FUTURE: Implement observer as agent team — auto-review without second terminal

[KlementMultiverse]

Vision

Use Claude Agent SDK agent teams to run observer as a parallel agent:

• Builder agent builds (Phase 0-5)
• Observer agent auto-reviews artifacts in real-time
• No second terminal needed
• Observer writes .observer-reviews.log automatically

Current State

• Observer system scripts exist (check, approve, gate)
• Communication via files (.observer-reviews.log)
• Requires manual second terminal
• CodeRabbit handles PR review (required)

When to Implement

After all 57 steps are battle-tested and the observer protocol is proven via manual use.
