Cross-platform network troubleshooting (Windows, macOS, Linux) via local or remote shell.

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
# Network Operations Diagnose network problems on Windows, macOS, or Linux with a layered ladder that isolates faults to the smallest possible scope, then pattern-match against OS-specific culprits. Designed for the common case: someone reports "internet broken" on a box you can shell into (locally or via SSH). ## The Universal Insight **Bypass-tool succeeds while OS-resolver fails is a smoking gun on every platform.** It means DNS infrastructure is healthy but the operating system's name-resolution path is hooked or misconfigured. The bypass tool differs per OS but the discriminator is identical: | OS | Bypass tool | OS resolver tool | If bypass works but resolver fails | |---|---|---|---| | Windows | `nslookup` | `Resolve-DnsName`, browsers | NRPT, WFP, HOSTS, LSP, local 127.0.0.1:53 proxy | | macOS | `dig @1.1.1.1` | `dscacheutil -q host`, browsers | `/etc/resolver/*`, scutil DNS, profiles, mDNSResponder, kext | | Linux | `dig @1.1.1.1` | `getent hosts`, `resolvectl query` | systemd-resolved, `/etc/resolv.conf`, NetworkManager, dnsmasq, NSS | …

How to install
mdr add 0xdarkmatter/claude-mods/net-ops@sha256:d496b132cadc8cf1The line at the top of this page pins the label git:20260825.caf325f, 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.
