# Antigravity Features and Practical Usage
🚀 "Think before doing" with Plan, "just do it" with Fast. Match caution and speed to the nature of each task.

Title: Plan / Fast モード

📝 Overview
Antigravity has two execution modes. Plan mode generates a detailed plan (a Plan Artifact, the Implementation Plan) before acting and implements only after approval. Fast mode skips the planning phase, interpreting your request and executing immediately. The basic split is Plan for complex tasks, Fast for minor fixes.
🔧 How It Works
The two modes behave as follows:
- Plan mode: it analyzes scope and examines files, then generates an Implementation Plan covering the goal, technology choices, steps, file modifications, and testing approach. It implements after approval and records changes in a Walkthrough.
- Interactive approval: highlight a section of the plan and comment; the agent incorporates it before implementation begins.
- Fast mode: on a "just do it" philosophy, it executes immediately without plans or waiting for approval, then reports results.
- Switching modes: use the interface controls or the keyboard shortcut (Cmd/Ctrl + .); the current mode shows in the input box.
🛠 Practical Usage
- For complex refactors or production-affecting changes, approve the plan in Plan mode before starting.
- For minor work like typo fixes, variable renames, or boilerplate, execute immediately in Fast mode.
- Combine them: do foundational work in Plan, then switch to Fast for refinements.
- Mode switches apply only to new requests; ongoing tasks continue in their original mode.
🎯 Use Cases
- Approve a large refactor as a plan Artifact in Plan mode, then implement safely.
- Knock out adding a button or fixing a typo instantly in Fast mode.
- Confirm the approach in Plan for unfamiliar tech, then move to Fast once patterns are set.
- Keep oversight via Plan for changes to production or critical systems.
⚠️ Caveats
- Fast has no planning phase to resolve ambiguity, so be specific and keep to a single task rather than bundling many.
- Fast trades thoroughness for speed and is not suited to critical changes.
- Mode switches are not retroactive; switching takes effect from the next request.
