Adding a product to a store's shopping list
Vault path: /Users/mtm/Documents/Obsidian Vault
A product is on a store's shopping list when the store's boolean in the product note's front matter is true, for example trader_joes: true.
Each store also has a ## [[Store]] section with a - [x] shopping line further down the note.
Never touch that section checkbox for this task; it is not the shopping list marker.
Step 1 — find the product note
Follow Steps 1 to 3 of the resolve-recipe-ingredient-link skill, using the product as the user phrased it in place of the link text.
For Tier 2, the disambiguators come from the user's own wording (for example "flat leaf" or "dried"), since there is no recipe line.
When several notes match and the user named no variant, prefer the general note that the variants link from, and the one that holds past ✅ dated shopping lines.
Example: "parsley" resolves to parsley.md, not fresh parsley.md, flat leaf parsley.md or dried parsley.md, because parsley.md links to those variants and holds the purchase history.
When the user named a variant, use the variant's note.
Step 2 — create the note when no candidate fits
If no existing note is a plausible match, create one by following Tier 4 of the resolve-recipe-ingredient-link skill.
Name the file after the product as the user said it, all lowercase with spaces between words.
Before writing, check that no note with the same name exists with different capitalization, because a lowercase write onto a capitalized note keeps the old name and git add then does nothing.
Step 3 — set the store key
Match the store the user named to one of the keys already in the note's front matter.
When the user names no store, use amazon_fresh.
Amazon Fresh has closed, so its key serves as the catch-all list for items not yet assigned to a store.
Do not ask which store in that case.
The keys are snake_case forms of the store note names with punctuation dropped, for example trader_joes for Trader Joe's, lam_s_seafood_asian_market for Lam's Seafood Asian Market, and amazon_com for Amazon.com.
Change only that key from false to true, leaving every other line as it is.
If the key is already true, the product is already on the list; report that and change nothing.
If the store matches no key, stop and ask the user, because adding a key would invent a store without a store note to back it.
Step 4 — commit
Background processes commit to the vault too, so commit only the product note by path:
git commit --message "Add <product> to the <store> shopping list" -- "<product>.md"
For a newly created note, run git add "<product>.md" first.
Step 5 — report
Name the note that was changed or created, and the key that was set.
When the store defaulted to amazon_fresh, say that it went on the no-store list.
When a variant note was passed over in favor of the general note, say so in one line, so the user can redirect.
