- POST /api/me/avatar/url stores the https link (users.avatar_link) instead
of downloading it; GET /api/me/avatar and /api/users/:id/avatar answer 302
to it (no referrer). Link rules: https, no userinfo, <= 2048 chars, no
localhost or private/reserved IP literal. Upload and link replace each other.
- Settings -> Account first loads the link as an embedded image and refuses
one this browser cannot show: a picture behind a login (Mattermost's
/api/v4/users/<id>/image) gets no cookie cross-site and 401s.
- Files sidebar: each workspace under its owner's home, chevrons remembered
per browser (agenthub.files.homesOpen); ownerless ones stay flat.
- Artifacts hub: upload a file from the computer; make a skill by uploading a
Markdown file, files, a folder or a .zip/.skill, or by writing it in the
dialog; add plugins by picking from the list a marketplace link answers
(POST /api/artifacts/plugin/inspect); Settings → AI tools → Artifacts Hub.
- Console tabs are combos of up to four split panes (ConsoleTabs, PaneGrid).
- Accounts: an own avatar (PUT/DELETE /api/me/avatar, raster only, ≤ 1 MB,
<data dir>/avatars/), shown with name and role at the sidebar's foot and on
the workspace owner groups (GET /api/users/:id/avatar, owner_avatar_at).
- Users page: per-user storage (GET /api/users/storage, measured in a worker)
and account-pool spend/tokens per account (server/lib/pool-usage.js).
