AI Dev Tools Sync

Synchronize Claude Code and GitHub Copilot configurations to maintain feature parity.

When to Use

Activate this skill when:

• User asks to update Claude Code or Copilot setup
• User wants to add/modify skills, prompts, agents, or instructions
• User wants both tools to work similarly
• User asks about AI dev tool configuration

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)
workflows/*.md	-	.claude/workflows/
CLAUDE.md	copilot-instructions.md	Root + .github/
-	instructions/*.md	.github/instructions/ (applyTo patterns)
-	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:

1. Skills: Create in both .claude/skills/ and .github/skills/
2. Prompts: Create in both .claude/commands/ and .github/prompts/
3. Instructions: Update both CLAUDE.md and .github/copilot-instructions.md
4. 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
