One highlighter for the client: a synchronous fine-grained shiki core (JS regex engine, no WASM) in ui-primitives with an explicit grammar allowlist (typescript, shellscript, json — aliases resolve, unknown languages take a geometry-identical plain arm). The shared CodeBlock component owns both arms; markdown fences, the run_code expanded program body (typescript), and the details panel Input (json) all route through it. Token colors live in a new ui-theme shiki.css sheet as --shiki-* custom properties (light/dark blocks), wired through the shell's base.css chain — tokens-only styling holds; shiki's generated span tree is the sanctioned innerHTML path (static output, no user HTML). jsdom specs pin token spans, aliases, both fallbacks, and the fence route; the built-bundle snapshot asserts the highlighted program under the code row.
@deepseek-ai/dsh-client-ui-primitives
Pure React atoms (zero cordis): StateDot, ic_ds_* icons, Button/Pill/Menu/Modal/Input, markdown family (MessageText/MarkdownText/JsonBlock). Contract: api-contracts v3 §8.
Markdown rendering
MarkdownText renders GFM from untrusted assistant output through React elements. It omits raw HTML, neutralizes relative and non-HTTP(S)/mailto links, opens HTTP(S) links with safe external-link attributes, and renders image alt text without loading remote resources; MessageText remains the literal-text primitive for user-authored content.
Model Experience
None, as the package renders pure React atoms in the browser; nothing here reaches a model request.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
- Glyph-level icons are redrawn approximations — the fish logo (and the sparkle held by ui-conversation) come from font glyphs whose vector geometry is not exportable from the local design data; hand-authored recreations stand in until an exact export path exists.
- Pill and Input have no design source — both atoms are self-defined; the sidebar search field and view-tab strip that resemble them are consumer-owned compositions, not these atoms.
- StateDot
Activevariant is a hidden placeholder in the design — not implemented; the four shipped states (done/warning/ongoing/error) are the complete P-I surface.
