Overview

Sibling Sync is a security-tested data-ai skill for Claude AI that enables bilateral SYNERGY/UPSTREAM reconciliation across sibling projects. It's used to sync sibling SYNERGY/UPSTREAM files, compare both sides to surface drift, find reciprocation gaps, flag stale-aligned rows, detect status drift across sides, and surface friction the sibling tracks about this project. The skill compares both sides without writing by default and is not for logging entries on this side or upstream project drift.

Key features

  • Bilateral SYNERGY/UPSTREAM reconciliation
  • Read-only by default
  • Optional --auto-reciprocate flag
  • Compares SYNERGY-*.md and UPSTREAM-*.md files
  • Handles peer-to-peer drift between sibling vp-* projects

Use cases

Syncing Sibling Projects

Use Sibling Sync to sync sibling SYNERGY/UPSTREAM files and compare both sides to surface drift and reciprocal gaps.

Surface Friction and Drift

Use Sibling Sync to surface friction the sibling tracks about this project and detect status drift across sides.

Auto-Reciprocate

Use the optional --auto-reciprocate flag to write reciprocal entries to the sibling's SYNERGY file via per-entry confirmation.

Pros & Cons

Pros

  • Surfaces drift and reciprocal gaps between sibling projects
  • Flags stale-aligned rows and status drift across sides
  • Surfaces friction the sibling tracks about this project
  • Optional auto-reciprocate feature for writing reciprocal entries

Cons

  • Not for logging entries on this side (use /synergy-tracker workflow 1)
  • Not for upstream project drift (use /vendor-sync)
  • Requires manual confirmation for auto-reciprocate

Q&A

Can Sibling Sync log new synergy entries for the current project?

No, logging entries on this side is handled by the /synergy‑tracker workflow; Sibling Sync only reports findings and optionally writes to the sibling’s SYNERGY file.

Asked by Robert Ainsworth · Jan 10, 2026

When should I use Sibling Sync versus /vendor‑sync?

Use Sibling Sync for peer‑to‑peer drift between sibling projects; use /vendor‑sync for upstream project drift that involves third‑party dependencies.

Asked by Elena Rossi · Dec 13, 2025

What types of files does Sibling Sync compare?

It reconciles the SYNERGY‑*.md and UPSTREAM‑*.md files between sibling vp‑* projects, surfacing drift, gaps, stale rows, and status differences.

Asked by Rina Desai · Oct 18, 2025

Does Sibling Sync modify files automatically?

No, it operates in read‑only mode by default and only writes reciprocal entries when you use the optional --auto‑reciprocate flag, which requires per‑entry confirmation.
