After many years across Windows, macOS and Ubuntu-based distros, the laptop has run CachyOS since June 2026.

• CachyOS: Arch with an optimized kernel and packages. I came from ZorinOS and a few months of Omarchy, and this is where I stayed.
• Niri: Wayland compositor that lays windows out in scrollable columns. I have a shortcut for almost everything, and messaging and music apps live in scratchpads that show and hide with one key.
• Noctalia: The whole shell: bar, launcher, notifications and lock screen. It has a plugin system, and that is what got me writing my own.Ctrl + Space launcherSuper + Alt + B restarts the shell

• Ghostty: My everyday terminal, with selection going only to the primary clipboard so I can paste with the middle button.Super + Enter
• Zsh com Oh My Zsh: My usual shell, with my Git, system and utility scripts versioned in the dotfiles repo.
• mise: One manager for Node, Python and the rest. It replaced nvm, pyenv and company.
• RTK: A CLI proxy that trims command output before it reaches the agent. It saves context, with one caveat: it cuts long lists, so to check something for real I call the binary directly.
• btop: To see what is eating CPU and memory when tests or a build get heavy.Super + Alt + T
• VS Code e Neovim: Both stay configured in my dotfiles, but most of the code today comes from the agents.Super + Shift + I VS Code

I work in an RPI flow (research, plan and implementation), with one agent for each role.

• Claude Code: It leads: researches, writes the spec and the plan, validates, reviews and commits. On top of it runs my framework of skills, rules, hooks and memory.Super + Shift + Enter opens in a new Ghostty
• Grok CLI: Implements the plan tasks, one at a time, with no permission to run git.
• Antigravity CLI (agy): Reviews each task diff in a throwaway copy of the repo, as a second model beside the Claude Code review.
• Ollama e OpenCode: Local AI, with qwen2.5-coder running on the machine itself.

• Google Chrome: My main browser. A script makes Niri focus its window when a link opens from another app.Super + Shift + BSuper + Shift + Alt + B incognito
• 1Password: Passwords, keys and secrets. It is one of the two apps that start with the session, and quick access sits on Ctrl+Shift+Space.Ctrl + Shift + Space quick access

• Pi-hole: Home DNS: blocks ads and resolves the .home names of the services.
• Caddy: The reverse proxy that puts each container behind a name. Staging for this site lives behind it.

When I could not find the tool, I wrote it. All open source, with the case in the lab.

• Daybar: Quick capture, Google Calendar agenda, focus timer, favorites and Markdown notes, on the Noctalia bar.Super + Space quick captureSuper + Shift + Space panel
• AI Bar: How much of the Claude Code and Grok plan is already used, and the usage pace of each window.

• Desktop Sticky Notes: Markdown sticky notes pinned to the desktop.
• Forja: Desktop client that brings Claude Code, Codex and Gemini into one interface.

• Omarchy: DHH's distro, with Hyprland. I used it for a few months before landing on CachyOS.
• Model Usage: Noctalia plugin for AI model usage. I used it for months, until I wrote AI Bar.
• Gemini no fluxo de implementação: It did the final validation of tasks. It left because the free plan was too fragile: request limits blowing up mid-run.
• Codex: It started by committing, until it got a list with one file and made five commits. It moved to only reviewing the diff in a read-only sandbox, and later left the RPI flow, which today is Claude Code, Grok and agy.
• TickTick: Task app that lived in a Niri scratchpad on Super+Shift+T. It left autostart and then the routine.
• VLC: Replaced by mpv as the default player.
