 - **Data Isolation**: The `agent_id` is automatically injected into both `/search/memory` and `/add/message` requests. This ensures completely isolated memory and message histories for different agents, even under the same user or session.
 - **Static Override**: You can also force a specific agent ID by setting `"agentId": "your_agent_id"` in the plugin's `config`.
 
+### Per-Agent Memory Toggle
+
+In multi-agent mode, you can use `MEMOS_ALLOWED_AGENTS` to control exactly which agents have memory enabled. Agents not in the allowlist will skip both memory recall and memory capture entirely.
+
+**Environment variable** (in `~/.openclaw/.env`):
+```env
+MEMOS_MULTI_AGENT_MODE=true
+MEMOS_ALLOWED_AGENTS="agent1,agent2"
+```
+
+Separate multiple agent IDs with commas.
+
+**Plugin config** (in `openclaw.json`):
+```json
+{
+  "plugins": {
+    "entries": {
+      "memos-cloud-openclaw-plugin": {
+        "enabled": true,
+        "config": {
+          "multiAgentMode": true,
+          "allowedAgents": ["agent1", "agent2"]
+        }
+      }
+    }
+  }
+}
+```
+
+**Behavior**:
+| Config | Effect |
+|--------|--------|
+| `MEMOS_ALLOWED_AGENTS` unset or empty | All agents have memory enabled |
+| `MEMOS_ALLOWED_AGENTS="agent1,agent2"` | Only `agent1` and `agent2` are enabled; others are skipped |
+| `MEMOS_ALLOWED_AGENTS="agent1"` | Only `agent1` is enabled; all other agents are skipped |
+| `MEMOS_MULTI_AGENT_MODE=false` | Allowlist has no effect; all requests use single-agent mode |
+
+> **Note**: The allowlist only takes effect when `multiAgentMode=true`. When multi-agent mode is off, memory works for all agents and the allowlist is ignored.
+
+### Per-Agent Configuration (agentOverrides)
+
+Beyond simple on/off toggles, you can configure **different memory parameters for each agent** using `agentOverrides`. Each agent can have its own knowledge base, recall limits, relativity threshold, and more.
+
+**Plugin config** (in `openclaw.json`):
+```json
+{
+  "plugins": {
+    "entries": {
+      "memos-cloud-openclaw-plugin": {
+        "enabled": true,
+        "config": {
+          "multiAgentMode": true,
+          "allowedAgents": ["default", "research-agent", "coding-agent"],
+          "knowledgebaseIds": [],
+          "memoryLimitNumber": 6,
+          "relativity": 0.45,
+
+          "agentOverrides": {
+            "research-agent": {
+              "knowledgebaseIds": ["kb-research-papers", "kb-academic"],
+              "memoryLimitNumber": 12,
+              "relativity": 0.3,
+              "includeToolMemory": true,
+              "captureStrategy": "full_session",
+              "queryPrefix": "research context: "
+            },
+            "coding-agent": {
+              "knowledgebaseIds": ["kb-codebase", "kb-api-docs"],
+              "memoryLimitNumber": 9,
+              "relativity": 0.5,
+              "addEnabled": false
+            }
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+**Environment variable** (in `~/.openclaw/.env`):
+You can use `MEMOS_AGENT_OVERRIDES` to configure a JSON string to override global parameters. Note: `.env` configuration has a lower priority than `agentOverrides` in `openclaw.json`.
+```env
+MEMOS_AGENT_OVERRIDES='{"research-agent": {"memoryLimitNumber": 12, "relativity": 0.3}, "coding-agent": {"memoryLimitNumber": 9}}'
+```
+
+**How it works**:
+- Fields in `agentOverrides.<agentId>` override the global defaults for that specific agent.
+- Only the fields you specify are overridden; all other parameters inherit from the global config.
+- If no override exists for an agent, it uses the global config as-is.
+
+**Overridable fields**:
+
+| Field | Description |
+|-------|-------------|
+| `knowledgebaseIds` | Knowledge base IDs for `/search/memory` |
+| `memoryLimitNumber` | Max memory items to recall |
+| `preferenceLimitNumber` | Max preference items to recall |
+| `includePreference` | Enable preference recall |
+| `includeToolMemory` | Enable tool memory recall |
+| `toolMemoryLimitNumber` | Max tool memory items |
+| `relativity` | Relevance threshold (0-1) |
+| `recallEnabled` | Enable/disable recall for this agent |
+| `addEnabled` | Enable/disable memory capture for this agent |
+| `captureStrategy` | `last_turn` or `full_session` |
+| `queryPrefix` | Prefix for search queries |
+| `maxItemChars` | Max chars per memory item in prompt |
+| `maxMessageChars` | Max chars per message when adding |
+| `includeAssistant` | Include assistant messages in capture |
+| `recallGlobal` | Global recall (skip conversation_id) |
+| `recallFilterEnabled` | Enable model-based recall filtering |
+| `recallFilterModel` | Model for recall filtering |
+| `recallFilterBaseUrl` | Base URL for recall filter model |
+| `recallFilterApiKey` | API key for recall filter |
+| `allowKnowledgebaseIds` | Knowledge bases for `/add/message` |
+| `tags` | Tags for `/add/message` |
+| `throttleMs` | Throttle interval |
+
+## Direct Session User ID
+- **Default behavior**: the plugin still uses the configured `userId` (or `MEMOS_USER_ID`) and stays fully backward compatible.
+- **Enable mode**: set `"useDirectSessionUserId": true` in plugin config or `MEMOS_USE_DIRECT_SESSION_USER_ID=true` in env.
+- **What it does**: when enabled, session keys like `agent:main:<provider>:direct:<peer-id>` reuse `<peer-id>` as MemOS `user_id`.
+- **What it does not do**: non-direct session keys such as `agent:main:<provider>:channel:<channel-id>` keep using the configured fallback `userId`.
+- **Request paths affected**: the same resolver is used by both `buildSearchPayload()` and `buildAddMessagePayload()`, so recall and add stay consistent.
+- **Config precedence**: runtime config still follows the same rule as the rest of the plugin - plugin config first, then `.env` files (`~/.openclaw/.env` -> `~/.moltbot/.env` -> `~/.clawdbot/.env`), then process env.
+
+
 ## Notes
 - `conversation_id` defaults to OpenClaw `sessionKey` (unless `conversationId` is provided). **TODO**: consider binding to OpenClaw `sessionId` directly.
 - Optional **prefix/suffix** via env or config; `conversationSuffixMode=counter` increments on `/new` (requires `hooks.internal.enabled`).

+- **默认行为**：仍然使用配置里的 `userId`（或 `MEMOS_USER_ID`），完全兼容旧行为。
+- **开启方式**：在插件 config 中设置 `"useDirectSessionUserId": true`，或在环境变量中设置 `MEMOS_USE_DIRECT_SESSION_USER_ID=true`。
+- **行为说明**：开启后，像 `agent:main:<provider>:direct:<peer-id>` 这样的私聊 sessionKey，会把 `<peer-id>` 当作 MemOS `user_id`。
+- **不会影响的场景**：像 `agent:main:<provider>:channel:<channel-id>` 这类非私聊 sessionKey，仍继续使用配置好的 fallback `userId`。
+- **作用范围**：同一套解析逻辑同时作用于 `buildSearchPayload()` 和 `buildAddMessagePayload()`，保证 recall 与 add 一致。
+- **配置优先级**：仍遵循插件现有规则——插件 config 优先，其次是 `.env` 文件（`~/.openclaw/.env` -> `~/.moltbot/.env` -> `~/.clawdbot/.env`），最后才回退到进程环境变量。
+

 ## 说明
 - 未显式指定 `conversation_id` 时，默认使用 OpenClaw `sessionKey`。**TODO**：后续考虑直接绑定 OpenClaw `sessionId`。
 - 可配置前后缀；`conversationSuffixMode=counter` 时会在 `/new` 递增（需 `hooks.internal.enabled`）。
