Dotfiles steward loop — keep this machine's shared-repo checkout synced, green, and fixed, coordinating with the other machines' stewards over SSH. Use each heartbeat and when asked to sync, validate, or fix the dotfiles.
Interact with a live webpage inside a browser window — fill forms, click buttons, navigate authenticated apps, automate Electron apps, test web UI, capture browser-window screenshots for visual verification of web pages. Do NOT use for fetching or reading web content programmatically (use curl or MCP fetch). Do NOT use for desktop screenshots, system media/audio control, MPRIS players, or non-browser GUI — those belong to the desktop skill.
Nix everything — language expertise (lazy eval, derivations, overlays, module system, flakes, agenix, cachix), applying config via rebuild, devenv project shells, THIS dotfiles repo conventions (module layout, isNixOS, script packaging, secrets, channels), and Docker/Podman container management via the docker-manager script. Use for any .nix edit, rebuild, devenv shell, container lifecycle, or "where does this belong in the dotfiles" question.
Log into and scrape data from Lucas's B3 Área do Investidor (investidor.b3.com.br) via browser-use MCP plus raw CDP XHR capture. Use when syncing portfolio positions, trades, dividends, or any other read-only data from B3 — for example when Golden runs b3-sync, or when verifying brokerage state. Documents the working flow, the SPA quirks that broke prior attempts, the API endpoint catalog, and the institution-CNPJ filter trick.
Master index for every personal skill — discover what is available without loading the full set into context. Run the listing script to enumerate top-level skills (git, nix, browser, comms, review, session, test, ...) and umbrella chapters (Lucas's channels — Gmail, Calendar, WhatsApp, Google Chat, Obsidian, Twitter/X, Ponto, Home Assistant, phone status). Use whenever work might benefit from a personal-only skill, or when the user mentions any topic this index covers.
Manage today's daily manager report file. Use when the user asks to generate, update, or finalize their standup or manager update, or when a meaningful unit of work should be logged into today's report.
Send Google Chat messages, DMs, webhooks. Post and scrape Twitter/X tweets, profiles, trends. Control VTuber avatar lip sync and expressions.
Control the VTuber avatar — start and stop the renderer, virtual camera, and virtual mic; speak through the avatar with lip sync; respond to voice conversation when hey-bot is active.
