What problem does it solve? Creating GitHub Copilot instruction files requires knowing the correct file naming, YAML frontmatter with applyTo glob patterns, and prescriptive content structure. This Skill scaffolds properly formatted .instructions.md files so rules auto-load for the right file types without trial and error. ## Core Features & Use Cases - Instruction Scaffolding: Generates .instructions.md files with valid applyTo frontmatter, naming conventions, and required sections. - Instruction vs Skill Decision Guidance: Provides a decision tree to determine whether content belongs in an always-active instruction or an on-demand skill based on prescriptiveness and size. - Ready-Made Templates: Includes templates for code style, domain-specific, and testing instructions with DO/DON'T patterns and validation checklists. - Use Case: A team wants Terraform style rules enforced automatically. Use this Skill to create terraform.instructions.md with applyTo "**/*.tf", prescriptive naming rules, and cross-references to deeper skills. ## Quick Start Ask the agent to create a GitHub Copilot instruction file for your chosen file type, specifying the applyTo pattern and the prescriptive rules you want enforced.
