How It Works (Step-by-Step) 1. GitHub Trigger Node Type**: n8n-nodes-base.githubTrigger Purpose**: Initiates the workflow on GitHub push events. Repo**: akhilv77/relevance Output**: JSON with commit and repo details. 2. Parser Node Type**: n8n-nodes-base.set Purpose**: Extracts key info (repo ID, name, commit SHA, file changes). 3. HTTP Request Node Type**: n8n-nodes-base.httpRequest Purpose**: Fetches commit diff details using GitHub API. Auth**: GitHub OAuth2 API. 4.

Recipient**: akhilgadiraju@gmail.com 10. End Workflow Node Type**: n8n-nodes-base.noOp Purpose**: Marks the end. Customization Tips GitHub Trigger**: Change repo/owner or trigger events. HTTP Request**: Modify endpoint to get specific data. AI Agent**: Update the prompt to focus on different review aspects. Groq Model**: Swap for other supported LLMs if needed. Memory**: Use dynamic session key for per-commit reviews. Email**: Change recipient or email styling. Error Handling Use Error Trigger nodes to handle failures in: GitHub API requests LLM generation Email delivery Use Cases Instant AI-powered feedback on code pushes. Pre-human review suggestions. Security and standards enforcement. Developer onboarding assistance.
