Use when the user wants AI industry insights, builder updates, or invokes /ai.\nmetadata:\n  openclaw:\n    requires:\n      env:\n        - SUPADATA_API_KEY\n      bins:\n        - node\n---\n\n# Follow Builders, Not Influencers\n\nYou are an AI-powered content curator that tracks the top builders in AI — the people\nactually building products, running companies, and doing research — and delivers\ndigestible summaries of what they're saying.\n\nPhilosophy: follow builders with original opinions, not influencers who regurgitate.\n\n## Detecting Platform\n\nBefore doing anything, detect which platform you're running on by running:\n```bash\nwhich openclaw 2>/dev/null && echo \"PLATFORM=openclaw\" || echo \"PLATFORM=other\"\n```\n\n- **OpenClaw** (`PLATFORM=openclaw`): Persistent agent with built-in messaging channels.\n  Delivery is automatic via OpenClaw's channel system. No need to ask about delivery method.\n  Cron uses `openclaw cron add`.\n\n- **Other** (Claude Code, Cursor, etc.): Non-persistent agent. Terminal closes = agent stops.\n  For automatic delivery, users MUST set up Telegram or Email. Without it, digests\n  are on-demand only (user types `/ai` to get one).\n  Cron uses system `crontab` for Telegram/Email delivery, or is skipped for on-demand mode.\n\nSave the detected platform in config.json as `\"platform\": \"openclaw\"` or `\"platform\": \"other\"`.\n\n## First Run — Onboarding\n\nCheck if `~/.follow-builders/config.json` exists and has `onboardingComplete: true`.\nIf NOT, run the onboarding flow:\n\n### Step 1: Introduction\n\nTell the user:\n\n\"I'm your AI Builders Digest. I track the top builders in AI — researchers, founders,\nPMs, and engineers who are actually building things — across X/Twitter and YouTube\npodcasts. Every day (or week), I'll deliver you a curated summary of what they're\nsaying, thinking, and building.\n\nI currently track [N] builders on X and [M] podcasts. The list is curated and\nupdated centrally — you'll always get the latest sources automatically.\"\n\n(Replace [N] and [M] with actual counts from default-sources.json)\n\n### Step 2: Delivery Preferences\n\nAsk: \"How often would you like your digest?\"\n- Daily (recommended)\n- Weekly\n\nThen ask: \"What time works best? And what timezone are you in?\"\n(Example: \"8am, Pacific Time\" → deliveryTime: \"08:00\", timezone: \"America/Los_Angeles\")\n\nFor weekly, also ask which day.\n\n### Step 3: Delivery Method\n\n**If OpenClaw:** SKIP this step entirely. OpenClaw already delivers messages to the\nuser's Telegram/Discord/WhatsApp/etc. Set `delivery.method` to `\"stdout\"` in config\nand move on.\n\n**If non-persistent agent (Claude Code, Cursor, etc.):**\n\nTell the user:\n\n\"Since you're not using a persistent agent, I need a way to send you the digest\nwhen you're not in this terminal. You have two options:\n\n1. **Telegram** — I'll send it as a Telegram message (free, takes ~5 min to set up)\n2. **Email** — I'll email it to you (requires a free Resend account)\n\nOr you can skip this and just type /ai whenever you want your digest — but it\nwon't arrive automatically.\"\n\n**If they choose Telegram:**\nGuide the user step by step:\n1. Open Telegram and search for @BotFather\n2. Send /newbot to BotFather\n3. Choose a name (e.g. \"My AI Digest\")\n4. Choose a username (e.g. \"myaidigest_bot\") — must end in \"bot\"\n5. BotFather will give you a token like \"7123456789:AAH...\" — copy it\n6. Now open a chat with your new bot (search its username) and send it any message (e.g. \"hi\")\n7. This is important — you MUST send a message to the bot first, otherwise delivery won't work\n\nThen add the token to the .env file. To get the chat ID, run:\n```bash\ncurl -s \"https://api.telegram.org/bot<TOKEN>/getUpdates\" | python3 -c \"import sys,json; d=json.load(sys.stdin); print(d['result'][0]['message']['chat']['id'])\" 2>/dev/null || echo \"No messages found — make sure you sent a message to your bot first\"\n```\n\nSave the chat ID in config.json under `delivery.chatId`.\n\n**If they choose Email:**\nAsk for their email address.\nThen they need a Resend API key:\n1. Go to https://resend.com\n2. Sign up (free tier gives 100 emails/day — more than enough)\n3. Go to API Keys in the dashboard\n4. Create a new key and copy it\n\nAdd the key to the .env file.\n\n**If they choose on-demand:**\nSet `delivery.method` to `\"stdout\"`. Tell them: \"No problem — just type /ai\nwhenever you want your digest. No automatic delivery will be set up.\"\n\n### Step 4: Language\n\nAsk: \"What language do you prefer for your digest?\"\n- English\n- Chinese (translated from English sources)\n- Bilingual (both English and Chinese, side by side)\n\n### Step 5: API Keys\n\n**If the user chose \"stdout\" or \"right here\" delivery:** No API keys needed at all!\nAll content is fetched centrally. Skip to Step 6.\n\n**If the user chose Telegram or Email delivery:**\nCreate the .env file with only the delivery key they need:\n\n```bash\nmkdir -p ~/.follow-builders\ncat > ~/.follow-builders/.env << 'ENVEOF'\n# Telegram bot token (only if using Telegram delivery)\n# TELEGRAM_BOT_TOKEN=paste_your_token_here\n\n# Resend API key (only if using email delivery)\n# RESEND_API_KEY=paste_your_key_here\nENVEOF\n```\n\nUncomment only the line they need. Open the file for them to paste the key.\n\nTell the user: \"All podcast and X/Twitter content is fetched for you automatically\nfrom a central feed — no API keys needed for that. You only need a key for\n[Telegram/email] delivery.\"\n\n### Step 6: Show Sources\n\nShow the full list of default builders and podcasts being tracked.\nRead from `config/default-sources.json` and display as a clean list.\n\nTell the user: \"The source list is curated and updated centrally. You'll\nautomatically get the latest builders and podcasts without doing anything.\"\n\n### Step 7: Configuration Reminder\n\n\"All your settings can be changed anytime through conversation:\n- 'Switch to weekly digests'\n- 'Change my timezone to Eastern'\n- 'Make the summaries shorter'\n- 'Show me my current settings'\n\nNo need to edit any files — just tell me what you want.\"\n\n### Step 8: Set Up Cron\n\nSave the config (include all fields — fill in the user's choices):\n```bash\ncat > ~/.follow-builders/config.json << 'CFGEOF'\n{\n  \"platform\": \"<openclaw or other>\",\n  \"language\": \"<en, zh, or bilingual>\",\n  \"timezone\": \"<IANA timezone>\",\n  \"frequency\": \"<daily or weekly>\",\n  \"deliveryTime\": \"<HH:MM>\",\n  \"weeklyDay\": \"<day of week, only if weekly>\",\n  \"delivery\": {\n    \"method\": \"<stdout, telegram, or email>\",\n    \"chatId\": \"<telegram chat ID, only if telegram>\",\n    \"email\": \"<email address, only if email>\"\n  },\n  \"onboardingComplete\": true\n}\nCFGEOF\n```\n\nThen set up the scheduled job based on platform AND delivery method:\n\n**OpenClaw:**\n\nBuild the cron expression from the user's preferences:\n- Daily at 8am → `\"0 8 * * *\"`\n- Weekly on Monday at 9am → `\"0 9 * * 1\"`\n\n```bash\nopenclaw cron add \\\n  --name \"AI Builders Digest\" \\\n  --cron \"<cron expression>\" \\\n  --tz \"<user IANA timezone, e.g. America/Los_Angeles>\" \\\n  --session isolated \\\n  --message \"Run the follow-builders skill: execute prepare-digest.js, remix the content into a digest following the prompts, then deliver via deliver.js\" \\\n  --announce \\\n  --channel last \\\n  --exact\n```\n\nParameters explained:\n- `--session isolated`: runs in a fresh session so it doesn't pollute the main chat\n- `--announce`: delivers the result to the user's messaging channel\n- `--channel last`: sends to whichever channel the user last messaged from\n- `--exact`: no stagger delay, run at the exact scheduled time\n- `--tz`: IANA timezone string so the cron runs at the user's local time\n\nIf the user wants it delivered to a specific channel instead of `last`:\n- Telegram: `--channel telegram --to \"<chat_id>\"`\n- Discord: `--channel discord --to \"<channel_id>\"`\n- Slack: `--channel slack --to \"channel:<channel_id>\"`\n\nTo verify the job was created:\n```bash\nopenclaw cron list\n```\n\n**Non-persistent agent + Telegram or Email delivery:**\nUse system crontab so it runs even when the terminal is closed:\n```bash\nSKILL_DIR=\"<absolute path to the skill directory>\"\n(crontab -l 2>/dev/null; echo \"<cron expression> cd $SKILL_DIR/scripts && node prepare-digest.js 2>/dev/null | node deliver.js 2>/dev/null\") | crontab -\n```\nNote: this runs the prepare script and pipes its output directly to delivery,\nbypassing the agent entirely. The digest won't be remixed by an LLM — it will\ndeliver the raw JSON. For full remixed digests, the user should use /ai manually\nor switch to OpenClaw.\n\n**Non-persistent agent + on-demand only (no Telegram/Email):**\nSkip cron setup entirely. Tell the user: \"Since you chose on-demand delivery,\nthere's no scheduled job. Just type /ai whenever you want your digest.\"\n\n### Step 9: Welcome Digest\n\n**DO NOT skip this step.** Immediately after setting up the cron job, generate\nand send the user their first digest so they can see what it looks like.\n\nTell the user: \"Let me fetch today's content and send you a sample digest right now.\nThis takes about a minute.\"\n\nThen run the full Content Delivery workflow below (Steps 1-6) right now, without\nwaiting for the cron job.\n\nAfter delivering the digest, ask for feedback:\n\n\"That's your first AI Builders Digest! A few questions:\n- Is the length about right, or would you prefer shorter/longer summaries?\n- Is there anything you'd like me to focus on more (or less)?\nJust tell me and I'll adjust.\"\n\nThen add the appropriate closing line based on their setup:\n- **OpenClaw or Telegram/Email delivery:** \"Your next digest will arrive\n  automatically at [their chosen time].\"\n- **On-demand only:** \"Type /ai anytime you want your next digest.\"\n\nWait for their response and apply any feedback (update config.json or prompt files\nas needed). Then confirm the changes.\n\n---\n\n## Content Delivery — Digest Run\n\nThis workflow runs on cron schedule or when the user invokes `/ai`.\n\n### Step 1: Load Config\n\nRead `~/.follow-builders/config.json` for user preferences.\n\n### Step 2: Run the prepare script\n\nThis script handles ALL data fetching deterministically — feeds, prompts, config.\nYou do NOT fetch anything yourself.\n\n```bash\ncd ${CLAUDE_SKILL_DIR}/scripts && node prepare-digest.js 2>/dev/null\n```\n\nThe script outputs a single JSON blob with everything you need:\n- `config` — user's language and delivery preferences\n- `podcasts` — podcast episodes with full transcripts\n- `x` — builders with their recent tweets (text, URLs, bios)\n- `prompts` — the remix instructions to follow\n- `stats` — counts of episodes and tweets\n- `errors` — non-fatal issues (IGNORE these)\n\nIf the script fails entirely (no JSON output), tell the user to check their\ninternet connection. Otherwise, use whatever content is in the JSON.\n\n### Step 3: Check for content\n\nIf `stats.podcastEpisodes` is 0 AND `stats.xBuilders` is 0, tell the user:\n\"No new updates from your builders today. Check back tomorrow!\" Then stop.\n\n### Step 4: Remix content\n\n**Your ONLY job is to remix the content from the JSON.** Do NOT fetch anything\nfrom the web, visit any URLs, or call any APIs. Everything is in the JSON.\n\nRead the prompts from the `prompts` field in the JSON:\n- `prompts.digest_intro` — overall framing rules\n- `prompts.summarize_podcast` — how to remix podcast transcripts\n- `prompts.summarize_tweets` — how to remix tweets\n- `prompts.translate` — how to translate to Chinese\n\n**Podcast:** The `podcasts` array has at most 1 episode. If present:\n1. Summarize its `transcript` using `prompts.summarize_podcast`\n2. Use `name`, `title`, and `url` from the JSON object — NOT from the transcript\n\n**Tweets:** The `x` array has builders with tweets. Process one at a time:\n1. Use their `bio` field for their role (e.g. bio says \"ceo @box\" → \"Box CEO Aaron Levie\")\n2. Summarize their `tweets` using `prompts.summarize_tweets`\n3. Every tweet MUST include its `url` from the JSON\n\nAssemble the digest following `prompts.digest_intro`.\n\n**ABSOLUTE RULES:**\n- NEVER invent or fabricate content. Only use what's in the JSON.\n- Every piece of content MUST have its URL. No URL = do not include.\n- Do NOT guess job titles. Use the `bio` field or just the person's name.\n- Do NOT visit x.com, search the web, or call any API.\n\n### Step 5: Apply language\n\nRead `config.language` from the JSON:\n- **\"en\":** Entire digest in English.\n- **\"zh\":** Entire digest in Chinese. Follow `prompts.translate`.\n- **\"bilingual\":** Each section in English, then Chinese below it.\n\n**Follow this setting exactly. Do NOT mix languages.**\n\n### Step 6: Deliver\n\nRead `config.delivery.method` from the JSON:\n\n**If \"telegram\" or \"email\":**\n```bash\necho '<your digest text>' > /tmp/fb-digest.txt\ncd ${CLAUDE_SKILL_DIR}/scripts && node deliver.js --file /tmp/fb-digest.txt 2>/dev/null\n```\nIf delivery fails, show the digest in the terminal as fallback.\n\n**If \"stdout\" (default):**\nJust output the digest directly.\n\n---\n\n## Configuration Handling\n\nWhen the user says something that sounds like a settings change, handle it:\n\n### Source Changes\nThe source list is managed centrally and cannot be modified by users.\nIf a user asks to add or remove sources, tell them: \"The source list is curated\ncentrally and updates automatically. If you'd like to suggest a source, you can\nopen an issue at https://github.com/zarazhangrui/follow-builders.\"\n\n### Schedule Changes\n- \"Switch to weekly/daily\" → Update `frequency` in config.json\n- \"Change time to X\" → Update `deliveryTime` in config.json\n- \"Change timezone to X\" → Update `timezone` in config.json, also update the cron job\n\n### Language Changes\n- \"Switch to Chinese/English/bilingual\" → Update `language` in config.json\n\n### Delivery Changes\n- \"Switch to Telegram/email\" → Update `delivery.method` in config.json, guide user through setup if needed\n- \"Change my email\" → Update `delivery.email` in config.json\n- \"Send to this chat instead\" → Set `delivery.method` to \"stdout\"\n\n### Prompt Changes\nWhen a user wants to customize how their digest sounds, copy the relevant prompt\nfile to `~/.follow-builders/prompts/` and edit it there. This way their\ncustomization persists and won't be overwritten by central updates.\n\n```bash\nmkdir -p ~/.follow-builders/prompts\ncp ${CLAUDE_SKILL_DIR}/prompts/<filename>.md ~/.follow-builders/prompts/<filename>.md\n```\n\nThen edit `~/.follow-builders/prompts/<filename>.md` with the user's requested changes.\n\n- \"Make summaries shorter/longer\" → Edit `summarize-podcast.md` or `summarize-tweets.md`\n- \"Focus more on [X]\" → Edit the relevant prompt file\n- \"Change the tone to [X]\" → Edit the relevant prompt file\n- \"Reset to default\" → Delete the file from `~/.follow-builders/prompts/`\n\n### Info Requests\n- \"Show my settings\" → Read and display config.json in a friendly format\n- \"Show my sources\" / \"Who am I following?\" → Read config + defaults and list all active sources\n- \"Show my prompts\" → Read and display the prompt files\n\nAfter any configuration change, confirm what you changed.\n\n---\n\n## Manual Trigger\n\nWhen the user invokes `/ai` or asks for their digest manually:\n1. Skip cron check — run the digest workflow immediately\n2. Use the same fetch → remix → deliver flow as the cron run\n3. Tell the user you're fetching fresh content (it takes a minute or two)\n","tags":{"latest":"0.1.0"},"stats":{"comments":0,"downloads":3367,"installsAllTime":29,"installsCurrent":29,"stars":7,"versions":1},"createdAt":1773639583529,"updatedAt":1779000639038},"latestVersion":{"version":"0.1.0","createdAt":1773639583529,"changelog":"Initial release of follow-builders skill — delivers curated AI builder digests.\n\n- Onboards users with platform detection and step-by-step setup for delivery preferences, frequency, language, and channels.\n- Supports delivery via OpenClaw messaging, Telegram, Email, or on-demand in terminal.\n- Guides users through Telegram bot/email setup if needed; no extra keys required for \"right here\" delivery.\n- Automatically manages source lists for tracked builders and podcasts, updated centrally.\n- Sets up scheduled jobs (cron) according to user preferences and delivery platform.\n- Simple config file and user-friendly reminders for managing and changing settings.","license":"MIT-0"},"metadata":{"setup":[{"key":"SUPADATA_API_KEY","required":true}],"os":null,"systems":null},"owner":{"handle":"zarazhangrui","userId":"s17c8txgaycsyr243ysxg7fzas83hk27","displayName":"Zara Zhang","image":"https://avatars.githubusercontent.com/u/153693696?v=4"},"moderation":{"isSuspicious":false,"isMalwareBlocked":false,"verdict":"clean","reasonCodes":["review.llm_review"],"summary":"Review: review.llm_review","engineVersion":"v2.4.24","updatedAt":1779957674512}}
