# Claude-Supermemory

> Supermemory's official Claude Code plugin: hooks save memories automatically when a session ends and recall them on demand, giving persistent memory across sessions and projects, with shared project memory for teams. Needs a Supermemory API key and Node.js 18+.

A Claude Code plugin that gives your agent persistent memory across sessions using
[Supermemory](https://supermemory.ai). Your agent remembers what you worked on, across
sessions and across projects.

## Installation

> **Requires Node.js 18+** on your PATH. The memory hooks run as Node scripts.

```bash
/plugin marketplace add supermemoryai/claude-supermemory
/plugin install supermemory
```

Set your API key (get one at [console.supermemory.ai](https://console.supermemory.ai)),
or just start a session and let browser login handle it:

```bash
export SUPERMEMORY_CC_API_KEY="sm_..."
```

<details>
<summary>Migrating from the old <code>claude-supermemory</code> plugin</summary>
<br>

That plugin was renamed to `supermemory`, so it won't update in place. Migrate with:

```bash
/plugin marketplace update supermemory-plugins
/plugin install supermemory@supermemory-plugins
```

Then, only if you still have the old plugin installed, remove it:

```bash
/plugin uninstall claude-supermemory@supermemory-plugins
```

## Features

|  |  |
| --- | --- |
| 🧠 **Direct recall**<br>When authenticated, the hook searches substantive prompts before Claude sees them and injects fresh matches. No permission prompt or MCP tool call. | 🔎 **Hosted MCP tools**<br>`search_memory`, `listSpaces`, `whoAmI`, and more are available through the same credentials as the hooks, auto-approved when read-only. |
| 💾 **Auto capture**<br>At the end of a session, the Stop hook saves new conversation content in the background. It asks Supermemory to retain durable context rather than transient Git state. | 🏷️ **Shared repo memory**<br>Automatic captures use the repository container shared with Codex and OpenCode and carry `sm_scope: personal` metadata. |
| 🧭 **Deep multi-container search**<br>The `context-gatherer` subagent fans out several searches across a project's containers and returns a synthesized brief. | ⚙️ **Project config**<br>Per-repo settings, API keys, and container tag overrides via `.claude/.supermemory-claude/config.json`. |
| 🗂️ **Codebase index**<br>`/supermemory:index` saves architecture, conventions, and how to run into this project's container. | 👋 **Session context**<br>Loads profile facts at session start and shows a welcome-back notice when you return to a project after 6+ hours. |

- **Recall strip** — On Claude Code 2.1.287+ in the terminal, press the changing memory headline above the prompt to browse the full returned facts one at a time

On Claude Code 2.1.250, local marketplace install/update and the `SessionStart` and `UserPromptSubmit` command hooks were verified, but `claude plugin validate` rejects the recall mod's `classic.SessionStart` event. The strip is not available on that version; other older versions and install sources have not been verified.

## How it works

Claude Code supports hooks and MCP servers. `supermemory` registers four hooks, in lifecycle order:

**`SessionStart`** → **`UserPromptSubmit`** → **`PreToolUse`** → **`Stop`**

| Step | Hook | Event | What it does |
| --- | --- | --- | --- |
| 1 | `session-start` | `SessionStart` | Bootstraps auth and loads profile context plus a welcome-back notice. It does not install a statusline; an old auto-installed one is removed. |
| 2 | `recall-directive` | `UserPromptSubmit` | Searches Supermemory directly with the prompt and injects fresh matches, deduplicated within the session. |
| 3 | `recall-approve` | `PreToolUse` | Auto-allows read-only Supermemory MCP tools; writes still ask for permission. |
| 4 | `capture` | `Stop` | Saves the completed conversation delta in the background. |

By default, recall is performed by the hook itself, not delegated to the model. It searches
substantive prompts when authenticated, without waiting for Claude to choose a tool call.
Setting `recallDirective` switches to advisory mode: the hook stops searching and instead
tells Claude when it should decide to search on its own.

The hooks are tolerant: if Supermemory is unreachable, the API key is missing, or
anything else fails, they exit cleanly without breaking your Claude Code session.
A capture that fails is reported the next time a session starts.

### Shared Agents memory

Claude Code, Codex, and OpenCode all generate the same container tag for a given
repository, so new memories are shared:

```text
repo_<project-name>__<remote-hash>   default container for capture and MCP memory tools
sm_scope: personal                   metadata on automatic captures
```

The hash is derived from the normalized Git remote, so clones share memory while
same-named repositories do not collide. Repositories without a remote fall back to
a local path identity. Set `SUPERMEMORY_ISOLATE_WORKTREES=true` to use the worktree
path instead of the remote identity.

Unlike Codex, this plugin does not read older per-tool legacy containers
(`codex_user_*`, `opencode_project_*`, and similar); it only ever uses the single
unified tag above, generated fresh or overridden via `repoContainerTag` /
`SUPERMEMORY_REPO_TAG`.

## Configuration

### Environment variables

| Variable | Purpose |
| --- | --- |
| `SUPERMEMORY_CC_API_KEY` | Your Supermemory API key (browser auth is preferred). |
| `SUPERMEMORY_API_URL` | Override the Supermemory API base URL. |
| `SUPERMEMORY_MCP_URL` | Override the hosted MCP endpoint (default `https://mcp.supermemory.ai/mcp`). |
| `SUPERMEMORY_AUTH_URL` | Override the browser-auth base URL. |
| `SUPERMEMORY_REPO_TAG` | Project-container override, used only when project config has no `repoContainerTag`. |
| `SUPERMEMORY_ISOLATE_WORKTREES` | Set to `true` to key the project container on the worktree path instead of the Git remote. |
| `SUPERMEMORY_DEBUG` | Set to `true` to enable debug logging. |

### Global settings (`~/.supermemory-claude/settings.json`)

```json
{
  "maxProfileItems": 5,
  "signalExtraction": true,
  "signalKeywords": ["remember", "architecture", "decision", "bug", "fix"],
  "signalTurnsBefore": 3,
  "includeTools": ["Edit", "Write"]
}
```

| Option | Description |
| --- | --- |
| `maxProfileItems` | Max memories in context (default: 5). |
| `recallDirective` | Set to switch prompt recall from direct hook search to an advisory instruction Claude reasons over. |
| `signalExtraction` | Only capture important turns (default: false). |
| `signalKeywords` | Keywords that trigger capture. |
| `signalTurnsBefore` | Context turns before signal (default: 3). |
| `includeTools` | Tool calls to explicitly capture. |
| `debug` | Enable debug logging (default: false). |

### Project config (`.claude/.supermemory-claude/config.json`)

Per-repo overrides, created manually or via the settings your team shares:

```json
{
  "apiKey": "sm_...",
  "baseUrl": "https://api.supermemory.ai",
  "repoContainerTag": "my-team-project",
  "signalExtraction": true
}
```

| Option | Description |
| --- | --- |
| `apiKey` | Project-specific API key. |
| `baseUrl` | Supermemory API URL. |
| `repoContainerTag` | Override the unified project container tag. Checked before `SUPERMEMORY_REPO_TAG`. |

## Commands

| Command | Description |
| --- | --- |
| `/supermemory:index` | Index this repo's architecture, conventions, and how to run into the project container. |
| `/supermemory:status` | Show authentication status, API and MCP reachability, and the active project container. |

Search does not have its own command. With a key, the prompt hook searches
substantive prompts. For deeper history, use the `context-gatherer` agent or
the MCP tools. `/supermemory:index` saves codebase structure. For a one-off
save, ask Claude to use the `add_memory` MCP tool. Without `containerTag`,
the proxy defaults it to this repository's container; pass a different tag
to select another space. Conversation turns are saved when a session ends.

## Privacy

Automatic capture sends new conversation content to Supermemory, including tool
content when configured. Before saving, an offline filter replaces common
credential-shaped values (provider tokens, credential assignments, private keys,
Bearer tokens, and URL credentials) with explicit `[REDACTED:…]` markers while
keeping surrounding context. It cannot detect every secret. Existing stored
memories and local transcripts are not rewritten; explicit MCP tool calls and
recall queries are not filtered by this capture-only protection.
