AWS cli documentation change
Summary
File renamed from devops-agent/describe-support-level.md to securityagent/delete-membership.md with complete content replacement. Changed from describing support levels to documenting a command that removes members from agent spaces.
Security assessment
This change documents a new AWS CLI command for removing memberships (users or agent spaces) from security agent spaces. While this is a security-related command for access control management, there is no evidence in the diff that it addresses a specific security vulnerability or incident. The change appears to be routine documentation for a new security feature.
