Make a public GitHub fork private and keep it synced with its upstream parent. Use when the user wants to make a fork private, or to pull/sync newer commits from the upstream parent into their fork.
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
Convert a fork's visibility to private, then keep it current by fetching from the parent. The whole workflow stays effortless on one condition: the fork's default branch is a **clean mirror** of upstream, so every sync is a **fast-forward** — no merge commits, no conflicts. Prerequisite: `gh` authenticated with `repo` scope, plus a local clone of the fork. Examples use `master`; if the repo's default branch is `main`, substitute it (`gh repo view <owner>/<fork> --json defaultBranchRef -q .defaultBranchRef.name`). ## Make a fork private GitHub now converts a fork's visibility in place — historically this was blocked, which is why mirror-clone workarounds still circulate; you don't need them. The change **detaches the repo from the fork network**: afterwards `gh repo view <owner>/<fork> --json isFork,parent` reports `false` / `null`, so GitHub's fork-only sync (`gh repo sync`, the merge-upstream API, the web "Sync fork" button) stops working. Syncing then runs through plain git, below. ``` gh repo edit <owner>/<fork> --visibility private --accept-visibility-change-consequences ``` `--accept-visibility-change-consequences` is required, and the command prints nothing on success. …

How to install
mdr add soulmachine/skills/private-fork-sync@sha256:37597b2daf8cffdcThe line at the top of this page pins the label git:20261012.88cb6a1, 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.
