Skills Overview

Copilot Collections includes 30 reusable skills — knowledge modules that provide specialized domain expertise, structured processes, and quality templates. They encode tested best practices for every phase of the product lifecycle. Skills are stored in .github/skills/ and loaded automatically by agents when their domain applies to the current task.

How Skills Work

Each skill folder contains a SKILL.md file with:

• Domain-specific guidelines — Best practices, checklists, and processes.
• Templates — Example output formats (e.g., plan.example.md, research.example.md).
• Connected skills — References to other skills that complement or support this one.

When an agent starts a task, it checks all available skills and decides which ones to load. Multiple skills can be combined for tasks spanning different domains.

Loading Priority

Skills follow a strict priority hierarchy:

1. Project instructions (*.instructions.md files) — highest priority.
2. Existing codebase patterns — replicate established conventions.
3. Skill guidelines — domain best practices and templates.
4. External documentation — framework docs, OWASP, industry standards.

This ensures consistency: existing patterns are never overridden unless explicitly requested.
