n8n GitHub Issue Triage with OpenAI: Draft Implementation Plan

Turn every new GitHub issue into a ready-to-ship implementation plan

This n8n workflow watches your GitHub repository for newly opened issues, uses an OpenAI chat model to draft a structured Markdown implementation plan, and automatically posts it back to the same issue as a comment—so you can triage faster and align the team sooner.

What this workflow does

• Triggers on GitHub issue events for your configured repository.
• Runs only when the issue action is “opened” to avoid generating plans for edits, labels, or closures.
• Extracts and normalizes issue context including title, body, number, URL, author, and repository.
• Sends the issue context to an OpenAI chat model to generate a Markdown plan containing a summary, type, priority, acceptance criteria, step-by-step implementation, risks, and open questions.
• Formats the output into a readable GitHub comment with a short disclaimer.
• Creates the comment on the originating GitHub issue using GitHub credentials.

Use cases

• Speed up GitHub issue triage by converting raw bug reports and feature requests into actionable plans.
• Help SaaS operators standardize how work is planned (priority, acceptance criteria, risks) directly in the issue thread.
• Reduce team back-and-forth by capturing open questions and assumptions early with an OpenAI-generated proposal.

Technical details

• GitHub Trigger: listens for issue events in the selected repository.
• Conditional logic: uses if to proceed only when action equals opened.
• Data shaping: uses set and code to extract and normalize title, body, metadata, and URLs.
• OpenAI chat model: generates the structured Markdown implementation plan.
• GitHub integration: posts the resulting Markdown as a comment to the same issue.
• Includes a sticky note for workflow guidance.

Setup checklist

• Add GitHub API credentials with permission to read issues and create issue comments.
• Set the GitHub owner/repository in the trigger.
• Add an OpenAI API credential and choose a chat model in the OpenAI chat model node.
• Deploy and let n8n handle the triage automatically.
