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: 019dce9e-e6f3-7752-b286-2b211741bbe5 -------- user Brainstorm 10-14 CORE features for "eventa", a small opinionated event-planning app for personal use (parties, dinners, weekend trips, weddings, birthdays). It is NOT trying to compete with Eventbrite or Partiful. It is for a single user or family to plan their own events well. Be specific and opinionated. Avoid bloat. Each feature: one short title, one sentence describing what it does, one sentence on why it matters / what problem it solves. Skip generic stuff like "user accounts" or "responsive design" — focus on event-planning-specific functionality. Format as a markdown numbered list. Be concise. codex 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. 2026-04-27T11:07:13.202141Z ERROR codex_core::session: failed to record rollout items: thread 019dce9e-e6f3-7752-b286-2b211741bbe5 not found tokens used 2,801 1. **Event Brief** Capture the event’s purpose, date range, location, rough size, budget, and “done means” in one compact planning brief.
