Use when the user asks how Yachiyo itself works — what a feature does, what a setting changes, how to set up providers, skills, workspaces, channels, schedules, memory, or sync, where files live, or "what can you do". Reads the official documentation at yachiyo.ringo.sh so answers come from the current docs instead of memory.
Override built-in Markstream node renderers and add trusted custom tags. Use when Codex needs to apply `setCustomComponents`, install `VueRendererMarkdown` with scoped Vue app components, keep overrides scoped with `customId`, map override keys like `image`, `code_block`, `mermaid`, or `link`, or wire `customHtmlTags` and nested renderers for tags such as `thinking`.
Install and wire markstream-vue, markstream-react, markstream-vue2, markstream-angular, or markstream-svelte into an existing repository. Use when Codex needs to choose the right package, install the smallest peer-dependency set, fix CSS/reset order, choose Vue 3 renderer mode, decide between `content`, `nodes`, and Vue 3 virtual-scroll coordination, or add a minimal working renderer example.
Audit and migrate existing Markdown rendering to Markstream. Use when Codex needs to replace another renderer, classify direct vs custom vs plugin-heavy usage, preserve behavior during adoption, migrate custom renderers into scoped Markstream overrides, or decide when `nodes` streaming is worth adopting.
Integrate markstream-react into a React 18+ or Next app. Use when Codex needs to add the React renderer, import CSS correctly, choose between `content` and `nodes`, keep Next client boundaries safe, convert renderer overrides, or prepare a repo for `react-markdown` migration.
Use this skill for browser automation with the useBrowser tool — opening pages, taking snapshots, clicking and filling elements, handling page state, capturing screenshots, extracting page data, and verifying web flows. The user can see and interact with the browser window directly, and you may ask them to handle blocking steps (e.g. CAPTCHA, login, 2FA). Re-snapshot after page changes, use isolated sessions when needed, and always close the browser session when done.
Coding discipline reference for software engineering tasks. Read when starting any nontrivial code work — greenfield projects, bug fixing, writing tests, refactoring, iterating on existing codebases, writing docs, or explaining a codebase. Hub skill that points to task-specific reference files; load the reference that matches the task before editing.
Use this skill for Word document work such as reading `.docx` files, extracting content, editing existing documents, generating new `.docx` files, replacing text, updating tables, handling images, and preserving document structure. Prefer the smallest reliable workflow, keep the original file unchanged unless asked otherwise, and verify the result before finishing.
