Jan 1, 2026January 2026 (mckinsey/agents-at-scale-ark): Focused on delivering observability enhancements, deployment reliability hardening, and security updates, while advancing core features to improve tool usage visibility, data exploration, and overall platform resilience. Key outcomes include: Delivered Dashboard Chat: Tool Calls Visibility and Debug UI, including tool-call context propagation to agents, UI padding for readability, and a debug toggle for inspecting tool interactions. Implemented MCP Server URL editing with whitespace normalization to prevent connection failures. Added Broker Data View: Sessions tab with grouped raw data by session and timing, along with corrected timestamps that reflect actual data time or fall back to current date. Replaced deprecated mcp-filesystem with a new S3-compatible file-gateway service for storage and REST access. Hardened Ark install and broker deployment reliability by adding service-status checks and a restart hook to detect the broker post-deployment, reducing upgrade failures. Improved security and dependency hygiene with Node.js base image updates to patch CVEs, protobuf and tar vulnerability mitigations, and Terraform module updates. Boosted test stability by removing flaky external API calls and replacing them with local mocks, and by relaxing unstable timeouts to reduce false negatives. These changes collectively improve deployment reliability, observability, security, and development efficiency, delivering tangible business value through lower risk, faster QA cycles, and better tool usage transparency.
