# SessionStart Hook: auto-breath + dreaming on session start
# 对话开始钩子：自动浮现记忆 + 触发 dreaming
#
# On SessionStart, this script calls the Ombre Brain MCP server's
# breath-hook and dream-hook endpoints, printing results to stdout
# so Claude sees them as session context.
#
# Sequence: breath → dream → feel
# 顺序：呼吸浮现 → 做梦消化 → 读取 feel
#
# Config:
#   OMBRE_HOOK_URL  — override the server URL (default: http://localhost:8000)
#   OMBRE_HOOK_SKIP — set to "1" to disable the hook temporarily
