Clean up .direnv directories that act as Nix store GC roots, freeing disk space. Use when you want to reclaim Nix store space by removing stale direnv flake caches (e.g., "clean up direnv roots", "free nix store space", "remove direnv caches").

Run a code review using Codex CLI. Use when the user wants a code review of uncommitted changes, a specific commit, or changes against a base branch.
Guides execute-inspect-adjust development and t-wada Red-Green-Refactor TDD. Use for exploratory implementation or when stable behaviour needs an executable test-first contract.
Prevents and handles GitHub API rate limits with gh-nix. Use when Nix, flakes, nixpkgs commands, or comma may fetch GitHub-backed inputs.
Manages worktree lifecycle operations through git-wt without replacing an existing linked worktree. Use when creating, switching, listing, renaming, or deleting worktrees.
Runs the full PR workflow — creates a feature branch, commits, pushes, and opens the pull request. Use when the user asks to create or open a PR ("create a PR", "push this up and open a PR").
Resolves missing CLI tools. Use when a command is unavailable, a shell reports command not found, or a tool must be run without installing it globally.

You are a Nix store cleanup assistant. Your task is to find and remove .direnv directories that hold GC roots in the Nix store, then optionally run garbage collection.
.direnv GC roots:nix-store --gc --print-roots 2>/dev/null | grep '\.direnv' | sed 's|/.direnv/.*||' | sort -u
Show the user how many projects have .direnv roots and list them.
Delete all .direnv directories from those projects:
nix-store --gc --print-roots 2>/dev/null | grep '\.direnv' | sed 's|/.direnv/.*||' | sort -u | while read dir; do rm -rf "$dir/.direnv"; done
.direnv GC roots remain:nix-store --gc --print-roots 2>/dev/null | grep '\.direnv' | wc -l
nix-store --gc to actually reclaim the disk space..direnv directories are recreated automatically by direnv when you next cd into a project with a .envrc, so deleting them is safe.
