About Blast Radius
Blast Radius is an Anthropic sample mod that intercepts selected Bash commands and displays their expected impact. It can show affected files for deletion or destructive Git operations, then waits for a decision in an interactive pane. It only covers the command patterns documented by its maintainer.
- Holds matching tool calls until you respond.
- Lists affected files or Git changes for supported commands.
- Uses an above-prompt fallback when a side pane will not fit.
How to install
Open the source documentation to check prerequisites and installation scope. Copy the commands below and run them one line at a time. Replace any example paths with the directory you intend to use.
Terminal
git clone https://github.com/anthropics/claude-code-playground.git
claude plugin marketplace add ./claude-code-playground/claude-code/mods
claude plugin install blast-radius@claude-code-playground-modsRequires Claude Code 2.1.287 or later. After installation, run /reload-plugins in the active session and check /plugin to confirm the mod loaded.
Complete any authentication or settings steps documented by the maintainer, then reload the session and confirm the capability is available. Entries in the same repository may share a parent plugin installation.
Getting started
Keep the local marketplace checkout after installing. Try a disposable project and a documented command pattern. The pane offers Proceed and Cancel; bash, git, find and du must be available.
Before you use it
Review the project instructions and requested tool access, then try a small task. This directory checks sources and setup notes; inclusion is not a code security audit.
