Antigravity CLI v1.1.6 Adds Custom Agents Defined in Plain Markdown Files

Havoptic·medium signal

Released 2026-07-24, Antigravity CLI v1.1.6 lets you define custom agents through simple Markdown files rather than structured config — the same authoring model Claude Code uses for subagents and skills. The two prior releases added an `/effort` command for on-the-fly reasoning depth (v1.1.5, 2026-07-21) and multi-command chaining in a single prompt so sequences like `/plan /grill-me` run in order (v1.1.4, 2026-07-18). Markdown-defined agents are now table stakes across CLIs, which makes agent definitions increasingly portable between harnesses.
