Copilot Review Init

Generate a complete set of GitHub Copilot code review instruction files tailored to a specific repository.

What This Produces

GitHub Copilot code review reads instruction files from a PR's repository to guide its analysis. This skill generates:

1. .github/copilot-instructions.md — Repository-wide review standards applied to every file
2. Multiple .github/instructions/*.instructions.md — Focused micro-files, each scoped to specific file types via applyTo frontmatter

Why Micro-Files

The micro-file architecture is the core design philosophy. Instead of cramming everything into one file:

• Each file stays within Copilot's 4,000-character processing window (content beyond this is silently ignored)
• Language-specific rules never bleed into unrelated files
• Teams can own and iterate on their relevant instruction files independently
• Adding a new concern means adding a new file, not editing a monolith
