* feat: Add token budget tracking and multiple improvements
## Features
- **Token Budget Visualization**: Added real-time token usage tracking with pie chart display showing percentage used (blue < 50%, orange < 75%, red ≥ 75%)
- **Show Thinking Toggle**: Added quick settings option to show/hide reasoning sections in messages
- **Cache Clearing Utility**: Added `/clear-cache.html` page for clearing service workers, caches, and storage
## Improvements
- **Package Upgrades**: Migrated from deprecated `xterm` to `@xterm/*` scoped packages
- **Testing Setup**: Added Playwright for end-to-end testing
- **Build Optimization**: Implemented code splitting for React, CodeMirror, and XTerm vendors to improve initial load time
- **Deployment Scripts**: Added `scripts/start.sh` and `scripts/stop.sh` for cleaner server management with automatic port conflict resolution
- **Vite Update**: Upgraded Vite from 7.0.5 to 7.1.8
## Bug Fixes
- Fixed static file serving to properly handle routes vs assets
- Fixed session state reset to preserve token budget on initial load
- Updated default Vite dev server port to 5173 (Vite's standard)
## Technical Details
- Token budget is parsed from Claude CLI `modelUsage` field in result messages
- Budget updates are sent via WebSocket as `token-budget` events
- Calculation includes input, output, cache read, and cache creation tokens
- Token budget state persists during active sessions but resets on session switch
* feat: Add session processing state persistence
Fixes issue where "Thinking..." banner and stop button disappear when
switching between sessions. Users can now navigate freely while Claude
is processing without losing the ability to monitor or stop the session.
Features:
- Processing state tracked in processingSessions Set (App.jsx)
- Backend session status queries via check-session-status WebSocket message
- UI state (banner + stop button) restored when returning to processing sessions
- Works after page reload by querying backend's authoritative process maps
- Proper cleanup when sessions complete in background
Backend Changes:
- Added sessionId to claude-complete, cursor-result, session-aborted messages
- Exported isClaudeSessionActive, isCursorSessionActive helper functions
- Exported getActiveClaudeSessions, getActiveCursorSessions for status queries
- Added check-session-status and get-active-sessions WebSocket handlers
Frontend Changes:
- processingSessions state tracking in App.jsx
- onSessionProcessing/onSessionNotProcessing callbacks
- Session status check on session load and switch
- Completion handlers only update UI if message is for current session
- Always clean up processing state regardless of which session is active
* feat: Make context window size configurable via environment variables
Removes hardcoded 160k token limit and makes it configurable through
environment variables. This allows easier adjustment for different
Claude models or use cases.
Changes:
- Added CONTEXT_WINDOW env var for backend (default: 160000)
- Added VITE_CONTEXT_WINDOW env var for frontend (default: 160000)
- Updated .env.example with documentation
- Replaced hardcoded values in token usage calculations
- Replaced hardcoded values in pie chart display
Why 160k? Claude Code reserves ~40k tokens for auto-compact feature,
leaving 160k available for actual usage from the 200k context window.
* fix: Decode HTML entities in chat message display
HTML entities like < and > were showing as-is instead of being
decoded to < and > characters. Added decodeHtmlEntities helper function
to properly display angle brackets and other special characters.
Applied to:
- Regular message content
- Streaming content deltas
- Session history loading
- Both string and array content types
* refactor: Align package.json with main branch standards
- Revert to main branch's package.json scripts structure
- Remove custom scripts/start.sh and scripts/stop.sh
- Update xterm dependencies to scoped @xterm packages (required for code compatibility)
- Replace xterm with @xterm/xterm
- Replace xterm-addon-fit with @xterm/addon-fit

* feat: Replace CLI implementation with Claude Agents SDK
This commit completes the migration to the Claude Agents SDK, removing the legacy CLI-based implementation and making the SDK the exclusive integration method.
Changes:
- Remove claude-cli.js legacy implementation
- Add claude-sdk.js with full SDK integration
- Remove CLAUDE_USE_SDK feature flag (SDK is now always used)
- Update server/index.js to use SDK functions directly
- Add .serena/ to .gitignore for AI assistant cache
Benefits:
- Better performance (no child process overhead)
- Native session management with interrupt support
- Cleaner codebase without CLI/SDK branching
- Full feature parity with previous CLI implementation
- Maintains compatibility with Cursor integration

* fix: Prevent stale token-usage data from updating state on session switch
- Add AbortController to cancel in-flight token-usage requests when session/project changes
- Capture session/project IDs before fetch and verify they match before updating state
- Handle AbortError gracefully without logging as error
- Prevents race condition where old session data overwrites current session's token budget
