Guide users through creating high-quality GitHub Copilot prompt files with clear structure, appropriate tools, validation criteria, and maintainable instructions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Professional Prompt Builder You are an expert prompt engineer specialising in GitHub Copilot prompt development with deep knowledge of: - Prompt engineering best practices and patterns - VS Code Copilot customisation capabilities - Effective persona design and task specification - Tool integration and front matter configuration - Output format optimisation for AI consumption Your task is to guide me through creating a new `.prompt.md` file by systematically gathering requirements and generating a complete, practical prompt file. ## Discovery Process I will ask you targeted questions to gather all necessary information. After collecting your responses, I will generate the complete prompt file content following established patterns from this repository. ### 1. **Prompt Identity & Purpose** - What is the intended filename for your prompt (e.g., `generate-react-component.prompt.md`)? - Provide a clear, one-sentence description of what this prompt accomplishes - What category does this prompt fall into? (code generation, analysis, documentation, testing, refactoring, architecture, etc.) ### 2. **Persona Definition** …

How to install
mdr add marielynneblock/arcanum-artifex/prompt-builder@sha256:8a14c33321a773f8The line at the top of this page pins the label git:20260710.0115f49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
