Internal ChangesSection of the release
An in-memory subagent spawn counter with a snapshot accessor exists but has no surface in this build.
What
A counter now tracks subagent activity for the life of the process and exposes it as a snapshot, with no user-facing surface in this build.
Details
Records spawns by requested mode (background, foreground, unset), how many started in the background, maximum nesting depth, spawns made by other subagents, and counts per agent type.
Also records completions, failures, kills split into parent/user/system, and refusals split into depth limit, concurrency limit and budget.
An agentSpawned event fires on every spawn.
