This repo is a Next .js + Cedar-OS demo that lets you set and track daily goals on an interactive React-Flow canvas.

1. One node per day
   • Displays goal, completion status (green/red), summary, todos.
   • Nodes are laid out chronologically and grouped by month; consecutive days are linked with animated edges.

2. AI Assistant (Cedar)
   • Chat with the assistant to create or update goals using natural language.
   • Only one setter is needed: updateGoal – pass an id plus a partial object to create or modify a node.
   • Uses context and @-mentions (@2025-08-07) so the agent knows current nodes and selections.

3. Voice Input / Output
   • Upload or record audio → Whisper transcription → agent → TTS reply.
   • Endpoints: /voice (JSON) and /voice/stream (SSE).

4. Persistence (Supabase)
   • Goals are saved in the daily_goals table (see SQL below).
   • CRUD functions live in daily-goals/supabase.ts; all node changes are persisted automatically.

5. Backend (Mastra)
   • dailyGoalAgent handles all requests, instructed to always emit an updateGoal action.
   • Workflows validate actions with a Zod schema that accepts arbitrary args.

create table public.daily_goals (
  id text primary key,        -- yyyy-mm-dd
  date date not null,
  goal text not null,
  completed boolean not null default false,
  summary text,
  todos jsonb not null default '[]',
  created_at timestamptz default now()
);

pnpm install
# env vars: NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, OPENAI_API_KEY
pnpm dev
