# Per ADR-0015, apm.yml is the authoring source and .claude-plugin/plugin.json is
# compiled output with no skills/hooks/mcpServers/agents pointer fields (apm's plugin.json
# builder deliberately omits them -- Claude Code auto-discovers those convention
# directories, so listing them would be redundant/invalid). This script no longer checks
# those fields; that's now scripts/sync-plugin-content.sh --check's job (drift between
# .apm/ and the flat plugin-root mirror), wired as its own pre-push hook.
