What it does

Markstream React is an agent skill from Simon-He95/markstream-vue. Integrate the beta markstream-react package into a React 18+ or Next app. Use when Codex needs to add the React renderer, choose the root, next, or server entrypoint, import CSS correctly, choose between content and nodes, keep client boundaries safe, add renderer-local streamingComponents or htmlComponents, use parser transforms, or prepare a repo for react-markdown migration.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Documents & Office, covering Markdown. It works with React, Vue.js and Mermaid. The repository describes itself as: Multi-framework streaming Markdown renderers for AI apps: Vue/Nuxt, React/Next.js, Svelte, and Angular, with Mermaid, KaTeX, stream-diffs code blocks, safe HTML, and low-jitter… The licence is MIT.

When your agent uses it

  • Codex needs to add the React renderer
  • Choose the root
  • Server entrypoint
  • Import CSS correctly

Example prompts

  • “/markstream-react”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Confirm the repo is React 18+ or a compatible Next host and accepts a beta renderer API.
  2. Install markstream-react plus only the requested optional peers.
  3. Import markstream-react/index.css from the app shell or client entry.
  4. Choose the entrypoint that matches the rendering boundary.
  5. Start with content.
  6. Respect SSR boundaries in Next.
  7. Use renderer-local components before custom parser work.
  8. Validate with the smallest useful dev, build, or typecheck command.

What it can do on your machine

Read from SKILL.md and the folder at commit d5d0c00. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Markstream React loads about 1.2k tokens when it runs. Until then it costs about 103 tokens; SKILL.md has 510 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~103
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Integrate the beta markstream-react package into a React 18+ or Next app. Use when Codex needs to add the React renderer, choose the root, `next`, or `server` entrypoint, import CSS correctly, choose between `content` and `nodes`, keep client boundaries safe, add renderer-local `streamingComponents` or `htmlComponents`, use parser transforms, or prepare a repo for `react-markdown` migration.

Markstream React

Use this skill when the host app is React or Next and the task is to wire Markstream safely.

Workflow

  1. Confirm the repo is React 18+ or a compatible Next host and accepts a beta renderer API.
  2. Install markstream-react plus only the requested optional peers.
  3. Import markstream-react/index.css from the app shell or client entry.
  4. Choose the entrypoint that matches the rendering boundary.
    • Use markstream-react for the normal client renderer.
    • Use markstream-react/next for the Next-specific component surface.
    • Use markstream-react/server for server rendering without client hooks.
  5. Start with content.
    • For streaming or high-frequency AI output, keep content and use built-in smooth streaming first.
      • smoothStreaming="auto" is the default and activates when typewriter={true} or maxLiveNodes <= 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 renderer starts streaming and later switches to history when final={true}.
      • Streaming: smoothStreaming="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: smoothStreaming={false}, fade={true}, typewriter={false}. Content is already complete — pacing would slow it down, but fade gives a polished entry animation.
      • Dynamic switch: smoothStreaming={isStreaming ? 'auto' : false}, fade={!isStreaming}.
    • Move to nodes + final only for worker-preparsed content, shared AST stores, or custom AST control.
    • Remember that htmlPolicy now defaults to safe, and Mermaid strict mode is on by default through mermaidProps.
  6. Respect SSR boundaries in Next.
    • Prefer use client, dynamic imports with ssr: false, or other client-only boundaries when browser-only peers are involved.
  7. Use renderer-local components before custom parser work.
    • streamingComponents receives parser-backed NodeComponentProps, supports incomplete custom tags, and automatically contributes its keys to the effective customHtmlTags list.
    • htmlComponents receives sanitized HTML attributes plus children; it does not receive the parser node/loading contract.
    • Prefer defineStreamingComponents(...) and defineHtmlComponents(...) for typed maps.
    • Keep scoped setCustomComponents for built-in node overrides or shared compatibility registration.
    • Use parseOptions transforms only when migration requires token or AST changes.
  8. Validate with the smallest useful dev, build, or typecheck command.

Default Decisions

  • Renderer wiring first, migration cleanup second.
  • If the repo already uses react-markdown, pair this skill with markstream-migration.
  • Prefer content with built-in smooth streaming for most AI chat / token streaming surfaces.
  • Streaming vs recovering history: when a chat message transitions from streaming to history (e.g. final becomes true), switch props dynamically — smoothStreaming="auto", fade={false} for streaming; smoothStreaming={false}, fade={true} for history. See docs/guide/ai-chat-streaming.md for full examples.
  • Move to nodes only when another layer owns parsing or AST transforms.
  • Prefer renderer-local custom-tag maps over global registry mutation.
  • Prefer the smallest client-only boundary that solves the SSR issue.
  • Avoid smoothStreaming={true} for first-screen SSR content unless intentionally starting from blank; auto mode uses the mounted gate.
  • Keep htmlPolicy="safe" and Mermaid strict mode unless the request is preserving trusted legacy rendering.
  • If a trusted surface needs older behavior, use htmlPolicy="trusted" and mermaidProps={{ isStrict: false }} only on that surface and explain why.
