TaskNotes Skill

This skill works with tasks managed by the TaskNotes plugin. Each task is a Markdown file with YAML frontmatter stored in a configurable folder (default: TaskNotes/Tasks/).

Operate on task mutations through the plugin's API, not by hand-editing frontmatter. When this skill is enabled and the integration is approved you have an exec_tasknotes tool that runs JavaScript against the TaskNotes api object (in scope as api) on the main thread. The API is the correct interface for create/update/complete: it manages ids, dates, recurrence, and completion for you, and validates input.

• api is the TaskNotes plugin API (apiVersion === 1); app is the Obsidian app.
• Tasks are addressed by their file path.
• Init happens at layout-ready. If a call fails early, guard with if (!api.lifecycle.isReady()) await api.lifecycle.ready() first.
• Not sandboxed, and this includes reads. api runs on the main thread with full app access, the same as raw app.vault calls — api.getTask, api.listTasks, and api.query.tasks read task file content directly and do not respect the user's per-provider privacy rules the way search_notes / read_content / grep_notes do. Awaited work times out. Keep snippets read-only unless the user asked to modify data.
• If unsure of the surface at runtime, introspect: return Object.keys(api) or return api.capabilities.

Reading & Querying

Prefer search_notes / grep_notes / read_content to find and read individual tasks — they respect the user's privacy rules for restricted notes, api reads do not. Reach for api.getTask / api.listTasks only when you specifically need TaskNotes' parsed, typed fields (status/priority/recurrence resolved from frontmatter) rather than raw content:

// One task by path
return await api.getTask("TaskNotes/Tasks/Buy groceries.md");

// Flat list (optionally filtered) — returns TaskInfo[]
return await api.listTasks();

For structured queries with predicates, sorting, grouping, and pagination across many tasks — something search_notes/grep_notes can't express — use api.query.tasks(query). This is the one case where api is worth its privacy trade-off: filtering/aggregating by status, priority, or due date across the whole task folder in one call. Mention to the user that results may include tasks they've marked private if they ask, since this path doesn't filter them:

// Open tasks due within a week, soonest first
return await api.query.tasks({
  where: { all: [
    { field: "status", op: "ne", value: "done" },
    { field: "due", op: "exists" },
  ]},
  sort: [{ field: "due", direction: "asc" }],
  limit: 20,
});

Predicate nodes are { all: [...] } / { any: [...] } / { not: ... } or a leaf { field, op, value }. Operators: eq, ne, contains, notContains, in, notIn, exists, missing, lt, lte, gt, gte, isTrue, isFalse. api.query.validate(query) checks a query before running it; api.stats.tasks(query) returns aggregate counts. Use api.catalog.statuses() / api.catalog.priorities() to discover the user's actual configured values before filtering on them.

To display a live, auto-updating view to the user instead of computing, write a ```dataview fence in your reply (renders natively when Dataview is installed):

TABLE title, status, due, priority
FROM "TaskNotes/Tasks"
WHERE status != "done"
SORT due ASC
LIMIT 20

Creating a Task

return await api.tasks.create({
  title: "Buy groceries",   // required
  status: "open",
  priority: "normal",
  scheduled: "2025-01-15",  // YYYY-MM-DD (or ...THH:MM:SS)
  contexts: ["@errands"],
  projects: ["[[Website Redesign]]"],
  tags: ["shopping"],
  timeEstimate: 30,          // minutes
  details: "Optional body markdown",
});

Only pass fields the user specified. The plugin sets id, date_created, date_modified, and the file path/name — do not supply them. You can also parse natural language first: api.parseNaturalLanguage("buy milk tomorrow high priority") returns structured task data you can hand to create.

Updating & Rescheduling

// General patch
return await api.tasks.update(path, { priority: "high", due: "2025-01-20" });

// Field helpers (clearer intent, same effect)
await api.tasks.setPriority(path, "high");
await api.tasks.setDue(path, "2025-01-20");      // api.tasks.clearDue(path) to remove
await api.tasks.setScheduled(path, "2025-01-17"); // reschedule the planned start
await api.tasks.reschedule(path, "2025-01-17");
await api.tasks.addProject(path, "[[Q1 Launch]]");
await api.tasks.addTag(path, "urgent");

Completing a Task

return await api.completeTask(path);        // or api.tasks.complete(path)
// api.tasks.uncomplete(path) to reopen; api.tasks.setStatus(path, "in-progress") for other states.

The plugin sets the completed date and handles recurrence roll-over automatically — never set a completed date yourself.

Recurring Tasks

Recurrence is RFC 5545 RRULE in the task's recurrence field; scheduled holds the next concrete occurrence (the plugin advances it — don't). Set it at creation/update via the recurrence field:

Pattern	RRULE
Daily	FREQ=DAILY
Every weekday	FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR
Every Monday	FREQ=WEEKLY;BYDAY=MO
Every Mon/Wed/Fri	FREQ=WEEKLY;BYDAY=MO,WE,FR
Bi-weekly	FREQ=WEEKLY;INTERVAL=2;BYDAY=MO
Monthly on the 1st	FREQ=MONTHLY;BYMONTHDAY=1

To toggle a single occurrence complete/skipped, use api.recurring.toggleCompleteInstance(path, date) / api.recurring.toggleSkippedInstance(path, date) rather than editing complete_instances by hand.

Time Tracking

• api.time.start(path) / api.time.stop(path) — start/stop a work session.
• api.time.active() — currently running entries; api.time.summary(path) — tracked-time summary.
• timeEstimate is minutes (integer). Read a task's timeEntries ({startTime, endTime, description}, ISO 8601 UTC) to report tracked time.

Dependencies

Use api.relationships to read task relationships (parents, subtasks, dependencies, blocking, all, each taking a path) and api.tasks.addDependency(path, ...) / removeDependency(path, ...) to change them. Relationship types: FINISHTOSTART (most common), FINISHTOFINISH, STARTTOSTART, STARTTOFINISH.

Reference: Task Frontmatter

The api reads/writes these; this is for understanding a task file's shape, not for hand-editing.

Field	Meaning
title	Task title (required)
status	See Statuses below
priority	See Priorities below
due	Hard deadline — "due by", "deadline" (YYYY-MM-DD[THH:MM:SS])
scheduled	Planned start — "work on it on", "plan for"; holds the next occurrence for recurring tasks
contexts	List of @context strings
projects	List of [[wikilinks]] or plain strings
tags	Native Obsidian tags
timeEstimate	Minutes (integer)
recurrence / recurrence_anchor	RRULE; anchor is "scheduled" or "completion"
reminders	`{type: "relative"
archived	Boolean
id, date_created, date_modified, completed_date	Plugin-managed — never set these

due and scheduled are independent: a task can have either, both, or neither.

Statuses (defaults — user may customize; read api.catalog.statuses() to confirm)

Status	Meaning	Completed?
open	Not yet started	No
in-progress	Actively being worked on	No
done	Completed	Yes

Priorities (defaults — read api.catalog.priorities() to confirm)

none, low, normal, high.

Tips & Constraints

• Prefer search_notes/read_content/grep_notes to find and read individual tasks — they respect the user's privacy rules; api reads do not. Prefer the api for mutations (create/update/complete) and for cross-task queries/aggregation search_notes can't express — it validates input and manages plugin-owned fields. If the exec_tasknotes tool is not available (integration off), do everything through search_notes/read_content/manage_notes and say so.
• Read the user's configured statuses/priorities via api.catalog.* before filtering on values that may have been customized.
• Task folder path is configurable; the api resolves paths for you, so you rarely need to know it.
• Tasks vs TaskNotes: if each task is its own file with YAML frontmatter, this is the right skill; if the user's tasks are - [ ] checkbox lines inside notes, use the tasks skill instead.

Working with the Bases Skill

If the bases skill is enabled, you can create .base views over the task folder for a rich UI. Example — open tasks by priority:

filters:
  and:
    - file.inFolder("TaskNotes/Tasks")
    - 'status != "done"'

formulas:
  days_until_due: 'if(due, (date(due) - today()).days, "")'

views:
  - type: table
    name: "Open Tasks"
    order:
      - file.name
      - status
      - priority
      - due
      - formula.days_until_due
    groupBy:
      property: priority
      direction: DESC
