Connect **Google Sheets** and **Slack** credentials in n8n.\n2. Replace placeholders (``, ``, ``).\n3. Adjust the AI review prompt or lint rules as needed.\n4. Activate the workflow \u2014 reviews will start automatically whenever new code is added to the sheet.\n\n### Requirements\n- Google Sheets and Slack integrations enabled\n- A configured AI node (Gemini, OpenAI, or compatible)\n- Proper permissions to write to your target Google Sheet\n\n### How to customize\n- Add more linting rules (naming conventions, spacing, forbidden APIs)\n- Extend the AI prompt for project-specific guidelines\n- Customize the Slack message formatting\n- Export analytics to a dashboard (e.g., Notion or Data Studio)\n\n### Why it\u2019s valuable\nThis workflow brings **realistic, team-oriented AI-assisted code review** to n8n \u2014 combining the speed of automated linting with the nuance of human-style feedback. It saves time, improves code quality, and keeps your team\u2019s review history transparent and centralized." }, "typeVersion": 1 }, { "id": "3198d5f4-06c1-43a4-8e88-a76c9c67eff9", "name": "Sticky Note", "type": "n8n-nodes-base.stickyNote", "position": [ 96, 176 ], "parameters": { "content": "Add coding conventions and design documents as tools." }, "typeVersion": 1 } ], "active": false, "settings": { "executionOrder": "v1" }, "versionId": "64769cf0-2122-4615-a487-6ea7fc3dc2b1", "connections": { "AI Agent": { "main": [ [ { "node": "Format Review Output", "type": "main", "index": 0 } ] ] }, "Lint Check": { "main": [ [ { "node": "AI Agent", "type": "main", "index": 0 } ] ] }, "Format Review Output": { "main": [ [ { "node": "Aggregate Review Stats", "type": "main", "index": 0 } ] ] }, "Aggregate Review Stats": { "main": [ [ { "node": "\u30ec\u30d3\u30e5\u30fc\u7d50\u679c\u6574\u5f62", "type": "main", "index": 0 } ] ] }, "Google Gemini Chat Model": { "ai_languageModel": [ [ { "node": "AI Agent", "type": "ai_languageModel", "index": 0 } ] ] }, "\u30ec\u30d3\u30e5\u30fc\u7d50\u679c\u6574\u5f62": { "main": [ [ { "node": "\u30ec\u30d3\u30e5\u30fc\u7d50\u679c\u66f8\u304d\u8fbc\u307f", "type": "main", "index": 0 } ] ] }, "\u30b3\u30fc\u30c9\u5165\u529b\u30b7\u30fc\u30c8\u76e3\u8996": { "main": [ [ { "node": "Lint Check", "type": "main", "index": 0 } ] ] }, "\u30ec\u30d3\u30e5\u30fc\u7d50\u679c\u66f8\u304d\u8fbc\u307f": { "main": [ [ { "node": "Post Review Summary", "type": "main", "index": 0 } ] ] }, "Get row(s) in sheet in Google Sheets": { "ai_tool": [ [ { "node": "AI Agent", "type": "ai_tool", "index": 0 } ] ] } } }
