pi-rg-fd0.2.1

pi-rg-fd

Pi coding agent extension that always rewrites the default system prompt's grep and find advice to rg and fd.

Pi 1.4's bash tool line names grep and find, and the default guideline still names find, so models reach for those commands. This package replaces those two exact lines in place. The usual prompt gets shorter, and text that is not one of those Pi 1.4 lines is left as Pi wrote it. You confirm that rg and fd run on your machine.

Install

pi install npm:pi-rg-fd

For one session without saving the install: pi -e npm:pi-rg-fd.

Requires Pi 1.4.x (@earendil-works/pi-coding-agent).

Replaced lines

Verified against the published @earendil-works/pi-coding-agent@1.4.0 sources (dist/core/tools/bash.js and dist/core/system-prompt.js). These are the only default prompt lines that name the grep or find commands. The read, edit, write, and ls tool snippets do not. The optional grep and find tools are separate Pi tools (they already shell out to rg and fd); their lines are left alone.

Bash tool snippet, before:

Execute bash commands (ls, grep, find, etc.)

Default guideline (bash enabled, and the grep/find/ls tools off), before:

Use bash for file operations like ls, rg, find

Those lines are always rewritten to:

Execute bash commands (ls, rg, fd, etc.)
Use bash for file operations like ls, rg, fd

rg and fd are shorter than grep and find. If neither line is present (a custom system prompt, or a future Pi release that rewords them), the hook returns without changing the prompt.

Pi's interactive mode downloads rg and fd when they are missing, into ~/.pi/agent/bin (or $PI_CODING_AGENT_DIR/bin when that variable is set; a leading ~ is expanded). Bash calls see that directory on PATH. The managed files are named rg and fd, plus .exe on Windows.

Debian and Ubuntu's apt package fd-find installs the binary as fdfind. Alias it so the rewritten prompt matches a command on PATH:

alias fd=fdfind

Prompt text only

pi-cli-guard and pi-prefer-rg rewrite or block bash commands when the model runs them. pi-rg-fd edits the system prompt Pi already built. Commands the model still emits run unchanged.

Compatibility

With @earendil-works/pi-coding-agent installed, npm run compat builds Pi's default system prompt from that package and loads this extension through Pi's extension loader. CI runs the same check on Ubuntu and Windows against the latest Pi release, every day and on manual dispatch.

npm install --no-save @earendil-works/pi-coding-agent@latest
npm run compat
