You are a Claude-Mem, a specialized observer tool for creating searchable memory FOR FUTURE SESSIONS.
CRITICAL: Record what was LEARNED/BUILT/FIXED/DEPLOYED/CONFIGURED, not what you (the observer) are doing.
You do not have access to tools. All information you need is provided in <observed_from_primary_session> messages. Create observations from what you observe - no investigation needed.
<observed_from_primary_session> <user_request>claude-mem:learn-codebase</user_request> <requested_at>2026-05-20</requested_at> </observed_from_primary_session>
Your job is to monitor a different Claude Code session happening RIGHT NOW, with the goal of creating observations and progress summaries as the work is being done LIVE by the user. You are NOT the one doing the work - you are ONLY observing and recording what is being built, fixed, deployed, or configured in the other session.
SPATIAL AWARENESS: Tool executions include the working directory (tool_cwd) to help you understand: - Which repository/project is being worked on - Where files are located relative to the project root - How to match requested paths to actual execution paths
WHAT TO RECORD
Focus on durable technical signal: - What the system NOW DOES differently (new capabilities) - What shipped to users/production (features, fixes, configs, docs) - Changes in technical domains (auth, data, UI, infra, DevOps, docs) - Concrete debugging or investigative findings from logs, traces, queue state, database rows, and code-path inspection
Use verbs like: implemented, fixed, deployed, configured, migrated, optimized, added, refactored, discovered, confirmed, traced
✅ GOOD EXAMPLES (describes what was built or learned): - "Authentication now supports OAuth2 with PKCE flow" - "Deployment pipeline runs canary releases with auto-rollback" - "Database indexes optimized for common query patterns" - "Observation queue for claude-mem session timed out waiting for an agent pool slot" - "Fallback processing abandoned pending messages after Gemini and OpenRouter returned 404"
❌ BAD EXAMPLES (describes observation process - DO NOT DO THIS): - "Analyzed authentication implementation and stored findings" - "Tracked deployment steps and logged outcomes" - "Monitored database performance and recorded metrics"
WHEN TO SKIP
Skip routine operations: - Empty status checks - Package installations with no errors - Simple file listings with no follow-on finding - Repetitive operations you've already documented - File related research that comes back empty or not found
If skipping, return an empty response only. Do not explain the skip in prose.

<narrative>The Oxygen design system is a Nx-managed monorepo with npm workspaces. Core package contains 300+ components organized into 8 categories (actions, collection, dataDisplay, feedbacks, forms, layout, navigation, overlays). B2B and B2C packages provide variant components. Supporting packages handle icons, illustrative icons, design tokens via Style Dictionary, toast notifications, codemods for migrations, and Storybook infrastructure. The project uses TypeScript, React 18/19, CSS Modules, SCSS, Tailwind CSS, and React Aria for accessibility.</narrative>

</facts>
<narrative>The project maintains a documentation index that maps developer workflows to specific documentation files. Rather than preloading all docs, the index guides developers to load only relevant files for their current task—e.g., "Create a new component" loads component-patterns.md, component-lifecycle.md, code-style.md, token-reference.md, storybook-patterns.md, and component-index-{package}.md. Documentation covers code patterns, accessibility requirements, testing strategy, styling/tokens, component lifecycle maturity stages, Figma integration, form patterns, icon catalogs, code quality principles, and CI/CD workflows. External Storybook manifests provide machine-readable component catalogs for runtime API lookups.</narrative>

</facts>
<narrative>The Oxygen repo maintains two separate skill/agent directory trees with distinct purposes. Repo-root directories (skills/, agents/) are published for external users via the plugin manifest (.claude-plugin/plugin.json) and can be consumed by external Claude users. Internal .claude/ directories contain workflow skills, agent instructions, behavioral rules, and git hooks used only within the repo's Claude Code configuration. This separation allows the project to ship redistributable automation while maintaining internal development workflows.</narrative>

</facts>
<narrative>Each Oxygen component follows a standard colocated file structure. Main implementation lives in Component.tsx with TypeScript props interface. Styles use CSS Modules (all new components); CSS tokens are split into 3 tiers (component-scoped, semantic, primitive). Storybook stories document usage with Overview pattern + named stories using .map() for variant matrices. Interaction tests verify user behavior; A11y tests verify accessibility contracts. Test helpers provide semantic query functions (buildRoleQueries, buildDSComponentQueries) for consumer tests. Figma Code Connect (.figma.tsx) maps Figma properties to React props. Migration logic in optional .migration.ts. Optional v2/ subdirectory houses next-generation versions. The structure emphasizes colocation of related files and avoids barrel exports for cleaner tree-shaking.</narrative>

<narrative>Oxygen components progress through four maturity stages. Draft is pre-implementation. Alpha is experimental with breaking changes likely. Beta is nearly production-ready, has test helpers and documentation, limited access during beta program. Stable is mature with 80%+ test coverage, complete documentation, and public API. Each stage transition has specific requirements checked via Storybook story tags and stageChecklist parameters. Stories organized by stage in the filesystem. The private tag hides alpha and internal components from main Storybook navigation, revealing them only to contributors. This lifecycle system ensures quality and communicates expectations to consumers.</narrative>

</facts>
<narrative>Oxygen enforces strict code style rules to maintain consistency and prevent subtle bugs. Props follow semantic naming (is/has/should for booleans, on for events). All optional props must explicitly accept undefined and have default values to avoid undefined-value friction. Types are restricted to specific union types rather than generic strings, enabling compile-time validation and self-documenting APIs. JSDoc is required but must earn its place—only properties that code alone doesn't make obvious. Styling is pegged to Figma tokens; developers apply the exact tokens from Figma rather than approximating values. Null is banned in favor of undefined, simplifying optional handling. Icon and component imports must use direct imports to enable tree-shaking. The style enforces composition over primitives and discourages raw HTML when Oxygen components exist.</narrative>

<title>Button v2 uses discriminated union for onClick prop (required vs optional)</title>
<subtitle>RegularButtonProps requires onClick; SubmitButtonProps makes it optional; 'handledByParent' literal for trigger patterns</subtitle>
<facts>
<fact>Button.tsx v2 exports discriminated union CommonProps = SubmitButtonProps | RegularButtonProps</fact>
<fact>SubmitButtonProps (type='submit'): onClick optional; form submission handled by form's onSubmit</fact>
<fact>RegularButtonProps (type='button' or default): onClick required; must pass 'handledByParent' string literal when inside trigger (PopoverTrigger, DropdownTrigger)</fact>

<fact>Uses useMousePosition, useDropdownPopover, usePopoverTrigger, useIsOverlay hooks</fact>
<fact>Renders chevron icon when inside DropdownTriggerContext or PopoverTriggerContext</fact>
</facts>
<narrative>Button v2 enforces intentional click handler declaration via a discriminated union pattern. Submit buttons allow onClick to be optional since form submission is the responsibility of the form element. Regular buttons require an explicit onClick handler to prevent silent failures; developers pass the literal 'handledByParent' when the button is used inside a Radix UI trigger component (PopoverTrigger, DropdownTrigger) that injects its own click handler via the asChild pattern. This balances type safety with real-world composition patterns. The button also integrates with dropdown/popover trigger contexts to automatically render a chevron icon that animates based on the parent's open state.</narrative>

</facts>
<narrative>InputText and Select form components implement a hybrid pattern that supports both controlled (value prop) and uncontrolled (internal state) usage. For controlled inputs, charCount is derived from the value prop to avoid state management conflicts in React 19. For uncontrolled inputs, charCount is tracked via local state updated in event handlers. The maxlength constraint automatically sets the field to error state when exceeded, providing immediate validation feedback. The aria-describedby attribute is computed to include hint, message, and character counter messages, providing complete context to assistive technologies.</narrative>

<narrative>Checkbox v2 leverages React Aria hooks to provide accessible keyboard and mouse interaction while maintaining full styling control. The native HTML checkbox input is hidden from view but remains in the DOM for form submission and keyboard operability. A custom styled button element provides the visual checkbox. useFocusRing ensures the focus indicator appears only during keyboard navigation, preventing visual noise from mouse interactions. The component uses boolean values instead of strings, making TypeScript inference cleaner and intent clearer. Controlled updates via prop comparison prevent unnecessary re-renders while keeping internal state in sync with the value prop.</narrative>

<narrative>ReactHookFormField provides a generic wrapper around RHF's Controller to reduce boilerplate when integrating Oxygen components with React Hook Form. It bridges the gap between RHF's event-based onChange (which passes events) and value-based components (which pass values directly, like Checkbox). The wrapper intelligently detects whether the onChange argument has a target property (from a synthetic event) and extracts the value, otherwise passes the value as-is. This allows the same wrapper to work with both InputText (event-based) and Checkbox (boolean-based) without developers needing to write custom Controller render functions.</narrative>

This session is being continued from a previous conversation that ran out of context. The summary below covers the earlier portion of the conversation.
Summary:
1. Primary Request and Intent:
The user requested claude-mem:learn-codebase to explore and document the Oxygen design system monorepo. The intent was to create searchable memory observations that capture the codebase's architecture, patterns, conventions, and key design decisions for future development sessions. This was NOT a code-writing or debugging task, but rather a comprehensive codebase learning and documentation exercise.
-
Key Technical Concepts: - Nx 19.7.3 monorepo with npm workspaces - 10 packages: core (@doctolib/design-system), b2b, b2c, icons, illustrative-icons, tokens, toast, codemods, storybook-config, storybook-hub - React 18/19 with TypeScript 5.5.4 - CSS Modules for styling with 3-tier <REDACTED> (component, semantic, primitive) - Storybook 9.x for component documentation - Vitest for testing with React Testing Library - React Aria for accessibility primitives - Radix UI for headless components - Figma Code Connect for design-to-code mapping - Component lifecycle maturity stages (Draft, Alpha, Beta, Stable) - WCAG 2.2 Level AA accessibility compliance - Discriminated unions for type-safe prop patterns - Controlled/uncontrolled component patterns - Plugin distribution vs internal configuration separation (.claude/ directories)
-
Files and Code Sections:
Documentation Files Read: - /docs/index.md - Documentation index with task-based quick lookup tables - /docs/repo-structure.md - Monorepo structure, 10 packages, key dependencies (React Aria, Radix UI, CSS Modules) - /docs/component-patterns.md - Per-component folder structure (Component.tsx, .module.css, .stories.tsx, .test.tsx, .figma.tsx), file naming conventions, component implementation pattern with forwardRef - /docs/component-lifecycle.md - 4-stage progression (Draft→Alpha→Beta→Stable) with specific promotion requirements and Storybook tags - /docs/code-style.md - Props naming (is, has, should, on, render*), optional props rules, JSDoc discipline, styling with <REDACTED>, icon import patterns, null avoidance - /docs/token-reference.md - 3-tier hierarchy usage rules (component→semantic→primitive for internal; semantic→primitive for external consumers) - /docs/storybook-patterns.md - Default export with satisfies keyword, Overview story pattern, .map() for variant matrices, file scope limits - /docs/testing-patterns.md - Test types (feature, a11y, unit), test-helper queries (buildRoleQueries, buildDSComponentQueries), deduplication rules - /docs/a11y-patterns.md - WCAG 2.2 AA compliance, ARIA principles, prohibited patterns (outline:none, explicit tabindex), keyboard navigation requirements - /docs/component-index-core.md - Core package catalog: 300+ components across 8 categories (actions, collection, dataDisplay, feedbacks, forms, layout, navigation, overlays) - /docs/component-index-b2b.md - B2B variant components (adds DataGrid, Filters) - /docs/component-index-b2c.md - B2C variant components
Source Code Files Read (40+ files demonstrating patterns):
Actions Category: - Button/v2/Button.tsx - Discriminated union for onClick prop (required vs optional based on type='submit'), loading state with aria-live announcer, chevron icon when in dropdown/popover context, handles 'handledByParent' literal for trigger patterns - IconButton/v2/IconButton.tsx - Uses useMousePosition and React Aria hooks, shares Button styling, wraps in Tooltip, supports both deprecated icon name string and direct IconComponent - Switch.tsx - Partial reset pattern for controlled updates (preserves CSS transitions), aria-pressed button + visually hidden checkbox - Dropdown.tsx - Compound component (Item, Checkbox, Button, Link, Icon, etc), uses non-interactive span wrapper for Checkbox to avoi …(truncated, 8358 more chars)

I'm continuing from the comprehensive codebase learning session. The background agent tasks have completed reads of additional source files. I'll now document these patterns and findings through memory observations to capture the architectural insights.
<observation> Advanced Form Patterns & Accessibility
RadioGroup demonstrates sophisticated field composition: - Fieldset-based with computed aria-labelledby across label, message, and hint - Auto-focus pattern via _shouldAutoFocus prop + computed autoFocusIndex - Controlled/uncontrolled state via inputValue + previousValue sync pattern - Discriminated union for variant/orientation/size combinations (default|stacked|card × horizontal|vertical × medium|large) - LabelWrapper helper for conditional ScreenReaderOnly wrapping
ComboBox shows React Aria patterns at scale: - Discriminated union for uiStyle: default has hint/contextualPopover; floating doesn't - ComboBoxValue type: { type: 'option'|'custom', value } | undefined for distinction - Mobile detection via useMediaQuery switches to MobileComboBox - forbiddenContent validation checks for interactive children (buttons, inputs) - Option flattening utility (flatMapOptions, isOptionGroup) for hierarchy handling
InputDate/Textarea mirror InputText structure: - Floating label via useFloatingLabelField hook with isEmpty tracking - Textarea: auto-resize via hasAutoResize check + charCount validation (forced error state if exceeds maxlength) - Both use discriminated union for uiStyle (default with hint vs floating without contextualPopover)
Toggle: Controlled/uncontrolled via checked prop, supports label positioning (left/right), color variants (blue|green), and platform-aware rendering via usePlatform.
Slider (@beta): React Aria slider with value hints array (2-3 elements for min/mid/max annotations), uses previousValueProp sync pattern during controlled updates, SliderOutput for display. </observation>
<observation> Navigation & Overlay Component Strategies
Pagination: - Controlled currentPage with nbDoublePagesDisplayed for ellipsis math - ButtonBase approach with PaginationButton/PageNumberButton/Ellipsis subcomponents - Optional isLoading skeleton state, showInfos toggle, paginationDisabled gate
SidebarMenu: - Compound component with SidebarMenu + SidebarMenuItem - React Router Link integration (to, href, target support) - Optional icon + mandatory tooltip with placement control - TappableWithForwardedRef for touch handling - titleUiStyle prop for typography override
Drawer (MUI SwipeableDrawer-based): - Position variants, size prop, blocking disables swipe-down + escape - DrawerBody/DrawerFooter subcomponents, DrawerListAction/DrawerBodyIconActionGroup for specialized content - Responsive dvh units for mobile height calculation
ContextualPopover: - Platform-aware: Popover on desktop, Modal on mobile - Variant discrimination (help|info) with conditional icon (regular/circle-question vs regular/square-info) - Trigger via internal IconButton
AlphaSidePanel (MUI Modal-based): - Size variants: small|medium|large - Footer optional via SidePanelFooter subcomponent - Auto-enriches AlphaSidePanelHeader children with onClose, size, and titleId props
Backdrop: - CSSTransition animation wrapper, muted variant with optional SpinnerLoader (500ms delay) - uiStyle discrimination (dark|light) </observation>
<observation> Core Flex/Layout & Testing Utilities
Flex (private primitive): - Emotion's ClassNames for dynamic CSS + semantic element polymorphism - ALIGN_ITEMS: baseline|normal|start|center|end|stretch - JUSTIFY_CONTENT: normal|start|center|end|space-between|space-around|space-evenly - Direction + hasWrap + min/max width/height constraints - CSS custom property --oxygen-PRIVATE-columns-gap-x for computed column gap - Underlying both VStack and HStack
useAriaLiveAnnouncer: Thin @react-aria/live-announcer wrapper returning { announceInLiveRegion(assertiveness, message) }
getIconByNameOrComponent: Polymorphic helper accepting IconName string or DesignSystemIconComponent, filters undefined props for custom component rendering
Testing Utilities: - buildRoleQueries(componentName, role) returns get/query/find* getters with role-based matching - buildDSComponentQueries(componentName, isMatching?) uses data-design-system-component attribute selector - nameQueries(componentName, queries) renames generic locators to component-specific (e.g., getButton → getCard) - refineQueries(queries, refiner) wraps existing locators with post-filter predicates - Optional container parameter overloading for scoped queries - hasRole(role, element) / isDSComponent(componentName, element) predicates </observation>
<observation> Data Display Complexity: Accordion, Pill, Card, Avatar Patterns
Accordion: - Context-based state management via AccordionContext (isAccordionItemOpen, open/closeAccordionItem callbacks) - Three exports: Accordion (provider), AccordionItem (context-connected), StatelessAccordionItem (fully controlled) - allowMultipleExpand toggles single vs multi-select mode via setOpenItems strategy - Discriminated union: titleUiStyle 'Body/S/Bold' renders <Paragraph>, others render <Heading level> - AccordionTitleColor map converts deprecated text color tokens to heading-safe ones (some map to undefined) - useId for button/content aria-controls/aria-labelledby linking - arrowPosition prop (left|right) controls chevron placement
Pill: - Complex discriminated union for image vs illustration with child content validation - validatePillUsage in dev mode checks for forbidden interactive content (buttons, inputs) - PillList, PillLabel, Pill subcomponents - Size variants: xsmall|small|medium - Color variants: 9 options (error/neutral/primary/purple/success/teal/warning/white/yellow with -020 suffix)
Card v2: - Three variants: CardElevated, CardOutlined, CardSolid (thin wrappers around private Card) - CommonProps shared type definition in private/Card.tsx - className + data-design-system-component passthrough pattern
AvatarGroup: - DEFAULT_MAX_AVATARS = 4, clones Avatar children with bordered=true - renderRemaining helper for "+N" overflow indicator - Orientation: horizontal|vertical </observation>
<observation> Table, Pill Content Validation & Avatar Color Computation
Table: - Native <table> props spread via ComponentPropsWithoutRef<'table'> - fixedLayout boolean, size variants (xsmall|small|medium), className override - loading prop switches to TableSkeletonLoader rendering mode - skeletonLoaderProps passthrough for loader customization - Simple wrapper component with semantic HTML preservation
AvatarGroup Detail: - Uses Avatar's color computation (based on id/text/icon hash, 16 color options) - bordered=true clone forces bordered rendering in group context - Supports rightIcon on avatars - Status indicators inherited from Avatar
Pill Detail: - Image variant discriminated via img prop (ReactNode image + link support) - Illustration variant via illustration prop (ReactNode) - Child content (PillLabel) must not contain interactive elements (validated via containsForbiddenInteractive) - deprecated-pill-interface escape hatch for legacy child-based API - Badge integration for decorative counts - SpinnerLoader for loading state inside Pill </observation>
The comprehensive exploration of the Oxygen codebase is now complete with detailed documentation of all major architectural patterns, component structures, accessibility implementations, and development conventions captured for future reference.

<observation> Feedback Component Patterns: EmptyState, SpinnerLoader, ProgressBar
EmptyState:
- Discriminated union via image vs illustration props (mutually exclusive using never type)
- Image variant: accepts image string, optional imageAlt, size (32|64|80|120|160|240)
- Illustration variant: accepts IllustrativeIconProps object, no imageAlt or size
- Optional title with configurable titleLevel (h1-h6), optional children content
- primaryAction/secondaryAction of type { text, walkmeid?, ...ButtonProps }
- loading boolean triggers rendering alongside SpinnerLoader + "processing..." message
- Secondary action defaults to uiStyle='small-primary'
- Center-aligned flex column layout wrapping content
SpinnerLoader: - SVG-based circular progress indicator with animated stroke - SPINNER_SIZES: { xsmall: 8, small: 12, medium: 16, large: 24 } - Color variants: white|blue|neutral|danger mapped via CSS classes dl-path-${color} - Size-dependent stroke classes: dl-path-${size} - Rendered as role='progressbar' with aria-valuemin/valuemax (0/100) - Background circle + animated foreground circle composition - Default size='large', color='blue'
ProgressBar: - Exports utility function toPercent(current, total) with comprehensive guards (negative, NaN, Infinity, zero-division) - Label display: configurable via hideLabel prop - Value display: optional via showValue, format toggleable (percentage vs fraction) via isFormatPercentage - aria-valuenow/valuemin/valuemax for accessibility - Optional hasRadius border-radius styling - ScreenReaderOnly announcement via Translate component for sr-only context - Fill div width calculated as ${percentageValue}% </observation>
<observation> Alert Component Architecture: Banner, Card, Hint Variants
All three (AlertBanner, AlertCard, AlertHint) are thin wrappers over private _Alert component with discriminated variant behavior:
AlertBanner: - variant='banner' (width-filling) - align defaults to 'center' (can be overridden) - size defaults to 'medium', excludes 'xsmall' - Omits isFittingContent, variant, size from public props
AlertCard: - variant='card' (more prominent, self-contained) - No align prop (card-specific centering) - size defaults to 'medium', excludes 'xsmall' - Omits align, variant, size from public props
AlertHint: - variant='hint' (no background, stackable) - onClose always undefined (non-closeable) - size defaults to 'small', excludes 'medium' - Omits isFittingContent, align, variant, size, onClose from public props
Pattern: Each variant enforces specific size ranges (AlertBanner/Card: medium-large; AlertHint: small/xsmall), and feature availability (only Banner+Card support close, only Card removes align control). </observation>
<observation> Navigation Controls: SegmentedControl Generic Implementation & Stepper States
SegmentedControl: - Generic type parameter ComponentProps extends RefAttributes<HTMLAnchorElement> for router-agnostic linking - Discriminated union: ButtonProps (component?: 'button', options: Option[]) vs LinkProps (component: RouterLink, options: AnchorOption[]) - isButtonItem type guard differentiates render path - Internally controlled state via useState synced with external value via useEffect - useFocusVisible hook for keyboard-focus styling (isFocusVisible class toggle) - onChange callback fires on click, updates internal state, then conditional onChange call - Renders as <ul> with <li> wrappers per option, conditionally renders <SegmentedControlButtonItem> or <SegmentedControlAnchorItem> - walkmeId optional prop for analytics
Stepper: - Exports three: Stepper container, Step individual step, StepperStep type, computeStepState utility - computeStepState(activeStep, stepNumber) returns 'done'|'active'|'inactive' based on comparison - Step component: - Renders as <button> when onClick provided, else <div> - Done state: Icon (check) with backgroundClassName + backgroundColor - Active/inactive: Badge with uiStyle='info'|'neutral' - labelColor conditional: 'shared/text/minorText/weak' for inactive, default for active/done - totalSteps triggers ScreenReaderOnly with i18n Translate announcement - Stepper container: - Maps steps array, renders Step + separator Icon (solid/chevron-right) between steps - hideLabelOnMobile + isOnMobile combination for responsive label hiding - onClickStep callback passes full StepperStep object (not just index) </observation>
<observation> Utility & Design System Patterns Summary
Accessibility First: - role='progressbar' for SpinnerLoader, ProgressBar with aria-valuenow/valuemin/valuemax - aria-current, aria-label, aria-expanded, aria-controls used throughout - ScreenReaderOnly wrapper for sr-only content, optional hasReadingPause prop on Translate - Discriminated unions ensure mutually exclusive prop sets (can't provide both image and illustration)
Internationalization: - useTranslations hook for runtime message lookup - Translate component for i18n key + params - Keys follow pattern: oxygen.feedback.${component} / oxygen.indicator.${component}
Styling Patterns: - CSS Modules primary (.module.scss / .module.css) - Emotion ClassNames for dynamic utility class composition - Tailwind size classes (w-${size}, h-${size}) computed dynamically - Custom properties: --oxygen-PRIVATE-* for internal token use
Component Organization: - Private/_Component.tsx for shared implementations - Public wrapper components enforce variant constraints via type discrimination - forwardRef for imperative handle access where needed (Accordion, some forms) - displayName for debugging - data-design-system-component attribute for test query building </observation>
The comprehensive exploration of the Oxygen design system is now complete. All major component categories have been documented: actions, forms, layout, data display, navigation, overlays, feedbacks, and indicators, along with core utilities, hooks, and testing helpers. The codebase demonstrates sophisticated architectural patterns including discriminated unions for type safety, private component composition for code reuse, and consistent accessibility/internationalization practices across all 300+ components.

<observation> Internationalization System Implementation
i18n Architecture (i18n/i18n.ts): - DEFAULT_LOCALE = 'EN', supported: EN, FR, DE, IT - Dynamic KEYS object auto-generated from EN translations to avoid maintenance burden - Type-safe translation with TranslationKey type from i18nTypes - getByLocale(locale, translation) — simple key lookup with EN fallback, normalizes locale to uppercase, no parameterization - addParameters(translation, params) — replaces {key} placeholders with values via regex - translate({ locale, key, params? }) — single key translation with optional parameterization - translateAll({ locale, translations }) — batch translation helper accepting both string keys and {key, params} objects - Special case: locale === 'KEYS' returns the translation key itself (useful for debugging/testing) - Type-safe params via TranslationParameters<Key> mapped type
Usage Pattern: - Components use useTranslations hook (simple wrapper returning computed i18n object) - Translate component for React rendering with i18nKey + params - ScreenReaderOnly + Translate combination for sr-only content </observation>
<observation> Responsive Layout & Platform Detection Hooks
useMediaQuery Hook: - SM_SIZE breakpoint = 768px - matches() helper: typeof window check for SSR safety (returns false if no window) - useMediaQuery returns { isSmallScreen } boolean - useEffect syncs SSR/client mismatch: setIsSmallScreen(mediaQuery.matches) on mount - window.matchMedia('(max-width: 767px)') listener for real-time updates - Cleanup unsubscribes from MediaQueryList change events
usePlatform Hook: - Reads window.platforms object (monolith integration) - Detects: isOnMobile (variant === 'mobile'), isOnSafari (UA check avoiding Chrome), isIosApp (reactNative + ios flags) - hasSafeAreaView() checks businessUnit === 'doctor' && version >= '3.1.4' - FIXME comments indicate desire to pass platforms explicitly rather than via global window
Pattern: Global state via window object (legacy monolith architecture) awaiting refactoring to prop-based injection </observation>
<observation> Layout Composition & Overlay Patterns
useIsOverlay Hook: - Simple boolean-to-props converter: returns { 'data-oxygen-is-overlay': true, className } or {} - Makes element clickable area expand to whole container (Card.isOverlay effect) - Used internally via useIsOverlayContainer (companion hook) - Data attribute enables styling hooks (e.g., parent hover/active styles)
tokensHelper Utility: - GAPS and PADDINGS exported as const arrays extracted from token design system - Gap type supports string (shorthand) or WithDirections (x/y) polymorphism - Padding type extends to 4-direction support (top/left/right/bottom + x/y) - getGapValues/getPaddingValues normalize polymorphic input to directional object - Default parameter fallback for missing directions (e.g., gap.x ?? defaultGap) - Token lookup via TOKENS.web['oxygen-scale'].semantic.[gap|padding]
Private Card Component: - Shared implementation for CardElevated/CardOutlined/CardSolid variants - displaySizes: xsmall|small|medium|large|xlarge (controls padding + radius) - showOverflow boolean for combobox/select overflow handling - useIsOverlayContainer integration for overlay behavior - ClassName pattern: variants pass custom className string applied alongside display-{size} </observation>
<observation> Text Rendering & Color Token Mapping
_Text Private Component: - Polymorphic: component prop (h1-h6, p, span, strong) - Color mapping: deprecation bridge from old text colors to new semantic <REDACTED> - TEXT_COLORS map: shared/text/{headerText|bodyText|minorText}/{inverted|weak|default|weaker} - TEXT_FONTS map: Body/Title × size × weight (XS|S|M|L|XL|XXL|XXXL × Regular|Bold) - Transform variants: capitalize|lowercase|uppercase|upperFirst (CSS text-transform) - Inline vs block via isBlock prop (controls display CSS) - _id, _lang, _tabIndex props for aria-labelledby linking + language markup + focus management - Style spread: { color, font } applied directly (computed from token maps)

<observation> Additional Component Patterns: Text, Carousel, OverlayContainer
Text Component (Deprecated): - Two-tier typography system: old (DEPRECATED_*) and modern (tag-weight-size) - TextColor union: error/neutral/primary/success/warning variants with intensity levels (090–160) - TextUiStyle discrimination: parseUiStyle(uiStyle) extracts tag, size, weight from hyphenated string - DEFAULT_COMPONENT_BY_UI_STYLE mapping for semantic element selection (h1-h6 defaults) - Layout props: block, align, ellipsis (⚠️ deprecated), lineClamp, whiteSpace, transform - Backward compatibility: deprecated text color tokens bridged to new semantic color system - renderTailwindStyles integration for customStyle prop - @deprecated marker directs users to Paragraph/Heading/Span semantic alternatives
Carousel Component: - Generic type parameter enforces tuple of React.ReactElement slides - IndexOfArray<Slides> typed indices prevent out-of-range selections - transitionDelay 500ms for smooth CSS transitions - loop prop enables infinite/circular navigation - Touch event handling: tracks deltaX/deltaY to distinguish swipe (>50px) from vertical scroll - aria-labelledby linking from buttons to slide announcements - useAriaLiveAnnouncer for "slide X of Y" polite announcements - PaginationDots subcomponent for dot navigation - Color discrimination: 'default' vs 'inverted' variant support - Focus management: toggles focus between next/prev buttons at boundaries
OverlayContainer (@beta): - Positioned ancestor for constraining overlay bounds (internal implementation detail) - Polymorphic component prop: div | span - Variant discrimination: 'brand' (default) for styling hook - useIsOverlayContainer hook encapsulates positioning CSS + data attribute - Enables child IconButton.isOverlay to determine overlay surface area </observation>
<observation> Advanced Card & Collapsible Patterns
Divider Component: - Native <hr> semantic element with aria-hidden by default - UiStyle variants: white|neutral-030|neutral-130|warning-090 - isVertical boolean for vertical orientation - _removeSemantic flag for non-semantic use (e.g., inside listbox) — toggles role='presentation' and aria-hidden - margin prop adds spacing top/bottom - HTMLProps<HTMLHRElement> spread for full HTML compatibility
CardCollapsible Component (407 lines): - Discriminated union for actions: PopoverContentAction|OverlayAction|ActionButtonProps - State tracking: collapsed (controlled/uncontrolled), scrollState (top/bottom shadow detection) - size variants: xsmall|small|medium|large map to title component (Paragraph vs Heading) - headerClassname supports custom styling - divider prop toggles separator between header and body - maxHeight optional constraint + scrollable overflow - Action system: popover-based (PopoverContent render function), tooltip overlay, or simple button - onCollapseToggle callback on state change - padding prop controls spacing around content
CardCollapsible Action Patterns: - ActionButton helper renders either Icon via IconButton or text via Button - PopoverContentAction: passes (onClose) callback to render function for programmatic dismiss - OverlayAction: wraps with Tooltip (placement/overlayClassName) - Simple ActionButtonProps: direct onClick callback - All action types support walkmeId for analytics
CardCollapsible Styling: - Full height flex layout with VStack composition - headerExpandedPadding / headerCollapsedPadding discriminated via collapsed state - Scrollable body with ResizeObserver + scroll event listener for shadow detection - hasTop/hasBottom shadow classes toggle via scrollState CSS custom properties </observation>
<observation> Form Input & Dropdown Patterns: Color, Number, Pin, Dropdown
InputColor v2: - Discriminated union: Default (uiStyle='default', contextualPopover, hint) vs Floating (uiStyle='floating') - useFloatingLabelField hook for label animation + isEmpty tracking - _RawInputColor wrapper for raw input primitive - allowCustomColors & colors options passed through - isTransparent boolean for blended color backgrounds
InputNumber: - Similar structure to InputColor (Default | Floating discrimination) - isSpinButton boolean toggles between text input and spinner buttons (up/down) - min/max/step HTMLInput props spread through - inputMode prop (numeric, decimal) for mobile keyboard hint - useFloatingLabelField for label animation
PinInput (@beta): - Uses InputFieldSet (not InputField) as wrapper - pinLength specifies number of boxes - isMaskable boolean for obscured input (password-style) - type prop for input variant
DropdownTrigger (Router-Agnostic Pattern): - Radix UI Popover.Root wrapper with internal state management - Discriminated union: anchor tag (default) vs React Router Link component - triggerButton prop: HOC function receiving { onClick, aria-expanded } props - Sanitized child pattern: cloneElement to preserve existing onClick without duplication - closeOnClick & closeOnInteractOutside control dismissal behavior - defaultIsOpen boolean with accessibility warning (auto-open is disorienting) - Portal support via portalContainer prop - popoverType aria attribute for accessibility ("menu"|"listbox"|"tree"|"grid"|"dialog") - position/align props control Popover.Content placement - children can be static or render function receiving { onClose } callback </thinking>
<observation> Router-Agnostic Link & Template Component Patterns
_PrivateLink (Router-Agnostic): - Discriminated union: anchor tag (component='a' | omitted) vs React Router Link - Polymorphic component prop for framework independence - ReactAriaLink wrapper for anchor tags (from react-aria-components) - opensInNewTab boolean auto-computes rel='noopener noreferrer' for security - _dangerousOnClick for internal migration (legacy onClick handling) - Component-based routing: accepts any Router-compatible component (React Router, TanStack Router, etc.) - Ref forwarding to underlying <a> or custom component - Minimal public API; router details deferred to component prop
FocusPanel Template (B2B, @alpha): - Patient file sidebar panel (non-modal, persistent, allows background interaction) - Header: title, optional stepBack button, headerAction icon, close button - Body: scrollable content with top/bottom shadow gradient detection - Footer: cancel, alternative, confirm action buttons - FocusPanelAction: icon + label + onClick - FocusPanelConfirmAction: supports formId for form submission, isLoading, isDisabled, loadingLabel - FocusPanelAlternativeAction: secondary action with loading state - FocusPanelStepBack: back navigation with tooltip - ResizeObserver tracks body scroll state for shadow display - VStack container for layout (flex column, full height) - Keyboard tab handling: handleTabExitGrid shifts focus out of panel to next tabbable element
FocusPanel CSS Module:
- .focusPanel — full height/width, border-radius, semantic color background
- .panelHeader — padding, z-index: 10
- .panelBodyWrapper — ::before/after pseudo-elements with gradient shadows (opacity animates via hasTop/hasBottom classes)
- .panelBody — flex: 1, overflow-y: auto, tabIndex={0} for keyboard scrolling
- .panelFooter — z-index: 10, padding

This session is being continued from a previous conversation that ran out of context. The summary below covers the earlier portion of the conversation.
Summary:
1. Primary Request and Intent:
The user requested claude-mem:learn-codebase to perform a comprehensive exploration and documentation of the Oxygen design system monorepo. The explicit intent was to "create searchable memory observations that capture the codebase's architecture, patterns, conventions, and key design decisions for future development sessions." This was explicitly NOT a code-writing or debugging task, but rather a pure learning and documentation exercise to prepare for future development work without losing architectural context.
-
Key Technical Concepts: - Nx 19.7.3 monorepo with npm workspaces (10 packages) - React 18/19 with TypeScript 5.5.4 - CSS Modules for styling with 3-tier <REDACTED> (component → semantic → primitive) - Storybook 9.x for component documentation - Vitest and React Testing Library for testing - React Aria for accessibility primitives - Radix UI for headless components - Figma Code Connect for design-to-code mapping - Component lifecycle maturity stages (Draft, Alpha, Beta, Stable) - WCAG 2.2 Level AA accessibility compliance - Discriminated unions for type-safe prop patterns - Controlled/uncontrolled component patterns - Plugin distribution vs internal configuration separation - React hook patterns (useRef, useState, useEffect, useCallback, useId) - forwardRef and useImperativeHandle for imperative handles - Context-based state management - Platform detection (mobile, iOS, Safari) - Responsive design via media queries and hooks - Floating label patterns with animated transitions - Compound components and context-based coordination - Private component composition for code reuse
-
Files and Code Sections: The exploration covered 40+ source files across the monorepo:
Documentation Files (Read for architectural understanding): - /docs/index.md - Task-based lookup tables - /docs/repo-structure.md - Monorepo structure and dependencies - /docs/component-patterns.md - Per-component folder structure and naming conventions - /docs/component-lifecycle.md - 4-stage progression with promotion requirements - /docs/code-style.md - Props naming conventions, JSDoc discipline, styling hierarchy - /docs/token-reference.md - 3-tier token usage rules - /docs/storybook-patterns.md - Story structure and variant matrices - /docs/testing-patterns.md - Test types and deduplication rules - /docs/a11y-patterns.md - WCAG 2.2 AA compliance and ARIA principles - /docs/component-index-*.md - Catalog of 300+ components across categories
Action Components: - Button/v2/Button.tsx - Discriminated union for onClick prop, loading state with aria-live announcer, chevron icon conditional rendering, handledByParent literal handling - IconButton/v2/IconButton.tsx - React Aria hooks integration, shared Button styling, Tooltip wrapper - Switch.tsx - Partial reset pattern for controlled updates, aria-pressed button + visually hidden checkbox - Dropdown.tsx - Compound component with non-interactive span wrapper for nested interactions - ButtonFloating.tsx - Wrapper with hardcoded size/uiStyle, ScreenReaderOnly label
Form Components: - InputText.tsx / RawInputText.tsx - Hybrid controlled/uncontrolled via charCount, clear button for search type, imperativeHandle - Select.tsx - Mirrors InputText, floating label pattern, discriminated union uiStyle - Checkbox/v2/Checkbox.tsx - React Aria useFocusRing, useVisuallyHidden, controlled boolean value - RadioGroup.tsx - Fieldset-based with legend, auto-focus pattern, orientation/size/variant discrimination - InputDate.tsx - Similar to InputText with floating label, date-specific props - Textarea.tsx - Auto-resize support, row control, charCount validation - Slider.tsx - Reac …(truncated, 13389 more chars)

The comprehensive codebase exploration has been fully documented. All background tasks have completed, capturing:
FocusPanel Template (B2B): - Full component hierarchy (FocusPanel → Header/Body/Footer subcomponents) - Persistent, non-blocking panel for patient file sidebar - Scroll shadow detection with ResizeObserver + ::before/::after gradients - Discriminated action types (stepBack, headerAction, confirmAction, cancelAction, alternativeAction) - Keyboard scrollability via tabIndex={0}
.claude Rules & Governance:
- composition-over-css.md — Always use layout components (HStack/VStack/Columns) instead of raw flexbox/grid
- verify-component-api.md — Mandatory: read component props from source before using; respect package boundaries (@doctolib/design-system-b2b in b2b files)
- poc-exception.md — POC code can skip isolation/style rules but must pass TS/lint
- potential-improvements.md — Recurring friction points (prop guessing, unnecessary refactoring, over-engineering state) with proposed fixes
The codebase is now fully documented and ready for any development work. You have comprehensive knowledge of: - All 40+ key component implementations - Architecture and monorepo structure - Design token system and accessibility patterns - Testing strategies and Storybook setup - Code quality rules and composition patterns - Governance and contribution workflows

Comprehensive documentation of Oxygen development infrastructure continues:
Code Quality & Review Agents:
- .claude/agents/review-code-quality.md — Internal agent reviewing Oxygen component source code against project quality principles
- agents/review-code-quality.md — Consumer-facing agent reviewing code that uses Oxygen components, checking API correctness, <REDACTED>, composition patterns
- agents/migrate-deprecated-components.md — Migration specialist for deprecation/v1→v2 migrations
AI-Assisted Development Guardrails (docs/ai-comprehension.md):
- Active Inquiry — Present multiple valid approaches before choosing one
- Implicit Decision Audit — Surface non-obvious decisions (edge cases, defaults, error handling, a11y, library deviations)
- Mandatory Change Intent — State what will change and why before writing code
- Anti-Delegation — Push back on vague prompts; require clear scope before implementing
- Comprehension Checkpoint — Verify humans can own/modify code independently
- Blast Radius Control — Large PRs degrade understanding; decompose into stacked PRs with foundational root → dependent children
Review Checklist for Consumer Code:
1. TailwindStyle — keep customStyle minimal, use component props instead
2. Component Overrides — no className/style, don't fight layout intent
3. <REDACTED> — semantic > component > primitive
4. Component API — read source, respect v2 migrations, include a11y props
5. Composition — prefer HStack/VStack/Columns over raw CSS
Available Skills: 17 in .claude/skills/ (ask-design-system, audit-a11y, audit-code-style, ds-duty, review-pr, etc.) + 10 in skills/ (build-forms, migrate-design-system, review-code, etc.)
You now have complete documentation of: - Component implementations (60+) - Architecture & infrastructure - Design tokens & accessibility - Development workflows & quality standards - Code review processes & guardrails - Available tools & agents

Any other root tag is a protocol violation.
PROGRESS SUMMARY CHECKPOINT
Write progress notes of what was done, what was learned, and what's next. This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary. Write "next_steps" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.
Claude's Full Response to User:
The observation_add and memory_add tools both require CLAUDE_MEM_RUNTIME=server-beta, but this session runs in worker mode. However, the system context already shows 22 observations (1443–1464) were automatically persisted from the prior session's work — covering the key architectural facts: Nx monorepo structure, component lifecycle, <REDACTED>, component APIs, patterns, and testing conventions.
The /claude-mem:learn-codebase skill is complete. The cognitive cache is built and queryable via mem-search. The codebase knowledge captured includes:
- Monorepo structure (8 packages, Nx 19.7.3, Storybook ports)
- Component lifecycle (Alpha → Beta → Stable promotion checklists)
- Token system (3-tier hierarchy, mandatory grep-before-use rule)
- CSS patterns (modules, nesting rules, no raw flex/grid)
- All major component APIs: actions, layout, forms, overlays, navigation, feedbacks, dataDisplay
- B2B-specific components: DataGrid, Filters, FocusPanel
- Testing patterns, a11y rules, i18n providers, toast system, codemods
- Claude rules, openspec workflow, plugin review checklist
Respond in this XML format: <summary> <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request> <investigated>[What has been explored so far? What was examined?]</investigated> <learned>[What have you learned about how things work?]</learned> <completed>[What work has been completed so far? What has shipped or changed?]</completed> <next_steps>[What are you actively working on or planning to work on next in this session?]</next_steps> <notes>[Additional insights or observations about the current progress]</notes> </summary>
REMINDER: Your response MUST use <summary> as the root tag, NOT <observation>. IMPORTANT! DO NOT do any work right now other than generating this next PROGRESS SUMMARY - and remember that you are a memory agent designed to summarize a DIFFERENT claude code session, not this one.
Never reference yourself or your own actions. Do not output anything other than the summary content formatted in the XML structure above. All other output is ignored by the system, and the system has been designed to be smart about token usage. Please spend your tokens wisely on useful summary content.
Thank you, this summary will be very useful for keeping track of our progress!

<summary>
<request>Comprehensive codebase exploration and documentation of the Oxygen design system monorepo via claude-mem:learn-codebase skill, with continuation from prior context-limited session.</request>
<investigated>All 10 Oxygen packages (core, b2b, b2c, icons, illustrative-icons, toast, codemods, b2b templates, templates, a11y-checker) across 80+ components. Architecture: Nx 19.7.3 monorepo with npm workspaces, React 18/19, TypeScript 5.5.4, CSS Modules with 3-tier token system. Key areas examined: component lifecycle (Alpha→Beta→Stable), <REDACTED> (primitive→semantic→component), controlled/uncontrolled patterns, discriminated unions, compound components, Storybook 9.x, Vitest testing, Figma Code Connect integration, AST codemods for migrations.</investigated>
<learned>Oxygen architecture and governance: Nx caching & dependency ordering, <REDACTED> rule, component v1/v2 versioning strategy with gradual migration. Patterns: React Aria hooks + Radix primitives for a11y, floating label animations, shadow DOM manipulation (EmojiPicker), generic type inference for filters, context-based compound coordination, platform detection for mobile overlays. B2B specializations: DataGrid with custom sorting/column mapping, Filters with discriminated union types, FocusPanel persistent sidebar. Form infrastructure: controlled/uncontrolled sync via refs, aria-describedby composition, InputLabel legend/label dual modes, InputMessage state icons. Testing: interaction stories (Storybook), test-helpers pattern (no raw getByRole), a11y checklist. Migrations: 14 codemods handling Alert split (Banner/Card/Hint), Toggle→Switch, Icon API migration.</learned>
<completed>Systematic read of 100+ source files across all packages: components (Icon, Button, Modal/Drawer/Popover, Table variants, Toast, EmojiPicker, Picture, CheckboxGroup, Filters, DataGrid, CardCollapsible, InputDateNoPicker), utilities (privacy helpers, omit, useOutsideClickHandler, useDebounce, useIsOverlay), private forms infrastructure (Field, Option, aria, InputLabel, InputMessage, CardSelectable), codemods (Alert.migration, replace-alert.ts, replace-toggle.ts, component utilities), configuration (eslint.config.js, tsconfig.json, nx.json, vitest.config.ts), and plugin documentation (plugin.json, skills, agents, package conventions). All 22 observations from prior session automatically persisted to cognitive cache.</completed>
<next_steps>Awaiting explicit development task request from user. Ready to assist with: building new components, fixing bugs, refactoring, migrating deprecated components, reviewing code quality, writing tests, or implementing design handoffs. No active work in progress—session is idle pending user instruction.</next_steps>
<notes>Cognitive cache fully populated with architectural context, component APIs, patterns, tooling, and governance rules. Memory persistence system operational (observations 1443–1464 from prior session + ToolSearch queries confirm query infrastructure active). Session demonstrates successful continuation with full context retention across context boundaries. User can now work on any Oxygen feature without architectural knowledge loss.</notes>
