## Agent Teams Architecture Corrections
Based on official sources (Addy Osmani blog, Feb 2026):
**Major changes**:
- Add mailbox system documentation (peer-to-peer messaging)
- Correct communication model: not only team lead synthesis
- Update diagrams to show peer-to-peer arrows
- Clarify context isolation vs message sharing
- Add 7 sections with source attribution
- Add documentation update note (2026-02-09)
**Key correction**: Agents communicate via mailbox system (direct
peer-to-peer + team lead synthesis), not only hierarchical reporting.
**Files modified**:
- guide/workflows/agent-teams.md (+72 -19): 7 major corrections
- CHANGELOG.md: Document session handoff template addition
- guide/architecture.md: Architecture clarifications
- guide/ultimate-guide.md: Cross-references updates
