## Description

Integrate markstream-vue2 into a Vue 2.6 or 2.7 app. Use when Codex needs Vue 2-compatible setup, `@vue/composition-api` decisions, CSS wiring, optional peer setup, or scoped Markstream overrides in a Vue 2 repository that is not specifically Vue CLI / Webpack 4 constrained.

# Markstream Vue 2

Use this skill when the host app is Vue 2 and not specifically a Vue CLI / Webpack 4 edge case.

## Workflow

1. Confirm the repo is Vue 2.6 or 2.7.
2. Install `markstream-vue2`.
   - Add `@vue/composition-api` only when the repo is Vue 2.6 and uses Composition API patterns.
3. Import `markstream-vue2/index.css` after resets.
4. Start with `<MarkdownRender :content="markdown" />`.
   - For AI chat or streaming UIs, keep `content` and use built-in smooth streaming first.
     - `smooth-streaming="auto"` is the default and activates when `typewriter=true` or `max-live-nodes <= 0`.
     - `typewriter` only controls the blinking cursor and defaults to `false`.
     - `fade` controls node enter and streamed-text fade animations and defaults to `true`.
   - **Streaming vs recovering history**: in chat UIs the same `MarkdownRender` starts streaming and later switches to history when `final=true`.
     - Streaming: `smooth-streaming="auto"`, `:fade="false"`, `typewriter=true`. This is a conservative visual/performance choice, not an API incompatibility. This adapter has not adopted Vue 3's bounded append fades, so verify its animation behavior before enabling both.
     - Recovering history: `:smooth-streaming="false"`, `:fade="true"`, `typewriter=false`. Content is already complete, pacing would slow it down, but fade gives a polished entry animation.
     - Dynamic switch: `:smooth-streaming="isStreaming ? 'auto' : false"`, `:fade="!isStreaming"`.
   - Move to `nodes` + `final` only for worker-preparsed content, shared AST stores, or custom AST control.
   - Remember that `html-policy` now defaults to `safe`, and Mermaid strict mode is on by default through `mermaid-props`.
5. Use scoped custom component mappings when the task needs overrides or trusted tags.
6. Validate with the smallest useful dev or build command.
