# AI Dev Tools Sync

> [AI & Tools] Synchronize and update Claude Code and GitHub Copilot development tool configurations to work similarly. Use when asked to update Claude Code setup, update Copilot setup, sync AI dev tools, add new skills/prompts/agents across both platforms, or ensure Claude and Copilot configurations are aligned. Covers skills, prompts, agents, instructions, workflows, and chat modes.

> **[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:**

1. **Understand** — Read current configs (CLAUDE.md, copilot-instructions.md, agents, workflows)
2. **Research** — Search for latest features across both platforms
3. **Compare** — Identify gaps in skills, prompts, agents, or instructions
4. **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](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/skills/` and `.github/prompts/`
3. **Instructions**: Update `CLAUDE.md` + `.github/copilot-instructions.md` + `.github/instructions/*.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

**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
