// Automate browser interactions from the shell using Playwright via the `playwright-cli` command (open/goto/snapshot/click/type/screenshot, tabs/storage/network). Use when you need deterministic browser automation for web testing, form filling, screenshots/PDFs, or data extraction.
Use when user asks to bump, update, or upgrade claude-code or codex versions in overlay.nix, or when checking if newer versions are available
Investigate and safely reclaim disk space on this machine, especially on NixOS systems with heavy Nix, Rust/Haskell, Docker, and Podman usage. Use when disk is low, builds fail with no-space errors, /nix/store appears unexpectedly large, or the user asks for easy cleanup wins without deleting important data.
Use when doing NixOS rebuilds involving taffybar, or when flake.lock updates are needed after changing taffybar ecosystem packages. Also use when debugging stale taffybar versions after `just switch`.
Use when user wants to find promotional or unwanted recurring emails to unsubscribe from, or when doing periodic inbox hygiene to identify senders worth unsubscribing from
Use when the user wants to reset or rotate a website or service password end-to-end, including finding the right `pass` entry, generating a new password with `xkcdpassgen`, retrieving reset emails through `gws gmail` or a local mail CLI, completing the reset in the browser with Chrome DevTools MCP, and updating the password store safely without losing entry metadata.
Review or prepare nixpkgs package changes and PRs using a checklist distilled from review feedback on Ivan Malison's own NixOS/nixpkgs pull requests. Use when working in nixpkgs on package inits, updates, packaging fixes, or before opening or reviewing a nixpkgs PR.
