Finds bug fixes that reached some sibling implementations but not the others, like a fix made to one provider adapter, database driver, cache store, or platform port that its siblings still need. Use when the user asks whether a fix was applied everywhere, wants to audit a codebase with parallel implementations, has just fixed a bug in one adapter, is reviewing a change to one of several siblings, or is looking for real bugs to contribute to an open source project.

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

# half-fixed

A bug gets fixed in one sibling implementation. The others keep the bug, because nobody noticed they had the same code. This skill finds those gaps in git history, works out which ones are real, and fixes the real ones with tests.

## The scanner

`scripts/half-fixed.js` in this skill's directory. It needs Node 18 or newer and nothing else. Prefer it to `npx half-fixed`, which runs the same CLI but trusts the `node_modules` and `.npmrc` of the directory it starts in. If you use npx on a repository the user doesn't maintain, start it from outside: `cd "$(mktemp -d)" && npx half-fixed scan /path/to/repo`.

```bash
node <this-skill-dir>/scripts/half-fixed.js scan [repo] --json   # findings
node <this-skill-dir>/scripts/half-fixed.js show <id> [repo]     # one finding in full
node <this-skill-dir>/scripts/half-fixed.js groups [repo]        # the sibling groups it compares
```

Useful flags: `--confidence medium` (or `--all`) for more findings, `--group <text>` to focus on one group, `--rev <rev>` to scan a branch other than HEAD, `--since <date>` for very long histories. Exit code 1 means findings, 0 means none, 2 means an error.

How to install

The exact contents, by fingerprint
mdr add heyzainali/half-fixed/half-fixed@sha256:426e040da95f569f

The line at the top of this page pins the label git:20261014.88702ee, 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.
