description	Sync shared skills from the SharedSkillsLuke GitHub repo. Checks the repo for changes, pulls the latest, and copies any new or updated skill folders into ~/.claude/skills/. Also pushes any local skill changes (for skills tracked in the repo) back to GitHub. Designed to run daily as a scheduled task to keep Jesse and Luke in sync.

Sync Shared Skills

What This Does

Keeps your local Claude Code skills in sync with the SharedSkillsLuke GitHub repo. This is a two-way sync:

1. Pull: Fetches the latest from GitHub and copies any new/updated shared skills into ~/.claude/skills/
2. Push: If any of the locally-tracked shared skills have been modified, commits and pushes them back to the repo

This enables Jesse and Luke to share skills — either person can update a skill, push it, and the other picks it up automatically.

Steps

Step 1: Pull latest from GitHub

cd /Users/jesseanglen/SharedSkillsLuke
export PATH="/opt/homebrew/bin:$PATH"
git fetch origin
git pull origin main --rebase 2>/dev/null || git pull origin main

Step 2: Identify shared skills

List all skill directories inside /Users/jesseanglen/SharedSkillsLuke/skills/. Each subdirectory is a shared skill.

Step 3: Sync FROM repo TO local skills

For each skill directory found in /Users/jesseanglen/SharedSkillsLuke/skills/:

1. Compare the repo version with ~/.claude/skills/<skill-name>/
2. If the repo version is newer (based on file content diff), copy it to ~/.claude/skills/<skill-name>/
3. If the skill doesn't exist locally yet, copy the entire folder to ~/.claude/skills/
4. Preserve any local files that don't exist in the repo version (don't delete extras)

Use this approach:

# For each skill dir in the repo
for skill_dir in /Users/jesseanglen/SharedSkillsLuke/skills/*/; do
  skill_name=$(basename "$skill_dir")
  # Skip the sync skill itself — it's managed separately
  local_dir="$HOME/.claude/skills/$skill_name"

  if [ ! -d "$local_dir" ]; then
    echo "NEW SKILL: Installing $skill_name"
    cp -R "$skill_dir" "$local_dir"
  else
    # Check if repo version differs from local
    if ! diff -rq "$skill_dir" "$local_dir" > /dev/null 2>&1; then
      echo "UPDATED: Syncing $skill_name"
      cp -R "$skill_dir"* "$local_dir/"
    else
      echo "UP TO DATE: $skill_name"
    fi
  fi
done

Step 4: Sync FROM local skills TO repo (push changes)

For each skill that already exists in the repo's skills/ directory, check if the local version in ~/.claude/skills/ has changes that aren't in the repo yet:

for skill_dir in /Users/jesseanglen/SharedSkillsLuke/skills/*/; do
  skill_name=$(basename "$skill_dir")
  local_dir="$HOME/.claude/skills/$skill_name"

  if [ -d "$local_dir" ]; then
    if ! diff -rq "$local_dir" "$skill_dir" > /dev/null 2>&1; then
      echo "LOCAL CHANGES: Pushing $skill_name back to repo"
      cp -R "$local_dir"/* "$skill_dir/"
    fi
  fi
done

Step 5: Commit and push any changes

cd /Users/jesseanglen/SharedSkillsLuke
git add -A
if ! git diff --cached --quiet; then
  git commit -m "Auto-sync: update shared skills $(date +%Y-%m-%d)"
  git push origin main
  echo "Changes pushed to GitHub"
else
  echo "No changes to push"
fi

Step 6: Report

Print a summary:

• Skills synced (pulled from repo)
• Skills pushed (local changes sent to repo)
• Any errors encountered
• Timestamp of sync

Important

• The repo lives at /Users/jesseanglen/SharedSkillsLuke/
• GitHub repo: lotfb86/SharedSkillsLuke
• This skill itself lives in the repo at skills/sync-shared-skills/
• Never delete a local skill that isn't in the repo — only add/update
• If there's a merge conflict, prefer the newer version (by timestamp) and flag it in the report
• The sync skill should also be installed to ~/.claude/skills/sync-shared-skills/ so it can be invoked manually
