What it does

Markstream Custom Components is an agent skill from Simon-He95/markstream-vue. Override built-in Markstream node renderers and add trusted custom tags across Vue, React, Svelte, and Angular. Use when Codex needs scoped setCustomComponents, renderer-local React streamingComponents or htmlComponents, Angular/Svelte customComponents, Vue app-scoped components, node override keys such as image, codeblock, mermaid, or link, or nested renderers for tags such as thinking.

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/patterns.md`).

It sits in Development, covering Diagrams. It works with Vue.js, Angular, Svelte and React. 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 scoped setCustomComponents
  • Renderer-local React streamingComponents
  • Angular/Svelte customComponents
  • Vue app-scoped components

Example prompts

  • “/markstream-custom-components”

Workflow steps

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

  1. Classify the request.
  2. Prefer scoped mappings.
  3. Start with the smallest safe override.
  4. Preserve nested Markdown when needed.
  5. Keep props and cleanup intact.
  6. Validate with the smallest useful check.

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 Custom Components loads about 955 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 110 tokens; SKILL.md has 404 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~110
When it runs · the whole SKILL.md, loaded when a task matches
~955
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

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
Override built-in Markstream node renderers and add trusted custom tags across Vue, React, Svelte, and Angular. Use when Codex needs scoped `setCustomComponents`, renderer-local React `streamingComponents` or `htmlComponents`, Angular/Svelte `customComponents`, Vue app-scoped components, node override keys such as `image`, `code_block`, `mermaid`, or `link`, or nested renderers for tags such as `thinking`.

Markstream Custom Components

Use this skill when the task is to change how Markstream renders specific nodes or custom tags.

Read references/patterns.md before choosing an override strategy.

Workflow

  1. Classify the request.
    • built-in override: replace an existing renderer such as image, link, code_block, mermaid, d2, or inline_code.
    • custom tag: support trusted HTML-like tags such as thinking.
    • parser-level: requires token transforms or AST reshaping. Only then should you leave this skill and use low-level parser hooks.
  2. Prefer scoped mappings.
    • Vue, Vue 2, Svelte, and shared Angular registration: use setCustomComponents(customId, mapping) instead of global mappings whenever practical, and pass the same customId / custom-id.
    • React custom tags: prefer renderer-local streamingComponents for parser-backed nodes or htmlComponents for sanitized HTML props plus children. Use defineStreamingComponents(...) / defineHtmlComponents(...) for typed maps. Keep setCustomComponents for built-in node overrides or shared legacy registration.
    • Svelte and Angular can also pass a renderer-local customComponents map when the override should not enter the shared registry.
    • In Vue 3 app/plugin setup, import { VueRendererMarkdown } from markstream-vue and install it with { components } when the override should be scoped to the Vue app instance.
  3. Start with the smallest safe override.
    • Leaf-like nodes (image, link, inline_code, mermaid) are easier than container nodes (heading, paragraph, list_item).
    • If the request only changes Mermaid, use mermaid, not code_block.
  4. Preserve nested Markdown when needed.
    • For trusted custom tags with inner Markdown, render node.content with a nested renderer.
    • Pass the same custom-tag allowlist to nested renderers.
    • Nested renderers inside a smooth-streaming parent are automatically suppressed from double pacing — do not add smooth-streaming to child renderers.
    • In React, streamingComponents automatically contributes its keys to the effective custom-tag list; do not duplicate those keys in customHtmlTags unless another parser path needs them.
  5. Keep props and cleanup intact.
    • Preserve node, loading, indexKey, customId, and isDark.
    • For mermaid and infographic overrides, preserve estimatedPreviewHeightPx so async preview shells keep stable height during remounts.
    • Remove temporary scoped mappings with removeCustomComponents(customId) when the scope is no longer needed.
  6. Validate with the smallest useful check.
    • Prefer a local demo, targeted test, or docs build.
    • Call out whether the implementation is safe for repeated and nested custom tags.

Default Decisions

  • Scoped overrides first, global overrides only when the whole app truly needs them.
  • Leaf-node overrides before container-node overrides.
  • customHtmlTags plus scoped custom components before parser hooks.
  • In React, renderer-local component maps before registry mutation.
  • Nested renderers for tag bodies that contain Markdown.

Useful Doc Targets

  • docs/guide/custom-components.md
  • docs/guide/react-components.md
