The homebrew cask links only `coderabbit`. PostHog's reviewing-with-coderabbit skill calls `cr`, so link that name into ~/.local/bin, which zshenv puts on PATH in every shell context. Claude-Session: https://claude.ai/code/session_011M4DkeAnSqEYd7RDxiaGFQ

reviewing-with-coderabbitskill runs a CodeRabbit pass over the branch beforegh pr create, but the binary only existed inside the posthog flox env at~/.config/posthog/tools/coderabbit/<version>/coderabbit. Agents running outside that env reported the CLI as missing and opened PRs without a local review pass.coderabbithomebrew cask.~/.local/bin/cr. The cask links onlycoderabbit, and the skill callscr.~/.local/binis the right home for the link:zshenv.symlinkputs it on PATH in every shell context, while~/.dotfiles/binis added inzshrc, which the non-interactivezsh -lcthat coding agents shell out through never sources.The link points at
$(brew --prefix)/bin/coderabbitrather than whatevercoderabbitPATH resolves to. Run from an activated posthog shell the latter is the worktree venv copy, which would leave a dangling link once that worktree is removed.Two versions coexist after this. Flox pins 0.7.6 inside the posthog env and that copy wins there; brew tracks latest, currently 0.7.8, everywhere else.
