Based on SOC occupation classification
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.

Language-aware structural search/replace using AST patterns.
sg --pattern 'console.log($$$ARGS)' --lang js — find all console.log callssg --pattern '$FUNC($$$ARGS)' --rewrite 'newFunc($$$ARGS)' --lang py — rename function callsLanguage-aware structural search/replace with simple hole-matching syntax.
comby ':[fn](:[args])' 'new_:[fn](:[args])' .py — rename function callscomby 'if :[cond] { :[body] }' 'when :[cond] { :[body] }' .rs — syntax migrationDump/inspect the AST of a file to understand its structure.
tree-sitter parse file.py — show full AST
