Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
bulkhead
PreToolUse hooks that keep several Claude Code sessions running on one machine from colliding. Blocks kills by program name (pkill node, taskkill /IM node.exe) and kills that reach another session's processes, dev servers on a port another session uses, heavy commands when RAM is low, git checkout, stash, add -A and commit -a in a tree another session works in, and whole-disk scans such as du -sh ~. Stops servers left by finished sessions. bulkhead scan replays the shell commands in your past transcripts against the guards, read-only, with nothing sent anywhere. Blocks return the reason and an alternative command to the agent; only the user can allow a blocked command, and a repository's own config can only make the guards stricter. It parses command strings and is not a sandbox. Node only, no dependencies.
herdr-toolkit
One skill for running Claude Code on Herdr, the terminal agent multiplexer. spawn-session starts a named, detached Claude Code Remote Control session for any project directory in its own Herdr pane, so it appears in the Claude mobile app, and confirms on the pane screen that each prompt landed.
