Use when the user explicitly asks for "ultraresearch" or a rigorous multi-source investigation — comparative surveys, hypothesis testing, decision-driving research ("徹底調査", "深く調べて"). Prefer over deep-research when the question needs scope clarification (interview), Japanese/paywalled source guidance, or red-team falsification. Not for single-fact lookups.
Grill the user relentlessly about a plan or design. Use when the user wants to stress-test a plan before building, or uses any 'grill' trigger phrases.
Add a new mitamae cookbook for a tool, package, LSP server, or application in this dotfiles repository. Use this skill whenever the user says things like "add cookbook for X", "install X via mitamae", "add X to dotfiles", "add LSP for X", "provision X", "set up X in my environment". Also trigger when the user just names a tool and implicitly expects it to be added to the repo.
Create a new mitamae role for a specific host machine or container in this dotfiles repository. Use this skill when the user says things like "add a role for new PC/machine/server", "create a role for [machine name]", "set up dotfiles for new computer", "configure a new host", or when a new machine needs its own provisioning configuration. Also trigger when the user mentions setting up a new macOS machine or Linux server with a specific purpose.
