openclaw - 💡(How to fix) Fix MemOS stopped capturing after 4.26 upgrade - fix: hooks.allowConversationAccess [1 comments, 2 participants]

Symptom · 症状

After upgrading to OpenClaw 4.26, memos-local-openclaw-plugin silently stopped indexing new conversations. No errors, no warnings.

升级 OpenClaw 4.26 后，memos-local 插件静默停止收录新对话。无报错、无警告。

Root Cause · 根因

OpenClaw 4.26 added a security policy (see docs/plugins/hooks.md line ~200):

4.26 新增了插件安全策略：

Non-bundled plugins that need llm_input, llm_output, before_agent_finalize, or agent_end must set hooks.allowConversationAccess = true

memos-local relies on agent_end and before_prompt_build hooks for auto-capture and auto-recall. These hooks are silently blocked without explicit allowConversationAccess.

memos-local 依赖 agent_end 和 before_prompt_build hooks 实现自动记忆收录和回忆注入。未声明 allowConversationAccess 时这些 hooks 被静默拦截。

Fix · 修复

openclaw config set plugins.entries.memos-local-openclaw-plugin.hooks.allowConversationAccess true
openclaw gateway restart

Or in openclaw.json:

{
  "plugins": {
    "entries": {
      "memos-local-openclaw-plugin": {
        "hooks": { "allowConversationAccess": true }
      }
    }
  }
}

How we diagnosed · 排查过程

1. memory_search only returned pre-4.26 results → 记忆搜索只返回升级前结果
2. SQLite: last chunk timestamp stopped at upgrade date → 数据库最后 chunk 停在升级日期
3. LM Studio embedding API verified working (2560 dims) → Embedding 模型正常工作
4. Diffed 1.0.9 vs 1.0.10-beta.1 source → identical core, ruled out version bug → 源码相同，排除版本问题
5. Found docs/plugins/hooks.md line ~200 → discovered the requirement → 翻文档找到这条规则
6. Added config + restart → ✅ confirmed working → 加配置+重启，验证通过

Affected · 影响范围

Any non-bundled plugin subscribing to agent_end, before_agent_finalize, llm_input, or llm_output hooks. Same fix applies.

任何依赖对话 hooks 的外部插件同样受影响，修复方法相同。
