Pi packages can execute code and influence agent behavior. Review the source before installing third-party packages.

A pi extension that expands inline bash commands in user prompts before they are sent to the agent.

This started from the original inline-bash.ts example in earendil-works/pi-mono, with small packaging and safety tweaks.

Write inline commands with !{...}:

What's in !{pwd}?
The current branch is !{git branch --show-current} and status: !{git status --short}
My node version is !{node --version}

The extension runs each command and replaces the !{command} pattern with trimmed stdout or stderr. Each expansion is capped at 50,000 characters.

Whole-line !command syntax is left alone so pi's built-in shell-command behavior still works.

pi install npm:@diegopetrucci/pi-inline-bash

pi install npm:@diegopetrucci/pi-extensions

pi install git:github.com/diegopetrucci/pi-extensions

Then reload pi:

/reload

Hooks the input event.
Inline commands run through bash -c with a 30-second timeout.
Extension-injected follow-up messages are ignored to avoid implicit shell execution from other extensions.
In interactive mode, pi shows a notification summarizing the expanded commands.
Treat prompt text containing !{...} as shell code; only use this extension where prompt authors are trusted.
permission-gate does not intercept these user-prompt expansions because they run before agent tool calls.
