AI generator cap it at 120 characters; the agent API and MCP
update_tagtool allow up to 200. - Can AI write them for me? Yes — "Suggest with AI" drafts from up to ten memos carrying the tag, and a bulk action covers many tags at once.
- Do descriptions change what's in a tag's collection? No. They're editorial context only; the collection is still every memo carrying the tag.
- Can an agent set a description? Yes — the
update_tagMCP tool and the internal tags API both write tag descriptions.
