# Fences every agent integration's generated output against what is
# checked in — across all platforms (not Claude-only), on every PR (not
# release-only). Two complementary checks run:
#
#   1. The all-platform render golden (go test) byte-compares every
#      adapter's rendered MCP config / instructions / hooks / routing
#      blocks against committed goldens.
#   2. A structural --check that every adapter still emits a gortex
#      registration.
#
# Both build the pure-Go CLI (no -tags llama), so the gate runs on a
# stock runner. When a check fails on an intended change, regenerate and
# commit the goldens:
#   go test ./cmd/gortex -run TestAgentsRenderGolden -update-agent-render
