TODO Update Skill

Interactively toggle TODO item completion status in daily notes.

When to Use

• User says "update todo", "complete todo", "todo done", "reopen todo", etc.
• Invoked as /todo-update

Workflow

Step 1: Locate Vault

VAULT_DIR="$HOME/repo/github.com/Takayyz/obsidian-vaults/vaults"

Step 2: Determine Date Range

Parse arguments to determine which daily notes to scan:

Argument	Behavior
(none)	Last 7 days
--today	Today only
--days=N	Last N days

Calculate the date range and glob matching files in $VAULT_DIR/daily/.

Step 3: Collect TODO Items

For each daily note in the date range (newest first):

1. Read the file
2. Extract lines between ## TODO and the next ## heading
3. Parse each line as either:
   • - [ ] content (incomplete)
   • - [x] content (complete)
4. Record the date (from filename), line number, and completion status for each item

Skip files that don't exist or have no ## TODO section.

Step 4: Present TODO Items

If index numbers are provided as arguments (e.g., /todo-update 1,3), use the same ordering as /todo-list (newest date first, then file order within each date) to resolve the indices. Skip directly to Step 5 with the matched items.

Otherwise, collect and display items interactively.

By default, show only incomplete items as a numbered list:

Select TODO(s) to update:
  1. [ ] [2026-01-03] Buy groceries
  2. [ ] [2026-01-03] Write meeting notes
  3. [ ] [2026-01-02] Review PR #42
Enter number(s) (comma-separated, or "all" to include completed):

• Default: show only incomplete (- [ ]) items
• If user enters "all", re-display including completed (- [x]) items with their status shown
• If no updatable items exist, display "No TODO items found in the specified range." and stop

When showing all items, indicate current status:

Select TODO(s) to update:
  1. [ ] [2026-01-03] Buy groceries
  2. [ ] [2026-01-03] Write meeting notes
  3. [x] [2026-01-02] Send invoice
  4. [x] [2026-01-02] Fix login bug
Enter number(s) (comma-separated):

Index ordering rule: Items are always ordered by newest date first, then by file appearance order within each date. This matches the /todo-list output so indices are interchangeable.

Step 5: Select Action

Present action options:

Action:
  1. Complete ([ ] -> [x])
  2. Reopen  ([x] -> [ ])
Enter number:

• If all selected items are incomplete, default to "Complete"
• If all selected items are complete, default to "Reopen"
• If mixed, always ask

Step 6: Update Daily Note

For each selected item, edit the daily note file:

• Complete: Change - [ ] to - [x] on the target line
• Reopen: Change - [x] to - [ ] on the target line

Use the Edit tool. Only modify the checkbox portion of the line. Do NOT change any other content.

Step 7: Carry Forward Incomplete Items (Optional)

If the updated item is from a past date (not today) and the action was Reopen, ask:

This item is from a past date. Carry forward to today's note? (y/n):

• If yes, append the item as - [ ] content to today's ## TODO section
• In the original date's note, mark the carried-forward item as completed with a forward reference: - [x] content (→M/DD) where M/DD is today's date (e.g., (→3/16))
• If today's daily note doesn't exist, create it from the template ($VAULT_DIR/_templates/daily-template.md, replacing {{date}})

Step 8: Confirm

Display a summary of the changes:

Updated:
  [2026-01-03] Buy groceries: [ ] -> [x]
  [2026-01-03] Write meeting notes: [ ] -> [x]

If items were carried forward:

Carried forward to 2026-01-03:
  - [ ] Review PR #42

Rules

• Do NOT allow toggling to the same state (e.g., completing an already completed item).
• Only modify the checkbox marker (- [ ] / - [x]). Never change the content text.
• Use the Edit tool for all file modifications. Never overwrite the entire file.
• If ## TODO section is missing in a daily note, skip it silently.
• Preserve the original text of each TODO item exactly as written.
