Let me check the CompactionEntry type:

bash

cd /Users/badlogic/workspaces/pi-mono && grep -n "CompactionEntry\|tokensAfter\|tokensBefore" packages/coding-agent/src/session-manager.ts | head -20


49:export interface CompactionEntry {
54:	tokensBefore: number;
63:	| CompactionEntry;
125:export function getLatestCompactionEntry(entries: SessionEntry[]): CompactionEntry | null {
128:			return entries[i] as CompactionEntry;
170:	const compactionEvent = entries[latestCompactionIndex] as CompactionEntry;
354:	saveCompaction(entry: CompactionEntry): void {


The CompactionEntry has `tokensBefore` but not `tokensAfter`. Let me check what properties it has:


export interface CompactionEntry {
	type: "compaction";
	timestamp: string;
	summary: string;
	firstKeptEntryIndex: number; // Index into session entries where we start keeping
	tokensBefore: number;
}

/** Union of all session entry types */
export type SessionEntry =
	| SessionHeader
	| SessionMessageEntry
	| ThinkingLevelChangeEntry
	| ModelChangeEntry
	| CompactionEntry;

// ============================================================================
// Session loading with compaction support
// ============================================================================

[545 more lines in file. Use offset=69 to continue]


I see, there's no `tokensAfter`. Let me update the CompactionResult interface to match what's actually available:

edit

/** Result from compact() or checkAutoCompaction() */
export interface CompactionResult {
	tokensBefore: number;
	tokensAfter: number;
	summary: string;
}

/** Result from compact() or checkAutoCompaction() */
export interface CompactionResult {
	tokensBefore: number;
	summary: string;
}

slight steering: why does unsubscribe clear the event listeners? i would assume a user of agentSession would setup their listener once, then assume agent session holds on to them. if we do e.g. compact or branch or whatevr and reset or temporarily un and re-subscribe, those event lsiteners should still be there, no?


The user is right. The current design has a flaw:

1. User calls `session.subscribe(myListener)` - adds listener to `_eventListeners`
2. Some internal operation calls `unsubscribeAll()` - clears all listeners!
3. Then `resubscribe()` is called - but `_eventListeners` is now empty
4. User's listener is gone

The correct design should be:
- `_eventListeners` stores the user's listeners and persists across internal operations
- `unsubscribeAll()` should only disconnect from the agent, not clear the listeners
- `resubscribe()` reconnects to the agent and uses the existing listeners

Let me fix this. The `unsubscribeAll()` should NOT clear `_eventListeners`, only disconnect from the agent.

Actually, looking at the code more carefully:
- `unsubscribeAll()` clears `_eventListeners` - this is wrong
- `resubscribe()` expects `_eventListeners` to still have listeners

The fix is simple: `unsubscribeAll()` should only clear `_unsubscribeAgent`, not `_eventListeners`.

But wait, there's also a use case where someone might want to fully clean up. Maybe we need two methods:
1. `_disconnectFromAgent()` - internal, just stops the agent subscription but keeps listeners
2. `dispose()` or `cleanup()` - public, for full cleanup when done with the session

Let me just fix `unsubscribeAll()` to not clear the listeners, since that's what the user is asking about.

You're absolutely right. That's a bug in my design. `unsubscribeAll()` should only disconnect from the agent, not clear the user's listeners. Let me fix that:

	/**
	 * Unsubscribe from agent entirely and clear all listeners.
	 * Used during reset/cleanup operations.
	 */
	unsubscribeAll(): void {
		if (this._unsubscribeAgent) {
			this._unsubscribeAgent();
			this._unsubscribeAgent = undefined;
		}
		this._eventListeners = [];
	}

	/**
	 * Re-subscribe to agent after unsubscribeAll.
	 * Call this after operations that require temporary unsubscription.
	 */
	resubscribe(): void {
		if (this._unsubscribeAgent) return; // Already subscribed

		this._unsubscribeAgent = this.agent.subscribe(async (event) => {
			for (const l of this._eventListeners) {
				l(event);
			}

			if (event.type === "message_end") {
				this.sessionManager.saveMessage(event.message);

				if (this.sessionManager.shouldInitializeSession(this.agent.state.messages)) {
					this.sessionManager.startSession(this.agent.state);
				}

				// Check auto-compaction after assistant messages
				if (event.message.role === "assistant") {
					await this.checkAutoCompaction();
				}
			}
		});
	}

	/**
	 * Temporarily disconnect from agent events.
	 * User listeners are preserved and will receive events again after resubscribe().
	 * Used internally during operations that need to pause event processing.
	 */
	private _disconnectFromAgent(): void {
		if (this._unsubscribeAgent) {
			this._unsubscribeAgent();
			this._unsubscribeAgent = undefined;
		}
	}

	/**
	 * Reconnect to agent events after _disconnectFromAgent().
	 * Preserves all existing listeners.
	 */
	private _reconnectToAgent(): void {
		if (this._unsubscribeAgent) return; // Already connected

		this._unsubscribeAgent = this.agent.subscribe(async (event) => {
			for (const l of this._eventListeners) {
				l(event);
			}

			if (event.type === "message_end") {
				this.sessionManager.saveMessage(event.message);

				if (this.sessionManager.shouldInitializeSession(this.agent.state.messages)) {
					this.sessionManager.startSession(this.agent.state);
				}

				// Check auto-compaction after assistant messages
				if (event.message.role === "assistant") {
					await this.checkAutoCompaction();
				}
			}
		});
	}

	/**

	 * Call this when completely done with the session.
	 */
	dispose(): void {
		this._disconnectFromAgent();
		this._eventListeners = [];

export { AgentSession, type AgentSessionConfig } from "./agent-session.js";

Good, BashResult is already exported. Let me also export the other types from agent-session:

export { AgentSession, type AgentSessionConfig } from "./agent-session.js";

export {

 create mode 100644 packages/coding-agent/src/modes/index.ts


Excellent progress! We've completed WP1-WP13. Let me show a summary:

cd /Users/badlogic/workspaces/pi-mono && echo "=== Files created ===" && find packages/coding-agent/src/core packages/coding-agent/src/modes -name "*.ts" | sort && echo "" && echo "=== Line counts ===" && wc -l packages/coding-agent/src/core/*.ts packages/coding-agent/src/modes/*.ts


=== Files created ===
packages/coding-agent/src/core/agent-session.ts
packages/coding-agent/src/core/bash-executor.ts
packages/coding-agent/src/core/index.ts
packages/coding-agent/src/modes/index.ts
packages/coding-agent/src/modes/print-mode.ts
packages/coding-agent/src/modes/rpc-mode.ts

=== Line counts ===
     885 packages/coding-agent/src/core/agent-session.ts
     177 packages/coding-agent/src/core/bash-executor.ts
      14 packages/coding-agent/src/core/index.ts
       7 packages/coding-agent/src/modes/index.ts
      69 packages/coding-agent/src/modes/print-mode.ts
      84 packages/coding-agent/src/modes/rpc-mode.ts
    1236 total


Good progress. We now have:

- **AgentSession** (885 lines) - the shared core with all agent/session logic
- **bash-executor** (177 lines) - unified bash execution
- **print-mode** (69 lines) - single-shot mode
- **rpc-mode** (84 lines) - headless JSON protocol

Next is WP14: Create main-new.ts. This is the bigger work package where we wire everything together. Given the complexity, should I continue with WP14 now, or would you like to stop here and review what we have so far?


i reviwed what we have, it's good. continue


Great, the user wants me to continue. WP14 is about creating main-new.ts - a new version of main.ts that uses AgentSession and the new mode modules.

Let me copy main.ts to main-new.ts and then modify it to:
1. Remove `runSingleShotMode()` function (use print-mode.ts)
2. Remove `runRpcMode()` function (use rpc-mode.ts)
3. Remove `executeRpcBashCommand()` function (use bash-executor.ts)
4. Create `AgentSession` instance after agent setup
5. Pass `AgentSession` to mode functions

For now, interactive mode will still use TuiRenderer directly - that will be refactored in WP15.

Let's do WP14: Create main-new.ts. First, let me copy main.ts and then modify it:


(no output)


Now let me read main-new.ts and start modifying it. First, let me see the imports and the functions we need to remove:

Good. Now I'll delete all three functions (runSingleShotMode, executeRpcBashCommand, runRpcMode). They span from line 811 to line 1112. Let me do this carefully:


			const errorMessage = error instanceof Error ? error.message : "Unknown error occurred";
			renderer.showError(errorMessage);
		}
	}
}

async function runSingleShotMode(
	agent: Agent,
	_sessionManager: SessionManager,
	messages: string[],

edit

	}
}

async function runSingleShotMode(

			const errorMessage = error instanceof Error ? error.message : "Unknown error occurred";
			renderer.showError(errorMessage);
		}
	}
}

// runSingleShotMode removed - replaced by runPrintMode from ./modes/print-mode.ts

Actually, let me just delete them entirely. Let me find the exact boundaries:

The deleted functions are:
- `DELETED_runSingleShotMode` at 815-863
- `executeRpcBashCommand` at 869-944
- `runRpcMode` at 946-1116

Let me read the exact text to delete:
