Lanes: Master & Slave

The window has two lanes:

• Master (left) — plan & review. Understands your goal, writes a short plan, and reviews the resulting code.
• Slave (right) — write & execute. Actually creates and edits files in your project.

Each lane independently runs Claude, Codex, or DeepSeek — mix and match (see Backends and Connection).

Modes

Switch at the top of the window.

Solo mode

Left and right are two separate conversations. Chat with one lane at a time — e.g. just talk to Codex to edit files, or just ask Claude to plan. The slave lane writes files; the master lane plans/answers.

Dual mode (automatic orchestration)

You give one goal and the lanes run the whole loop themselves:

You: "Build a dark-mode to-do web page"
      │
      ▼
  Master: plan ─▶ Slave: write files ─▶ Master: review the diff
                       ▲                          │
                       └──── revise (up to 3×) ◀──┘
                                                  │
                                                  ▼
                                               ✅ done

• The master plans → the slave executes (real file edits) → the master reviews the change → if it doesn't pass, the slave revises (up to 3 rounds) → ✅ done.
• No clicks required end to end.

Interjection ("随时插话")

While a turn is running you can type anytime to add or correct instructions. Your message is folded into the current task instead of starting a new one.

Live preview

The slave lane has a Preview tab with an embedded browser. When a project gains an index.html (e.g. after the agent builds a page), it renders there and refreshes automatically.

History & search

Conversations are auto-saved. The History view lists past sessions; full-text search finds any message across all conversations, and you can resume a session to continue with context.
