oh-my-openagent v4.19.0 release notes

🚀 oh-my-openagent v4.19.0 — Open models just took the crown

This release ships with first-class support for Kimi K3, the 2.8-trillion-parameter open-weight frontier model from Moonshot AI that is now beating Claude Fable 5 on the Arena.ai Frontend Code leaderboard. OSS must win — and with K3, it just did.

🤖 Kimi K3 is a first-class citizen

Sisyphus, Sisyphus-Junior, and Atlas now carry dedicated Kimi K3 prompt variants calibrated for K3's reasoning style, plus model-family detection and fallback routing in model-core. Whether you route through OpenRouter or Moonshot's API directly, omo recognizes K3 and picks the right prompts automatically.

🎯 Goals replace Ralph Loop

The legacy Ralph Loop wiring is gone. In its place: a clean Goal feature with state, persistence, parser, config migration, and a /goal command. Existing Ralph Loop configs migrate automatically, so nothing breaks.

🛠️ Senpi task engine gets serious

The Senpi task system received a deep reliability pass: residency claims release correctly when tasks are marked lost, TTL cleanup is wired into session start with proper live-handle guards, the record store caches and reuses file descriptors, and the lead poller scans incrementally. These changes make long-running multi-agent workflows noticeably more stable.

🔌 Senpi platform expansion

omo-senpi now ships with the hyperplan adversarial-planning skill, a Senpi session platform for Boulder state, codegraph MCP registration, and default shared + local skills out of the box. Start-work continuation is also wired for Codex.

🐛 Lazycodex / Codex reliability fixes

Codex users get fixes for V2 thread-cap preservation, stricter ulw-plan parsing and validation, Playwright MCP custom-arg support, and safer codegraph git-marker handling.

🌍 Why this release matters

Kimi K3 is the largest open-weight model ever released, and independent benchmarks place it ahead of Claude Opus 4.8 and GPT-5.5 while trading blows with Claude Fable 5 and GPT-5.6 Sol. The frontier is no longer a closed garden. This release makes sure omo users can ride that wave the moment it hits.

📝 A personal note from the maintainer

Today I did not use Claude Opus 4.8 once. Kimi K3 and the open-weights wave handled the work.
