GitHub - Add Comment

---

Description

The GitHub: Add Comment node allows your workflows to interact directly with developers and users on GitHub by posting messages to specific Issues or Pull Requests. It authenticates using your connected GitHub account so that comments appear to come directly from you or your bot.

Crucially, this node serves a dual purpose: it can be executed as a direct step in a linear workflow, or it can be passed as a Tool into an LLM node. When provided as a tool, your AI agents can autonomously decide when to leave a comment and dynamically generate the response based on the conversation context.

Common Use Cases

• Autonomous Code Reviewers: Passing this node as a tool to an LLM so it can read a Pull Request and automatically post constructive feedback or approve the changes.
• Automated Triage & Support: Having an AI agent review newly opened bug reports and use this node to automatically ask the user for missing information (e.g., "Could you please provide the error logs?").
• Welcome Messages: Triggering a workflow when a new contributor opens their first PR, and using this node to instantly post a standardized welcome message and a link to your contribution guidelines.
