Proposal: Setup for Antigravity

[thomasgiroire]

Hi all,

I've been using RTK to optimize my sessions with Antigravity, trying to extending context window longevity.

However, I encountered a major friction point: even with strict instructions, LLMs often "drift" and default to raw commands (like git status or npm test) instead of prefixing them with rtk.

To solve this, I create (using the agent itself!) a script that makes RTK the standard for the agent , on MacOS.

🚀 Technical Breakdown:

• Isolated Shims:

  • A setup script generates lightweight proxy shims in ~/.config/rtk-shims/bin/ for every command supported by rtk help.
  • exemple :
    #!/bin/zsh
# RTK Shim for git
export PATH=$(echo "$PATH" | /usr/bin/sed -E "s|:[^:]*/rtk-shims/bin:?|:|g; s|^[^:]*/rtk-shims/bin:?||")
exec rtk git "$@"

• Context-Aware PATH:

  • It injects this folder into the $PATH (via ~/.zshrc), but the injection is strictly wrapped in a condition that detects AI-specific environment variables (like $ANTIGRAVITY_AGENT, $CURSOR_SESSION_ID, or $VSCODE_INJECTION).

• Bypassing:

  • The shims are context-aware. During real-world production testing, I found that some tools (like certain database CLI migrations or interactive tools) can fail when wrapped by RTK. The script implements a bypass pattern. : for instance, for supabase.

• Global Agent "Brain" Config:

  • The script automatically appends instructions to the agent's global configuration (e.g., ~/.gemini/GEMINI.md). This informs the agent it has "RTK superpowers" at the OS level and tells it to use absolute system paths (e.g., /usr/bin/git) as a safety fallback if a shim behaves unexpectedly.

• Infinite Loop Prevention:

  • Shims dynamically remove themselves from the $PATH before execution to prevent recursion.

✨ The Result:

1. For the Agent, every native command is automatically and transparently optimized across ALL projects.
2. But your personal terminal remains 100% native and undisturbed.

I just found this PR, I think my idea is no longer useful 😅 ...
