## What
The settings discovery hero images (AI, Applications, Page Layouts,
Members, Data Model, APIs & Webhooks) baked the rounded border into the
pixels — transparent rounded corners plus a 1px edge stroke. Rendered
inside `Card rounded` — which already draws a 1px border + border-radius
and clips children with `overflow: hidden` — this produced a doubled,
slightly misaligned border.
This replaces all 12 files (light + dark per section) with clean
full-bleed exports (opaque square corners), so the border and rounding
come entirely from CSS.
## Notes
- Pure asset swap, no component changes.
- The MCP section's `.svg` cover is untouched (no new export provided).
Billing's unused cover is left as-is.
## Verification
- Each new image confirmed 1388×300, opaque square corners (no baked
border), correct light/dark variant.
- `Card` (twenty-ui) provides `border` + `border-radius` + `overflow:
hidden`, so the square images are clipped to the rounded card.
## Summary
Round through bosiraphael's 31 review threads on the merged PR #21072
(discovery hero + ephemeral playground token). The user asked to apply
each suggestion only where it adds value, so this PR is split into three
buckets.
### Comments (~17 threads)
- Tightened security-rationale / CSS-gotcha / API-doc comments to one or
two factual lines
- Kept (shortened) the comments above `RequireAccessTokenGuard` call
sites — without them a future reader could remove the guard and silently
reopen the escalation hole
- Kept (shortened) the in-memory-only rationale on
`playgroundApiKeyState` for the same reason
- Kept `flex: 1 + min-height: 0` CSS gotcha on `SubMenuTopBarContainer`
— non-obvious and easy to break
### Structure / extraction
- Move `WEBHOOK_TABLE_ROW_GRID_TEMPLATE_COLUMNS` to its own constants
file (one-export-per-file)
- Split `SettingsAgentToolsTab` and `SettingsAgentToolsTable` across
queries/, hooks/, types/, utils/:
- `graphql/queries/findManyApplicationsForToolTable.ts`
- `graphql/queries/findManyMarketplaceAppsForToolTable.ts`
- `hooks/useSettingsAgentToolsTable.ts` (data loading + index merging)
- `types/SettingsAgentToolItem|Application|MarketplaceApp`
- `utils/getToolApplicationId|getToolLink`
- Extract `SettingsAiModelsTab` optimistic mutations into
`hooks/useSettingsAiModelsActions` (handleModelFieldChange,
handleUseRecommendedToggle, handleModelToggle,
handleToggleAllVisibleModels)
- Extract `SettingsAI.handleCreateTool` into `hooks/useCreateTool`
- Drop unnecessary `useMemo` wrappers on `heroTabs` arrays
(SettingsObjects, SettingsLayout)
- Simplify `MenuItemToggle` handler in SettingsAgentSkillsTab:
`onToggleChange={setShowDeactivated}` (no longer wrapping with arrow +
read of stale `!showDeactivated`)
### Hero assets
- Replace placeholder `customize-illustration` with per-page exports
- Rename `layout/customize-illustration-{light,dark}.png` →
`layout/cover-{light,dark}.png`
- Add `cover-{light,dark}.png` for **applications** and **members**
(they were both pointing at the layout placeholder as a TODO)
- Overwrite `data-model/cover-*.png`, `playground/cover-*.png`,
`ai/ai-tools-cover-*.png` with the new exports
## Test plan
- [ ] `npx nx typecheck twenty-front` ✅
- [ ] `npx nx typecheck twenty-server` ✅
- [ ] `npx nx lint twenty-front` ✅ (oxlint + oxfmt, 0 warnings/errors)
- [ ] `/settings/layout`, `/settings/data-model`,
`/settings/applications`, `/settings/ai`, `/settings/api-webhooks`,
`/settings/members` each render the new hero illustration (light + dark)
- [ ] AI tab: tool list still loads, search + Custom/Managed/Standard
filters still work, "New Tool" still navigates to detail
- [ ] AI tab: Models tab — smart/fast model select, "Use best models
only" toggle, per-model checkboxes, toggle-all all still
optimistic+revert on error
- [ ] Skills tab: "Deactivated" toggle still flips show/hide
- [ ] Webhooks table still uses the 1fr 28px grid
## Summary
Two intertwined streams of work:
### UI — discovery hero pattern, settings shell, AI/API redesign
- **Generalize `SettingsDiscoveryHeroCard`** and use it on Layout, Data
Model, Apps, AI, API/Webhooks, Members. Drops 4 per-page wrapper files
(`SettingsObjectCoverImage`, `SettingsLayoutCoverImage`,
`SettingsLayoutCustomizeVideoModal`,
`SettingsDataModelVisualizeVideoModal`). Each page now supplies cover
src, modal id, and tab list.
- **Modal**: swap `<video>` placeholder for the Vimeo iframe pattern
from `twenty-docs`, per-tab `vimeoId`. Drop the parallel border-bottom
on the header (TabList draws its own baseline) and the grey background
behind the video. Note: Vimeo's embed allowlist applies — the iframes
load with the correct URL on `localhost` but the player itself requires
the video owner to allow the dev/staging domains in Vimeo settings.
- **AI page** rebuilt into a Cockpit pattern (Overview / Models / Skills
/ Tools / Usage). New `SettingsAiOverviewTab` with default Smart/Fast
pickers, at-a-glance stats, and an MCP signpost that deep-links to
`/settings/api-webhooks#mcp`. System Prompt link moved under Models.
Advanced tab removed.
- **API & Webhooks** now has 4 tabs (Playground / MCP / API Keys /
Webhooks). Hero card above tabs. Playground tab inverted to "Core API" /
"Metadata API" sections, each containing REST + GraphQL cards — schema
is the meaningful axis, protocol is secondary. Hash deep-link sync
delegated to the shared `TabListFromUrlOptionalEffect`.
- **Settings shell**: unified drawer outer padding (kill `isSettings`
branch), extract `CollapsibleNavigationDrawerSection`, add `iconColor`
on settings nav items, fix Exit Settings button alignment, 880px content
cap.
### Backend — strategy C: ephemeral playground token
The legacy paste-your-API-key flow is replaced by an on-demand
short-lived token scoped to the calling user's permissions. No shared
"Playground" API key to manage or revoke.
- New `JwtTokenTypeEnum.PLAYGROUND`. `PlaygroundTokenJwtPayload =
Omit<AccessTokenJwtPayload, 'type' | impersonation fields>` so any
future ACCESS claim flows through automatically.
- `AccessTokenService.generatePlaygroundToken` signs an access-shaped
JWT with `type: PLAYGROUND` and a configurable short TTL. A shared
private `resolveTokenSubject` helper parallelizes the user / workspace /
userWorkspace lookups for both generators.
- `JwtAuthStrategy.validateAccessToken` widened to accept
`AccessTokenJwtPayload | PlaygroundTokenJwtPayload`; impersonation gated
on `payload.type === ACCESS` so the union narrows without `as unknown
as` casts. The two branches in `validate()` collapse into one.
- New `PLAYGROUND_TOKEN_EXPIRES_IN` config var (default `2h`).
- New `generatePlaygroundToken` mutation (`WorkspaceAuthGuard`, no args,
returns `AuthToken`).
- Frontend `useOpenPlayground` hook centralizes mint → atom write →
navigate, with Apollo `onError` snackbar and a "use cached PLAYGROUND
token if still fresh" short-circuit (decodes via `jwt-decode`, checks
both `type` AND `exp`). Old API_KEY tokens left in localStorage from the
prior paste-form flow are rejected on `type` alone and force a re-mint —
this is what was causing the "This API Key is revoked" symptom on stale
browsers.
### Drive-by cleanups
- `PlaygroundToken` DTO removed (identical shape to `AuthToken` already
in use).
- 5 `customize-sidebar.webm` imports and the dead placeholder pipeline
removed.
## Test plan
### Discovery hero
- [ ] `/settings/layout`, `/settings/data-model`,
`/settings/applications`, `/settings/ai`, `/settings/api-webhooks`,
`/settings/members` each render the discovery hero card with its
illustration + play button + tabbed modal
- [ ] Modal tabs show the correct Vimeo embed URL per tab; aspect ratio
stays at 1440/900; no parallel border-bottom jog at the tab baseline
- [ ] AI Overview tab shows Smart/Fast model pickers + stats grid + MCP
signpost card; the MCP card lands on `/settings/api-webhooks#mcp` with
the MCP tab active
### API playground (ephemeral token)
- [ ] With an empty `playgroundApiKeyState` in localStorage, clicking
REST or GraphQL playground card opens the playground and the cached
token has `type: "PLAYGROUND"` with ~2h exp
- [ ] Clicking the card again within the freshness window does **not**
re-mint (`iat` / fingerprint stable across visits)
- [ ] Planting a fake API_KEY-shaped JWT in localStorage and clicking
the card forces a fresh mint (old token rejected on `type`)
- [ ] `GET /rest/companies?limit=1` with the cached token returns 200 +
real data
- [ ] `POST /graphql { __typename }` returns 200
### Settings shell
- [ ] Settings nav matches main app drawer padding; sections collapse;
Exit Settings button aligns with the workspace links above
- [ ] Active nav items have a right-gap (cleaner active state)
- [ ] Content area capped at 880px
### Verify
- [ ] `npx nx typecheck twenty-front` passes
- [ ] `npx nx typecheck twenty-server` passes
- [ ] `npx nx lint:diff-with-main twenty-front` passes
- [ ] `npx nx lint:diff-with-main twenty-server` passes
## Summary
- Refresh the settings application visuals with new light/dark PNG
covers for the data model card
- Replace the custom and standard application carousel assets with the
new provided illustrations
- Align app chips, type tags, and application detail previews with the
updated icon and description treatment
- Keep the data model cover container and overlay button behavior intact
while swapping the underlying imagery
## Testing
- Not run (not requested)
- Existing frontend typecheck and formatting checks were exercised
during implementation
