Adds first-class integration with Google's Antigravity IDE (https://antigravity.google/) as a third sibling to the existing Claude Code and Codex hook integrations. Strictly additive — no existing files in main are restructured. What ships ---------- * `.antigravity-plugin/` — verified-minimal plugin package: * `plugin.json` with `{"name": "mempalace"}` (no fabricated fields) * `mcp_config.json` registering the `mempalace-mcp` stdio server * `hooks.json.tmpl` templated with `__PLUGIN_DIR__` substitution * `skills/mempalace/SKILL.md` (real file — no symlinks) * `hooks/antigravity/`: * `lib/common.sh` — shared bash 3.2.57-compatible helpers with sentinel-guarded camelCase JSON parser, antigravity_*-namespaced state files, every existing kill switch, `MEMPAL_SAVE_INTERVAL >= 1` floor (no /0), and fail-open emitters * `mempal_save_hook_antigravity.sh` — Stop event handler: increments per-conversation counter, defers when fullyIdle=False or terminationReason=error, validates transcriptPath against `..` traversal, spawns `mempalace mine --mode convos` in a detached subprocess with a per-conversation pending marker, ALWAYS emits `{}` (never `{"decision":"continue"}` — that would force an infinite agent loop) * `mempal_wake_hook_antigravity.sh` — PreInvocation handler gated to invocationNum==1 with an atomic mkdir loop guard, runs `mempalace wake-up` with a 500ms hard timeout, emits verbatim output as `{"injectSteps":[{"ephemeralMessage":"..."}]}` or `{}` on any failure * `install.sh` — idempotent installer with cmp-gated copies, `__PLUGIN_DIR__` substitution, relative path absolutization, `--dry-run`, and basename-guarded `--uninstall` (refuses to wipe a directory whose basename isn't `mempalace`) * `INVESTIGATION.md` — verbatim quotes + URLs + dates from the five official Antigravity doc pages, recording every surface shipped and every surface deliberately omitted (PreCompact equivalent, slash-commands, rules/, plugin permissions field — the latter is third-party fabrication) * `STDIN_SHAPE.md` — exact stdin/stdout contract per event with worked examples * `README.md` — local hook docs + troubleshooting * `examples/antigravity/{hooks.json,mcp_config.json,README.md}` — standalone configs for users who don't want the full installer * `website/guide/antigravity.md` + sidebar entry — VitePress guide * Updates to `README.md`, `CHANGELOG.md` (Unreleased), `hooks/README.md` Tests (56 new, all passing) --------------------------- * `tests/test_antigravity_plugin_manifest.py` (11 tests) — schema contract on the in-repo `.antigravity-plugin/` directory, including guards against re-introducing the fabricated `permissions` field and against any symlink leak. * `tests/test_antigravity_hooks_shell.py` (31 tests) — invokes the bash hooks via subprocess with synthetic camelCase stdin, asserts `{}` on every failure path, kill-switch coverage (env vars + config.json + palace nuke), divide-by-zero floor, transcript traversal rejection, namespacing, wing inference, and the hard refusal to ever emit `decision=continue` from the Stop hook. * `tests/test_antigravity_hooks_install.py` (14 tests) — `--dry-run` side-effect-free, real install layout, executable bits preserved, byte-identical idempotent re-runs (md5 + filecmp), basename-match uninstall safety, refusal when plugin.json is missing or names a different plugin, relative path absolutization. Skipped on Windows. Verification ------------ * `uv run pytest tests/ --ignore=tests/benchmarks -v` → 2314 passed, 3 skipped (Windows), 1 unrelated warning * `uv run ruff check .` → all checks passed * `uv run ruff format --check .` → 139 files already formatted * `bash -n` clean on common.sh, both hook scripts, install.sh * Local install at `~/.gemini/config/plugins/mempalace/` verified end- to-end: layout correct, paths absolutized in hooks.json, both hooks fire with realistic camelCase JSON in <1s, wing inference picks `wing_mempalace` from workspacePaths[0], state files all `antigravity_*`-namespaced, second `install.sh` run produces byte-identical output (md5 snapshots match), uninstall removes only the mempalace plugin and leaves all 6 sibling Google plugins untouched. Constraints honoured -------------------- bash 3.2.57 (no mapfile / readarray / declare -A / `${var^^}`), verbatim guarantee on all wake injections, hooks <500ms / startup injection <100ms target (kill-switch path returns in <1.5s in CI), zero new runtime dependencies, no telemetry, no external API, strictly additive (existing Claude/Codex hooks unchanged).
