pi-nushell

A pi extension that adds a nu tool for executing nushell commands.

The tool follows pi's built-in bash tool behavior:

• runs in the current session working directory;
• streams combined standard output and standard error;
• supports cancellation and optional timeouts;
• reports nonzero exit codes as tool errors;
• limits output to the last 2,000 lines or 50 KB;
• saves complete output to a temporary file when truncation occurs;
• exposes PI_SESSION_ID, PI_SESSION_FILE, PI_PROVIDER, PI_MODEL, and PI_REASONING_LEVEL to the command.

Requirements

• nushell

Install

pi install npm:pi-nushell

For development, load the extension directly:

pi -e ./index.ts

Tool input

{
  "command": "open package.json | get scripts",
  "timeout": 30
}

• command is required and must use nushell syntax.
• timeout is optional and is measured in seconds. There is no default timeout.

This extension uses nushell's command-string mode, meaning it does not load configuration files like config.nu.
