blast-radius

Holds risky Bash commands and shows what they would change before they run.

Guard your repo Version 0.2.2

Install

$ claude plugin marketplace add hamzafer/claude-code-mods
$ claude plugin install blast-radius@claude-code-mods

Restart Claude Code after installing. To try it without installing, clone the repo and run claude --plugin-dir mods/blast-radius.

Cancel / Proceed: Refuse the command, or run it as written
timeoutSeconds: How long to wait before it cancels (default 60, 0 waits forever). Change it in /config

Holds rm -r, git push --force and migrations (prisma, supabase, drizzle-kit, rails, alembic).
Lists the files and size an rm would delete. A path with a shell variable other than ~ or $HOME shows "can't preview" instead of a guess.
Lists the remote commits a force push would drop.
No answer in 60 s cancels the command. Claude gets the reason, so an unattended session keeps going. It never runs the command on its own.
With no screen attached (a plain claude -p run), it cancels at once.
One command is held at a time. A second one waits its turn, then gets its own full countdown.
