Task Start

1#!/usr/bin/env bash
2# Begin one task of an inline plan execution in a single call: extract the
3# task's brief (via subagent-driven-development's task-brief, so both skills
4# share one workspace) and record BASE, the commit the task's review range is
5# cut from. One tool call instead of two, because every call in an inline
6# session is a turn that re-reads the whole context.
7#
8# Usage: task-start PLAN_FILE TASK_NUMBER
9# Prints:
10#   brief: <path to the task's brief file>
11#   base:  <full SHA of HEAD>
