AWS Open Sources Kiro Crew for Asynchronous Coding Agents

Amazon announced Kiro Crew, an open-source system for orchestrating multiple Kiro coding agents across sessions, tools, and tasks. The workspace lets developers assign asynchronous coding work, such as incident investigation, ticket triage, migrations, and pull request monitoring, so it continues without active supervision.

Proven Internally at Amazon

Kiro Crew was developed internally at Amazon under the name MeshClaw and, according to the announcement, has been adopted by more than 39,000 developers. The system supports persistent multi-session work through shared memory, reusable skills, scheduled jobs, concurrent agents, and purpose-built apps. Agents can retain project context, run tasks while developers are away, delegate work to subagents, and integrate with external tools through MCP and webhooks.

Agent Client Protocol

Kiro Crew orchestrates agents through the Agent Client Protocol, or ACP, giving live visibility into each agent's plan, tool calls, approval gates, and results. The Activity view shows work as it happens, and the platform includes sensitive-path blocking and can be customized through MCP, apps, orchestration, and reusable skills. Skills built for other standards-based agent platforms can be reused without modification.

Availability and License

The project runs on the Kiro CLI and reuses existing .kiro configurations, including steering files, skills, and custom agents. It is released under the Apache 2.0 license and supports macOS, Linux, and Windows, with integrations for Slack, Telegram, and WeCom. Amazon engineers will initially maintain the project, and external maintainers can join as contributors emerge, according to InfoQ's coverage of the release.
