Equipped with an OpenAI-powered Agent and integrated audit logging to Google Sheets, it supports operations like listing buckets, copying/deleting files, managing folders, and automatically records every action for compliance and traceability.\n## 👥 Who’s it for\nThis workflow is built for:\n- DevOps engineers who want to manage AWS S3 using natural chat commands.\n- Technical support teams interacting with AWS via Slack, Telegram, etc.\n- Automation engineers building ChatOps tools.\n- Organizations that require **audit logs** for every cloud operation.\n\nUsers don’t need AWS Console or CLI access — just send a message like “Copy file from dev to prod”.\n## ⚙️ How it works / What it does\nThis workflow turns natural chat input into **automated AWS S3 actions** using an OpenAI-powered AI Agent in n8n.\n### 🔁 Workflow Overview:\n1. **Trigger**: A user sends a message in Slack, Telegram, etc.\n2. **AI Agent**: \n   - Interprets the message\n   - Calls one of 6 S3 tools:\n     - `ListBuckets`\n     - `ListObjects`\n     - `CopyObject`\n     - `DeleteObject`\n     - `ListFolders`\n     - `CreateFolder`\n3. **S3 Action**: Performs the requested AWS S3 operation.\n4. **Audit Log**: Logs the tool call to Google Sheets using `AddAuditLog`:\n   - Includes timestamp, tool used, parameters, prompt, reasoning, and user info.\n\n## 🛠️ How to set up\n### Step-by-step Setup:\n1. **Webhook Trigger**\n   - Slack, Telegram, or custom chat platform → connects to n8n.\n\n2. **OpenAI Agent**\n   - Model: `gpt-4` or `gpt-3.5-turbo`\n   - Memory: Simple Memory Node\n   - Prompt: Instructs agent to always follow tool calls with an `AddAuditLog` call.\n\n3. **AWS S3 Nodes**\n   - Configure each tool with AWS credentials.\n   - Tools:\n     - `getAll: bucket`\n     - `getAll: file`\n     - `copy: file`\n     - `delete: file`\n     - `getAll: folder`\n     - `create: folder`\n\n4. **Google Sheets Node**\n   - Sheet: `AWS S3 Audit Logs`\n   - Operation: `Append or Update Row`\n   - Columns (must match input keys):  \n     - `timestamp`, `tool`, `status`, `chat_prompt`, `parameters`, `user_name`, `tool_call_reasoning`\n\n5. **Agent Tool Definitions**\n   - Include `AddAuditLog` as a 7th tool.\n   - Agent calls it **immediately after every S3 action** (except when logging itself).\n\n## ✅ Requirements\n- [ ] n8n instance with AI Agent feature\n- [ ] OpenAI API Key\n- [ ] AWS IAM user with S3 access\n- [ ] Google Sheet with required columns\n- [ ] Chat integration (Slack, Telegram, etc.)\n\n## 🧩 How to customize the workflow\n| Feature              | Customization Tip                                            |\n|----------------------|--------------------------------------------------------------|\n| 🌎 Multi-region S3   | Let users include region in the message or agent memory      |\n| 🛡️ Restricted actions| Use memory/user ID to limit delete/copy actions              |\n| 📁 Folder filtering  | Extend `ListObjects` with prefix/suffix filters              |\n| 📤 Upload file       | Add `PutObject` with pre-signed URL support                  |\n| 🧾 Extra logging     | Add IP, latency, error trace to audit logs                   |\n| 📊 Reporting         | Link Google Sheet to Looker Studio for audit dashboards      |\n| 🚨 Security alerts   | Notify via Slack/Email when `DeleteObject` is triggered      |"
