#!/usr/bin/env bash
# Human-in-the-loop reproduction loop.
# Generated by the diagnosing-bugs skill (/skill:diagnosing-bugs).
# The agent copies this file and edits the steps below; the human runs it.
# The human runs the script in their own terminal and follows its prompts.
# The agent never runs it, in whole or in part: it only checks it with
# `bash -n` or `shellcheck`, and reads the Captured block the human pastes back.
#
# Usage (the human, in their own terminal):
#   bash hitl-loop.template.sh
#
# Two helpers:
#   step "<instruction>"          → show instruction, wait for Enter
#   capture VAR "<question>"      → show question, read response into VAR
#
# At the end, every value `capture` read is printed as KEY=VALUE, whatever its
# name; paste that block back to the agent. Record every observation with
# `capture`, so the block carries it; edit only between the markers.
#
# `capture` prints its value back to the terminal, and the pasted block reaches
# the agent, so capture observations, never a password, token or other secret,
# and leave signing in to the user as a `step`.

set -euo pipefail

# The names `capture` filled and their values, in order, for the Captured block.
# Values are kept here too, so a VAR named like a helper's local still prints.
