It checks for any unprocessed feedback and feeds it to the **AI agent**\n3. The agent can edit the val's own source code (e.g. add new data sources, change the script format)\n4. Then **`generate-podcast.ts`** fetches live data and generates a TTS episode via ElevenLabs\n5. The episode is stored as a blob and served via **`feed.ts`** as an RSS feed\n\nSubscribe in your podcast app. Leave feedback via the web form. The AI agent processes it before the next episode.\n\n## Files\n\n| File | Type | What it does |\n|------|------|-------------|\n| `generate-daily.ts` | interval | Cron trigger — processes feedback, then generates today's episode |\n| `generate-podcast.ts` | script | Fetches data sources, builds script, calls ElevenLabs TTS |\n| `feed.ts` | http | RSS feed, episode audio serving, feedback form (`/feedback`) |\n| `podcast-player.ts` | http | Simple web audio player |\n| `agent.ts` | script | Self-improving AI agent — reads own source, calls Claude, applies code edits |\n| `cover-art.ts` | http | Podcast cover art |\n| `changelog.md` | file | Log of all agent-applied changes |\n| `feature-ideas.md` | file | Future ideas |\n\n## Built-in data sources\n\nOut of the box, the podcast script includes:\n\n- **Weather** — via [Open-Meteo](https://open-meteo.com) (free, no API key). Default: New York. Edit `WEATHER_LOCATIONS` in `generate-podcast.ts` to change.\n- **Prediction markets** — via [Polymarket Gamma API](https://gamma-api.polymarket.com) (free, no API key). Empty by default — uncomment or add event slugs in `POLYMARKET_EVENTS`.\n\nWant more? Just submit feedback like _\"Add top Hacker News stories\"_ or _\"Include Bitcoin price\"_ and the agent will wire it up.\n\n## Setup\n\n1. **Fork this val**\n2. **Add environment variables:**\n\n| Key | Description |\n|-----|-------------|\n| `ELEVEN_LABS_API_KEY` | [ElevenLabs](https://elevenlabs.io) text-to-speech API key |\n| `ANTHROPIC_API_KEY` | [Anthropic](https://anthropic.com) API key for Claude (used by agent) |\n| `TOWNIE_TOKEN` | Val Town API token with write access (used by agent to edit its own files) |\n\n3. **Update `agent.ts`** — change `VAL_UUID` to your forked val's UUID\n4. **Set the interval schedule** on `generate-daily.ts` (e.g. daily at 7am)\n5. **Subscribe** to the RSS feed URL in your podcast app (see below)\n\n## Listening\n\nYour feed URL is the endpoint for `feed.ts` — copy it from the Val Town dashboard.\n\n### Apple Podcasts (iPhone / iPad)\n\n1. Open the **Podcasts** app\n2. Tap **Library** at the bottom\n3. Tap the **⋯** (three dots) in the top-right\n4. Tap **Follow a Show by URL**\n5. Paste your feed URL → tap **Follow**\n\n### Apple Podcasts (Mac)\n\n1. Open **Podcasts** (or iTunes on older macOS)\n2. Click **File** → **Add a Show by URL…**\n3. Paste your feed URL → click **Follow**\n\n### Overcast (iOS)\n\n1. Tap the magnifying glass icon\n2. Tap **Add URL**\n3. Paste your feed URL\n\n### Pocket Casts\n\n1. Go to the **Discover** tab\n2. Paste your feed URL into the search bar\n3. Tap **Subscribe**\n\n### Podcast Addict (Android)\n\n1. Tap **+** → **RSS feed**\n2. Paste your feed URL\n\n### Spotify\n\n⚠️ Spotify does **not** support subscribing to private/custom RSS feeds. You'd need to submit your podcast publicly through [Spotify for Creators](https://creators.spotify.com), which isn't really the point here. Use one of the apps above instead.\n\n## Feedback loop\n\n1. Visit `/feedback` on the feed endpoint (linked in each episode description)\n2. Submit text feedback — it's saved as a blob instantly\n3. Next time `generate-daily.ts` runs, the agent reads all unprocessed feedback\n4. The agent calls Claude with the full val source + your feedback\n5. Claude outputs edit blocks → agent applies them via the Val Town API\n6. Changes are logged in `changelog.md`\n7. The (potentially updated) `generate-podcast.ts` runs to create that day's episode\n\n## Customization\n\nEdit the constants at the top of each file:\n\n- **`generate-podcast.ts`** — `WEATHER_LOCATIONS`, `POLYMARKET_EVENTS`, `ELEVENLABS_VOICE_ID`\n- **`feed.ts`** — `PODCAST_TITLE`, `PODCAST_DESCRIPTION`, `PODCAST_AUTHOR`\n\nOr just submit feedback and let the agent do it for you!\n\n## Blob storage layout\n\n```\nself-improving-podcast/\n episodes/ — MP3 files (2026-03-25-1711234567890.mp3)\n feedback/ — Feedback JSON blobs (timestamp.json)\n agent-runs/ — Agent execution logs\n```\n",[193],"pulls","branches","forks","envVars",{"_205":40,"_207":40},"connections",{"_205":40,"_206":40},"count","unfilledCount","emptyCount",{"_18":192,"_20":193,"_134":194,"_136":-5,"_137":69,"_138":67,"_139":110,"_22":242,"_66":40,"_141":101,"_143":196,"_145":26,"_146":-5,"_218":243,"_90":244},{"_18":186,"_20":187,"_134":188,"_136":-5,"_137":69,"_138":67,"_139":110,"_22":239,"_66":40,"_141":152,"_143":190,"_145":26,"_146":-5,"_218":240,"_90":241},{"_18":180,"_20":181,"_134":182,"_136":-5,"_137":69,"_138":67,"_139":110,"_22":236,"_66":40,"_141":101,"_143":184,"_145":26,"_146":-5,"_218":237,"_90":238},{"_18":174,"_20":175,"_134":176,"_136":-5,"_137":69,"_138":67,"_139":110,"_22":233,"_66":40,"_141":142,"_143":178,"_145":26,"_146":-5,"_218":234,"_90":235},{"_18":168,"_20":169,"_134":170,"_136":-5,"_137":69,"_138":67,"_139":110,"_22":230,"_66":40,"_141":101,"_143":172,"_145":26,"_146":-5,"_218":231,"_90":232},{"_18":162,"_20":163,"_134":164,"_136":-5,"_137":69,"_138":67,"_139":110,"_22":227,"_66":40,"_141":142,"_143":166,"_145":26,"_146":-5,"_218":228,"_90":229},{"_18":155,"_20":156,"_134":157,"_136":-5,"_137":69,"_138":67,"_139":110,"_22":224,"_66":40,"_141":159,"_143":160,"_145":26,"_146":-5,"_218":225,"_90":226},{"_18":148,"_20":149,"_134":150,"_136":-5,"_137":69,"_138":67,"_139":110,"_22":221,"_66":40,"_141":152,"_143":153,"_145":26,"_146":-5,"_218":222,"_90":223},{"_18":132,"_20":133,"_134":135,"_136":-5,"_137":69,"_138":67,"_139":110,"_22":217,"_66":40,"_141":142,"_143":144,"_145":26,"_146":-5,"_218":219,"_90":220},["D",1775500599390],"children",[],[133],["D",1775500599390],[],[149],["D",1775500599390],[],[156],["D",1775500599390],[],[163],["D",1775500599390],[],[169],["D",1775500599390],[],[175],["D",1775500599390],[],[181],["D",1775500599390],[],[187],["D",1775500599390],[],[193],["D",1775500599390],["D",1789683682336],{"_16":17,"_88":84},{"_16":17,"_82":-5,"_83":84,"_33":34,"_85":86,"_87":26},{"_66":67,"_20":68,"_18":69,"_70":19,"_71":72,"_73":74,"_75":28,"_76":77,"_78":79,"_80":21,"_81":17},"ctx",{"_59":-5,"_112":283,"_284":285,"_286":287,"_288":26,"_289":26,"_290":26,"_291":110,"_292":-5,"_293":-7,"_294":-7,"_295":40,"_296":26,"_297":26,"_298":-5,"_299":26,"_300":26,"_301":26,"_302":-5},"ENV",{"_254":255,"_256":257,"_258":68,"_259":260,"_261":262,"_263":264,"_265":266,"_267":268,"_269":270,"_271":272,"_273":274,"_275":276,"_277":278,"_279":280,"_281":282},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","71c1b20804b3232a7e513be260cfffc1932a9e97","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
