Pull request overview
Adds first-class PreToolUse hook support for the Google Antigravity CLI (“agy”), enabling RTK to intercept run_command tool calls and rewrite commands via the existing hook engine.
Changes:
- Adds a new
rtk hook antigravitysubcommand and Antigravity agent targeting/dispatch wiring. - Implements Antigravity hook installation/uninstallation, including patching
hooks.json(local.agents/hooks.jsonand global~/.gemini/config/hooks.json) and generating a rules file for local projects. - Extends hook detection/telemetry and replaces
str::floor_char_boundaryusage with a stable-compatible helper.
