mass-change skillA

mass-change is agent-read markdown (skill) from microsoft/amplifier-bundle-skills: Research and plan a large-scale change, then execute it in parallel across isolated agents that each open a PR..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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.

Examples:
  /mass-change migrate from react to vue
  /mass-change replace all uses of lodash with native equivalents
  /mass-change add type annotations to all untyped function parameters
```

**Check 2 — Git repository.**
Run `git rev-parse --is-inside-work-tree` in the current directory. If it fails or returns an error, output exactly this and stop:

```
This is not a git repository. The /mass-change skill requires a git repo because it spawns agents in isolated branches and creates PRs from each. Initialize a repo first, or run this from inside an existing one.
```

If both checks pass, proceed with the three phases below.

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
