about

wrench is a local command-line tool for giving coding agents narrow, typed tools instead of unrestricted access.

built-in providers use the same plugin contract as extensions. a plugin declares its operations, authentication boundary, inputs, outputs, and risk, so an agent can write a small plugin that you can inspect, check, and test before trusting its code.

supported signed-in reads run through explicit connections. changes produce an exact preview and wait for confirmation, while credentials and raw browser access stay out of command results.
