Month: 2025-12 – Delivered a targeted marketplace integration for the Anthropic ecosystem within the mckinsey/agents-at-scale-ark project. Key capabilities enable dynamic fetching of marketplace services and agents via a standardized Anthropic Marketplace JSON format, and extended the ARK CLI with comprehensive marketplace management commands (list, install, uninstall). The work includes an asynchronous marketplace service lookup, and extensive test coverage to ensure reliability across end-to-end and unit scenarios. Also, the changes restore prior improvements from PR #445 and align with related work in PRs #438 and #463, with documentation updates. Overall, this enables faster onboarding of marketplace items, safer deployment of marketplace-driven features, and stronger code quality through tests and contributor guidelines.
