Fixed by updating the hook to resolve acton robustly instead of assuming it’s on PATH.

#!/bin/sh
set -e

# Resolve Acton in environments where Git hooks run with a minimal PATH.
ACTON_BIN="${ACTON_BIN:-}"
if [ -z "$ACTON_BIN" ]; then
  if command -v acton >/dev/null 2>&1; then
    ACTON_BIN="$(command -v acton)"
  elif [ -n "${HOME:-}" ] && [ -x "$HOME/.acton/bin/acton" ]; then
    ACTON_BIN="$HOME/.acton/bin/acton"
  elif [ -n "${USERPROFILE:-}" ] && command -v cygpath >/dev/null 2>&1; then
    WIN_HOME="$(cygpath -u "$USERPROFILE" 2>/dev/null || true)"
    if [ -n "$WIN_HOME" ] && [ -x "$WIN_HOME/.acton/bin/acton" ]; then
      ACTON_BIN="$WIN_HOME/.acton/bin/acton"
    fi
  fi
fi

if [ -z "$ACTON_BIN" ]; then
  echo "pre-commit: acton not found; skipping contract checks." >&2
  echo "Install Acton or set ACTON_BIN to enable these checks." >&2
  exit 0
fi

"$ACTON_BIN" check
"$ACTON_BIN" fmt --check

What it now does:

• Uses ACTON_BIN if you set it.
• Else tries acton from PATH.
• Else tries $HOME/.acton/bin/acton.
• Else tries $USERPROFILE (via cygpath) for Git-for-Windows environments.
  If still not found, it prints a warning and skips checks instead of failing the commit.

Thank you for bringing this issue to our attention.
Could you tell us how you installed Acton in WSL and which distribution you used?

I opened vscode in WSL environment and this fixed the issue. I was using vs code with my windows file system not the WSL.
