AWS enhanced the Command Line Interface (CLI) for the Agent Toolkit by adding commands that facilitate bulk operations on agent skills. The new aws agent-toolkit check-skill-updates command compares all installed skills against current versions in the registry, while aws agent-toolkit update-skill --all updates all outdated skills in a single operation, streamlining maintenance.
Prior to this addition, users had to manage updates individually. These capabilities assist teams with extensive skill sets across various domains, ensuring coding agents operate with the latest guidance. The Agent Toolkit includes the AWS MCP Server and integrates with popular agents like Kiro, Claude Code, and Codex, with the MCP Server currently available in select AWS regions.
