Vendors claude-todo-list, claude-diff, and claude-thinking from the brainless shadcn registry (namespace registered in components.json), rethemed from hard-coded terminal hex colors to the paper/ink tokens so they read as native in both light and dark themes. The thinking line drops the fabricated token counter and the esc-to-interrupt hint — neither is true in the web chat. New always-on render_ui system tool: presentation-only, the web renders the call's INPUT so blocks appear progressively while arguments stream. todo_list renders a status checklist; diff renders a before/after hunk computed client-side by the ToolBlock differ (now exported). Failed or unrecognized calls fall back to the generic ToolBlock; the TUI shows raw arguments. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Summary
Integrates the brainless shadcn registry so agents can dynamically pick rich UI blocks when answering in the web chat.
render_uisystem tool — presentation-only; the web renders the call's input, so blocks draw progressively while arguments stream. Two components in v1:todo_list(plan/checklist with per-item status) anddiff(before/after hunk for one file, computed client-side by the exported ToolBlock differ).claude-todo-list,claude-diff,claude-thinkingunderapps/web/app/components/brainless/claude/, with the@brainlessnamespace registered incomponents.jsonfor future adds.#101010background) that clash with the app theme and break in light mode. Structure, glyph grammar, and a11y semantics (sr-onlylabels,role="status",aria-live) are preserved; colors map tosignal-green/plot-red/ink-*/paper-*so both themes work for free. The thinking line drops the fabricated token counter and "esc to interrupt" hint.ClaudeThinkingline.render_uicalls fall back to the genericToolBlock; the TUI shows raw arguments.Testing
packages/tools/test/render-ui.test.ts); full workspace type-check, lint, and tests pass (pre-commit hook ran all 30 tasks).🤖 Generated with Claude Code
