+2026-03-06 10:00 - 初始化 TradingAgent 因子规则分析师任务
+
+- 用户要求：跑通 OpenCode ACP，然后 fork/clone TradingAgents，并新增因子规则分析师能力。
+- 实际情况：Feishu 不支持 ACP thread binding，按 acp-router 技能回退到 acpx 直连 OpenCode。
+- 已完成：验证 xwang gpt-5.4 可用；本地 clone TradingAgents 到 projects/tradingagent。
+- 下一步：用 acpx 驱动 OpenCode 完成代码实现、验证并提交。
+
+2026-03-06 11:40 - 直接接管 TradingAgents 改造并落地 factor rule analyst
+
+- 新增 `tradingagents/agents/utils/factor_rules.py`：支持从配置/环境变量/默认路径加载 JSON 因子规则，并生成结构化摘要。
+- 新增 `tradingagents/agents/analysts/factor_rule_analyst.py`：基于手动规则生成 analyst 报告。
+- 接入 `agent_states.py`、`propagation.py`、`agents/__init__.py`、`graph/setup.py`、`graph/conditional_logic.py`、`graph/trading_graph.py`，使 factor rule analyst 成为默认 analyst 链的一部分。
+- 修改 bull/bear researcher、research manager、trader、risk manager，使其使用 `factor_rules_report`。
+- 新增 `tradingagents/examples/factor_rules.json` 示例规则文件，并更新 README/main.py/default_config.py。
+- 验证结果：`python -m compileall tradingagents` 通过；`factor_rules.py` 可独立加载并输出摘要。更深的图执行验证受本地缺少 `langchain_core` 依赖限制。
+- 下一步：git commit 当前实现；若需要再补装依赖做端到端运行验证。

 You can also adjust the default configuration to set your own choice of LLMs, debate rounds, etc.
 
+### Factor Rule Analyst
+
+TradingAgents now supports an optional `factor_rules` analyst that loads manually curated factor rules from JSON and injects them into the analyst → researcher → trader workflow.
+
+Default lookup order for factor rules:
+1. `config["factor_rules_path"]`
+2. `TRADINGAGENTS_FACTOR_RULES_PATH`
+3. `tradingagents/examples/factor_rules.json`
+4. `tradingagents/factor_rules.json`
+
+Example rule file format:
+
+```json
+{
+  "rules": [
+    {
+      "name": "AI capex acceleration",
+      "signal": "bullish",
+      "weight": "high",
+      "thesis": "AI infrastructure demand supports growth.",
+      "conditions": ["Backlog rising", "Margins stable"],
+      "rationale": "Use when execution quality remains strong."
+    }
+  ]
+}
+```
+
+Example config:
+
+```python
+config = DEFAULT_CONFIG.copy()
+config["factor_rules_path"] = "./tradingagents/examples/factor_rules.json"
+ta = TradingAgentsGraph(
+    debug=True,
+    config=config,
+    selected_analysts=["market", "social", "news", "fundamentals", "factor_rules"],

+# SPEC - Factor Rule Analyst
+
+## 用户需求
+在 TradingAgents 的分析师体系中新增一个因子规则分析师，支持手动导入固定格式的因子规则，并自动把这些规则作为分析上下文注入给分析师，参与最终分析流程。
+
+## 功能要求
+1. 提供一种明确的因子规则文件格式。
+2. 支持从配置或显式路径加载规则。
+3. 新分析师能读取规则、结合标的与日期输出分析报告。
+4. 报告内容纳入后续研究/交易链路。
+5. 提供示例规则文件与说明文档。
+6. 尽量少改核心架构，优先复用已有 analyst 模式。
+
+## 非目标
+- 不要求实现完整量化回测引擎。
+- 不要求自动学习因子规则。
+- 不要求在线因子数据库。

 4. **Learn from Past Mistakes**: Use lessons from **{past_memory_str}** to address prior misjudgments and improve the decision you are making now to make sure you don't make a wrong BUY/SELL/HOLD call that loses money.
