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 problem are you solving?
│
├─ Storing UI state that triggers re-renders
│ ├─ Simple value (string, number, boolean)
│ │ └─ useState
│ ├─ Complex state with multiple sub-values and logic
│ │ └─ useReducer (actions + reducer = predictable transitions)
│ └─ Derived from existing state
│ └─ Calculate inline or useMemo — not useState
│
├─ Referencing a value WITHOUT triggering re-render
│ ├─ DOM element reference
│ │ └─ useRef<HTMLElement>(null) + ref={ref}
│ └─ Mutable value (timer ID, previous value, counter)
│ └─ useRef (mutate ref.current directly)
│
├─ Running a side effect
│ ├─ After every render (or specific deps)
│ │ ├─ Needs cleanup (subscription, timer, abort)
│ │ │ └─ useEffect with return cleanup function
│ │ └─ No cleanup (logging, analytics)
│ │ └─ useEffect with empty or dep array
│ ├─ Before browser paint (DOM mutation, animation)
│ │ └─ useLayoutEffect

How to install
mdr add 0xdarkmatter/claude-mods/react-ops@sha256:ea01c06ded686eb9The line at the top of this page pins the label git:20260831.7a7c8a9, 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.
