+---
+
+Add persistent memory to [**Google Antigravity**](https://antigravity.google) (`agy` CLI and Desktop IDE) with the Mem0 plugin. Your agent forgets everything between sessions — Mem0 fixes that by storing decisions, preferences, and learnings so they carry over automatically.
+
+## Prerequisites
+
+1. A Mem0 API key (starts with `m0-`):
+   - <a href="https://app.mem0.ai/dashboard/api-keys?utm_source=oss&utm_medium=integration-antigravity" rel="nofollow">Get your API key</a> (free sign-up at <a href="https://app.mem0.ai?utm_source=oss&utm_medium=integration-antigravity" rel="nofollow">app.mem0.ai</a>)
+
+2. Add it to your shell profile so it persists across sessions:
+
+<CodeGroup>
+```bash zsh
+echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.zshrc && source ~/.zshrc
+```
+
+```bash bash
+echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.bashrc && source ~/.bashrc
+```
+</CodeGroup>
+
+## Installation
+
+**Option A — degit** (one command, no clone needed):
+
+```bash
+npx degit mem0ai/mem0/mem0-plugin/.antigravity ~/.gemini/config/plugins/mem0
+```
+
+**Option B — agy CLI** (if you have the repo cloned):
+
+```bash
+agy plugin install /path/to/mem0/mem0-plugin/.antigravity
+```
+
+**Option C — MCP only** (no hooks or skills):
+
+Create `~/.gemini/config/plugins/mem0/plugin.json`:
+
+```json
+{
+  "name": "mem0",
+  "mcpServers": {
+    "mem0": {
+      "serverUrl": "https://mcp.mem0.ai/mcp/",
+      "headers": { "Authorization": "Token ${MEM0_API_KEY}" }
+    }
+  }
+}
+```
+
+Restart Antigravity. The full plugin auto-registers the MCP server, lifecycle hooks, scripts, and all `/mem0:` skills. It reads `MEM0_API_KEY` from your environment automatically — no extra config needed.
+
+
+
+## What's Included
+
+| Component | Full Plugin (A/B) | MCP Only (C) |
+|-----------|:-----------------:|:------------:|
+| MCP Server (9 memory tools) | Yes | Yes |
+| Lifecycle Hooks | Yes | No |
+| 16 Slash Commands | Yes | No |
+
+## Available MCP Tools
+
+| Tool | Description |
+|------|-------------|
+| `add_memory` | Save text or conversation history for a user/agent |
+| `search_memories` | Semantic search across memories with filters |
+| `get_memories` | List memories with filters and pagination |
+| `get_memory` | Retrieve a specific memory by ID |
+| `update_memory` | Overwrite a memory's text by ID |
+| `delete_memory` | Delete a single memory by ID |
+| `delete_all_memories` | Bulk delete all memories in scope |
+| `delete_entities` | Delete a user/agent/app/run entity and its memories |
+| `list_entities` | List users/agents/apps/runs stored in Mem0 |
+
+## Lifecycle Hooks
+
+The plugin uses the same shell scripts as Claude Code, Cursor, and Codex — hooks bridge environment variables using `${extensionPath}` (Antigravity's plugin-root token).
+
+| Hook | Event | What it does |
+|------|-------|-------------|
+| **Session start** | `SessionStart` | Loads prior memories and displays status banner |
+| **User prompt** | `UserPromptSubmit` | Searches relevant memories before each message |
+| **Pre-tool** | `PreToolUse` | Blocks MEMORY.md writes, enforces `user_id`/`app_id` on mem0 tools |
+| **Post-tool** | `PostToolUse` | Tracks stats, scans bash errors for related memories |
+
+## Troubleshooting
+
+- **No tools appearing** — Restart your Antigravity session after installation
+- **"Connection failed"** — Verify your key is set: `echo $MEM0_API_KEY`
+- **MCP 401 Unauthorized** — If `${MEM0_API_KEY}` interpolation doesn't work in your `agy` version, replace with your literal key in `mcp_config.json`

 When installed via the plugin marketplace, Mem0 hooks into Claude Code's lifecycle to automatically manage memory:
 
-### Session Start
-On every new session, the plugin prompts Claude to call `search_memories` to load relevant context from prior sessions. On resumed or post-compaction sessions, it adjusts the prompt accordingly.
-
-### User Prompt
-Before processing each user message, the plugin searches Mem0 for memories relevant to the current prompt and injects them into context. Short prompts (< 20 characters) are skipped to minimize latency.
-
-### Pre-Compaction
-Before context compaction, the plugin prompts Claude to store a comprehensive session summary — including goals, accomplishments, decisions, modified files, and current state — so nothing is lost.
-
-### Task Completed
-After each task completion, the plugin prompts Claude to extract and store key learnings: successful strategies, failed approaches, architectural decisions, and new conventions.
-
-### Session End
-When Claude finishes responding, the plugin prompts for any unstored learnings and captures transcript state via the Mem0 REST API as a background safety net.
