How to execute a LARGE MECHANICAL change across any codebase with LEVERAGE instead of an agent-grind or hand-edits — a cross-cutting migration, refactor, rename, dialect/framework/DB port, library adoption, or bulk transform. The map→transform→gate pattern: a deterministic transform driven by a source-of-truth map, proven by a differential-equivalence gate. Use when the work is "migrate all X to Y", "rename Z everywhere", "port to a new DB/dialect/framework", "adopt a library across N files…
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
# Large-scale mechanical change — leverage, not grind A change touching dozens-to-thousands of sites is NOT N problems. It is a small number of repeated PATTERNS. Reaching for "fan out 1000 agents to edit each site", "hand-edit every file", or "sed the repo" is the paper bag. Reduce the work to **MAP → TRANSFORM → GATE** instead. ## The core pattern 1. **MAP** — the source of truth that already exists or can be **deterministically extracted**: an inventory of the affected sites, an ownership/registry table, a call graph, a schema. Build it with an **AST tool** (ts-morph, libcst, jscodeshift, tree-sitter, Roslyn…) or **semgrep** — never a regex string-grep (quote/escaping/comment blind spots), and never "an agent grepped and *thinks* it found them all." An exhaustive, reproducible map is the foundation; an approximate one ships a partial migration. …

How to install
mdr add mikeparcewski/wicked-garden/wicked-garden-engineering-large-scale-migration@sha256:735784fb4e9cc1c9The line at the top of this page pins the label git:20260914.0605b65, 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.
