 The process group uses a stable `div` layout box, a scroll body, and an uncapped content box that reports growth inside the body. Business styles must adapt spacing within and across groups, including hidden or empty members and the answer-spacing exception. CSS variables do not belong in the Group Definition.
 
+Running group titles, reasoning previews, tool and command rows, the active retry line, and the bottom running status use the shared [TextShimmer](../ui-primitives/README.md#component-catalog). Each row’s text shares one left-to-right highlight, including collapsed group titles; icons and hover chevrons retain their base appearance. Tool and process rows sit 6px apart. An expanded group title has 8px before its content, Assistant responses have 12px from adjacent process rows, and completed-Turn duration/status controls have 16px around them. Hidden and empty rows, including retained empty slot anchors, add no gap. The running “Deep diving” text retains its blue base while its theme-specific highlight sweeps across it.
+
 Scroll-edge fades initialize when `ResizeObserver` reports the open group's layout; opening the group performs no immediate scroll-dimension read in a layout effect.
 
 Each group owns local `useDisclosure` state that survives mode changes while its component stays mounted.

 | `ConnectionIndicator` | Inline connection-recovery control across outage, retry, and recovered states. |
 | `DisclosureRow` | 24px compact disclosure that lays title and content side by side. Memoized with shallow prop comparison; keep callbacks and React-node props stable when their content is unchanged. |
+| `TextShimmer` | One left-to-right highlight across a row’s title, separators, summary, and suffix, with a 300ms initial delay, a one-second sweep and a 500ms rest. The mask spans the content width, capped by the visible row and tilts 15° from vertical, with a flat peak and soft edges. The moving decoration stays clipped to the row without enlarging its scrollable area. Base text inherits the caller’s color, including hover changes; the theme supplies the translucent highlight. Place icons and chevrons outside `TextShimmer` so only text and separators receive the highlight. A string child uses the same retained text interface; nested `TextShimmer` instances share the outer animation. Composite children render twice while active and must have no effects or element ids. Mark separators with `data-shimmer-decoration` so their fill receives the highlight. `DisclosureRow` forwards `contentClassName` for the text area and `contentLayoutClassName` for its inner layout. The inert decorative copy is excluded from interaction, selection, and accessibility; text updates retain the animation, and reduced-motion mode keeps the static base. |
 | `Modal` | Centered dialog over a page mask. A nested dialog can intercept keys with `onKeyDownCapture` before document Escape handlers. The tint and dialog fade in while backdrop blur stays fully applied, honoring reduced motion. Set `backdropBlur={false}` when the caller already blurs the source page. |
 | `RiskConfirmation` | Sensitive action gated behind an explicit checkbox. |
 | `Tooltip` | Hover and keyboard-focus text anchored to a cloned child; optional `delayMs` controls hover delay and `focusDelayMs` controls keyboard-focus delay, both defaulting to 0 ms. Optional `portal` rendering escapes clipping containers and ancestor stacking contexts that cap the bubble's z-index. |

+A collapsed row renders the skill glyph, `Skill` title, and requested skill name on the same secondary font-size axis, line height, row height, and glyph scaling as ordinary Tool rows. Every lifecycle state retains the ordinary skill glyph; running calls carry one left-to-right highlight across the title, separator, and skill name, while failures replace the name with the first error line and interruptions retain their explicit status text.

 Hovering over `/name` highlights the entire reference. Clicking a known skill opens its provider-supplied `SKILL.md` path in the right Sidebar while keeping the token editable. An uncached click shares the per-Session catalog fetch and opens when it completes, retaining the clicked Session address. Preset changes, connection resets, and plugin disposal cancel pending previews; a later click fetches the current catalog again. Skills without a file path remain invocable but have no file preview.

 System toasts use `--dsw-alias-toast-bg` and `--dsw-alias-toast-label` for a shared background and text color across callers. Document previews pair `--dsw-alias-bg-document-preview` with `--dsw-alias-label-document-preview` so the backdrop and status text follow the same theme. Tooltip keycaps use `--dsw-alias-tooltip-key-bg`, a lighter fill derived from the tooltip background in each palette. Switch thumbs read `--dsw-alias-switch-thumb`: white in light mode and neutral-bluish 400 in dark mode, so an off switch stays lighter than its track without the glare of pure white.
 
+`--dsw-alias-label-shimmer` supplies an overlay for the shared text shimmer: black at 30% alpha in the light palette and white at 45% alpha in the dark palette. `--dsw-alias-label-deep-diving` and `--dsw-alias-label-deep-diving-shimmer` supply the blue activity label and sweep; the dark palette uses a lighter, less saturated label with a brighter blue sweep.

 `brand-font.css` exports the local Montserrat Light, Regular and Medium faces (normal style, weights 300, 400 and 500), with `montserrat-light.woff2`, `montserrat-regular.woff2`, `montserrat-medium.woff2` and its SIL Open Font License in `lib/styles/`. Desktop bundles the same stylesheet, font and license for offline welcome brand text; ordinary UI keeps its system font stack.
 
 `corner-shape.css` smooths every rounded corner: inside `@supports (corner-shape: superellipse(1.5))` it defines `--dsw-corner-shape` and applies it to all elements and their `::before`/`::after` through the universal selector, so engines without `corner-shape` keep circular corners. Full-round shapes — `border-radius: 50%` circles and pill radii — pair `corner-shape: round` with their radius in the owning component sheet because a superellipse deforms them; the corner-shape stylesheet spec enforces that pairing across every package stylesheet.

 `corner-shape.css` 平滑所有圆角：在 `@supports (corner-shape: superellipse(1.5))` 内定义 `--dsw-corner-shape`，并通过通配选择器应用到所有元素及其 `::before`/`::after`，因此不支持 `corner-shape` 的引擎保持普通圆弧。正圆形状——`border-radius: 50%` 的圆与胶囊半径——因超级椭圆会使其变形，须在所属组件样式表中把 `corner-shape: round` 与半径声明配对；corner-shape 样式表 spec 跨全部包样式表强制这一配对。

 Every registered view receives the explicit `preparing`, `start`, and `result` props declared in [the Tool slot types](src/client/contract/slots.ts). Shared rows use the same `ToolRow` in all stages. Their row model selects the title and combines any generic tool-name prefix with the available argument summary independently of lifecycle state. Tool-owned titles omit the English name. The shared argument parser returns no call during preparation and does not parse partial JSON. Write/edit use separate preparing and dispatched components, so only the preparing component invokes `useToolCallArgumentsPartial`; start and result share the dispatched component. Custom renderers such as Bash, Skill, and Cordis handle preparation separately; their argument-dependent components accept `StartedToolCallViewProps`.
 
-This package owns the generic fallback and the built-in shell/pwsh, read, read_image, write/edit, running `str_replace_editor` `create`/`str_replace`, grep/glob, web, todo, question, and PTC dispatch presentations. Structured cards derive directly from first-party raw event fields; Host `presentCall` and `presentResult` values never enter the Client. Running and settled foreground standard `bash`/`pwsh` and `terminal_send` calls use terminal cards at the root and in PTC dispatch children, subject to the same argument, result, and error checks. Persistent `bash`/`pwsh` calls use terminal cards only while running. Shell output ending in a recognized spill-policy notice uses expandable generic output in shell rows and generic output in Details; a displaced or omitted exit marker cannot establish success. Settled persistent-shell results stay generic because reset and partial-output diagnostics do not always describe one process exit status; root persistent results are expandable, while background acknowledgements remain collapsed. A native or PTC dispatch failure carrying `AUTO_REVIEW_DENIED` shows the Auto review verdict in its collapsed row and one normalized not-executed reason when expanded; a missing or whitespace-only reason uses localized fallback text. A successful question row pairs call questions with result answers by their stable ids and shows readable question/answer lines when expanded. A cancelled or interrupted row shows its verdict and original questions without inventing answers. Unsupported, malformed, or ambiguous inputs fall back to flattened Tool input/result text. `ui-skill` demonstrates a business-owned registration for `skill`.

 每个注册视图都接收[工具 slot 类型](src/client/contract/slots.ts)声明的显式 `preparing`、`start` 和 `result` props。通用行在三个阶段使用同一个 `ToolRow`。行模型统一选择标题，并组合通用工具名前缀与已有参数摘要，不按生命周期阶段改变前缀；专用标题不附带英文名。准备阶段的共享参数解析入口直接返回无调用，不解析部分 JSON。write/edit 将准备态和派发后阶段拆成两个组件，只有准备态组件调用 `useToolCallArgumentsPartial`，start 与 result 共用派发后组件。Bash、Skill、Cordis 等自定义 renderer 分别处理准备态，其依赖参数的组件接收 `StartedToolCallViewProps`。
