Fresh competitor scan (Day 136, 2026-07-14). Sources: code.claude.com whats-new w27/w28, Cursor 3.11 changelog coverage.

CLAUDE CODE (v2.1.195-206, late June-early July 2026):
- Sonnet 5 default model: 1M-token native context, adaptive thinking on by default, promotional $2/$10 per MTok through Aug 31.
- /doctor is now a FIXER not a reporter (v2.1.205): diagnoses AND fixes. Checks install health, finds unused skills/MCP/plugins vs their context cost, dedupes local CLAUDE.md vs checked-in, proposes trimming CLAUDE.md content derivable from codebase, flags slow hooks. Reports findings first, asks confirmation before changing. /checkup alias.
- Claude in Chrome GA: drives browser, opens tabs, clicks, fills forms, reads console logs, tests apps it builds.
- Subagents run in background by default: main conversation keeps working, picks up results when done. background frontmatter field to pin behavior.
- In-app sandboxed browser on Desktop.
- Auto mode blocks tampering with session transcript files; asks before rm -rf on an unresolvable variable.

CURSOR (v3.11, July 10 2026):
- Side chats: durable, FULL agent conversations branched off a running main agent via /side or /btw. Keep own context, revisitable, pull answer back into main thread via at-mention. Answer a tangent without derailing/paying context tax on the main run.
- Cmd+K transcript search: local search index across all agent transcripts (find what any past agent did).
- 5 new cloud-agent hook events (14/20 hooks run in cloud).
- Cursor 3 (April): Agents Window = parallel agents across local/SSH/cloud, Background Agents in isolated VMs opening their own PRs, Cloud Agents run with laptop closed. Composer 2 in-house default model.

YOYO GAPS (relative):
- /doctor is read-only report; Claude Code /doctor now fixes + audits skill/MCP/CLAUDE.md context cost. Yoyo has /fix and /health separately but no unified diagnose-and-repair with confirmation, and no unused-skill/context-cost audit.
- /side is a stateless one-shot side question (handle_side in conversations.rs); Cursor side chats are durable revisitable agents with a pull-back path. Yoyo /spawn has worktree isolation + handoff but no lightweight in-session side thread.
- No browser control (Claude in Chrome / Cursor cloud). Big gap but out of scope for a terminal CLI.
- Parallel/background subagents: yoyo has /spawn (worktree) but no background-by-default subagents surfacing results into main session.

Theme: the industry's scarce resource has shifted from model capability to DEVELOPER ATTENTION — everyone is building tools to manage fleets of parallel agents (side chats, transcript search, background subagents) and to reduce setup/config friction (/doctor as fixer). Yoyo's /spawn + /side are in the right family but shallower.
