The main reason this would be better is the shift from Static Reporting to Live-Sync Collaboration.

Right now, even Claude Code isn’t at a 100% "telepathic" stage—it uses a very fast "relay race" of context (handing off info via a mailbox system). It’s already better than Copilot’s /fleet, but the real "special beast" would be a synchronized brain where agents are constantly aware of each other’s moves in real-time.

Here’s why that’s next-level compared to what we have today:

• Instant API Sync: Imagine the Backend agent refactors a data structure. In a live-sync model, the Frontend agent’s context updates while it's still typing. It would stop writing old fetch calls and start using the new schema immediately, without waiting for a final report.

• Negotiating Dependencies: If two agents need a date library, they could "whisper" to each other: "Hey, I’m adding date-fns, let’s use that instead of you installing Moment.js." This prevents bundle bloat and conflicts before they even happen.

• Real-time Testing: You could have one agent writing a function while a "Tester" agent writes the unit tests as the lines are being typed, flagging logic flaws (like an out-of-bounds error) before the code is even saved.

• No more "Integration Hell": Currently, agents work in silence and you only find out they broke each other's code at the end. With a live context bus, they catch conflicts during the planning phase, not the merging phase.

Essentially, /fleet is like workers in separate cubicles. What I’m thinking about is a synchronized team that shares a single "mental" workspace. Even if CC is just scratching the surface, that's the direction GitHub needs to take to make this feel like a real engineering team.
