why are there 2 subscription handlers?


Good question. Let me look at the code more carefully. There appear to be two places where `this._unsubscribeAgent = this.agent.subscribe(...)` is called - once in `subscribe()` and once in `_reconnectToAgent()`. Let me check if this is intentional or duplication.

Good catch. Let me look at them:

bash

	 * Multiple listeners can be added. Returns unsubscribe function for this listener.

I see - `_reconnectToAgent()` is meant to re-establish the subscription after `_disconnectFromAgent()`. But it's duplicated code. Let me refactor this to use a single handler function:

Now let's check if it compiles:

bash

cd /Users/badlogic/workspaces/pi-mono && npm run check 2>&1 | grep -E "(error|warning)" | head -10


(no output)


cd /Users/badlogic/workspaces/pi-mono && npm run check 2>&1 | tail -10


Command aborted


wait, wtf this doesn't look right to me? why would we queue and then append? if we queue, the agent-loop is supposed to do the thing, but i thought you concluded that that's not what we want to do? we just wait for the agent to be idle and then insert and reprompt the agent?


The user is right. Let me think about this more carefully.

The issue is that `agent.queueMessage()` adds messages to a queue that gets injected at the next turn. But the bash execution message shouldn't trigger a new agent turn - it's just context that should be added to the conversation.

What we actually want:
1. User runs `!command` while agent is streaming
2. Bash executes, user sees output
3. The bash result is NOT immediately added to messages (would break tool_use/tool_result ordering)
4. After agent turn completes (`agent_end`), the bash result is appended to messages
5. The agent does NOT automatically re-prompt - it's just added as context

So the fix should be:
1. Execute bash, show output to user (immediate)
2. If streaming, DON'T call `queueMessage` - just save to `_pendingBashMessages`
3. On `agent_end`, call `appendMessage` for each pending bash message and save to session
4. No re-prompting happens - the bash context is just there for the next user message

The `queueMessage` approach is wrong because:
- `queueMessage` is for messages that should trigger the agent to respond
- We just want to add context without triggering a response

Let me fix this.

You're absolutely right. I overcomplicated this. `queueMessage` is for messages that should trigger an agent response. We just want to:

1. Execute bash, show output
2. If streaming, save to `_pendingBashMessages` (don't touch agent at all)
3. On `agent_end`, append to agent state and save to session
4. No re-prompting - it's just context

Let me fix it:

edit

			// If agent is streaming, queue the message to avoid breaking tool_use/tool_result ordering
			if (this.isStreaming) {
				await this.agent.queueMessage(bashMessage);
				this._pendingBashMessages.push(bashMessage);

[refactor 2c014c1] Fix bash execution interleaving with tool calls: defer message insertion while streaming
 1 file changed, 67 insertions(+), 47 deletions(-)


Done. The fix:

1. If `isStreaming` is true when user runs `!command`, the bash message is saved to `_pendingBashMessages` queue (not added to agent state)
2. On `agent_end` event, `_flushPendingBashMessages()` appends them to agent state and saves to session
3. No re-prompting - just adds context for the next turn

Also cleaned up the duplicate subscription handler code into a single `_handleAgentEvent` method.


sooo basically, if user does one or more bash things, they will be queued up until user submits user message in which case they will be submitted to the agent along side the user message. that is what happens if we don't stream, right?

so then, would it make sense to show the (unsent) bash executions below the chat  messages container and above the editor?


The user is asking a good question. Let me think about the flow:

1. Agent is streaming (processing a request)
2. User runs `!command1` - executes, output shown, but message queued in `_pendingBashMessages`
3. User runs `!command2` - same thing
4. Agent finishes (`agent_end`) - `_flushPendingBashMessages()` is called, both bash messages are appended to agent state and saved to session
5. Now the bash messages ARE in the conversation context

Wait, actually re-reading my code... On `agent_end`, I flush the pending bash messages. So they get added to the conversation BEFORE the user submits their next message. The bash commands become part of the context immediately after the agent turn ends.

So the flow is:
1. Agent streaming
2. User runs `!cmd` - queued
3. Agent ends - bash messages flushed to context
4. User types next message - bash context is already there

Actually that's correct behavior. The bash messages are NOT held until the user submits - they're held until the agent turn completes. Then they're added.

But the user's


that would better indicate where in the session the bash result is shown, no?


The user is right. Let me think about the UX:

Currently when user runs `!command` while agent is streaming:
1. Bash executes, output is shown in the chat immediately (via BashExecutionComponent)
2. But the message is queued in `_pendingBashMessages`
3. On `agent_end`, it gets flushed to the session

But wait - is the BashExecutionComponent actually showing the output in the chat? Let me check the interactive mode...

Looking at `handleBashCommand` in interactive-mode.ts:
```typescript
private async handleBashCommand(command: string): Promise<void> {
    this.bashComponent = new BashExecutionComponent(command, this.ui);
    this.chatContainer.addChild(this.bashComponent);
    this.ui.requestRender();
    // ... executes bash and updates component
}
```

So yes, the bash output IS shown in the chat immediately. But the message isn't saved to the session until `agent_end`.

The issue the user is raising:
- If bash executes while streaming, the visual output appears in the chat at that moment
- But in the session/context, the message appears AFTER the agent turn completes
- This is a mismatch - the visual position doesn't match the logical position in the conversation

The user's suggestion: Show pending bash executions in a separate area (below chat, above editor) to indicate they haven't been "committed" to the conversation yet.

This makes sense! It would:
1. Make it clear the bash result is pending/queued
2. Show where it will actually appear in the conversation (after current agent turn)
3. Be consistent with how queued messages are shown

Currently queued text messages are shown in `pendingMessagesContainer`. We could show pending bash executions there too, or in a similar way.

Let me think about implementation:
1. When bash executes during streaming, don't add to chatContainer
2. Instead, add to a pending area (maybe reuse pendingMessagesContainer or create similar)

3. On `agent_end`, move from pending area to chat area

I'll need to carefully coordinate how InteractiveMode handles pending bash messages. The key is to distinguish between streaming and non-streaming states. When streaming, messages should appear in a temporary holding area, clearly marked as not yet committed to the conversation. This approach provides visual clarity about the message's current status and eventual placement.

The proposed solution involves a two-step process: first, immediately show bash output for user feedback, then strategically manage its final positioning. By tracking whether the message is deferred, we can dynamically control its presentation. The goal is to balance immediate user interaction with clean conversation flow, ensuring bash commands and their results integrate smoothly into the chat interface.

The optimal user experience requires real-time visibility of command outputs while maintaining a structured conversation layout. This means creating a mechanism that allows instant feedback during command execution, with a clear transition mechanism when the agent's turn completes.

Yes, good point. Right now:
- Bash executes and shows in chat immediately (visual position)
- But message is queued and flushed after `agent_end` (logical position)
- This mismatch is confusing

Better UX would be:
1. If streaming, show bash result in pending area (like queued messages)
2. On `agent_end`, move it to the chat at its actual position

This way the visual matches the logical order.

Want me to implement this? The changes would be:
1. `executeBash` returns whether it was deferred
2. `handleBashCommand` in InteractiveMode checks this and adds to `pendingMessagesContainer` if deferred
3. On `agent_end` event, move pending bash components to chat

Or we could make it simpler - just don't show bash output in chat until `agent_end`. User still sees streaming output in the component, it just appears in the pending area first.


no, we want to put it in pendingMessageContainer, and on next user submit, we move to chat and add to context. does that make sense?


The user wants:
1. When bash executes during streaming, show in pendingMessagesContainer
2. Keep it there until user submits their next message
3. On user submit, move it to chat and add to context

This is different from what I implemented. Currently I flush on `agent_end`. The user wants to flush on user submit.

This makes more sense because:
- Bash results are like "notes" the user made while waiting
- They get submitted along with the user's next message
- This matches the mental model better

So the flow would be:
1. Agent streaming
2. User runs `!cmd` - executes, output shown in pendingMessagesContainer, message queued
3. Agent ends - bash stays in pending area (NOT flushed)
4. User types message and submits
5. Pending bash messages moved to chat, added to context
6. User message added to chat and context
7. Agent responds

Implementation:
1. Remove the `agent_end` flush logic
2. In InteractiveMode, when user submits message, flush pending bash first
3. Show bash in pendingMessagesContainer while pending

Actually wait - let me re-read what I currently have. The `_flushPendingBashMessages` is called on `agent_end`. The user wants it called on user submit instead.

So:
1. Remove the `agent_end` handler that calls `_flushPendingBashMessages`
2. Call `_flushPendingBashMessages` in `prompt()` before processing the user message
3. InteractiveMode shows pending bash in pendingMessagesContainer

Let me implement this.

Yes, that makes more sense. The flow:

1. Agent streaming
2. User runs `!cmd` - executes, shows in `pendingMessagesContainer`, queued internally
3. Agent ends - bash stays in pending area (NOT flushed yet)
4. User submits next message
5. Pending bash moved to chat + added to context
6. User message added
7. Agent responds

Changes needed:
1. Remove `agent_end` flush - flush on `prompt()` instead
2. `handleBashCommand` adds to `pendingMessagesContainer` when streaming
3. On user submit, move pending bash components to chat

Now I need to move pending bash components to chat when user submits. Let me find where user messages are handled and add a method to flush pending bash:

bash

grep -n "onInputCallback\|getUserInput" /Users/badlogic/workspaces/pi-mono/packages/coding-agent/src/modes/interactive/interactive-mode.ts | head -10


63:	private onInputCallback?: (text: string) => void;
417:			if (this.onInputCallback) {
418:				this.onInputCallback(text);
688:	async getUserInput(): Promise<string> {
690:			this.onInputCallback = (text: string) => {
691:				this.onInputCallback = undefined;


				return;
			}

			// Normal message submission
			if (this.onInputCallback) {
				this.onInputCallback(text);
			}
			this.editor.addToHistory(text);
		};
	}

	private subscribeToAgent(): void {
		this.unsubscribe = this.session.subscribe(async (event) => {
			await this.handleEvent(event, this.session.state);
		});

I need to flush pending bash components before the callback is called. Let me add a helper method and call it:


			for (const message of queuedMessages) {
				const queuedText = theme.fg("dim", "Queued: " + message);
				this.pendingMessagesContainer.addChild(new TruncatedText(queuedText, 1, 0));
			}
		}
	}

	// =========================================================================
	// Selectors
	// =========================================================================

	/**
	 * Shows a selector component in place of the editor.
	 * @param create Factory that receives a `done` callback and returns the component and focus target
	 */
	private showSelector(create: (done: () => void) => { component: Component; focus: Component }): void {
		const done = () => {
			this.editorContainer.clear();
			this.editorContainer.addChild(this.editor);
			this.ui.setFocus(this.editor);
		};
		const { component, focus } = create(done);
		this.editorContainer.clear();
		this.editorContainer.addChild(component);
		this.ui.setFocus(focus);
		this.ui.requestRender();
	}

	private showThinkingSelector(): void {
		this.showSelector((done) => {

Let me add a method to flush pending bash components and call it before user submission:

edit

	/** Move pending bash components from pending area to chat */
	private flushPendingBashComponents(): void {

			this.pendingMessagesContainer.removeChild(component);
			this.chatContainer.addChild(component);
		}
		this.pendingBashComponents = [];

[refactor 803d4b6] Show pending bash executions in pending area, move to chat on user submit
 2 files changed, 33 insertions(+), 6 deletions(-)


Done. The flow now:

1. Agent streaming
2. User runs `!cmd` → shows in `pendingMessagesContainer`, queued internally
3. Agent ends → bash stays in pending area
4. User submits message → `flushPendingBashComponents()` moves them to chat, `_flushPendingBashMessages()` adds to context
5. User message processed
6. Agent responds with bash context available


ls

what did i just execute?


The user ran `ls` in the agent, and I executed it. But they're asking a meta question - what did they execute? They typed `ls` without the `!` prefix, so this was sent as a regular user message to me (the agent), not as a bash command.

When a user types `ls` without `!`, it's just a regular message that I (the LLM) respond to by using the bash tool. If they had typed `!ls`, it would have been a direct bash execution that bypasses the agent.

So they're testing me / asking me to clarify the difference.

You typed `ls` (without `!` prefix), so it was sent to me as a regular user message. I then used the `bash` tool to execute it.

If you had typed `!ls`, it would have been a direct bash execution that bypasses the agent entirely - just runs the command and shows output without me being involved.


ok


The user said "ok" - they understand the difference. Nothing more needed here.
