Shopping Lists

Track per-store shopping lists so the user can recall what they wanted when they're at that store. Use second-brain for shared vault conventions.

Tools

One file per store, at Shopping/[Store Name].md. The server derives the path from the store name.

A store list is deliberately a flat list of checkboxes with no sections — obsidian__checklist_set needs a section argument only for notes that have sections, so keeping the file sectionless is what makes every later add a one-argument call.

obsidian__checklist_set adds the item if it is missing, merges new detail into the line if it is already there, and checks or unchecks it. It never removes a line, so a repeat capture is always safe.

Workflow

Adding an item ("add X to the Home Depot list", "I need to grab X next time I'm at Costco"):

1. obsidian__checklist_set note="Home Depot" item="Wood screws" detail="2 inch". Preserve the user's wording in item.
2. If the store has no list yet, obsidian__note_create type="shopping" name="Home Depot" first, then add the item.
3. Merging is automatic: a repeat capture of the same item folds new detail into the existing line rather than adding a second one.
4. If the item relates to a project, include the [[Project Name]] wikilink in the item text.

Checking a list ("what do I need at Home Depot?"):

• obsidian__vault_read note="Home Depot" and report the unchecked items.

Marking bought:

• obsidian__checklist_set note="Home Depot" item="Wood screws" checked=true. A checked item stays on the list as the record that it was bought; nothing removes it.

No store specified:

• If the item clearly maps to a store the user already has a list for, use that list.
• Otherwise ask, or put it in Inbox.md if it's ambiguous between a shopping item and a task.

Boundaries

• Errands with deadlines ("buy X before Friday") also get a task in Tasks.md via task-tracking, linking the store list if useful.
• Trip/event expense tracking is out of scope here; capture to Inbox.md if the user asks for it.
• Recurring staples: keep them in a separate note, e.g. obsidian__note_create type="shopping" name="Costco Staples", and copy items across on request. Do not add a ## Staples heading to a store list — a store file with any section makes section required on every later obsidian__checklist_set, and a one-off purchase then gets filed into the staples list by mistake.
