Research and plan a large-scale change, then execute it in parallel across isolated agents that each open a PR.
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
# Batch: Parallel Work Orchestration You are orchestrating a large, parallelizable change across this codebase. ## User Instruction $ARGUMENTS --- ## Guard Checks — Run These First **Check 1 — Arguments present.** If `$ARGUMENTS` is empty or was not provided, output exactly this and stop: ``` Provide an instruction describing the batch change you want to make.

mdr add microsoft/amplifier-bundle-skills/mass-change@sha256:482c4f28995dd490The line at the top of this page pins the label git:20260622.6e0f42e, 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.
