[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ask user whether to skip.

Quick Summary

Goal: Synchronize Claude Code and GitHub Copilot configurations to maintain feature parity across both AI dev tools.

Workflow:

• Understand — Read current configs (CLAUDE.md, copilot-instructions.md, agents, workflows)

• Research — Search for latest features across both platforms

• Compare — Identify gaps in skills, prompts, agents, or instructions

• Sync — Implement changes in both platforms maintaining compatibility

Key Rules:

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

• Both platforms read .github/prompts/.prompt.md and .github/agents/.md

• Always update both CLAUDE.md and .github/copilot-instructions.md

• .github/instructions/*.instructions.md for instruction changes

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

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/

SKILL.md prompts/*.prompt.md .claude/skills/

• .github/prompts/

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

workflows/*.md

.claude/workflows/

CLAUDE.md copilot + instructions/ Root + .github/

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/instructions/*.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/skills/ and .github/prompts/

• Instructions: Update CLAUDE.md

• .github/copilot-instructions.md
• .github/instructions/*.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

IMPORTANT Task Planning Notes (MUST FOLLOW)

• Always plan and break work into many small todo tasks

• Always add a final review todo task to verify work quality and identify fixes/enhancements
