What changed
plugins_for_configspanskills_for_configspanWhy
session_init.plugin_skill_warmupcurrently combines plugin loading and skill loading, which makes cold-start traces unable to identify which phase dominates. These child spans preserve the existing aggregate while making the two costs independently visible.Context: https://openai.slack.com/archives/C0ARA9GF5D4/p1781639496496439?thread_ts=1781202444.891669&cid=C0ARA9GF5D4
Impact
This is observability-only. It does not change plugin or skill loading behavior.
Validation
