Agent-Native Toolkit
Use this skill when deciding whether app chrome, settings, collaboration,
sharing, navigation, organization, setup, history, comments, or agent UX should
be built app-locally or moved into reusable framework/toolkit pieces.
Core Rule
Apps own domain models, domain actions, and product-specific workflows. The
framework and @agent-native/toolkit own repeated workspace behavior users
expect to work the same everywhere.
Move behavior into shared toolkit primitives when it is:
- workspace-wide, such as settings, nav, search, org membership, or setup
- agent-visible, such as context, actions, run progress, or proof-of-done
- governed, such as secrets, permissions, sharing, audit, or billing
- repeated by two or more apps
- not tied to one domain model
Keep behavior app-local when the abstraction would hide important domain
language or make a simple app-specific workflow harder to understand.
Discover Before Building
Before creating an app-local version of repeated workspace or agent UI:
- Check the reusable kits below and the installed package documentation.
- Search installed public components and source with
docs-search and
source-search.
- Run
agent-native eject --list to see the version-matched units published
by the packages installed in this app.
- Read
customizing-agent-native and configure, compose, or eject the
smallest unit instead of recreating shared behavior from memory.
Use public package exports at runtime. Published source and ejection manifests
are discovery and ownership-transfer mechanisms, not private runtime APIs.
Design-System Boundary
Every app keeps an explicit design-system seam in app/design-system.ts using
defineDesignSystem from @agent-native/toolkit/design-system, and supplies it
to ToolkitProvider. The semantic contract contains:
- nine leaf components:
ActionButton, IconButton, TextField, TextArea,
Spinner, Skeleton, Status, Surface, and Avatar
- eight behavior components:
Tooltip, Menu, Popover, Dialog, Picker,
Checkbox, Switch, and Tabs
These are semantic contracts, not styling contracts. An adapter may use
Tailwind/shadcn, MUI-style theme providers, React Aria, CSS modules, CSS-in-JS,
or another React design system. Do not assume CVA, utility classes, or even a
className; behavior adapters may supply their overlay and focus
implementation wholesale while honoring portal, focus-restoration, keyboard,
dismissal, ARIA, and z-index interoperability.
Pages, routes, and domain components import ordinary controls through the app's
local adapter layer, usually @/components/ui/*. They must not import
@agent-native/toolkit/ui/* directly. Toolkit feature exports are still the
right home for shared workspace behavior; their presentation flows through the
registered semantic components, feature controller, and product-level slots.
Customer adapter packages are normal npm packages imported explicitly by the
app. Never auto-detect them or load React components from JSON. Run the adapter
against @agent-native/toolkit/conformance in customer CI before adopting it.
Settings Direction
Durable settings belong in the Settings app or a registered settings route. The
agent sidebar should not become a second settings app. It can show contextual
quick controls and deep links such as:
/settings/ai
/settings/connections
/settings/secrets
/settings/usage
/settings/apps/:appId
The shared Account section is the canonical profile surface at
/settings#account. It owns the editable display name and existing avatar
control through the authenticated get-user-profile and update-user-profile
actions. Shared workspace chrome such as OrgSwitcher should link to this
surface rather than creating an app-local profile page.
When adding a new API key, OAuth grant, provider connection, model selector, app
preference, notification preference, or usage/billing surface, register it as a
settings tab or app settings panel first. Only add sidebar UI when it is needed
in the moment of agent use.
Reusable Kits
- Settings kit: a searchable settings page with account, workspace, AI
models, LLM keys, connections, secrets, usage, notifications, changelog, and
app-specific panels. Search is on by default; register a
SettingsSearchEntry
per control so users find settings by name across tabs.
- Collaboration kit: Yjs docs, presence, agent presence, live cursors,
remote selections, recent edit highlights, real-time sync indicators, and
undo/redo grouping.
- Sharing kit: private/workspace/org/public-link access, invites, roles,
expirations, agent-readable links, and resource registration.
- Navigation and command kit: app shell, side nav, breadcrumbs, app switcher,
command palette entries, recent resources, pinned resources, and global search.
- Organization kit: folders, tags, favorites, archive, trash, ownership,
membership, and common resource metadata.
- Setup and connections kit: declarative setup requirements, model readiness,
missing-secret states, OAuth grants, and provider connection health.
- Agent UX kit: sidebar, composer, staged context, mentions, voice, human
approval, generative UI, progress, and screen-state exposure.
- Custom block kit: optional extension creation, viewer chrome, slots, and
promotion affordances. Apps must opt in; Core keeps the sandbox, SQL storage,
access checks, and compatibility routes, while Toolkit owns reusable adoption
UI. Analytics may expose this as one-off Custom Blocks; durable behavior
should be promoted to app code.
- Chat history kit: presentational chat lists and recent-chat rails belong
in Toolkit; Core keeps thread persistence, agent execution, transport, and
page-to-sidebar handoff. Use Toolkit's
ChatHistoryRail for the standard
five-item sidebar preview and a footer row with New chat followed by an
ellipsis disclosure up to fifteen. Apps inject routing, labels, and domain
actions.
- Agent page kit: the full-page
/agent surface (AgentTabsPage from
@agent-native/core/client) with Context, Files, Connections, Jobs, and
Access tabs plus a Personal/Organization scope toggle. The canonical home
for context transparency, MCP servers, A2A remote agents, recurring
jobs/automations, and external-client connect flows. See the agent-page
skill.
- History and recovery kit: audit log, activity feed, version history,
checkpoints, undo, redo, restore, and proof-of-done.
- Comments and review kit: anchored comments, pins, mentions, review
requests, resolved threads, agent follow-up tasks, and notifications.
Implementation Checklist
When adding or refactoring one of these areas:
- Search existing framework and template code for duplicated UI or actions.
- Decide the shared contract: data shape, action API, feature-level headless
controller, default view, semantic components, and product-level render
slots.
- Keep shared data provider-agnostic and scoped by auth/sharing rules.
- Expose the same capability to the UI and agent through actions or documented
client helpers.
- Register app-specific labels, routes, resource adapters, and settings panels
instead of hardcoding app names in core UI.
- Update docs and relevant skills so future apps discover the shared path.
- Keep the component easy to adopt piecemeal: expose props/slots first and
ship readable source plus a complete ejection unit so apps can take ownership
of the smallest feature when needed. See
customizing-agent-native for the
configure → compose → eject → propose seam ladder.
- Keep one controller as the source of truth for the default and custom render
paths. A custom design must not fork actions, analytics, async state, or
accessibility behavior.
- Verify the default adapter and at least one non-Tailwind adapter with the
conformance kit, including focus and portal stacking across mixed overlay
implementations.
