Purpose & behavior

A fully interactive weekly meal planner. A 7-day grid (Monday–Sunday, breakfast/lunch/dinner per day); clicking any slot opens a dialog to set the meal name. A grocery list is auto-generated by matching each planned meal against an ingredient keyword map, deduplicated, with checkboxes that persist; users can also add their own manual items. Stat cards show meals planned, grocery items, and checked-off count. A Clear week button resets everything. All state persists in the browser via localStorage.

Setup

  • Open app.html in any browser — no build step, no dependencies.
  • Tap any meal slot to replace the sample week with your own meals — the grocery list rebuilds itself from the SAMPLE_WEEK data (edit the INGREDIENTS keyword map in the source to teach it your own dishes).

Rebuild instructions

  1. Save the app.html file below exactly as-is (complete, self-contained page, no external dependencies).
  2. Open it in a browser; click a meal slot, type a dish, and save — the grocery list updates automatically.
  3. Check off grocery items, add a manual item, and reload the page to verify everything persists via localStorage.
  4. To make it real: have the agent read the user's calendar for dinner plans or pull recipes from the web, then write the planned meals into the week object in localStorage under the mealPlanner key.
