[BUG] Regression: Claude Code developer desktop UI removed; Cowork is not an equivalent replacement

What's Wrong?

The Claude Desktop app no longer provides a dedicated Claude Code developer UI.

Only Claude Cowork is available as the agentic desktop interface, and it does not support developer workflows with the same usability, interaction model, or ergonomics that the previous Claude Code desktop experience offered.

As a result, Claude Code is effectively CLI-only, despite previously having a significantly more user-friendly desktop UI for coding tasks.

Why this is a regression
The prior Claude Code desktop UI was significantly more efficient for:

• structured coding tasks
• longer interactive sessions
• iterative development workflows

Cowork is optimized for non‑coding, document- and file‑oriented tasks and lacks parity for developer use cases.
Removing a usable Claude Code desktop experience materially degrades usability, even though the underlying agent capabilities still exist via CLI.

This represents a usability regression, not just a product repositioning.

What Should Happen?

Claude Code should have a first‑class desktop UI suitable for development workflows, or a clearly defined developer mode within the desktop app that restores the prior Claude Code experience.
Cowork should not be treated as an equivalent replacement for developer-focused usage.

Error Messages/Logs

Steps to Reproduce

1. Install or update to the latest Claude Desktop app
2. Open the app
3. Observe that agentic functionality is limited to Cowork
4. Attempt to access a developer-focused Claude Code desktop interface (not available)

Observed behavior

• No Claude Code desktop UI option exists
• Cowork is presented as the only agentic desktop experience

Expected behavior

• Claude Code remains available as a first-class desktop experience
• or a developer-specific mode exists in the desktop app
