Audit and fix HTML accessibility issues including ARIA labels, keyboard navigation, focus management, color contrast, and form errors. Use when adding interactive controls, forms, dialogs, or reviewing WCAG compliance.
Set up infra/AGENTS.md in the current project. Use when starting infra work in a new project, when infra/ directory exists but AGENTS.md is missing, or when the user says "infraセットアップ", "init infra", "infra/AGENTS.md を作る", or "infraのルールを追加して".
Review unresolved PR comments and take action on each one: address valid feedback with a code fix, commit, push, and reply with a linkified commit hash; dismiss invalid feedback with a clear explanation. Trigger when the user says things like "respond to review comments", "handle Copilot feedback", "address PR comments", or "reply to review".
Add a new app installation cookbook in itamae format to the dotfiles cookbooks/ directory. Use this skill whenever the user wants to install a new app, tool, or package via dotfiles, mentions adding something to cookbooks, says "dotfilesに追加", "cookbookを作る", "itamaeでインストール", or asks to track a new tool in the dotfiles repo. Also triggers when the user wants to add an alias or environment variable setup for a new tool.
Stage all changes and create a git commit. Use after finishing an implementation task.
Use the git-wt command to create an isolated Git worktree for a task, keeping the main branch clean. After finishing, clean up the worktree based on whether changes exist. Only trigger when the user explicitly requests worktree isolation — e.g., "use a worktree", "use wt", "work on a separate branch", "isolate this in a worktree".
