Conversation Pruning and Branching (Context Management)

Google Antigravity
1

Problem Description:
During complex development tasks, the interaction often falls into “trial-and-error” loops where the agent fails, is corrected, and tries again multiple times. This creates a long, “noisy” conversation history. This clutter not only affects the quality of subsequent responses (due to irrelevant context) but also leads to unnecessary token consumption, as the model has to process several failed iterations in every new turn.

Proposed Feature:
I would like to request features similar to those found in Google AI Studio:

  1. Selective Deletion (Pruning): The ability to delete specific user messages and model outputs to “clean” the history and resume from a successful state.

  2. Conversation Branching: The ability to fork a conversation from a specific point, allowing me to explore different implementation paths without losing or polluting the main thread.

Key Benefits:

  • Context Optimization: Keeps the model focused only on valid code and successful logic.

  • Token Efficiency: Drastically reduces the number of tokens processed by removing redundant or failed iterations.

  • Improved UX: Provides a much cleaner workspace for long-term development projects.

Huge +1 to this feature request! Coming from heavy usage of the Gemini CLI, the lack of conversation branching in Antigravity is currently my biggest pain point. In the CLI, I heavily relied on explicit checkpoints to test different implementation paths and revert seamlessly without losing context.

In Antigravity, the current rollback mechanism is strictly linear and destructive because it truncates the entire conversation history after the rollback point. Trial-and-error is a very normal part of complex engineering tasks, and losing this valuable reasoning context and exploration history is a major step backward. Having Git-like branching or forking for conversations would make Antigravity infinitely more usable.
