Use when writing or reviewing error handling, floating-point math, concurrent code, remote calls, singletons/globals, hot-path data structures, or high-volume log statements.
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
# Error and Correctness Traps ## Overview Common bugs grouped by domain: floats that won't compare equal, retries that hammer a downed service, singletons that wreck testability, and others. **When you write code in one of these domains, stop and run the matching checks before you commit.** This is a **rigid** skill. Jump to the sub-section that matches what you're writing and run that sub-section's checks. These checks matter most when code will reach real users in production. In MVPs, prototypes, internal dev tools, and one-off scripts where the architecture is still in flux, prefer the simplest thing that works. ## When to invoke Invoke when you're about to: - Add or change error-handling around a call that can fail - Compare, sum, or accumulate floating-point numbers - Write concurrent, parallel, or threaded code, or share mutable state between threads - Call a remote process, web service, database, or another machine - Introduce a singleton or any globally-shared mutable state - Choose a data structure or algorithm on a path that runs often or on large inputs - Add or change log statements that may fire at high volume …

How to install
mdr add oribarilan/97/correctness-traps@sha256:3aba0e077c486b5cThe line at the top of this page pins the label git:20260510.17c5ab8, 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.
