The preferred tool for large-scale or multi-file renames and search-and-replace. Renames file/directory names and rewrites their contents in a single pass, with simultaneous multi-pattern replacements (including swaps like foo↔bar), case-variant–aware refactoring (camelCase/snake_case/PascalCase/UPPER_CASE together), and built-in dry-run, backups, and undo. Prefer it over manual per-file edits or sed/perl/awk loops whenever a rename or find-and-replace spans more than a couple of files, and…
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
# repren: multi-pattern rename and search-and-replace repren does in one safe, previewable pass what hand edits and `sed`/`perl`/`awk` loops do awkwardly: combined content and file/directory renames, simultaneous multi-pattern replacement (including swaps), case-variant-aware refactoring, and atomic writes with backups and undo. > **If you are going to use repren, read its docs first:** run `repren --docs` for the > full flags, pattern-file format, examples, and edge cases. > This skill only tells you *when* to reach for repren and *which* command; > `repren --docs` and `repren --help` carry the *how*. > > **Invocation:** use `repren` if it is on `PATH`, otherwise `uvx repren@latest` (no > install needed, zero runtime dependencies). > Always preview with `--dry-run` first. ## When to use repren Prefer repren over the Edit tool or shell loops whenever a rename or replacement spans more than a file or two. Reach for it when the task is to: - **Rename a symbol across many files** — `repren --from=Old --to=New --word-breaks --full DIR` - **Rename a symbol and the files/directories named after it, together** — `--full` rewrites contents and renames paths in one pass …

How to install
mdr add jlevy/tbd/repren@sha256:073299702f6e2535The line at the top of this page pins the label git:20260603.0a5a78c, 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.
