/planning
Command removed since 1.1.0 per changelog/modes page, replaced by /plan prefix
/planning was originally a slash command from the "Configurations" category that activated a mode in which the agent first drafts a plan across multiple turns before executing, instead of acting directly β intended for complex engineering tasks with many dependencies.
Important: according to the dedicated Antigravity CLI page on execution modes as well as the official changelog, /planning (together with the old /fast) was removed in version 1.1.0 as a "vestigial command". It was replaced by a unified mode system: either you press Shift+Tab to cycle between the modes default, accept-edits, and plan, or you prefix your prompt with /plan so the CLI automatically switches to plan mode.
Note: the general command reference page still lists /planning as an active command with the same old description β this contradicts the dedicated modes page and the changelog and looks like an outdated piece of documentation.
π THE SAME TASK (βPLAN MODE (PLAN FIRST, THEN ACT)β) ON OTHER PLATFORMS
- Claude Code: /plan
- Codex CLI: /plan
- Cursor CLI: /plan
- Aider: /architect
β WHEN TO USE IT?
Have a multi-step task planned
Prefix your prompt with /plan before a larger refactoring task (successor to the old /planning)
Switch between execution modes
Cycle between default, accept-edits, and plan with Shift+Tab, instead of typing the removed /planning
β WHEN NOT TO?
Typing /planning like before
According to the modes page and changelog, the command has been treated as a removed legacy command since version 1.1.0.
Better: Prefix the prompt with /plan or switch modes with Shift+Tab
Having a trivial single action planned
According to the modes page, planning overhead isn't worth it for trivial actions like typo fixes.
Better: Choose fast mode via Shift+Tab (the old /fast was also removed in 1.1.0 per the changelog)
