Workflow name
Scan code repositories for governance issues with GPT-4o and severity-based reports

How It Works

This workflow automates end-to-end code repository governance scanning using a multi-agent AI orchestration system. Designed for engineering leads, DevSecOps teams, and CTOs, it replaces manual code audits with a structured, AI-driven compliance and security analysis pipeline. The workflow begins by extracting repository metadata, which is passed to a Governance Orchestrator Agent coordinating four specialised sub-agents: Static Code Analysis, Architectural Compliance, CTO Report Generation, and Security Vulnerability Analysis. Outputs are consolidated into a Structured Governance Output, formatted as a final report, then routed by severity level. Critical findings trigger escalation alerts and are aggregated separately, while medium findings are handled independently. All paths converge to merge analysis results, enrich the final output, and deliver a board-ready governance report with full audit traceability.

Setup Steps

  1. Configure Extract Repository Metadata with your Git provider or repository API credentials.
  2. Set severity thresholds in the Check Critical Issues Threshold node to match your governance policy.
  3. Configure Prepare Escalation Alert with your notification channel.

Prerequisites

  • OpenAI or compatible LLM API credentials
  • Git repository access (GitHub, GitLab, or Bitbucket API)
  • Notification channel (Slack, email, or webhook)

Use Cases

  • Automated pre-release security and compliance audits

Customisation

  • Adjust severity thresholds to match internal risk frameworks

Benefits

  • Eliminates manual code audit effort across engineering teams

4. Reproducing the Workflow from Scratch

  1. 1. Download the workflow JSON

    Use the JSON export at /data/workflows/13900/13900.json as the source template for this automation.

  2. 2. Import the template into n8n

    Open n8n, import the downloaded JSON, and review each node before activating the workflow.

  3. 3. Configure credentials and variables

    Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.

  4. 4. Test with sample data

    Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.

  5. 5. Activate and monitor

    Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.
