Content calendar with Linear as source of truth + custom UI

A custom calendar UI built on top of Linear as the source of truth (tasks, dates, platform tags, assignees) and Obsidian as the body store (post drafts, style notes). Live Instagram-analytics layer overlays per-post performance. Built in 3 days by a non-engineer team member at a startup using vibe-coding.

Linear's flat list is hostile to a content team that thinks in calendar grids. A thin custom UI over the same data restores the workflow without locking the team into another SaaS. Per-post analytics show up where decisions are made, not in a separate tab.

1. Make Linear the single source of truth: content tasks have title, due date, platform tag, assignee.
2. Each Linear task references a post body file in Obsidian (e.g., Content/{date}-{slug}.md).
3. Vibe-code a custom calendar UI that reads Linear via MCP / API and Obsidian content notes.
4. Pull Instagram (or other channel) analytics nightly into a small local store; overlay on past-date cells.
5. Wire a content-calendar skill that can update posts / dates by voice ("move next Tuesday's post to Friday").
6. Agent auto-generates draft cards from daily-sync output so the calendar fills itself.

• The skill must hit Linear directly, not a Linear plugin inside Obsidian. The "trusted source" has to be the same record everywhere — duplicate state will diverge within a week.
