Agent Tools Today, 28 Oct 2026: OpenCode 2.2, Entire, Hallmark

OpenCode 2.2.0, published 27 Oct 2026, opened its desktop app to createable, installable and shareable plugins — marked experimental in the release notes — that can add keyed session instructions without editing the system prompt so the prompt cache survives. Entire on 26 Oct introduced what it calls "the first Git forge built specifically for agent-human collaboration," replacing pull requests with a Trail of eval scores from review agents on every push and Gates requiring human approval and passing CI before merge, and claims its Git server pushes up to 89x faster than GitHub, its own figure. The design skill Hallmark, made by Together AI for Claude Code, Codex, Cursor and OpenCode, gained 2,830 GitHub stars in a day on 28 Oct toward more than 39,000 total.
