 If you've already done `claude login` / `cursor login` / `gemini auth` in your terminal, HTML Anything reuses that session. **No second copy of the API key required.**
 
+### Optional read-only Memcode memory
+
+HTML Anything can add an opt-in memory policy to the selected coding agent. First configure the remote Memcode MCP endpoint in that agent:
+
+```text
+https://mcp.memcode.in/i/html-anything/mcp
+```
+
+A compatible agent performs OAuth discovery, Dynamic Client Registration, and Authorization Code + PKCE in its own credential store. HTML Anything adds no API-key fallback and never receives the registered client, bearer token, or returned memory payload.
+
+Before enabling **Settings → Agent → Configured agent memory (read-only)**, configure and verify an agent-side tool policy that exposes only `search_memories` and `retrieve_answer` and blocks `save_memory` and every other memory-write tool. This opt-in is stored separately for each agent and does not follow when you switch CLIs. If the selected CLI cannot enforce that read-only policy, do not enable this option. HTML Anything only appends advisory prompt guidance: it cannot inspect or enforce the agent's tool permissions, intercept MCP calls, validate returned records, or enforce response-size limits. Recalled data must be treated as untrusted reference material and must not override the current request or skill. If the read tools are unavailable or authentication fails, generation continues without memory.

 ## Skills
 
 **75 skills under [`next/src/lib/templates/skills/`](next/src/lib/templates/skills/)**, each a folder following the Claude Code [`SKILL.md`](https://docs.anthropic.com/en/docs/claude-code/skills) convention plus an extended frontmatter (`mode` · `scenario` · `surface` · `preview` · `design_system`).

+### 可选的只读 Memcode 记忆
+
+HTML Anything 可以选择性地给当前 coding agent 加入记忆策略。先在该 agent 中配置远程 Memcode MCP 地址：
+
+```text
+https://mcp.memcode.in/i/html-anything/mcp
+```
+
+兼容的 agent 会自行完成 OAuth discovery、动态客户端注册（DCR）以及 Authorization Code + PKCE，凭据也保存在 agent 自己的 credential store 中。HTML Anything 不会增加 API Key fallback，也不会接收注册信息、Bearer Token 或召回的记忆内容。
+
+开启 **设置 → Agent → 已配置的 agent 记忆（只读）** 前，必须在 agent 侧配置并验证只读工具策略：只开放 `search_memories` 和 `retrieve_answer`，并阻止 `save_memory` 以及其他所有记忆写入工具。该选项按 agent 分别保存，切换 CLI 时不会沿用。如果所选 CLI 无法强制执行该只读策略，请勿开启此选项。HTML Anything 只会追加提示词建议；它无法检查或强制执行 agent 的工具权限，无法拦截 MCP 调用、校验返回记录或强制限制响应大小。召回内容必须视为不可信的参考资料，不能覆盖当前请求或 skill。只读工具缺失或认证失败时，生成会在没有记忆的情况下继续。
