What

3 new Claude Code skills + 4 new CLIs landed (gstack-inspired): taste-memory, document-release, bench-model + aj-checkpoint. All claude-code-session-local, not new MCP servers. EA-relevant: aj-doc-release detects product-doc drift on EA-managed projects when AJ ships changes; aj-checkpoint provides crash-recovery for long EA-spawned dev sessions.

Why

If EA spawns claude-code for product-repo work (r-taskflow/r-dash/runwal-bkc updates), the new doc-drift detector and checkpoint CLI are immediately available. Mostly augmentation — no EA workflow change required.

Action Required

Awareness only. No routing change needed unless EA explicitly orchestrates dev work that benefits from these CLIs.
