+### Shell completion
+`swdd~cli-shell-completion~1`
+
+Status: approved
+
+When the user starts typing an Ankaios CLI command, the zsh and bash shell shall propose completions for arguments including dynamic completions for workload names, object field masks and agents.
+
+Rationale:
+A user's productivity is increased when command completions are provided which reduces lookups for the user.
+
+Comment:
+If possible more shells shall be supported as well.
