--- name: antigravity-mnemo description: Install, remove, or diagnose Mnemo long-term conversation memory for Google Antigravity CLI using its global Stop hook and GEMINI.md rules. --- # Antigravity Mnemo Installs the Antigravity-specific Mnemo adapter without changing project files. ## Commands ```bash node "<module_root>/install.js" node "<module_root>/install.js" --check node "<module_root>/install.js" --uninstall ``` Resolve `module_root` as the directory containing this exact `SKILL.md`; do not assume the repository is the current working directory. `ANTIGRAVITY_HOME` may point to an isolated replacement for `~/.gemini` during testing. ## Managed assets - `~/.gemini/config/hooks/olympus-save-turn.js` - named entry `olympus-antigravity-mnemo` in `~/.gemini/config/hooks.json` - marked rules block in `~/.gemini/GEMINI.md` The installer also migrates Olympus-managed Gemini CLI Mnemo assets. Unmodified legacy files are removed; modified files are preserved under `~/.gemini/_olympus-preserved/`. ## Runtime contract The Stop hook reads Antigravity's `transcriptPath`, stores the latest user and model turn in `conversations/YYYY-MM-DD-antigravity.md`, redacts `<private>` blocks, and always permits the Stop event. It does not read native transcript files during later memory searches. Use `--check` after installation. A failed check means the adapter is not verified; do not report Mnemo as active.
