Selective Copy — Clean Branch Creation

Create a clean git branch from feature work, excluding specific paths. Platform agnostic.

Works with or without aoc CLI. Uses standard git commands.

Purpose

Create a new branch containing feature work while excluding agent/workflow files for clean PRs.

CRITICAL: No Assumptions

NEVER assume. NEVER guess. ALWAYS ask.

Before creating ANY clean branch, confirm with user:

If ANY of these are ambiguous:

1. Stop
2. Ask ONE question at a time
3. Wait for explicit confirmation
4. Only proceed when ALL inputs are confirmed

NEVER:

• Guess the base branch
• Assume exclusions without asking
• Create a branch without showing the user the exact name first
• Proceed if source branch is unclear

Prerequisites

MANDATORY: File Audit Trail

The file-created.log MUST exist before proceeding. This ensures we know which files to exclude.

If .agent/log/created-files.log does not exist:

1. Generate it from git history (see Generation Procedure below)
2. Present to user for validation
3. Only proceed after user confirms the list

This prevents accidental inclusion of agent-ops files in the clean branch.

Invocation

User says something like:

• "Create a clean branch for PR"
• "Make a branch without .agent and .github changes"
• "Prepare my feature for code review"

Arguments

Workflow

1. Gather Requirements

If not provided, ask:

1. Source branch (default: current)
2. New branch name (default: {current}-clean)
3. Base branch — try auto-detect first:

# PowerShell: Find merge-base with main or develop
$mainBase = git merge-base HEAD main 2>$null
$devBase = git merge-base HEAD develop 2>$null

if ($mainBase) { $baseBranch = "main" }
elseif ($devBase) { $baseBranch = "develop" }
else { 
    # Ask user
    Write-Host "Could not auto-detect base branch. Which branch was this feature branched from?"
}

# Bash: Find merge-base
main_base=$(git merge-base HEAD main 2>/dev/null)
dev_base=$(git merge-base HEAD develop 2>/dev/null)

if [ -n "$main_base" ]; then
    base_branch="main"
elif [ -n "$dev_base" ]; then
    base_branch="develop"
else
    echo "Could not auto-detect base branch. Which branch was this feature branched from?"
fi

1. Exclusions — if not specified, prompt:

Would you like to exclude agent-ops files? This includes:
- `.agent/` directory
- `.github/skills/`, `.github/prompts/`, `.github/agents/`

Additionally, agent-ops created these files outside .agent/:
{list from .agent/log/created-files.log}

[1] Exclude all agent-ops files (recommended)
[2] Exclude only .agent/ and .github/
[3] Let me specify custom paths
[4] Don't exclude anything

2. Check and Generate Audit Trail (MANDATORY)

Before proceeding, verify .agent/log/created-files.log exists.

# PowerShell
$logPath = ".agent/log/created-files.log"
if (-not (Test-Path $logPath)) {
    Write-Host "⚠️  File audit trail not found: $logPath" -ForegroundColor Yellow
    Write-Host "Generating from git history..." -ForegroundColor Cyan
    # Proceed to generation
} else {
    Write-Host "✓ Audit trail found: $logPath" -ForegroundColor Green
    # Skip to step 3
}

# Bash
log_path=".agent/log/created-files.log"
if [ ! -f "$log_path" ]; then
    echo "⚠️  File audit trail not found: $log_path"
    echo "Generating from git history..."
    # Proceed to generation
else
    echo "✓ Audit trail found: $log_path"
    # Skip to step 3
fi

If log is missing, generate it:

Generation Procedure

1. Find the branch point (where feature diverged from base):

# PowerShell
$baseBranch = "develop"  # or auto-detected
$branchPoint = git merge-base HEAD $baseBranch
Write-Host "Branch point: $branchPoint"

# Bash
base_branch="develop"
branch_point=$(git merge-base HEAD "$base_branch")
echo "Branch point: $branch_point"

1. List files added since branch point (excluding .agent/ and .github/):

# PowerShell
$addedFiles = git diff --name-status --diff-filter=A $branchPoint HEAD |
    ForEach-Object { ($_ -split "\t")[1] } |
    Where-Object { 
        $_ -notmatch "^\.agent/" -and 
        $_ -notmatch "^\.github/skills/" -and 
        $_ -notmatch "^\.github/prompts/" -and 
        $_ -notmatch "^\.github/agents/"
    }

Write-Host "`nFiles added since branch point:" -ForegroundColor Cyan
$addedFiles | ForEach-Object { Write-Host "  CREATE $_" }
Write-Host "`nTotal: $($addedFiles.Count) files"

# Bash
added_files=$(git diff --name-status --diff-filter=A "$branch_point" HEAD | 
    cut -f2 | 
    grep -v "^\.agent/" | 
    grep -v "^\.github/skills/" | 
    grep -v "^\.github/prompts/" | 
    grep -v "^\.github/agents/")

echo ""
echo "Files added since branch point:"
echo "$added_files" | while read -r file; do
    [ -n "$file" ] && echo "  CREATE $file"
done
echo ""
echo "Total: $(echo "$added_files" | grep -c .)"

1. Present to user for validation (MANDATORY):

📋 Generated file list from git history:

  CREATE src/utils/helper.py
  CREATE tests/test_helper.py
  CREATE docs/PLANNING.md

Total: 3 files

⚠️  Please review this list carefully.

These files will be EXCLUDED from the clean branch.
Missing files may leak into PR. Extra files may be wrongly excluded.

Options:
[1] Approve and continue
[2] Edit list (will open in editor)
[3] Abort

1. Save after user approval:

# PowerShell (only after user confirms)
$logDir = ".agent/log"
if (-not (Test-Path $logDir)) {
    New-Item -ItemType Directory -Path $logDir -Force | Out-Null
}

$timestamp = Get-Date -Format "yyyy-MM-ddTHH:mm:ssZ"

# Write header
@"
# Agent-Ops File Creation Audit Trail
# Generated from git history on $timestamp
# Branch point: $branchPoint (from $baseBranch)
# User validated: YES
# --- Log entries below this line ---
"@ | Out-File -FilePath $logPath -Encoding utf8

# Write entries
foreach ($file in $addedFiles) {
    Add-Content -Path $logPath -Value "$timestamp CREATE $file"
}

Write-Host "✓ Audit trail saved: $logPath" -ForegroundColor Green

# Bash (only after user confirms)
log_dir=".agent/log"
mkdir -p "$log_dir"

timestamp=$(date -u +%Y-%m-%dT%H:%M:%SZ)

# Write header
cat > "$log_path" << EOF
# Agent-Ops File Creation Audit Trail
# Generated from git history on $timestamp
# Branch point: $branch_point (from $base_branch)
# User validated: YES
# --- Log entries below this line ---
EOF

# Write entries
echo "$added_files" | while read -r file; do
    [ -n "$file" ] && echo "$timestamp CREATE $file" >> "$log_path"
done

echo "✓ Audit trail saved: $log_path"

3. Read Audit Trail

Check .agent/log/created-files.log for files created outside .agent/:

# PowerShell
$logPath = ".agent/log/created-files.log"
$createdFiles = Get-Content $logPath | 
    Where-Object { $_ -match "^\d{4}-\d{2}-\d{2}" } |
    ForEach-Object { 
        $parts = $_ -split " ", 3
        [PSCustomObject]@{
            Timestamp = $parts[0]
            Action = $parts[1]
            Path = $parts[2]
        }
    } |
    Where-Object { $_.Action -eq "CREATE" } |
    Select-Object -ExpandProperty Path

Write-Host "Files created by agent-ops:"
$createdFiles | ForEach-Object { Write-Host "  - $_" }

# Bash
echo "Files created by agent-ops:"
grep "^[0-9]" .agent/log/created-files.log | 
    awk '$2 == "CREATE" { print "  - " $3 }'

4. Execute (Git-Based)

Step 1: Create worktree with new branch

# PowerShell
$sourceBranch = git branch --show-current
$newBranch = "$sourceBranch-clean"
$worktreePath = "../$newBranch"

git worktree add -b $newBranch $worktreePath HEAD
Set-Location $worktreePath

# Bash
source_branch=$(git branch --show-current)
new_branch="${source_branch}-clean"
worktree_path="../${new_branch}"

git worktree add -b "$new_branch" "$worktree_path" HEAD
cd "$worktree_path"

Step 2: Restore excluded directories from base branch

# PowerShell
$baseBranch = "develop"  # or detected/user-provided
$excludeDirs = @(".github", ".agent")

foreach ($dir in $excludeDirs) {
    git checkout $baseBranch -- $dir 2>$null
    if ($LASTEXITCODE -eq 0) {
        Write-Host "Restored $dir from $baseBranch"
    } else {
        Write-Host "$dir doesn't exist in $baseBranch (new directory)"
    }
}

# Bash
base_branch="develop"
exclude_dirs=(".github" ".agent")

for dir in "${exclude_dirs[@]}"; do
    if git checkout "$base_branch" -- "$dir" 2>/dev/null; then
        echo "Restored $dir from $base_branch"
    else
        echo "$dir doesn't exist in $base_branch (new directory)"
    fi
done

Step 3: Remove NEW files that don't exist in base

For files logged in audit trail that are new (not in base branch):

# PowerShell
foreach ($file in $createdFiles) {
    # Check if file exists in base branch
    $existsInBase = git ls-tree -r $baseBranch --name-only | Where-Object { $_ -eq $file }
    
    if (-not $existsInBase) {
        # File is new, remove from git tracking
        git rm --cached $file 2>$null
        Write-Host "Removed new file from tracking: $file"
    } else {
        # File exists in base, restore it
        git checkout $baseBranch -- $file 2>$null
        Write-Host "Restored $file from $baseBranch"
    }
}

# Bash
for file in "${created_files[@]}"; do
    if git ls-tree -r "$base_branch" --name-only | grep -q "^${file}$"; then
        # File exists in base, restore it
        git checkout "$base_branch" -- "$file" 2>/dev/null
        echo "Restored $file from $base_branch"
    else
        # File is new, remove from git tracking
        git rm --cached "$file" 2>/dev/null
        echo "Removed new file from tracking: $file"
    fi
done

Step 4: Commit the exclusions

# PowerShell
git add -A
git commit -m "chore: prepare clean branch for PR (exclude agent-ops files)"

# Bash
git add -A
git commit -m "chore: prepare clean branch for PR (exclude agent-ops files)"

Step 5: Create Exclusion Log

Create a log file for selective-merge to use later:

# PowerShell
$timestamp = Get-Date -Format "yyyy-MM-dd-HHmmss"
$logFile = ".agent/log/selective-copy-$newBranch-$timestamp.log"
$cleanBranchHash = git rev-parse HEAD
$sourceBranchHash = git rev-parse $sourceBranch

# Create log directory if needed
New-Item -ItemType Directory -Path ".agent/log" -Force | Out-Null

# Write log header
@"
# Selective Copy Exclusion Log
# Generated: $(Get-Date -Format "yyyy-MM-ddTHH:mm:ssK")
# Source Branch: $sourceBranch ($sourceBranchHash)
# Clean Branch: $newBranch ($cleanBranchHash)
# Base Branch: $baseBranch
# Excluded Paths: $($excludeDirs -join ", ")

# Format: {ACTION} {path}
# RESTORE = restored from base branch
# REMOVE = removed from tracking (new file not in base)

"@ | Out-File -FilePath $logFile -Encoding utf8

# Log each excluded directory
foreach ($dir in $excludeDirs) {
    Add-Content -Path $logFile -Value "RESTORE $dir"
}

# Log removed files from audit trail
foreach ($file in $createdFiles) {
    $existsInBase = git ls-tree -r $baseBranch --name-only | Where-Object { $_ -eq $file }
    if (-not $existsInBase) {
        Add-Content -Path $logFile -Value "REMOVE $file"
    } else {
        Add-Content -Path $logFile -Value "RESTORE $file"
    }
}

Write-Host "Exclusion log created: $logFile"

# Bash
timestamp=$(date +"%Y-%m-%d-%H%M%S")
log_file=".agent/log/selective-copy-${new_branch}-${timestamp}.log"
clean_branch_hash=$(git rev-parse HEAD)
source_branch_hash=$(git rev-parse "$source_branch")

# Create log directory if needed
mkdir -p ".agent/log"

# Write log header
cat > "$log_file" << EOF
# Selective Copy Exclusion Log
# Generated: $(date -Iseconds)
# Source Branch: $source_branch ($source_branch_hash)
# Clean Branch: $new_branch ($clean_branch_hash)
# Base Branch: $base_branch
# Excluded Paths: ${exclude_dirs[*]}

# Format: {ACTION} {path}
# RESTORE = restored from base branch
# REMOVE = removed from tracking (new file not in base)

EOF

# Log each excluded directory
for dir in "${exclude_dirs[@]}"; do
    echo "RESTORE $dir" >> "$log_file"
done

# Log removed files from audit trail
for file in "${created_files[@]}"; do
    if git ls-tree -r "$base_branch" --name-only | grep -q "^${file}$"; then
        echo "RESTORE $file" >> "$log_file"
    else
        echo "REMOVE $file" >> "$log_file"
    fi
done

echo "Exclusion log created: $log_file"

5. Verify

# PowerShell
Write-Host "`n=== Verification ===" -ForegroundColor Cyan

# Check status
git status

# Compare with base branch
Write-Host "`nChanges compared to ${baseBranch}:"
git diff $baseBranch --stat

# Verify excluded paths match base
Write-Host "`nVerifying exclusions:"
foreach ($dir in $excludeDirs) {
    $diff = git diff $baseBranch -- $dir
    if ([string]::IsNullOrEmpty($diff)) {
        Write-Host "  $dir matches $baseBranch ✓" -ForegroundColor Green
    } else {
        Write-Host "  $dir has differences from $baseBranch" -ForegroundColor Yellow
    }
}

# Bash
echo ""
echo "=== Verification ==="

# Check status
git status

# Compare with base branch
echo ""
echo "Changes compared to ${base_branch}:"
git diff "$base_branch" --stat

# Verify excluded paths match base
echo ""
echo "Verifying exclusions:"
for dir in "${exclude_dirs[@]}"; do
    if [ -z "$(git diff "$base_branch" -- "$dir")" ]; then
        echo "  $dir matches $base_branch ✓"
    else
        echo "  $dir has differences from $base_branch"
    fi
done

6. Validate Results (MANDATORY)

After creating the clean branch, validate using created-files.log as source of truth:

# PowerShell - Validation Script
