Delivers a concise digest across **Geopolitics, Current Affairs, Sports, Trends, and AI**.\n\n## Architecture\n\n```mermaid\ngraph LR\n C[cron.ts — 6:30 AM UTC] -->|calls Claude + web search| B[Blob Storage]\n A[api.ts — HTTP] -->|GET /| B\n A -->|POST / question| CL[Claude API]\n P[Phone App] -->|HTTP| A\n```\n\n## Endpoints\n\n| Method | Path | Description |\n|--------|------|-------------|\n| `GET` | `/` | Returns the latest stored digest |\n| `POST` | `/` | Proxies a chat question to Claude (auto-enables web search for time-sensitive queries) |\n\n### GET response\n```json\n{ \"digest\": [{ \"topic\": \"AI\", \"headline\": \"...\", \"body\": \"...\", \"fetched\": 1716000000000 }] }\n```\n\n### POST request / response\n```json\n// Request\n{ \"question\": \"What happened in the Champions League today?\" }\n// Response\n{ \"answer\": \"...\" }\n```\n\n## Setup\n\n1. Add your `ANTHROPIC_KEY` environment variable (your `sk-ant-api03-...` key)\n2. The cron runs daily at 06:30 UTC — adjust in the interval settings\n3. Point your phone app at the HTTP endpoint URL\n\n## Files\n\n- `api.ts` — HTTP handler (serves digest + proxies chat)\n- `cron.ts` — Interval job that builds the daily digest\n- `lib/claude.ts` — Shared Claude API helper\n- `lib/config.ts` — Model, topics, and blob key config\n",[177],"669ed1ca-54a8-11f1-b054-ee650bb23af1","lib","669ed2b0-54a8-11f1-b054-ee650bb23af1",1,["D",1779321767798],"directory",[184],"pulls","branches","forks","envVars",{"_197":186,"_199":66},"connections",{"_197":66,"_198":66},"count","unfilledCount","emptyCount",{"_46":183,"_37":184,"_35":185,"_144":-5,"_44":45,"_43":186,"_146":62,"_41":245,"_13":66,"_38":188,"_39":-5,"_29":30,"_149":-5,"_210":246,"_32":247},{"_46":237,"_37":238,"_35":239,"_144":185,"_44":45,"_43":240,"_146":62,"_41":241,"_13":66,"_38":233,"_39":242,"_29":30,"_149":-5,"_210":243,"_32":244},{"_46":228,"_37":229,"_35":230,"_144":185,"_44":45,"_43":231,"_146":30,"_41":232,"_13":66,"_38":233,"_39":234,"_29":30,"_149":-5,"_210":235,"_32":236},{"_46":176,"_37":177,"_35":178,"_144":-5,"_44":45,"_43":179,"_146":30,"_41":225,"_13":66,"_38":26,"_39":181,"_29":30,"_149":-5,"_210":226,"_32":227},{"_46":169,"_37":170,"_35":60,"_144":-5,"_44":45,"_43":171,"_146":30,"_41":222,"_13":66,"_38":173,"_39":174,"_29":30,"_149":-5,"_210":223,"_32":224},{"_46":161,"_37":162,"_35":163,"_144":-5,"_44":45,"_43":164,"_146":62,"_41":219,"_13":66,"_38":166,"_39":167,"_29":30,"_149":-5,"_210":220,"_32":221},{"_46":158,"_37":33,"_35":36,"_144":-5,"_44":45,"_43":14,"_146":62,"_41":216,"_13":66,"_38":26,"_39":40,"_29":30,"_149":-5,"_210":217,"_32":218},{"_46":151,"_37":152,"_35":153,"_144":-5,"_44":45,"_43":154,"_146":30,"_41":213,"_13":66,"_38":26,"_39":156,"_29":30,"_149":-5,"_210":214,"_32":215},{"_46":141,"_37":142,"_35":143,"_144":-5,"_44":45,"_43":145,"_146":62,"_41":209,"_13":66,"_38":26,"_39":148,"_29":30,"_149":-5,"_210":211,"_32":212},["D",1779322991464],"children",[],[142],["D",1779322988796],[],[152],["D",1779323000504],[],[33],["D",1779321785691],[],[162],["D",1779321782093],[],[170],["D",1779321797491],[],[177],"685fe33c-54a8-11f1-b054-ee650bb23af1","config.ts","685fe436-54a8-11f1-b054-ee650bb23af1",2,["D",1779321770746],"script","export const MODEL = \"claude-sonnet-4-20250514\";\nexport const TOPICS = [\"Geopolitics\", \"Current Affairs\", \"Sports\", \"Trends\", \"AI\"];\nexport const BLOB_KEY = \"briefing_digest\";\n",[],[184,229],"6a610fd0-54a8-11f1-85c8-ee650bb23af1","claude.ts","6a611084-54a8-11f1-85c8-ee650bb23af1",3,["D",1779321774108],"import { MODEL } from \"./config.ts\";\n\nconst ANTHROPIC_KEY = Deno.env.get(\"ANTHROPIC_KEY\");\n\nexport async function callClaude(\n messages: { role: string;
