Reading additional input from stdin... OpenAI Codex v0.125.0 (research preview) -------- workdir: /home/teodor/little-projects/heapzilla-ai/android/counter-app model: gpt-5.5 provider: openai approval: never sandbox: read-only reasoning effort: medium reasoning summaries: none session id: 019dce9f-829c-7551-bc45-d2fd557b8f58 -------- user You earlier proposed 13 features for 'eventa', a personal event-planning app: 1. **Event Brief** Capture the event’s purpose, date range, location, rough size, budget, and “done means” in one compact planning brief. This keeps the event from turning into a vague pile of tasks with no shared definition of success. 2. **Guest List With RSVP State** Track guests, households, plus-ones, children, RSVP status, dietary needs, and lodging needs. Most planning decisions depend on headcount, and headcount is only useful when it includes real constraints. 3. **Household-Based Invitations** Group people by household so one invite can cover a couple, family, or shared accommodation group. Personal events are rarely individual-ticket affairs, and household grouping avoids messy duplicate communication. 4. **Private Planning Checklist** Generate a lean checklist based on event type, date, guest count, and venue type, then let the user delete aggressively. It solves the “what am I forgetting?” problem without becoming a generic project-management board. 5. **Deadline Timeline** Show upcoming decisions by when they must be made: book venue, confirm food, send invites, buy supplies, finalize headcount. Event stress usually comes from late decisions, not from lack of task storage. 6. **Budget Buckets** Split costs into opinionated buckets like food, drinks, venue, decor, travel, gifts, lodging, and contingency. It makes spending visible early, especially for casual events that quietly become expensive. 7. **Shared Cost Tracker** Track who paid for what, who should reimburse whom, and which costs are personal versus shared. This is essential for trips, group dinners, and family events where money gets awkward if recorded too late. 8. **Menu And Dietary Planner** Plan meals, drinks, portions, dietary restrictions, and grocery quantities from the guest list. Food is often the center of personal events, and this prevents both overbuying and excluding guests. 9. **Packing And Supply Lists** Maintain event-specific lists for things to buy, bring, borrow, rent, and return. This is useful for trips, parties, weddings, and dinners where logistics live outside the venue. 10. **Guest Communication Log** Keep a simple record of what was sent, to whom, and when: save-the-date, invite, reminder, address request, final details. It prevents accidental silence, repeated messages, and missed follow-ups. 11. **Run Of Show** Create a simple event-day schedule with times, owners, locations, and notes. Even casual events benefit from knowing when food arrives, people show up, speeches happen, or cars need to leave. 12. **Decision Ledger** Record important decisions like chosen venue, menu, dress code, gift policy, room assignments, and why they were chosen. This avoids re-litigating decisions and helps when planning with a partner or family. 13. **Post-Event Wrap-Up** After the event, record final costs, notes, vendor feedback, guest count, what worked, and what to repeat next time. Personal event planning gets much easier when each event teaches the next one. 2,801 1. **Event Brief** Capture the event’s purpose, date range, location, rough size, budget, and “done means” in one compact planning brief.

Now critique that list with fresh eyes: 1. What 1-2 features should be CUT or merged because they're over-engineered or duplicate the value of another feature? 2. What 1-2 IMPORTANT things are MISSING that you didn't include but should have? 3. Which 5 features form the MVP — the smallest version where this is actually useful and worth shipping? Justify briefly. 4. For each MVP feature, in one sentence: what is the simplest possible implementation that delivers the value? Format as 4 numbered sections. Be terse and decisive. No hedging. codex 1. **Cut Or Merge** Cut **Decision Ledger**. It is notes with ceremony; important decisions can live inside Event Brief, Run Of Show, Budget, or Checklist items. Merge **Packing And Supply Lists** into **Private Planning Checklist**. “Buy plates,” “borrow cooler,” and “return chairs” are tasks with categories, not a separate product surface. 2. **Missing** **Venue/Vendor Contact Sheet**. Even personal events quickly depend on addresses, phone numbers, booking refs, access notes, deposits, cancellation terms, and arrival windows. **Responsibility Assignment**. Personal events are usually coordinated with a partner, family, or friends; every task, cost, and run-of-show item needs a clear owner. 3. **MVP Features** **Event Brief**. Without a date, place, size, budget, and purpose, the rest of the app has no anchor. **Guest List With RSVP State**. Headcount drives food, budget, venue, seating, lodging, and communication. **Private Planning Checklist**. The app must help users know what to do next, not just store event data. **Deadline Timeline**. This turns the checklist into urgency and prevents late planning failures. **Budget Buckets**. Money is one of the fastest ways casual plans become stressful, and even rough visibility is valuable. 4. **Simplest MVP Implementation** **Event Brief:** One editable form with event type, title, dates, location, estimated guests, rough budget, and success notes. **Guest List With RSVP State:** A table of guests with household name, RSVP status, party size, dietary notes, and lodging flag. **Private Planning Checklist:** A simple task list seeded from event type/date, with due date, owner, category, and done checkbox. **Deadline Timeline:** A chronological view of incomplete checklist items grouped by overdue, this week, this month, and later. **Budget Buckets:** A bucketed list of estimated and actual costs with totals, remaining budget, and paid-by text. 2026-04-27T11:07:45.333919Z ERROR codex_core::session: failed to record rollout items: thread 019dce9f-829c-7551-bc45-d2fd557b8f58 not found tokens used 3,703 1. **Cut Or Merge** Cut **Decision Ledger**.
