Your notes are your tasks. Frontmatter in, feed and calendar out, built on Obsidian Bases.

Why

One markdown note is one task. Every field (status, due date, priority, project, recurrence) is an ordinary frontmatter property, not a hidden database or a bespoke query language. The feed and calendar are just Bases views, so Bases' own filters, sorting, and properties toolbar work on them exactly like they work on any other view you build. There is nothing to migrate to and nothing to migrate away from: the notes are still just notes.

Features

• Feed buckets tasks into Overdue, Today, This week, Next week, Later, and No date. See feed buckets.
• Calendar month, week, and day views. Drag or resize an event to reschedule, click an empty slot to create a task, undo or redo a reschedule from the command palette.
• Recurrence is RRULE-based; completing an occurrence spawns the next one as a new note. See recurrence semantics.
• Statuses are two kinds, open and done, toggled from the feed's status circle, the file menu, or the task panel.
• Priorities are normal, high, or urgent.
• Projects are a wikilink to a project note; that note's color property colours the task in the feed and on the calendar.
• Task panel is a sidebar form for the active note, with a command for every field.
• Mobile ready: no desktop-only APIs, long-press to drag events on the calendar, haptic feedback on iOS (toggle in settings).
• Your property names every frontmatter key is renameable in settings, not just the ones shown above.
• Commands for everything above, plus convert note to task, create/open the tasks base, and undo/redo a reschedule, all in the command palette.

Settings

• Task folder, tasks base path: where new task notes and the generated .base file live.
• New task filename template, spawn filename template: filename for a new or spawned task note, supporting {{title}} and (spawn only) {{due}}.
• Week starts on: which day the feed's this week / next week buckets split on.
• Property keys: every frontmatter key above, plus the marker key/value that identifies a note as a task, individually renameable.

Using isotask with AI agents

Point an agent that writes notes into your vault at docs/AGENT-GUIDE.md — it covers the frontmatter schema and recipes an agent needs, with no plugin source access required. For the vault's actual property keys, statuses, and task folder, run app.plugins.plugins.isotask.api.agentInstructions() (Obsidian CLI eval) or the Copy agent instructions command, and hand the agent the result.

What the plugin reads

Isotask never reads note bodies and never sends anything off-device. It lists vault files only where a picker needs them: the project note picker (markdown notes), the tag picker (tags from the metadata cache) and the folder picker (folder paths). Task data is read from the metadata cache of the notes your Bases views already select. It also writes completed (and spawns a recurrence occurrence) whenever a task note's status changes while Obsidian is running, whichever surface changed it — the plugin's own controls, the Properties view, or anything else that edits frontmatter.

Manual

Download main.js, manifest.json, and styles.css from the latest release into <vault>/.obsidian/plugins/isotask/, then reload Obsidian and enable Isotask in Settings.

Isotask requires Obsidian 1.13.0 or later (Bases).

To update, repeat the manual steps above with the new release's files.

Quick start

1. Run the Create tasks base command. It creates Tasks.base with a feed and a calendar view.
2. Run Create task to add a task note.
3. Set a due date, from the task panel or the Set due date… command.
4. Open Tasks.base and switch between the feed and calendar views from Bases' view switcher.
5. Complete it: click the status circle on its feed row.

A task note's frontmatter, with the default property keys:

Development

pnpm install
pnpm dev         # esbuild watch build
pnpm check       # typecheck + lint + test + build
pnpm test        # vitest run
pnpm test:e2e    # full e2e suite (builds first)
pnpm wt feat/<name> # new worktree branched off main, deps installed

For a fast e2e debug loop, filter to one spec and one test name: E2E_GREP="<pattern>" pnpm test:e2e --spec <substring>.
