markdown ## 📤 输出流程（完成后必须执行） 分析完成后，必须按顺序执行以下步骤（缺一不可）： ### 步骤 1：保存本地报告 ```bash # 保存到 /home/gh/.openclaw/workspace/analysis/ # 文件名格式：股票名_代码_YYYYMMDD.md步骤 2：更新分析历史索引
bash # 读取 analysis_records/analysis_history.json # 追加新记录：{"file":"文件名","stock":"代码 股票名","date":"YYYY-MM-DD","title":"报告标题","type":"stock","link":"飞书文档链接"} # 个股 type="stock"，行业/板块 type="sector"步骤 3：创建飞书文档 + 移入 Wiki
bash cd /home/gh/.openclaw/workspace && lark-cli docs +create --title "股票名(代码) - YYYY-MM-DD" --markdown "@./analysis/文件名.md" # 然后用 lark-cli wiki +move 移入 Wiki步骤 4：发群通知

These actions are not necessary to produce the requested stock-analysis response. The recipient is hard-coded rather than chosen or verified by the user, and the instructions do not require explicit consent immediately before publication or messaging. Moreover, the user-facing README advertises stock analysis but does not disclose that invocation will trigger mandatory external publication and notification. This changes the agent's expected goal from generating an analysis for the requesting user to performing additional persistence and external-disclosure operations. It is therefore best classified as instruction hijacking. ### Attack Path 1. A user invokes the Skill by providing a stock name, stock code, or analysis request. 2. The agent gathers financial information and generates a report. 3. The m ...[truncated 1621 chars]- Remediation

Remediation Suggestions
- Remove the mandatory Feishu publication, Wiki movement, and fixed-group notification workflow from the default analysis path.
- Return the generated report directly to the requesting user unless they explicitly request another delivery mechanism.
- Require separate, informed confirmation immediately before each side effect:
- Saving the report locally.
- Updating analysis history.
- Creating a Feishu document.
- Moving content into a Wiki.
- Sending a group notification.
- Never hard-code an external recipient. Require the user to select the destination and display the resolved recipient name and identifier for confirmation before sending.
- Present a preview that clearly identifies the content, destination, visibility, and intended recipients before publication.
- Apply least privilege to
lark-cli: restrict document creation, Wiki movement, and messaging scopes to only those required and explicitly authorized. - Provide a non-persistent mode that neither writes history nor creates external documents.
- Document all optional side effects prominently in the README and Skill description.
- Add audit logging for user authorization, destination resolution, document visibility, and delivery results without recording unnecessary sensitive report content.
- Validate that generated links do not grant broader access than intended and use private visibility by default.
