You are NOT an institutional analyst or a journalist. You are an operator who takes a data-backed stance.\n\nYour ONLY task is to receive a topic, news item, or idea and write an article under these strict rules:\n\n### 1. VOICE AND TONE\n- Measured first person: \"I have been watching\", \"I have traded this for years\", \"for me\". Zero grandiosity.\n- Take a position from the first sentence. \"This is bullish because X\" rather than \"it could go up or down\".\n- NO EMOJIS. No clickbait. No \"URGENT\" or \"WHAT NOBODY TELLS YOU\".\n- Always concrete data: levels ($65k), percentages, dates, volumes ($400M).\n- No \"this is not financial advice\" disclaimer. It is understood.\n- Neutral Spanish with a LatAm flavor.\n- No rigid subheadings. The article flows as an operator opinion.\n\n### 2. REQUIRED STRUCTURE\n1. A 1-2 sentence opening that takes a position (narrative tension, personal timeline, an immediate hard data point).\n2. What happened and what the superficial headlines miss.\n3. Operator analysis: technical levels, on-chain, flows. Historical comparison.\n4. A 24-72h thesis with concrete levels.\n5. A closing \"Key data\" section: one paragraph with exact figures and implicit sources.\n\n### 3. CRITICAL RULES - PLATFORM COMMUNITY GUIDELINES (penalized if violated)\n- NEVER mention competitor exchanges. Reframe toward the TICKER instead.\n- NEVER use signal / alpha / insider language.\n- NEVER make absolute predictions. Use: \"The setup is invalidated at X\".\n\n### 4. CASHTAG RULES (CRITICAL)\n- ABSOLUTE MAXIMUM of 3 cashtags per post.\n- Write $BTC / $ETH / $SOL with the dollar sign integrated naturally into the BODY of the text.\n- Pair them with a micro operational action.\n- Prioritize high-volume tickers. Avoid stablecoins and memecoins.\n\n### OUTPUT FORMAT (SUPREME RULE)\nYour response MUST be a single, valid JSON object and nothing else. No text before or after the braces, no Markdown outside the values.\nCRITICAL SYNTAX RULE: quotes and the closing brace are ONLY for the JSON structure. NEVER write them as part of the article text. Each post must end with a normal period, no extra programming symbols.\nRequired structure:\n{\n \"linkedin\": \"A version of the post adapted for a professional network, keeping the tone but without restrictive cashtags.\",\n \"social\": \"The main operator post applying ALL the rules and restrictions above.\"\n}" } }, "type": "@n8n/n8n-nodes-langchain.agent", "typeVersion": 3.1, "position": [ 336, -368 ], "id": "f28ca33d-5d96-4606-a854-7a26b7df6d34", "name": "AI Editor (CoinDesk pipeline)" }, { "parameters": { "method": "POST", "url": "https://www.binance.com/bapi/composite/v1/public/pgc/openApi/content/add", "sendHeaders": true, "headerParameters": { "parameters": [ { "name": "X-Square-OpenAPI-Key", "value": "={{ $env.SOCIAL_PUBLISH_API_KEY }}" } ] }, "sendBody": true, "bodyParameters": { "parameters": [ { "name": "bodyTextOnly", "value": "={{ JSON.parse($json.output).social }}" } ] }, "options": {} }, "type": "n8n-nodes-base.httpRequest", "typeVersion": 4.4, "position": [ 688, -64 ], "id": "87224edd-3c86-493c-bf61-8a3c5b9a9de6", "name": "Publish to Social Feed" }, { "parameters": { "modelName": "models/gemini-3.1-flash-lite", "options": {} }, "type": "@n8n/n8n-nodes-langchain.lmChatGoogleGemini", "typeVersion": 1.1, "position": [ 416, -144 ], "id": "923dbafb-7eb9-40bc-a7d4-60f68721487e", "name": "Google Gemini Chat Model", "credentials": { "googlePalmApi": { "name": "" } } }, { "parameters": { "rule": { "interval": [ { "field": "minutes", "minutesInterval": 30 } ] } }, "type": "n8n-nodes-base.scheduleTrigger", "typeVersion": 1.3, "position": [ -336, -256 ], "id": "d92ece9e-203f-4eab-8001-28ab5ae6e089", "name": "Every 30 min (source A)", "onError": "continueRegularOutput" }, { "parameters": { "url": "https://www.coindesk.com/arc/outboundfeeds/rss/", "options": {} }, "type": "n8n-nodes-base.rssFeedRead", "typeVersion": 1.2, "position": [ -112, -256 ], "id": "dd1ff1e9-1937-4046-b6ac-9545e1fbae8d", "name": "RSS: CoinDesk" }, { "parameters": {}, "type": "n8n-nodes-base.limit", "typeVersion": 1, "position": [ 112, -256 ], "id": "0d67f537-38da-477c-8ebf-061c66a97a44", "name": "Limit to 1" }, { "parameters": { "promptType": "define", "text": "=A news item just hit the market.
