  • Implement unified storage architecture 
    - Replace fragmented storage backends with single IndexedDBStorageBackend
- Create multi-store StorageBackend interface (storeName parameter)
- Remove old backends: IndexedDBBackend, LocalStorageBackend, SessionIndexedDBBackend, WebExtensionStorageBackend
- Remove old repositories: ProviderKeysRepository, SessionRepository, SettingsRepository
- Simplify AppStorage to directly expose storage methods (getSetting/setSetting, getProviderKey/setProviderKey)
- Create SessionsRepository for session-specific operations
- Update all consumers to use new simplified API
- Update example app to use new storage architecture
- Benefits: 10GB+ quota (vs 10MB chrome.storage), single database, consistent API

  • Fix spinner showing on aborted tool calls in javascript-repl and artifacts renderers 
    When isStreaming is false and there's no result (aborted state), show 'complete' state instead of 'inprogress' to avoid showing the spinner.

  • Simplify navigation tracking - insert message on every active tab URL change 
    - Remove complex agent busy state tracking
- Remove checkAndInsertNavMessage helper and onBeforeSend logic
- Directly insert navigation messages when tab URL changes (chrome.tabs.onUpdated)
- Also insert when user switches to a different tab (chrome.tabs.onActivated)

  • Insert navigation messages when agent finishes working (after tool execution) 
    - Track agent busy state: isStreaming OR pendingToolCalls.size > 0
- When agent transitions from busy to idle, check for URL changes
- Extract checkAndInsertNavMessage() helper function
- Call helper from both onBeforeSend (user submit) and agent state subscription (post-tool)
- Fixes issue where browser_javascript tool navigates page but no nav message inserted
- Navigation messages now appear after tools that change window.location.href

  • Only insert navigation messages on user message submit, not during idle browsing 
    - Remove automatic navigation message insertion from tab change listeners
- Tab listeners now only track current tab state (currentTabUrl, currentTabIndex)
- Navigation messages are only inserted via onBeforeSend callback when user submits
- Prevents spam of navigation messages when user is just browsing without interacting with agent

  • Improve navigation message visibility and favicon handling 
    - Add fallback favicon using Google's favicon service (s2/favicons API)
- If both tab.favIconUrl and Google service fail, gracefully hide broken image
- Enhance navigation message styling for better visibility:
  - Use accent colors (bg-accent/50 with border-accent) instead of muted secondary
  - Increase padding (px-3 py-2) and add vertical margin (my-2)
  - Add shadow-sm for subtle depth
  - Make title font-medium for better contrast
  - Use border-2 instead of border for more prominence

    Major architectural improvements:
- Renamed AgentSession → Agent (state/ → agent/)
- Removed id field from AgentState
- Fixed transport abstraction to pass messages directly instead of using callbacks
- Eliminated circular dependencies in transport creation

Transport changes:

Session storage:
- Added SessionRepository with IndexedDB backend
- Auto-save sessions after first exchange
- Auto-generate titles from first user message
- Session list dialog with search and delete
- Persistent storage permission dialog
- Browser extension now auto-loads last session

UI improvements:

- Added drag & drop file upload to MessageEditor
- Fixed artifacts panel auto-opening on session load
- Added "Drop files here" i18n strings
- Changed "Continue Without Saving" → "Continue Anyway"

Web example:
- Complete rewrite of main.ts with clean architecture
- Added check script to package.json

- History and new session buttons
- Auto-load most recent session on open

  • Add Anthropic prompt caching, pluggable storage, and CORS proxy support 
    Storage Architecture:
- New pluggable storage system with backends (LocalStorage, ChromeStorage, IndexedDB)
- SettingsRepository for app settings (proxy config, etc.)
- ProviderKeysRepository for API key management
- AppStorage with global accessors (getAppStorage, setAppStorage, initAppStorage)

Transport Refactoring:
- Renamed DirectTransport → ProviderTransport (calls LLM providers with optional CORS proxy)
- Renamed ProxyTransport → AppTransport (uses app server with user auth)
- Updated TransportMode: "direct" → "provider", "proxy" → "app"

CORS Proxy Integration:
- ProviderTransport checks proxy.enabled/proxy.url from storage
- When enabled, modifies model baseUrl to route through proxy: {proxyUrl}/?url={originalBaseUrl}
- ProviderKeyInput test function also honors proxy settings
- Settings dialog with Proxy tab (Switch toggle, URL input, explanatory description)

Anthropic Prompt Caching:
- System prompt cached with cache_control markers (both OAuth and regular API keys)
- Last user message cached to cache conversation history
- Saves 90% on input tokens for cached content (10x cost reduction)

Settings Dialog Improvements:
- Configurable tab system with SettingsTab base class
- ApiKeysTab and ProxyTab as custom elements
- Switch toggle for proxy enable (instead of Checkbox)
- Explanatory paragraphs for each tab
- ApiKeyPromptDialog reuses ProviderKeyInput component

Removed:
- Deprecated ApiKeysDialog (replaced by ProviderKeyInput in SettingsDialog)
- Old storage-adapter and key-store (replaced by new storage architecture)

- Add JailJS content script with ES6+ transform support
- Expose DOM constructors (Event, KeyboardEvent, etc.) to JailJS
- Support top-level await by wrapping code in async IIFE
- Add returnFile() support in JailJS execution
- Refactor KeyStore into pluggable storage-adapter pattern
- Make ChatPanel configurable with sandboxUrlProvider and additionalTools
- Update jailjs to 0.1.1

Files deleted (33 duplicate files):

  • Add JavaScript REPL tool to web-ui package 
    - Created javascript-repl.ts tool with SandboxedIframe for code execution
- Integrated into ChatPanel replacing calculate and getCurrentTime tools
- REPL provides full browser API access with external library support
- Auto-registers renderer for tool output display
- Uses srcdoc instead of sandbox.html (no CSP restrictions in web apps)

    8212623af0
  • Fix race condition in web-ui SandboxedIframe 
    Fixed loadContent() and execute() to set srcdoc at the correct time:
- loadContent(): Now sets srcdoc after creating iframe (was missing entirely)
- execute(): Now sets srcdoc after setting up message listeners and creating iframe (was setting before iframe existed)

This prevents missing postMessage events from the sandboxed iframe.
