#!/usr/bin/env bash
# Begin one task of an inline plan execution in a single call: extract the
# task's brief (via subagent-driven-development's task-brief, so both skills
# share one workspace) and record BASE, the commit the task's review range is
# cut from. One tool call instead of two, because every call in an inline
# session is a turn that re-reads the whole context.
#
# Usage: task-start PLAN_FILE TASK_NUMBER
# Prints:
#   brief: <path to the task's brief file>
#   base:  <full SHA of HEAD>
