What probably matters to youSection of the release
What
The per-session cap on how many forked-skill subagents you can spawn is gone from this build entirely. The rule that only one agent per forked skill runs at a time is now checked both before and after the async write that reserves it, closing a window where two launches could both get through.
Evidence
forked_skill_live_duplicate
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
