Quick Reference

Claude Code GitHub Copilot Location

SKILL.md SKILL.md .claude/skills/

• .github/skills/

commands/.md prompts/.prompt.md .claude/commands/

• .github/prompts/

agents/.md agents/.md .github/agents/ (shared)

chatmodes/*.chatmode.md .github/chatmodes/

Sync Process

Step 1: Understand Current Setup

Read these files to understand current configuration:

.claude/workflows/orchestration-protocol.md .claude/workflows/primary-workflow.md .github/copilot-instructions.md .github/AGENTS.md CLAUDE.md

Step 2: Research Latest Features

Search web for:

• "GitHub Copilot features setup 2026"

• "GitHub Copilot custom instructions agents skills prompts"

• "GitHub Copilot agent mode workspace context"

See references/copilot-features.md for feature catalog.

Step 3: Identify Sync Opportunities

Compare capabilities and identify gaps:

• Skills missing in one platform

• Inconsistent prompt/instruction behavior

• Agent definitions that differ

Step 4: Implement Changes

For each change:

• Skills: Create in both .claude/skills/ and .github/skills/

• Prompts: Create in both .claude/commands/ and .github/prompts/

• Instructions: Update both CLAUDE.md and .github/copilot-instructions.md

• Agents: Update .github/agents/ (shared by both)

Compatibility Notes

• Copilot reads .claude/skills/ automatically (backward compatibility)

• Both read .github/prompts/*.prompt.md

• Both read .github/agents/*.md

• Both read AGENTS.md in root or .github/

• Both support path-based instruction files via applyTo in frontmatter
