    "description": "## 📊 Description\nEnsure your GitHub repositories stay configuration-accurate and documentation-compliant with this intelligent AI-powered validation workflow. 🤖\nThis automation monitors repository updates, compares configuration files against documentation references, detects inconsistencies, and alerts your team instantly—streamlining DevOps and compliance reviews. ⚡\n\n## What This Template Does\n- Step 1: Triggers automatically on GitHub push or pull_request events. 🔄\n- Step 2: Fetches both configuration files (config/app-config.json and faq-config.json) from the repository. 📂\n- Step 3: Uses GPT-4o-mini to compare configurations and detect mismatches, missing keys, or deprecated fields. 🧠\n- Step 4: Categorizes issues by severity—critical, high, medium, or low—and generates actionable recommendations. 🚨\n- Step 5: Logs all discrepancies to Google Sheets for tracking and audit purposes. 📑\n- Step 6: Sends Slack alerts summarizing key issues and linking to the full report. 💬\n\n## Key Benefits\n✅ Prevents production incidents due to config drift\n ✅ Ensures documentation stays in sync with code changes\n ✅ Reduces manual review effort with AI-driven validation\n ✅ Improves team response with Slack-based alerts\n ✅ Maintains audit logs for compliance and traceability\n\n## Features\n- Real-time GitHub webhook integration\n- AI-powered config comparison using GPT-4o-mini\n- Severity-based issue classification\n- Automated Google Sheets logging\n- Slack alerts with detailed issue context\n- Error handling for malformed JSON or parsing issues\n\n## Requirements\n- GitHub OAuth2 credentials with repo and webhook permissions\n- OpenAI API key (GPT-4o-mini or compatible model)\n- Google Sheets OAuth2 credentials\n- Slack API token with chat:write permissions\n\n## Target Audience\n- DevOps teams ensuring consistent configuration across environments\n- Engineering leads maintaining documentation accuracy\n- QA and Compliance teams tracking configuration changes and risks\n\n## Setup Instructions\n- Create GitHub OAuth2 credentials and enable webhook access.\n- Connect your OpenAI API key under credentials.\n- Add your Google Sheets and Slack integrations.\n- Update file paths (config/app-config.json and faq-config.json) if your repo uses different names.\n- Activate the workflow — it will start validating on every push or PR. 🚀\n",
