# Consolidated prerequisite checking script
#
# This script provides unified prerequisite checking for Spec-Driven Development workflow.
# It replaces the functionality previously spread across multiple scripts.
#
# Usage: ./check-prerequisites.sh [OPTIONS]
#
# OPTIONS:
# --json Output in JSON format
# --require-tasks Require tasks.md to exist (for implementation phase)
# --include-tasks Include tasks.md in AVAILABLE_DOCS list
# --paths-only Only output path variables (no validation)
# --help, -h Show help message
#
# OUTPUTS:
# JSON mode: {"FEATURE_DIR":"...", "AVAILABLE_DOCS":["..."]}
# Text mode: FEATURE_DIR:... \n AVAILABLE_DOCS: \n ✓/✗ file.md
# Paths only: REPO_ROOT: ... \n BRANCH: ... \n FEATURE_DIR: ... etc.

EXAMPLES:
# Check task prerequisites (plan.md required)
./check-prerequisites.sh --json
# Check implementation prerequisites (plan.md + tasks.md required)
./check-prerequisites.sh --json --require-tasks --include-tasks
# Get feature paths only (no validation)
