Find what already does this job, in the repo and outside it, then say whether to reuse, wrap, borrow or build. Use when something new is about to be written and nobody has checked whether the stdlib, a dependency or the platform already covers it. Auto-triggers on: "has this been done", "is there a library for", "should I build this", "prior art", "am I reinventing", "build it from scratch".

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

# Originality

Original does not mean unprecedented; it means *knowing what exists and being
deliberate about differing from it*. The expensive mistake is the fourth in-house
implementation of something the stdlib has had since 2019 — written confidently,
because nobody looked.

This is `library-first` extended past the repo boundary. Ten minutes here routinely
deletes a week.

## 1. Search inward first — the cheapest win

```sh
devil codemap       # where a symbol already lives
devil dupes         # blocks already repeated
devil facts         # what the project already scripts
devil scripts list  # the vetted external script registry
rg -i '<the concept, and its synonyms>'
```

Search **behaviour, not your chosen name**. The existing implementation is called
`normalize`, you were going to call it `sanitize`, and that is why you did not find it.
Try three names.

Check the dependency manifest too. The project very likely already pulls in a date
library, a validator, a fetch wrapper, a retry helper — rung 4 of
`rules/minimalism-ladder.md`.

## 2. Search outward — the ladder, in order

1. **The standard library.** Check it properly. `itertools`, `slices`, `Intl`,
…

How to install

The exact contents, by fingerprint
mdr add univers42/claude-deal-with-the-devil/originality@sha256:6f55a99fa2a5c93d

The line at the top of this page pins the label git:20261017.fcaf2cc, 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.
