CRITICAL: pi Code Review

This skill delegates a code review to the pi CLI tool (@earendil-works/pi-coding-agent). pi runs with read-only tools to prevent accidental edits — it analyzes code and returns findings as text.

CRITICAL: The default review target is the uncommitted working tree (git diff HEAD), and pi must NOT be able to explore the whole codebase or run git itself. pi's --tools flag is a hard allowlist — only listed tools are registered (pi's built-in tools are read, grep, find, ls, bash, edit, write; there is no standalone git tool, but bash can run git diff). By default restrict pi to read only so it can inspect files mentioned in the diff but cannot find/grep/ls the repo or run bash/git. Only expand to read,grep,find,ls when an explicit target (--branch, --diff, PR number) or --explore requires it.

Before Execution: Check Installation

command -v pi >/dev/null 2>&1

If not installed, tell the user and stop.
