#!/usr/bin/env bash
# Generates harness-specific context files from .context/PROJECT.md
# Project-level script — run from a project directory.
#
# For Claude Code: generates project-only CLAUDE.md (it inherits root via tree walk)
# For everything else: concatenates root AGENT.md + project PROJECT.md
#
# Usage: ./scripts/context-sync.sh [adapter...]
# Task:  task context:sync
#
# Override root context: ROOT_CONTEXT=~/dev/.context/AGENT.md ./scripts/context-sync.sh
