Edit files by citing per-line LINE#HASH anchors through the optional OMD anchored-edit component.
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
Use only when the separately trusted `omd_anchored_edit` component is enabled. Its plugin installation alone does not enable a tool or grant write permission.
Get anchors from the component's `read` tool (optionally `offset`/`limit`) or its `search` tool (ripgrep; `path`, `glob`, `literal`, `ignore_case`, `context`). Each line appears as `LINE#HASH|content`; the hash covers the line number and content. Never invent or guess an anchor.
Call `edit` with `files: [{path, edits}]`. Each edit is one of:
- `replace` with `anchor`, optional `end` (inclusive last line) and `lines`
- `delete` with `anchor` and optional `end`
- `insert_before` / `insert_after` with `anchor` and `lines` (the anchor line stays)
- `append` / `prepend` with `lines`
Only the cited lines are checked, so changes elsewhere do not block an edit. All edits in one call apply atomically or not at all; ranges must not overlap. On success the result lists `+LINE#HASH|content` for every changed line: use those anchors for the next edit of that file instead of rereading. CRLF, final-newline state and bytes outside the edited lines are preserved.

How to install
mdr add dzkchen/oh-my-diff/omd-anchored-edit@sha256:9a1fcb82de5db7bcThe line at the top of this page pins the label git:20261008.8e2865a, 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.
