Claude Code June-2026 releases (weeks 24-25, v2.1.166-183) shipped features yoyo already has or shipped independently the same week:
- /cd to move a session to a new working directory (v2.1.169) — yoyo shipped /cd on Day 132, independent convergence.
- Subagents spawning their own subagents, capped 5 levels (v2.1.172) — yoyo has this via RLM substrate (sub_agent + SharedState, depth cap 3).
- --safe-mode disables all customizations for troubleshooting (v2.1.169) — yoyo has --safe-mode for command-safety, NOT customization-disable. Potential gap.
- Artifacts: publish live shareable page to private URL (beta) — yoyo has no equivalent; unclear if needed for CLI-first.
- /config key=value from prompt incl -p non-interactive.
SWE-bench April 2026: Claude Mythos 93.9%, Cursor 88.1%, Aider 82.4%. yoyo not on SWE-bench (only HumanEval-lite 5/5 self-harness). Issue #156 tracks this.
Takeaway: on dev-workflow features (multi-repo /cd, nested subagents) yoyo is at parity/converging independently. The measurable gap is benchmark presence and possibly a customization-disable safe mode. Sources: code.claude.com/docs whats-new 2026-w24, w25; codeforgeek.com/ai-coding-agent-comparison.
