FAQPage Schema

How do I create and maintain VS Code agent customization files?▼

You create VS Code agent customization files by editing .instructions.md or SKILL.md to define preferences, configure applyTo patterns, and validate YAML frontmatter structure for predictable agent loading and reliable behavior across projects.

Why does my VS Code agent ignore my custom instructions?▼

Your VS Code agent ignores custom instructions when YAML frontmatter is misconfigured. You can troubleshoot ignored agents by validating the frontmatter structure, checking applyTo patterns, and ensuring tooling aligns with project conventions for correct progressive loading.

How do I validate YAML frontmatter in copilot-instructions.md files?▼

You validate YAML frontmatter in copilot-instructions.md files by running a consistency check across agent customization files to enforce structural correctness, troubleshoot misconfigurations, and ensure predictable loading of coding preferences and tool restrictions.

Can I configure applyTo patterns and tool restrictions for VS Code agents?▼

Yes, you configure applyTo patterns and tool restrictions for VS Code agents by defining settings within the YAML frontmatter of agent customization files, aligning automated tooling with specific project conventions and workflows.

What is the best way to package domain knowledge for repeatable agent workflows?▼

The best way to package domain knowledge for repeatable agent workflows is to create agent customization files like AGENTS.md or .prompt.md, validating the YAML frontmatter to ensure progressive loading and reliable behavior across project teams.
