…ment and editing capabilities with project structure visibility
…de editing and preview capabilities; remove unnecessary components and integrate custom styles for improved UI
…ack functionality for real-time file operations; update project structure handling and improve initialization logic
- Updated chat API to accept files and file instructions in the request. - Introduced new client-side tools for file writing and command execution. - Added attemptCompletion tool to summarize task completion. - Improved system prompt to include current project files and organization guidelines. - Refactored right panel to expose Sandpack API for file operations. - Adjusted UI components for better spacing and layout. - Enhanced Sandpack editor and file explorer for improved usability. - Updated project template with a more structured React setup and Tailwind CSS integration. - Removed unused server-side tool definitions and related code.
…ve executeCommand functionality and integrate client-side tools
…untime) Add lib/engine/ (resolve + harness + local sandbox, ported from kobe) so the chat route auto-detects a locally logged-in claude/codex CLI and drives it via @ai-sdk/harness rooted at the project directory, falling back to OpenRouter. Upgrades ai to ^7 (@ai-sdk/react ^4, @ai-sdk/openai ^4 replacing the ai@6-only openrouter provider) and fixes pre-existing HEAD build breaks (missing streamdown dep, orphaned tool-definition type imports, removed setUrl).

What changed
codefox-local no longer hardcodes OpenRouter. A new
lib/engine/layer resolves which AI engine backs the app, per process:claudeCLI on PATH + logged in (oauthAccountin~/.claude.json). Default when present; uses the local subscription login, no API key.codexCLI on PATH +~/.codex/auth.jsoncredentials.OPENROUTER_API_KEY.Override with
CODEFOX_ENGINE=claude|codex|openrouter. No engine available → clear error.lib/engine/resolve.ts— detection + per-process cache.lib/engine/local-sandbox.ts— harness sandbox provider that runs on this machine, rooted at the project dir (ported from kobe).lib/engine/harness.ts— oneHarnessAgentruntime per (vendor, project dir), stateful session per project, returns the turn as a UIMessage stream Response (same wire format as the streamText path, so theuseChatclient is engine-agnostic). Runtimes are stashed onglobalThisto survive dev HMR;serverExternalPackageskeeps the harness bridge unbundled.app/api/chat/route.ts— resolves the engine per request. Harness path sends only the newest user message (the session is stateful) and passes no client tools — the runtime owns its own coding tools and edits the project files directly. OpenRouter path is unchanged..env.example— supported-engines list, resolution order, env vars.Smoke-tested live:
claudeengine streamed a two-turn stateful conversation throughPOST /api/chatundernext dev.ai@7 upgrade
The harness packages require
ai^7, so:ai^5 → ^7,@ai-sdk/react^2 → ^4, and@openrouter/ai-sdk-provider(peers ai ^6, incompatible) replaced by@ai-sdk/openai^4 withbaseURL: https://openrouter.ai/api/v1(chat/title routes). App-code breaks were mechanical:convertToModelMessagesis now async;isToolOrDynamicToolUIPart→isToolUIPart.Pre-existing build fixes
HEAD did not build (
next buildfails before this PR): missingstreamdowndependency, three tool renderers importing types removed fromlib/tool-definitions, andlib/client-tools.tscalling a removedRightPanelRef.setUrl. Fixed minimally (added the dep, inlined the types locally, dropped the deadsetPreviewUrlhelper) to get the build gate green.Notes
~/.codefox-local/projects/<id>directly; the Sandpack panel won't see those edits until it re-reads files (clientwriteFiletool only fires on the OpenRouter path). Follow-up if live-sync matters.app/api/chat/route.tshas uncommitted WIP in a local checkout that may conflict on merge.
