When to choose it
Learning how a mod can hold a tool call and show a decision pane.
Choose it if: You want to study a sample that holds matching tool calls and presents Proceed or Cancel decisions.
Look elsewhere if: You need a sandbox or comprehensive command protection; scripts, aliases and wrappers can bypass its matching.
What the source describes
- Recognizes selected deletion, Git and migration commands
- Shows affected paths or changes
- Proceed and Cancel controls with a narrow-terminal fallback
Requirements
- Claude Code v2.1.287 or later
- bash, git, find and du
- Project migration tools for migration reports
Review, then try in one session
These commands download the sample and then load its code. Read the source before running the final line. Validation is an inspection aid, not a security guarantee.

Read the matcher limitations first. Explore its behavior only in a disposable repository.
Installation and loading troubleshootingLimitations & considerations
- Does not parse the full shell language; scripts, aliases and wrappers can bypass its matching
- It is an unsupported demonstration, not a sandbox or a safety guarantee
Mods can act with your user privileges, including file access, processes and network requests. ClaudeStack has not run this sample. Check the official trust guidance before loading it.
