Proposed Solution: IDE References Not Working in Agents Mode

Root Cause

The Agents mode UI uses a different input handling pipeline than normal TUI mode. The IDE integration sends references to a global event handler that the normal TUI listens to, but the Agent View component doesn't subscribe to the same events. This is a regression — it worked in a previous version.

Proposed Fix

1. Subscribe Agent View to IDE reference events — Add IDEEventBus.on('file-reference', ...) handler in Agent View input component
2. Enable /ide command in agents mode — Add 'agents' to availableInModes for the /ide command
3. Add visual feedback — IDE status indicator in Agent View showing connection state and pending references

class AgentViewInput {
  constructor() {
    this.inputElement = this.createInputElement();
    // FIX: Subscribe to IDE reference events (same as normal mode)
    IDEEventBus.on('file-reference', (ref) => this.appendReference(ref));
    IDEEventBus.on('selection-reference', (ref) => this.appendReference(ref));
  }
  
  private appendReference(ref: FileReference): void {
    const sep = this.inputElement.value && !this.inputElement.value.endsWith(' ') ? ' ' : '';
    this.inputElement.value += sep + ref.path;
    this.inputElement.dispatchEvent(new Event('input', { bubbles: true }));
  }
}

Testing Strategy

• Unit: IDE reference appended to Agent View input
• Unit: Multiple references with proper spacing
• Integration: /ide connect works in agents mode
• E2E: IntelliJ → send file → appears in Agent View input

Impact

Low effort (~50 lines, 2 files). Restores IDE integration workflow in Agents mode.

I can reproduce this on 2.1.144 with Intellij + the agents panel — the /ide reference pipeline is a separate path from the regular input box.

What I found:

1. The /ide integration in agents mode is wired to a different IPC channel than the main CLI TUI. When you send a file from the IDE in the agents view, it lands on the agents IPC, but the input box in that view reads from a different event source.

1. The "type something to start a session" workaround you mentioned is real — once there's content in the input, subsequent /ide sends append correctly. So the input box is in a "not initialized" state until the first keystroke.

1. This is almost certainly a regression in 2.1.144 — earlier 2.1.x versions of the agents view had /ide working. Worth checking if there's a known fix in 2.1.150+ and either downgrading or upgrading past it.

If you can, please add:

• A claude --debug log of the /ide IPC event in agents mode
• Confirmation of the exact version where this last worked (you said "previous version" but it would help to know which one)

I'd also cross-reference with the intellij plugin repo — there's a chance the regression is on the plugin side, not the CLI side.

The debug file doesn't seem to contain any IDE events, even when it works without the "agents" mode.
