July 2025 (docker/compose-for-agents): Focused on documenting quality and demonstration clarity for a multi-agent architecture. Key deliverables include correcting a Brave Search reference and the correct configuration path in the main README (and related docs), and introducing an Agent System classification in the demos table to distinguish Single Agent vs Multi-Agent demos, with Agno clearly identified as Multi-Agent. These changes improve onboarding, reduce user confusion, and align docs with the actual system behavior. No production code changes were required this month; all work was concentrated on documentation and demo materials, carrying low runtime risk.
