This skill should be used when the user wants to serve a file, directory, or git diff over Tailscale HTTPS. Triggers on "serve on tailscale", "share via tailscale", "tailscale-serve", "tailscale serve file", "serve diff on tailscale", or /tailscale-serve.
Manage git worktrees with worktrunk (`wt`) -- create, switch, list, merge, remove, and fan out parallel agents into isolated worktrees. Use when the user says "make/create a worktree", "use worktrunk", "wt switch", "new isolated checkout", "open a separate worktree", "list/remove/clean up worktrees", "spin up an agent on a branch / in a worktree", "checkout PR in a worktree", "fan out agents", or wants to run multiple Claude/Codex sessions in parallel on the same repo.
Generate a Brazilian PIX BR Code (EMV) — produces both the Copia e Cola string and a scannable QR PNG. Use when the user wants to create a PIX payment QR, "gere um QR pra esse PIX", "make a PIX QR code", or shares chave + valor and asks for a QR. Supports CPF, CNPJ, email, phone (E.164 or BR-format), and aleatória UUID keys. Amount is optional — omit for payer-fills mode.
Reference for diagram-as-code tools (D2, Mermaid, Graphviz/DOT, Structurizr DSL, PlantUML) and the Kroki HTTP rendering gateway. Use when generating architecture diagrams, flowcharts, sequence diagrams, ER diagrams, C4 models, or graph visualizations.
Get quick code statistics and project overview using tokei or scc
Use a custom direnv `layout_uv()` helper for uv workspaces instead of `source .venv/bin/activate`
Use structural code search and rewrite tools (ast-grep, comby, tree-sitter) for code analysis and refactoring
Use uv with PEP 723 inline metadata to run Python scripts with dependencies instead of installing packages globally
