Bilateral SYNERGY/UPSTREAM reconciliation across sibling projects. Use when the user wants to sync sibling SYNERGY/UPSTREAM files, compare both sides to surface drift, find reciprocation gaps (entries here but not there, or vice versa), flag stale-aligned rows, detect status drift across sides, surface friction the sibling tracks ABOUT this project (their UPSTREAM-<this-project>.md), or apply a reciprocation batch with --auto-reciprocate. Workflow 3 covers two UPSTREAM pairing modes: shared…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Sibling Sync

Bilateral reconciliation of `SYNERGY-*.md` and `UPSTREAM-*.md` files between
this project and its sibling vp-\* projects. Read-only by default — surfaces
drift, reciprocal gaps, stale-aligned rows, and status drift across sides
without mutating anything. The opt-in `--auto-reciprocate` flag writes
reciprocal entries to the sibling's SYNERGY file via per-entry confirmation.

Companion to `/vendor-sync` (which handles upstream → project drift); this
skill handles peer-to-peer drift between siblings registered in
`.claude/synergy-registry.json`.

## Design Rationale

The bd v1.0.0 Integration Charter
(`gastownhall/beads@5d524cf7:docs/INTEGRATION_CHARTER.md`) explicitly punts
cross-tracker orchestration out of bd's scope: bd will never grow a feature
that routes a cross-project item from project A's tracker to project B's
tracker. `/sibling-sync` is exactly the workflow-automation layer the Charter
defers to external tools — file-based reconciliation between sibling vp-\*
projects, mediated by registries and confirmation prompts rather than
synchronous tracker calls.

This mirrors the rationale already cited by `/synergy-tracker` for keeping
…

How to install

The exact contents, by fingerprint
mdr add voxpelli/claude-beads/sibling-sync@sha256:e4f2bb8f943b3480

The line at the top of this page pins the label git:20260604.119543a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
