# 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.

+ 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.

+ ## Rules and past-work lookup

+ The global policy source is [templates/gemini-md-rules.md](templates/gemini-md-rules.md): respond in the request's language, use code maps before broad code searches, and search `MEMORY.md` → relevant memory entries → conversation links/tags → conversation text. Preserve native Antigravity workflows and use Olympus only for their documented additional deliverables.

+ If these sources are insufficient, narrow the project and time range and confirm the actual source transcript path and format. `hooks/save-turn.js` exports `latestTurn(payload)` for read-only extraction of the latest user/model pair; it is not a full-history recovery command. Earlier turns require scoped, read-only parsing of user/model text. Never call `appendTurn` or replay the Stop hook for a read-only request, and never load an entire transcript into context or claim an unavailable recovery command succeeded.

Use `--check` after installation. A failed check means the adapter is not verified; do not report Mnemo as active.
