Automate Prompt Engineering with Github Integration
detail.loadingPreview
Streamline your prompt engineering workflow by automatically loading prompts from a GitHub repository directly into your n8n instance. This workflow ensures your prompts are always up-to-date and dynamically populated with relevant variables.
About This Workflow
This n8n workflow revolutionizes prompt engineering by connecting directly to your GitHub repository. It intelligently fetches prompt files, validates that all necessary variables within the prompts are present in your n8n environment, and then dynamically replaces placeholders with your specified values. This ensures consistency, reduces manual effort, and keeps your AI interactions sharp and contextually relevant. Say goodbye to copy-pasting and hello to automated, robust prompt management.
Key Features
- Automated Prompt Fetching: Directly pull prompt files from any GitHub repository.
- Dynamic Variable Replacement: Seamlessly inject custom variables into your prompts.
- Variable Validation: Ensures all required variables are present before execution, preventing errors.
- Version Control Integration: Leverages GitHub for prompt storage and versioning.
- Customizable Configuration: Easily define repository, file path, and variable values within n8n.
How To Use
- Manual Trigger: Start the workflow by clicking the 'Test workflow' button in n8n.
- Set Variables: Configure the 'setVars' node with your GitHub repository details (owner, repo, path, filename) and any other dynamic variables you wish to use.
- Fetch Prompt: The 'GitHub' node retrieves the specified file from your repository.
- Store Prompt: The 'SetPrompt' node stores the fetched prompt content.
- Check Variables: The 'Check All Prompt Vars Present' node analyzes the prompt for placeholders (e.g.,
{{ variableName }}) and verifies if corresponding variables exist in the 'setVars' node. - Conditional Logic: The 'If' node branches the workflow based on whether all prompt variables are present.
- Replace Variables: If all variables are found, the 'replace variables' node dynamically substitutes the placeholders in the prompt with their corresponding values.
- Set Completed Prompt: The 'Set Completed Prompt' node stores the fully populated prompt.
- Error Handling: If any prompt variables are missing, the workflow proceeds to the 'Stop and Error' node, clearly indicating which variables are missing.
