+- **MCP**: MCPServer - Built-in MCP server executable for Kate editor tools
 - **UI**: ChatWidget, ChatWebView, ChatInputWidget, PermissionDialog
 - **Util**: KDEColorScheme - reads ~/.config/kdeglobals

-## Development Progress
-
-### Phase 1: Core Plugin Structure ✓
-- [x] CMake build system with KF6/Qt6 dependencies
-- [x] Directory structure
-- [x] KateCodePlugin with K_PLUGIN_CLASS_WITH_JSON registration
-- [x] KateCodeView with side panel tool view (left position)
-- [x] Basic ChatWidget placeholder
-- [x] Successful compilation
-
-### Phase 2: ACP Integration ✓
-- [x] ACPService with QProcess management
-- [x] ACPModels data structures
-- [x] ACPSession with protocol flow (initialize → session/new → session/prompt)
-- [x] ChatWidget integrated with ACP session
-- [x] Basic UI for testing (Connect button, chat display, message input)
-
-### Phase 3: Chat Functionality ✓
-- [x] ChatWebView with QWebEngineView and HTML/CSS/JS rendering
-- [x] ChatInputWidget with multiline input (Enter=send, Shift+Enter=newline)
-- [x] Message streaming display with role indicators and timestamps
-- [x] Tool call display in chat UI
-- [x] Qt resource system for bundling web assets
-- [x] JavaScript bridge for updating messages from C++
-
-### Phase 4: Full Features ✓
-- [x] KDE color scheme extraction from ~/.config/kdeglobals
-- [x] Color injection into WebView via JavaScript
-- [x] Permission dialog for tool approvals with option selection
-- [x] Error display via QMessageBox
-- [x] Permission response handling back to ACP
-
-### Phase 5: Kate Integration (TODO)
-- [ ] Context actions
-- [ ] File/selection context in prompts
-

+### ACP Provider Configuration
+- Providers are defined by `ACPProvider` struct: id, description, executable, options, builtin flag
+- Two built-in providers (Claude Code, Vibe/Mistral) are hardcoded and cannot be deleted
+- Custom providers are stored in QSettings via `beginWriteArray("ACP/customProviders")`
+- Active provider selection persisted as `ACP/activeProvider` string id
+- Provider selector is a QComboBox in the ChatWidget header (disabled while connected)
+- Unavailable executables shown grayed with "(not found)" suffix
+- Settings page shows a QTableWidget for managing custom providers (add/edit/remove)
+- Old `ACPBackend` enum settings are auto-migrated on first launch
+
 ### Web Interface
 - QWebEngineView loads HTML from Qt resources (qrc:/katecode/web/chat.html)
 - JavaScript functions exposed: `addMessage()`, `updateMessage()`, `finishMessage()`, `addToolCall()`, `updateToolCall()`
 - C++ calls JavaScript via `page()->runJavaScript()` with proper string escaping
 - CSS uses CSS variables for theming (ready for KDE color injection in Phase 4)
 - Responsive layout with message bubbles, tool call display, and streaming indicator
