A few workflow tips if you're using Gemini 4 Argon in Antigravity CLI: 1. Right-size reasoning effort (/effort) Argon thinks deeply—which is great for architecture & gnarly bugs, but overkill for mechanical edits. Keep it on medium by default, bump to high when planning/debugging, and drop to low for quick refactors. 2. One-shot model consults (/model <name> <prompt>) You don't need to stay on your heaviest model all session. Run a single prompt on Argon to diagnose a tricky bug or review a design, then automatically drop back to your faster default model. 3. Delegate to subagents & follow up with @<subagent> Offload repo exploration or test writing to subagents (coder / tester / reviewer) so your main Argon thread stays focused—type @<subagent> to message a subagent directly, or press Ctrl+K when a subagent surfaces a question (new in v1.3.6). 4. Side questions without polluting context (/btw) Need a quick syntax check mid-task? /btw answers in a side overlay without adding a single token to your main trajectory. 5. Inspect changes in-terminal (/diff) v1.3.5–1.3.6 adds a file tree, change stats, commit-message copy, and a highlighted commit tree view right in /diff.
