Sync - Repository Synchronization

When this skill is invoked, IMMEDIATELY output the banner below before doing anything else. Pick ONE tagline at random — vary your choice each time. CRITICAL: Reproduce the banner EXACTLY character-for-character. The first line of the art has 4 leading spaces — you MUST preserve them.

Output Formatting

After the banner, display parsed input:

┌─ Input ────────────────────────────────────────
│  {Field}:  {value}
│  Flags:    {parsed flags or "none"}
└────────────────────────────────────────────────

Pre-flight results:

── Pre-flight ───────────────────────────────────
  ✅ {dep}           {version or "found"}
  ⚠️ {dep}           not found → {fallback detail}
  ❌ {dep}           missing → stopping
──────────────────────────────────────────────────

Stage/phase headers: ━━ {N} · {Name} ━━━━━━━━━━━━━━━━━━━━━━━━━

Status icons: ✅ done · ❌ failed · ⚠️ degraded · ⏳ working · ⏭️ skipped

---

Synchronize local repository with the remote default branch using a deterministic bash script — no LLM subagent needed since all steps are pure git commands.

Flags

Parse optional flags from the request:

• --no-stash: Don't auto-stash uncommitted changes
• --no-cleanup: Don't delete stale local branches
• --no-rebase: Use merge instead of rebase when on a feature branch

---

Pre-flight

Before starting, check all dependencies in this table:

| Dependency | Type | Check | Required | Resolution | Detail | |-----------|------|-------|----------|------------|--------| | git | cli | git --version | yes | stop | Install from https://git-scm.com |

For each row, in order:

1. Run the Check command (for cli/npm) or test file existence (for agent/skill)
2. If found: continue silently
3. If missing: apply Resolution strategy
   • stop: notify user with Detail, halt execution
   • url: notify user with Detail (install link), halt execution
   • install: notify user, run the command in Detail, continue if successful
   • ask: notify user, offer to run command in Detail, continue either way (or halt if required)
   • fallback: notify user with Detail, continue with degraded behavior
4. After all checks: summarize what's available and what's degraded

---

Pre-flight Detection

Before launching the subagent, detect the remote and default branch:

REMOTE=$(git remote | head -1)   # usually "origin"
DEFAULT_BRANCH=$(git symbolic-ref refs/remotes/$REMOTE/HEAD 2>/dev/null | sed 's|.*/||')

Fallback chain if symbolic-ref fails:

1. Check git show-ref --verify refs/heads/main → use main
2. Check git show-ref --verify refs/heads/master → use master
3. If neither exists, report error and stop

Pass {REMOTE} and {DEFAULT_BRANCH} into the subagent prompt.

---

Execution

Run the sync script directly — no LLM subagent needed since all steps are deterministic git commands:

# Resolve skill root (plugin install or direct install)
for SKILL_ROOT in \
  "${CLAUDE_PLUGIN_ROOT:-}" \
  "$HOME/.claude/plugins/marketplaces/slamb2k" \
  "$(dirname "$(readlink -f "$0")")/.."
do
  [ -f "$SKILL_ROOT/skills/sync/scripts/sync.sh" ] && break
done

bash "$SKILL_ROOT/skills/sync/scripts/sync.sh" \
  "{REMOTE}" "{DEFAULT_BRANCH}" {FLAGS}

Parse the output between SYNC_REPORT_BEGIN and SYNC_REPORT_END markers. Extract key=value pairs for the report fields: status, remote, default_branch, main_updated_to, current_branch, stash, rebase, branches_cleaned, errors.

Exit codes: 0=success, 1=fatal error, 2=partial success (conflict warnings).

---

Report to User

Parse the subagent's SYNC_REPORT and present a clean summary:

┌─ Sync · Report ────────────────────────────────
│
│  ✅ Sync complete
│
│  🌿 Main:     {commit} — {message}
│  🔀 Branch:   {current_branch}
│  📦 Stash:    {restored|none|conflict}
│  🧹 Cleaned:  {branches or "none"}
│
└─────────────────────────────────────────────────

If errors occurred:

│  ❌ {error description}
│     {suggested resolution}
