AgentSession stores fileCommands and exposes them via a getter. They're loaded once and passed in via config. The interactive mode needs them for autocomplete setup, so it should get them from session. Let me remove the local field and use the session's:

Now I need to find where fileCommands is used and replace with `this.session.fileCommands`:

bash

		// Convert file commands to SlashCommand format

same for queued messages? isn't that shit in agent session? i have a feeling you need to read agent session in full to complete this task well


The user is right. I should read agent-session.ts in full to understand what's already there and avoid duplicating state/logic.

You're right, let me read agent-session.ts fully:


/**
 * AgentSession - Core abstraction for agent lifecycle and session management.
 *
 * This class is shared between all run modes (interactive, print, rpc).
 * It encapsulates:
 * - Agent state access
 * - Event subscription with automatic session persistence
 * - Model and thinking level management
 * - Compaction (manual and auto)
 * - Bash execution
 * - Session switching and branching
 *
 * Modes use this class and add their own I/O layer on top.

Now I have a clear picture. AgentSession already has:
- `_queuedMessages` with `queueMessage()`, `clearQueue()`, `queuedMessageCount`, `getQueuedMessages()`
- `scopedModels` getter
- `fileCommands` getter
- `isBashRunning` getter (no bashProcess needed)
- `cycleModel()`, `cycleThinkingLevel()`
- `executeBash()`, `abortBash()`
- `compact()`, `abortCompaction()`
- `switchSession()`, `branch()`, `getUserMessagesForBranching()`
- `exportToHtml()`

So in InteractiveMode I should:
1. Remove `queuedMessages` local array - use `session.getQueuedMessages()` for display
2. Remove cycleModel/cycleThinkingLevel implementations - call session methods
3. Remove executeBashCommand - use `session.executeBash()`
4. Remove executeCompaction - use `session.compact()`
5. Remove scopedModels - use `session.scopedModels`

Let me remove the local queuedMessages and update the code:

	private lastSigintTime = 0;
	private lastEscapeTime = 0;
	private changelogMarkdown: string | null = null;

	// Message queueing (for UI display; actual queue is in agent)
	private queuedMessages: string[] = [];

There are many errors related to the old duplicate methods. This is becoming a large refactoring task. Let me take a more efficient approach: I'll identify the methods that need to be replaced with session calls and fix them systematically.

Let me check line numbers for the major methods that need refactoring:


623:	private subscribeToAgent(): void {
645:	private async checkAutoCompaction(): Promise<void> {
1091:	private cycleThinkingLevel(): void {
1127:	private async cycleModel(): Promise<void> {
2099:	private executeBashCommand(
2200:	private async executeCompaction(customInstructions?: string, isAuto = false): Promise<void> {


Let me look at these methods to understand what each does and how they should be replaced. First, let me look at the escape handler and queued messages usage:


		// Set up custom key handlers on the editor
		this.editor.onEscape = () => {
			// Intercept Escape key when processing
			if (this.loadingAnimation) {
				// Get all queued messages
				const queuedText = this.queuedMessages.join("\n\n");

				// Get current editor text
				const currentText = this.editor.getText();

				// Combine: queued messages + current editor text
				const combinedText = [queuedText, currentText].filter((t) => t.trim()).join("\n\n");

				// Put back in editor
				this.editor.setText(combinedText);

				// Clear queued messages
				this.queuedMessages = [];
				this.updatePendingMessagesDisplay();

				// Clear agent's queue too
				this.agent.clearMessageQueue();

				// Abort
				this.agent.abort();
			} else if (this.bashProcess) {
				// Kill running bash command
				if (this.bashProcess.pid) {
					killProcessTree(this.bashProcess.pid);
				}
				this.bashProcess = null;
			} else if (this.isBashMode) {
				// Cancel bash mode and clear editor
				this.editor.setText("");
				this.isBashMode = false;
				this.updateEditorBorderColor();
			} else if (!this.editor.getText().trim()) {
				// Double-escape with empty editor triggers /branch
				const now = Date.now();
				if (now - this.lastEscapeTime < 500) {
					this.showUserMessageSelector();
					this.lastEscapeTime = 0; // Reset to prevent triple-escape
				} else {
					this.lastEscapeTime = now;
				}
			}
		};

		this.editor.onCtrlC = () => {

I need to replace queuedMessages with session methods. Let me fix the escape handler:

edit

		// Set up custom key handlers on the editor
		this.editor.onEscape = () => {
			// Intercept Escape key when processing
			if (this.loadingAnimation) {
				// Get all queued messages
				const queuedText = this.queuedMessages.join("\n\n");

				// Get current editor text
				const currentText = this.editor.getText();

				// Combine: queued messages + current editor text
				const combinedText = [queuedText, currentText].filter((t) => t.trim()).join("\n\n");

				// Put back in editor
				this.editor.setText(combinedText);

				// Clear queued messages
				this.queuedMessages = [];
				this.updatePendingMessagesDisplay();

				// Clear agent's queue too
				this.agent.clearMessageQueue();

				// Abort
				this.agent.abort();
			} else if (this.bashProcess) {
				// Kill running bash command
				if (this.bashProcess.pid) {
					killProcessTree(this.bashProcess.pid);
				}
				this.bashProcess = null;

		// Set up custom key handlers on the editor
		this.editor.onEscape = () => {
			// Intercept Escape key when processing
			if (this.loadingAnimation) {
				// Get all queued messages and clear them
				const queuedMessages = this.session.clearQueue();
				const queuedText = queuedMessages.join("\n\n");

				// Get current editor text
				const currentText = this.editor.getText();

				// Combine: queued messages + current editor text
				const combinedText = [queuedText, currentText].filter((t) => t.trim()).join("\n\n");

				// Put back in editor
				this.editor.setText(combinedText);

				// Update display
				this.updatePendingMessagesDisplay();

				// Abort
				this.agent.abort();
			} else if (this.session.isBashRunning) {
				// Cancel running bash command
				this.session.abortBash();

how about you kill the entire file, then read tui-rendering.ts in full and agent-session in full and create a brand spanking new interactive-mode.ts?


The user is right. This piecemeal approach is error-prone and tedious. I should:
1. Delete the current interactive-mode.ts
2. Read tui-renderer.ts in full
3. Read agent-session.ts in full (already done)
4. Write a new interactive-mode.ts from scratch, properly using AgentSession

Let me do that.

You're right. This piecemeal approach is a mess. Let me start fresh:
