Plan Goal

Bridge the active plan to Claude Code's /goal primitive.

Steps:

1. Resolve the active plan: prefer ${PLAN_ID} env var, then .planning/.active_plan, then newest .planning/<dir>/, then legacy ./task_plan.md.
2. Read the resolved task_plan.md.
3. Derive a goal condition from the plan content:
   • Default: "all phases in task_plan.md report Status: complete and check-complete.sh reports ALL PHASES COMPLETE"
   • If user passed an argument: use that as an additional clause (e.g., /plan-goal until all tests pass)
4. Issue Claude Code's /goal <condition> with the derived text.
5. Confirm to the user: print the goal condition + the active plan ID + remind that /goal clear cancels.

If task_plan.md does not exist, refuse and direct user to run /plan first.

Why this exists:

/goal runs the agent until a small fast model confirms the condition is met. It evaluates the transcript only, not files. By deriving the condition from the plan file, this command turns the file-based plan into a measurable termination criterion for /goal, so the loop terminates when the plan is actually done, not when the conversation looks done.

Notes:

• /plan-goal does not replace /goal. It composes with it. Users can still run /goal "any text" directly.
• The derived condition stays under the 4000-char limit /goal enforces by quoting only phase headers + acceptance criteria, not full task body.
• Combine with /plan-loop for a "babysit until done" workflow: /plan-loop cadence + /plan-goal termination.
