Changelog

​

Auto-compile

• Auto-compile — background compile gated on actual input changes (write_file / edit_file tool hooks plus watchers on subspaces, automation-tests, application.json, compile.ts, app.ts, root.ts); errors surface in a banner with an Ask button that hands the failure to the agent.

​

Sync

• Sync pills next to the Actions menu show whether the server has new commits or the local clone is ahead. Check for Updates in Actions manually triggers a sync check with a brief outcome flash.
• Update Config dialog — pre-flight refuses to push when the server is ahead, awaits inline auto-compile, and propagates compile errors instead of silently pushing a stale build.
• Non-force Pull — separate Pull / Force Pull buttons. Non-force pull branches at the server’s last commit, lands a 3-way merge on main, and surfaces conflicts as auto-compile errors instead of failing the pull.

​

Skills

• Skills installer — install third-party skills from a public GitHub repo (e.g. vercel-labs/skills) or local folder, with recursive skill detection, multi-select, conflict warnings, and Global / Project scope.

​

Sessions

• Session archive — right-click Archive replaces immediate Delete in the sidebar. New Settings → Archive tab groups archived sessions by project with per-row Recover and two-step Delete forever.
• Rename projects from the sidebar’s more-menu (writes the new name to application.json; Enter commits, Escape cancels).

​

Chat

• Ask Question — the agent can pause and ask 1–4 multiple-choice clarifying questions inline in chat, with a Custom free-text fallback per question.
• /compact slash command — manually compact the conversation without waiting for the context limit (the popup hides the entry when the compactor wouldn’t find a useful cut). Supports an optional follow-up prompt.
• Custom Instruction now has an explicit Save button (no more blur-triggered autosave). The persisted block is scoped: user wording is treated as a personal rule but prior system-prompt rules win on conflict.
• Main agent recognizes share-app URLs (control.bricks.tools/#/create-share-app, share.bricks.tools/app/) and hands off to the BRICKS CLI share-app workflow.

​

Other

• Other performance and stability improvements.

​

Preview

• Draw mode — annotate the embedded preview with a pen overlay and attach the composite (preview screenshot + strokes) to the chat input.

​

Chat

• Workspace profile selector in the chat input — project chats display the project’s workspace; main chat lets you switch the active auth profile (with a confirmation step since it rebuilds the agent’s system prompt).
• Long sessions paginate with inline “Show N hidden replies” buttons (fully-rendered window capped to 50 messages).
• Tool-call file content (write_file / edit_file / read_file) renders as syntax-highlighted code or a unified diff with expand-to-full-size; streaming bodies update token-by-token.
• Brand animation plays alongside the elapsed timer while the agent is running.
• Streaming render is rAF-coalesced and historical bubbles short-circuit; new markdown blocks fade and slide in as they arrive.
• Render an image attachment only when the active model supports vision; cap chat image preview (80px) and rendered image (400px) heights.
• Chat input auto-resizes when prompts are set programmatically (Inspect, popped-out preview, history nav, etc.).

​

Agent

• System notification and sound when an agent run finishes or needs approval and the app is off-focus (toggle in Settings → Agent).
• New set_session_title tool summarizes the current task into a sidebar-fit title.
• Agent loads matching skills when you type /<skill-name> in chat.
• Allow read_file with absolute paths inside the project directory.
• Auto-recover from context_length_exceeded errors via on-demand compaction and automatic retry; the context indicator drops immediately after compaction.

​

Local Devices

• Scan and integrate discovered buttress-servers via “Ask Agent to integrate” (multi-select supported; selection is mutually exclusive with devtools rows).

​

Settings

• Accent color in Settings → Appearance.

​

Sidebar and window

• Window background blur supported on the light theme.
• Top bar collapses Diff / Open in editor / Actions / Open Controller to icons on narrow widths so it stays single-line.
• Larger sidebar section title bars; drop the default chat-bubble icon from regular sessions.
• Remember the Controller window position and size.

​

Models

• Preserve reasoning_content for kimi-k2.5 / kimi-k2.6 via opencode / opencode-go.

​

Other

• Self-update BRICKS CLI in the background for binary installs (npm/bun-managed installs are not modified).
• React error boundary catches render crashes, reports to Bugsnag, and shows a reload-able fallback.
• Other stability improvements.

​

Fixes

• Eliminate “Agent is already processing” races during multi-turn runs and queued-input auto-send.

​

Chat

• Main Chat — project-agnostic agent for general BRICKS workflows. The empty state surfaces a provider setup guide, a Local Devices panel, and an Open BRICKS Controller shortcut. Sidebar splits into Projects and Chat sections.
• Pinned Sessions — starred sessions appear in a dedicated sidebar section.
• Render mermaid diagrams in chat with the BRICKS theme.

​

Providers

• API key test validation in Settings → Providers for Anthropic, OpenAI / baseUrl, Google AI Studio, Google Vertex, OpenAI Codex, and custom providers.

​

Models

• New opencode provider models: kimi-k2.6 and deepseek-v4-flash / deepseek-v4-pro. The opencode-go default is bumped to kimi-k2.6. See models.

​

Sandbox

• Detect dangerous bash commands and force a permission prompt. See sandbox.

​

Sidebar and window

• Narrower minimum sidebar width with compact polish; bottom actions moved to the Projects header.
• macOS: reclaim titlebar space in fullscreen.
• Widen the controller drag strip without blocking clicks underneath.

​

Preview

• Send theme changes to the preview pane.
• Always show the DevTools button on local devices; non-probed devices prompt for a passcode. Local Devices renders as an inline chat panel.
• Disable the inner preview title bar.
• DevTools / CDP screencast is disabled by default.

​

Settings

• Reuse the chip-style Model / Thinking selectors from the chat input.
• Jump from the ACP indicator to its setting.

​

Other

• “Open Folder in CTOR” Finder Service for macOS.
• Add a Changelog link to the Help menu.
• Limit Open Project scan to immediate subdirectories.
• Cut git index.lock contention from the watcher fan-out during deploy / pull / update.
• Other stability improvements.

​

Fixes

• Clear stale chat when removing a project.
• Constrain the login OTP input to the server’s 5-letters + 4-digits format.
• Don’t navigate input history during IME composition.
• Stop persisting default allowed sandbox domains so future default updates reach existing users.
• Dedupe API error notifications and clear stale messages on session switch.
• Keep Auth0 redirects inside the controller window so login completes in-app.

​

Models

• New defaults: openai/gpt-5.5 for OpenAI and openai-codex/gpt-5.5 for Codex. See models.
• gpt-5.3-codex-spark is now gated to the ChatGPT Pro plan.

​

Providers

• Edited message resend uses the correct model fallback.
• Include all generated and post-install paths when staging an update.
• Resolve missing migration after the CTOR rename.

​

Highlights

• AI-agent conversational workflow — build BRICKS applications by chatting with the built-in AI agent. Review file edits and tool calls in the integrated diff view.
• Integrated Controller view — preview and manage your workspace directly from the desktop app, without switching to the web.
• Web Preview CDP bridge — external CDP clients (Chrome DevTools, Playwright, bricks devtools) can connect to the CTOR preview via a local WebSocket server. Currently available in CTOR only.
