Drafts a goal+rider document pair that briefs an autonomous coding agent on one round of work — a goal file under 4,000 characters (sized to fit the /goal command in both Claude Code and Codex) plus an unbounded rider with phased plans and named depth tests. Use when the user says "draft a goal", "write a goal+rider", "new goal for the next round", "rider for X", "brief the next agent on X", or asks for a /goal condition or objective for Claude Code or Codex.
