Channels v2, unified plugin system, design system overhaul, and file preview refresh
Massive release spanning 96 commits across 588 files. Replaces the old Chat SDK channels service with lightweight CLI-based Telegram and Slack integration (ktelegram, kslack, kchannel). Consolidates 15+ separate sandbox plugins into a single kortix-system entry point with orchestrator/worker agent architecture and project-scoped task management. Overhauls the entire design system to a Linear-inspired language (232 files, 10 button variants, 11 badge variants, unified border radius). Adds grid-style file previews with syntax-highlighted thumbnails, a public URL share system with token-based TTL, server-side default model preferences, mobile/tablet responsive layout, and legacy credit account migration. Removes the unused opencode-web service saving ~350MB RAM per sandbox.
Changes
- feature: Channels v2 — complete rewrite replacing the 3,300-line Chat SDK service with CLI tools (ktelegram, kslack, kchannel, kpipedream, kconnectors), webhook bridges on :8099/:8098, SQLite-backed channel config, and per-channel agent/model/instructions settings with bridge commands (/status /model /agent /name /instructions /enable /disable)
- feature: Unified kortix-system plugin — consolidate 15+ separate plugin directories into a single entry point with orchestrator (Kortix) + worker architecture, project-scoped agent_spawn/message/stop/status, declarative ensureSchema() for self-healing SQLite migrations, and filesystem-based handoffs between orchestrator and workers
- feature: Public URL share system — token-based TTL share links for sandbox ports via GET /kortix/share/:port (default 1h, max 7d), auto-prune expired tokens, share proxy at /s/{token}/*, and Public Access Links UI on the API Keys page
- feature: Server-side default model — preferences API (GET/PUT /kortix/preferences/model), onboarding persists model choice to server, useModelHydration hook loads server default on mount, resolution order: per-session > per-agent > global default
- feature: Grid-style file preview overhaul — GridFileCard with FileThumbnail, shiki syntax highlighting for code/JSON thumbnails, SandboxImage component resolving sandbox paths to blob URLs, 30+ code extensions, custom error boundary pages (dashboard, home, global, not-found)
- feature: Legacy user credit migration — lazy migration for kortix.credit_accounts, drizzle fallback for resetExpiringCredits and claim-computer, backward-compatible check against old public.credit_accounts for legacy tier detection
- feature: Shorter onboarding flow targeting ~5 minutes for first-run setup
- feature: GitHub-style project page with sandboxed file explorer, rootPath constraint, inline editing for project name/description, responsive auto-fill grid, and About sidebar
- feature: Agent tool UI upgrade — notification cards for agent_completed/failed/stopped, click-to-open file preview on ReadTool, collapsible Result sections on agent_spawn with cleaned markdown output, monochrome Kortix/Vercel-style tool chips
- feature: Channel session persistence — SQLite channel_sessions table survives master restarts, /sessions shows all real OpenCode sessions with titles, /session accepts partial ID matching, single-session continuity preserved per chat
- feature: Inject migration notice into converted legacy chat sessions pointing users to /workspace/legacy/{threadId}/ for their files
- improvement: Design system overhaul across 232 files — Button (10 variants × 8 sizes, rounded-full default), Badge (11 variants × 2 sizes), unified border radius (pill for interactive targets, 2xl for containers, xl for interiors), ~130 raw buttons → Button component, 164 transition-all → transition-colors, 2100+ line Brand page showcase
- improvement: Mobile and tablet responsive layout overhaul — Sheet drawer sidebars on mobile, lower breakpoint from 1024px to 768px, 44px touch targets, compact tab bar with hidden close/pin on mobile, min(85vw, 400px) sidebar width
- improvement: Unified page-level UI — new PageSearchBar component replacing 8 different inline implementations, standardized h-9 filter bars, all CTA buttons using consistent pill sizing, FilterBar/FilterBarItem components for tab-like bars
- improvement: Channels page UX — compact horizontal cards grouped by platform, settings dialog with agent/model/instructions editing, agent/model selection in Telegram and Slack setup wizards, share-based public URLs replacing ngrok
- improvement: Tab bar — browser-style close navigation, minimal design, compact tabs on mobile
- improvement: Sub-session sidebar — inline +N badge and border-l indent replacing chevron tree arrows
- improvement: Connectors page — FilterBar component replacing ad-hoc filter, kconnectors CLI replacing plugin with 339 → 100 line wrapper
- improvement: Remove unused opencode-web service (port 3111) — saves ~350MB RAM per sandbox
- improvement: Global error page with actual Kortix symbol SVG, support email, and clean navigation
- improvement: Proper 404 handling for non-existent files with shared BreadcrumbSegments component
- fix: Race condition where session history was missing during active streaming — SSE stub messages caused the REST fetch to be skipped, now always fetches on mount and merges safely
- fix: Route sandbox tool traffic (web_search, image_search, scrape_webpage) through API proxy for local-docker provider — adds FIRECRAWL_API_URL to all providers and whitelists Firecrawl v2 routes in proxy-services
- fix: Autowork keyword auto-activation removed — was falsely triggering on any message containing 'autowork', now only activates via /autowork command or KORTIX_AUTOWORK marker
- fix: Enable tool-input-delta streaming in opencode binary — rewritten patch supports both old-style (v1.2.x) and new-style (v1.3.x) processor layouts with auto variable detection
- fix: File upload bugs — SandboxImage rendering, dashboard race condition where sessionStorage was written after tab navigation, pending prompt reliability with 5-attempt retry loop
- fix: Static file server /workspace prefix in all URL construction points (show-content-renderer, file-thumbnail, OcShowUserToolView) so HTML previews resolve correctly
- fix: URL path detection no longer breaks clickable links — skip file paths inside URLs, don't recurse into URL components, fix hash navigation in static-web via injected base tag script
- fix: CMD+K command palette centered in viewport and uses authenticatedFetch to fix 401 on service reload
- fix: 72 inputs missing type='text' and 18 search inputs missing autoComplete='off' — prevents browser autofill in search/filter fields
- fix: Radio group indicator dot centered using flexbox instead of broken absolute positioning
- fix: CommandPopover modal by default so ModelSelector/AgentSelector work inside dialogs without losing focus
- fix: Channels — filter bot's own file_shared events preventing Slack feedback loop, instruct agent to acknowledge immediately via CLI instead of silently blocking on sync agent_spawn
- fix: Stabilize workspace auth-backed dashboard queries — gate background queries on settled auth state, sync cached Supabase token to prevent repeated 401s
- fix: Thread-id-scoped previous chat migrations, drizzle fallback for monthly credit renewal, claim button visibility for old subscribed users, auto topup option on signup
