JSX-MD Authoring

Use this skill for prompt components and Markdown rendering code.

Read First

packages/jsx-md/README.md
packages/jsx-md/src/primitives.tsx
packages/jsx-md/src/render.ts
packages/jsx-md/src/context.ts

Authoring Rules

Prefer JSX-MD components over inline Markdown strings.
Use lowercase XML intrinsics for structured LLM prompt sections such as <context>, <instructions>, and <examples>.
Use Md only as an escape hatch for genuinely undecomposable Markdown.
Escape user-supplied strings with Escape or escapeMarkdown when they should render literally.
Use Codeblock for fenced code and let it choose a safe fence length.
Keep render() deterministic and synchronous.
Do not introduce React or DOM runtime assumptions into jsx-md.
Use context only for cross-cutting rendering state, not arbitrary global state.

Text Rules

Bare JSX text is preferred for plain prose.
Use {...} only when JSX syntax requires it, such as backticks, braces, <, >, or apostrophes inside the text.
Keep XML attributes primitive and serializable.

Verification

Run bun test in packages/jsx-md for renderer changes.
Run bun run typecheck after export, type, or JSX runtime changes.
