+description: Manage tasks in Connor's Vikunja instance using the vik CLI tool. Use this skill whenever Connor wants to create, view, update, complete, or delete tasks — including phrasing like "add a task," "what's on my plate," "mark that done," "remove that task," "show me what's due," or any request involving task tracking, to-do items, or his personal task list.

+
+# Vikunja Task Management
+
+Connor manages tasks via a self-hosted Vikunja instance at tasks.connorrhodes.com, accessed through the `vik` CLI tool. Always use `vik` for task operations — never navigate to the web UI or use the API directly.
+
+## Quick Reference
+
+| Goal | Command |
+|------|---------|
+| See today's tasks | `vik task today` |
+| See upcoming tasks | `vik task upcoming [--days N]` |
+| See all tasks | `vik task list` |
+| Find a task | `vik task get <ID or partial title>` |
+| Search tasks | `vik task search <query>` |
+| Create a task | `vik task create "Title" [options]` |
+| Update a task | `vik task update <ID> [options]` |
+| Mark done | `vik task update <ID> --done` |
+| Delete a task | `vik task delete <ID>` |
+
+---
+
+## Creating Tasks
+
+```bash
+vik task create "Task title"
+```
+
+**Options:**
+- `--project ID` — project to add to (default: 1)
+- `--label LABEL` — assign a label (creates it if it doesn't exist)
+- `--desc TEXT` — task description (overrides clipboard)
+- `--no-clip` — skip auto-populating description from clipboard URL
+
+**Date syntax in the title** (parsed automatically, removed from final title):
+- `s+N` — start date N days from now
+- `d+N` — due date N days from now
+
+Examples:
+```bash
+vik task create "Review draft proposal"
+vik task create "Follow up with vendor d+3"
+vik task create "Prep for demo s+1 d+4" --label work
+vik task create "Read article" --no-clip
+```
+
+> Note: if there's a URL in the clipboard, `vik` will automatically embed it as a markdown link in the description unless `--no-clip` is passed.
+
+---
+
+## Reading Tasks
+
+```bash
+vik task today              # tasks with start or due date today
+vik task today --due-only   # only tasks due today (ignores start date)
+
+vik task upcoming           # next 7 days
+vik task upcoming --days 14 # next 14 days
+vik task upcoming --due-only
+
+vik task list               # all tasks
+
+vik task get 42             # fetch task by ID
+vik task get "vendor"       # search by title substring (returns matches)
+
+vik task search "follow up" # full-text search across all fields
+```
+
+When Connor asks "what do I have today" or "what's coming up," run `vik task today` or `vik task upcoming` and present the output.
+
+---
+
+## Updating Tasks
+
+```bash
+vik task update <ID> --title "New title"
+vik task update <ID> --desc "Updated description"
+vik task update <ID> --done
+vik task update <ID> --undone
+```
+
+At least one field is required. `--done` and `--undone` are mutually exclusive.
+
+If Connor says something like "mark that done" or "complete task 7," use `vik task update <ID> --done`.
+
+---
+
+## Deleting Tasks
+
+```bash
+vik task delete <ID>
+```
+
+No confirmation prompt — deletion is immediate. Confirm with Connor before deleting unless he was explicit about it.
+
+---
+
+## Labels
+
+```bash
+vik label list
+vik label create "urgent" --color ff0000
+```
+
+Labels are created automatically when referenced in `vik task create --label`, so you rarely need to create them manually.
+
+---
+
+## Workflow Tips
+
+- If Connor gives a title but no ID, use `vik task get "title"` to find the task first, then act on the result.
+- Task IDs are integers shown in list/today/upcoming output.
+- When creating a task with a URL context (e.g., "add this link as a task"), let clipboard auto-populate work — don't use `--no-clip`.
+- For tasks with relative deadlines ("due Friday," "starts tomorrow"), convert to `d+N` / `s+N` before passing to the CLI.
