Claude Code mod
read-only-mode
/readonly on turns the session into look-but-don't-touch: file edits are refused and only read-only shell commands (ls, cat, git status/log/diff, grep...) run. Safe for exploring unfamiliar code or production checkouts.
Install
/plugin marketplace add cloudcruncher/claude-mod-garage

How Claude Code mods work
- A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
- It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
- Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
- Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.

More git & github mods
quiet-tools
operonlab/claude-code-mods
Draws successful tool calls as one dim line in the terminal and hides their output, keeping its key facts (git commit, background, exit code meaning); a call a hook refused is one red line; failed calls stay in full; ctrl+o shows everything; /quiet-tools toggles it.
replay-theater
im-ksc/ks-claude-code-mods
Replay Theater: step through the file edits Claude made in the last turn, one diff at a time.
quicksave
pourya7/claude-code-mods
A save point before compaction: the task's goal, step, branch, links, decisions, rules and next step are saved before /compact and handed back to the model after it, with a pixel-art SAVE POINT band when it is safe to compact.
replay-theater
kevinfactor/claude-kit
After Claude edits files, a Replay button steps through each edit as a before/after diff. No model calls; the last 60 edits are kept across sessions.
proof-decay
ccdwyer/proof-decay
Tracks which test, typecheck, lint and build results are still true after later edits, and stops commit messages that claim checks which are stale
replay-theater
navin0812/claude-mods
Records every Edit/Write in a turn, then steps through them one diff at a time in a pane (/replay).
