ui-design

Visual design guide for clide UI development — covers theme tokens, surface-specific token selection, control geometry/spacing/alignment, and Phosphor icons. Use when building or modifying widgets, panels, pane chrome, status indicators, tabs, list items, dialogs, or any visual surface. Triggers on: new widget code, theme-related changes, "which token", "what color", color/background questions, visual inconsistency fixes, "alignment off", "spacing", "padding", control geometry questions, new panel/pane/view development, adding or looking up Phosphor icons, icon codepoints.

UI design — clide visual surface guide

This skill bundles four concerns that all surface in widget work:

Concern	Reference	When to read
Token system, palette, typography	references/theme.md	Designing or extending the theme pipeline; deciding whether to add a new token
Token selection per surface	references/surface.md	Building a new widget or modifying an existing one — "which token does this need"
Spacing, alignment, control layout	references/geometry.md	Building tab strips, list items, buttons, anything where icons sit next to text or padded edges
Phosphor icon usage and codepoints	references/icons.md	Adding or referencing an icon
Full Phosphor glyph table (1512, with codepoints)	references/phosphor-glyphs.md	Picking a specific glyph by name/look — find its codepoint, see if it's already defined

Read the reference that matches the question. They cross-reference each other where relevant; you don't need to read all four.

Universal rules

These apply across every reference and every surface:

• All colors come from SurfaceTokens via ClideTheme.of(context).surface. Never hardcode Color(0xFF...).
• Never use Material* or Cupertino* widgets or color constants — clide is WidgetsApp only (D-7).
• Use ClideText for themed text; never bare Text in production widgets.
• Typography sizes: clideFontMono for code/paths/IDs, clideFontCaption for status/section headers, body inherits from DefaultTextStyle.
• Font family comes from the user-selectable facade, not a const: a monospace surface uses fontFamily: ClideSettings.fonts.monoOf(context) (and fontFamilyFallback: clideMonoFamilyFallback); the UI face is inherited via the root DefaultTextStyle, or ClideSettings.fonts.uiOf(context) when a widget must set it explicitly. clideMonoFamily / clideUiFamily are the facade's defaults — don't read them directly in new widgets (D-101). Same facade exposes ClideSettings.theme.of(context) and .i18n.of(context).

Conversation-panel cards (T-305)

The Claude conversation stream has three card categories. They are NOT one shared wrapper widget — each is its own widget; they only share the spacing constants in lib/widgets/src/clide_card_metrics.dart (kClideCardGap, kClideCardRadius, kClideCardHeaderPadH/V, kClideCardCounterSlotWidth) so the stream reads as one rhythm. Change spacing there, not per-card.

1. Dialog cards — ConversationCard with a speaker side stripe (you / claude / agent). Prose/attribution; not collapsible.
2. Simple cards — a single item shown fully open, never collapses (e.g. the image card). Standalone display; no chevron, no status chrome.
3. Collapsibles — ClideCollapserCard (lib/widgets/). Every tool use is one, over a list of 1..N inner item cards (a single tool = a 1-item list; there is no separate single-card path). Rules:
   • Whole card toggles; chevron hard against the left edge, the status tick (spinner/check/cross) hard against the right edge, the count in a fixed-width slot just inboard of it.
   • color drives the border + chevron/label tint (per-instance fidelity).
   • Collapsed ticker echoes the run's last content line as the title + count + aggregate status (computed by the caller, bubbled up from items).
   • Inner item cards are content + their own per-item status; they pass margin: EdgeInsets.zero-ish (a bottom margin matching the canvas) so the collapser pads the inner canvas evenly on all sides — never let an inner card jam under the header or against a frame edge.

Do NOT pull a dialog card's stripe or a simple card's config into the collapser, and do NOT nest collapsers — inside a run, tools render as the bare inner content card (_ConversationTurn(collapseTools: false)).

Anti-patterns (cross-cutting)

• Borrowing another surface's token (sidebarBackground for hat bar) — give each surface its own token even if they share a palette key. See theme.md.
• Hardcoded hex colors → use a token. See surface.md for which one.
• fontSize: 14 literal → use clideFontCaption or clideFontMono.
• fontFamily: 'JetBrainsMono' literal → use clideMonoFamily.
• Stacking edge padding on a padded parent + a padded child action → see geometry.md "no double edge padding".
• Eyeballing pixel margins instead of working back from the constraint — the math matters; see geometry.md "uniform inner spacing".
