Use before committing, opening a PR, or reporting a task done — when you want ground-truth confirmation there are no conflict markers, live-looking credentials, debug leftovers, untracked TODOs, or oversized files, without spending a model turn re-reading every file yourself.

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

# Deterministic Checks

## Overview

A shell script that scans a repository for five specific, mechanically-detectable problems and reports file:line locations. Zero model cost — it never asks Claude to "be careful" about something a regex can already prove.

**Core principle:** If a check can be regex or `wc -c`, it should never be a paragraph of instructions asking the model to look carefully. Reserve judgment calls for the model; hand mechanical checks to the script.

## What it checks

| Check | Catches | Misses (by design) |
|---|---|---|
| Conflict markers | `<<<<<<<`, `=======`, `>>>>>>>` at line start | Markers inside a fenced code block that's *documenting* conflict markers (a known false-positive class — see below) |
| Live-looking credentials | AWS keys, GitHub tokens, PEM private keys, `sk-`-style API keys | Anything not matching those four shapes — this is not a general secret scanner |
| Debug leftovers | `console.log`/`console.debug`, `debugger;`, `pdb.set_trace()`, `binding.pry` in JS/TS/Python/Go/Ruby files | Debug prints in languages/patterns not listed |

How to install

The exact contents, by fingerprint
mdr add rtur2003/claude-code-promts-skills/deterministic-checks@sha256:71d9b9c803a08596

The line at the top of this page pins the label git:20260922.b9cbd31, 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.
