Use when asked to update, upgrade, refresh, reinstall, or migrate Megapowers, check for a newer release, or repair stale installed plugin state.
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
# Upgrading Megapowers Before any write, inventory visible registrations: enabled state and version, exposed scope, marketplace name and source, pin or ref, local edits, duplicates, caches, and active sessions. Read the stable release and changelog without writes. Stop on ambiguous provenance, managed-source edits, or conflicting installations. If already current, report a verified no-op. Preserve enabled state, source or channel, scope, pin, and local edits. A floating Git marketplace follows its latest stable release; a pinned or local checkout changes only when explicitly approved. Keep one installation channel per harness and exclude unrelated cleanup. Follow the [channel reference](references/channels.md) for the inventory commands, the release-commit to marketplace-head comparison, and the refresh and registration commands. Never install unreleased branch state as a stable upgrade. A registration that tracks the default branch is a channel defect: report it and propose re-registering at `release` as a separately approved write. Request one exact approval covering target harnesses, enabled state, source, …

How to install
mdr add lawzava/megapowers/upgrading-megapowers@sha256:e784b57e1f7da90dThe line at the top of this page pins the label git:20260925.d238822, 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.
