v0.4.0 — Antigravity, Thinking Control, and IR Alignment
Major feature release: new agent provider, unified reasoning control, structured output, and IR event alignment with llm-rosetta.
Highlights
- Antigravity CLI (agy) provider — Google's new agentic coding CLI, replacing the discontinued Gemini CLI. Full
stream-json event parser, env bridging, permission mapping. (#35)
thinking_level — Unified reasoning effort control across Claude (--effort), Pi (--thinking), OpenCode (--variant), and agy (--effort). Values: off, low, medium, high, max. (#33)- IR event alignment with llm-rosetta —
ReasoningDeltaEvent, ContentBlockStartEvent/ContentBlockEndEvent now capture thinking data that was previously dropped. (#38)
