Task Tracking

Manage centralized tasks in the user's Obsidian second brain. Use second-brain for shared vault conventions and project-tracking when project state must be created or changed.

Tools

Tasks.md has a positional grammar, so it is owned by two tools and nothing else can write to it — obsidian__section_append on Tasks is refused with an error saying so.

Use obsidian__task_query for any status lookup — overdue, due soon, waiting, completed since a date — instead of reading Tasks.md and parsing it by eye; reach for obsidian__vault_read only when you need the note's exact wording or full layout.

obsidian__task_add composes the line, files it in the right section, and rejects a near-duplicate of an existing task. obsidian__task_update finds the task by a distinctive fragment of its text, recomposes the whole line, and moves it between sections — including any sub-items nested under it.

Pass the parts as arguments; never assemble a task line yourself. text is the user's wording only: a leading - [ ], a 📅 date, or a ⏫ priority inside text is refused, because those belong in the due and priority arguments where the tools can read them.

Adding a Task

obsidian__task_add text="Send the revised proposal" project="Wayfinder" due="2026-08-04" priority="high"

• project must be the exact name of an existing project note. A project with no note is refused rather than written as a dangling link; the error lists the projects that do exist.
• section defaults to Active, or to Waiting On Others when waiting_on is set. Use Waiting On Me when the user owes someone something.
• waiting_on takes a person's note name and files the task under Waiting On Others with a dated marker. waiting_since defaults to today.
• notes is a short trailing note for anything that does not fit the other fields — including a date the user was vague about. Never invent a date to fill due.

If the task covers work an open task already covers, obsidian__task_add refuses and names the existing task. Update that one instead of adding a second line.

Then, when the task belongs to an existing project, record it on the project note:

obsidian__section_append note="Wayfinder" section="Related Tasks" content="- Send the revised proposal"

Updating a Task

obsidian__task_update match="revised proposal" due="2026-08-06" priority="medium"

• match is a distinctive fragment of the existing task text and must identify exactly one task. If it matches several, the error lists them; pass a longer fragment.
• done=true checks the box, stamps the completion date, and moves the task to ## Done. done=false reopens it.
• section moves the task explicitly. Sub-items indented under a task move with it.
• An empty string clears project, due, waiting_on, or notes. priority="none" clears the priority.
• Rewording a task into an existing task's wording is refused, for the same reason a duplicate add is.

Task-Project Relationship

• Tasks.md is the source of task state. Projects/[Project Name]/[Project Name].md is the source of project state.
• When a task belongs to a project, keep a concise reference under that project's ## Related Tasks.
• Do not duplicate project status in task notes unless it is necessary context.
• Do not create a project because a task mentions a possible project name, unless the user clearly wants it tracked as one.
• Do not mark a project Done, Blocked, or On Hold because a task changed. Route explicit project state changes to project-tracking.
• If task state and project state conflict, preserve both and surface the inconsistency rather than reconciling it yourself.

Due Dates and Waiting States

• Resolve relative dates ("friday", "end of month") with obsidian__date_resolve before calling; pass its date. The tools take exact YYYY-MM-DD and refuse anything else, including impossible dates like 2026-02-31.
• Tasks needing the user's action go in Active, or Waiting On Me when the user owes it to someone specific.
• Tasks blocked by someone else go in Waiting On Others via waiting_on.
• Preserve an unclear date in notes rather than inventing one.

For example, from a vault_status today of 2026-08-01:

obsidian__date_resolve expression="next friday"
obsidian__task_add text="Send the revised proposal" project="Wayfinder" due="2026-08-07"

Nudging Logic

Use this when asked to review, or when another skill needs task signals:

• Overdue — due date before today and the task is not done.
• Due soon — due in the next 3-5 days.
• Idle — an active task with no visible update for more than 7 days, judged only from dated evidence (due dates, since dates, completion dates, dated notes). Skip idle detection for items with no dates; do not guess.
• Waiting on others — waiting more than 5 days per the since date.

Do not nudge the same item twice in less than 48 hours when prior nudge data is available.

Safety

• Nothing in the tool surface deletes a task, and completion is a move to ## Done, not a removal.
• Do not infer completion from conversational optimism; require explicit completion language.
• Ask, or capture to Inbox.md, when a task has multiple plausible projects or owners.
