Copilot Sync Skill

Synchronize GitHub Copilot configuration files from the base template to existing codebases.

Triggers

Activate this skill when user mentions:

"sync copilot", "copilot sync"
"update copilot files", "update copilot configuration"
"sync copilot config", "sync configuration"
"bring project up to date with copilot"
"#copilot-sync"

Description

The Copilot Sync skill synchronizes all Copilot-related files from the

github-copilot-base

template to an existing codebase:

Agents - All
```
.github/agents/*.md
```
files
Prompts - All
```
.github/prompts/*.prompt.md
```
files
Skills - All
```
.github/skills/*/
```
directories
Instructions -
```
.github/copilot-instructions.md
```
PRP Framework -
```
PRPs/
```
templates
Supporting Docs - Background workflow, style guides

Key Features:

💾 Automatic backups before overwriting
👁️ Dry-run mode for previewing changes
✅ Validation of target repository
📊 Detailed sync statistics

Workflow Steps

1. Gather Information

Collect the following using

ask_user

Question	Purpose	Validation
Target path	Codebase to sync to	Must exist, must be Git repo
Dry run?	Preview changes first	Yes/No

2. Validate Target

# Check path exists
if (-not (Test-Path $TargetPath -PathType Container)) {
    Write-Error "Path does not exist"
}

# Check it's a Git repository
if (-not (Test-Path (Join-Path $TargetPath ".git"))) {
    Write-Error "Not a Git repository"
}

3. Execute Sync

Dry Run (Preview):

$TemplateRepo = "E:\Repos\HouseGarofalo\github-copilot-base"
& "$TemplateRepo\scripts\sync-copilot.ps1" -TargetPath $TargetPath -DryRun

Apply Changes:

$TemplateRepo = "E:\Repos\HouseGarofalo\github-copilot-base"
& "$TemplateRepo\scripts\sync-copilot.ps1" -TargetPath $TargetPath

Force (No Prompts):

& "$TemplateRepo\scripts\sync-copilot.ps1" -TargetPath $TargetPath -Force

4. Post-Sync Guidance

After sync, guide user to:

Review copilot-instructions.md - Add project-specific context
Check backups - In
```
.copilot-backup/
```
folder

Commit changes:

git add .github PRPs docs
git commit -m "chore: sync Copilot configuration from github-copilot-base"

5. Output Summary

Backup & Recovery

Backup Location:

<target>\.copilot-backup\

Error Handling

Error	Resolution
Path doesn't exist	Provide valid path
Not a Git repo	Initialize with `git init`
Permission denied	Check write access
Backup failed	Use `-NoBackup` or check disk space

Prerequisites
