Quick Start Workflow

快速开始流程

Step 1: Determine Filing Period

步骤1：确定报告周期

If user did NOT specify a period, use WebSearch to find the latest filing:

WebSearch: "{company_name} latest 10-K 10-Q SEC filing"

IMPORTANT: Always analyze the MOST RECENT filing by date, regardless of type (10-K or 10-Q).

Example decision logic:

If latest 10-K is 2024-12-31 and latest 10-Q is 2025-09-30 → Use 10-Q (more recent)
If latest 10-K is 2025-01-15 and latest 10-Q is 2024-09-30 → Use 10-K (more recent)

Inform user: "根据搜索，{TICKER} 最新的财报是 {10-K/10-Q}（截至 {period}），将分析该期财报"

如果用户未指定周期，使用WebSearch查找最新文件：

WebSearch: "{company_name} latest 10-K 10-Q SEC filing"

重要提示：无论报告类型是10-K还是10-Q，始终分析日期最新的文件。

示例决策逻辑：

若最新10-K为2024-12-31，最新10-Q为2025-09-30 → 使用10-Q（更新）
若最新10-K为2025-01-15，最新10-Q为2024-09-30 → 使用10-K（更新）

告知用户："根据搜索，{TICKER} 最新的财报是 {10-K/10-Q}（截至 {period}），将分析该期财报"

Step 2: Download Filing

步骤2：下载文件

bash

python3.11 scripts/download_sec_filings.py --ticker <TICKER> --type <10-K|10-Q|6-K> --limit 1

Output:

<project_root>/investment-research/{TICKER}/tmp/sec_filings/cleaned.txt

bash

python3.11 scripts/download_sec_filings.py --ticker <TICKER> --type <10-K|10-Q|6-K> --limit 1

输出：

<project_root>/investment-research/{TICKER}/tmp/sec_filings/cleaned.txt

Step 3: Dynamic Framework Generation

步骤3：动态生成分析框架

Read first 5000 characters of filing
Identify company industry
Select modules from
```
industry-analysis-modules.md
```
Merge with
```
financial-analysis-framework.md
```
Save to
```
tmp/analysis-framework-YYYY-MM-DD.md
```

读取文件前5000个字符
识别公司所属行业
从
```
industry-analysis-modules.md
```
中选择模块
与
```
financial-analysis-framework.md
```
合并
保存至
```
tmp/analysis-framework-YYYY-MM-DD.md
```

Step 4: Execute Deep Research

步骤4：执行深度研究

Gemini Mode:

bash

python3.11 scripts/gemini_deep_research.py \
  --input <cleaned.txt path> \
  --prompt <analysis framework path> \
  --output-dir <project_root>/investment-research/<TICKER> \
  --ticker <TICKER> \
  --company <Company Name> \
  --phase all

Claude Native Mode: Follow

prompts/claude-deep-research-protocol.md

for complete 7-phase execution.

Gemini模式：

bash

python3.11 scripts/gemini_deep_research.py \
  --input <cleaned.txt path> \
  --prompt <analysis framework path> \
  --output-dir <project_root>/investment-research/<TICKER> \
  --ticker <TICKER> \
  --company <Company Name> \
  --phase all

Claude原生模式： 遵循

prompts/claude-deep-research-protocol.md

完成7阶段执行。

Step 5: Format and Save

步骤5：格式化并保存

Format per

markdown-formatter-rules.md

, save to

investment-research/{TICKER}/

按照

markdown-formatter-rules.md

进行格式化，保存至

investment-research/{TICKER}/

Mode 1: Gemini Deep Research

模式1：Gemini深度研究

User Input → Download Filing → Framework Generation → Phase 1 Filing Analysis → Phase 2 Web Research → Integration → Final Report
                                                              ↓                         ↓
                                                      (Gemini Deep Research)    (Gemini Deep Research)

Phase 1: Upload filing via Files API, Gemini analyzes comprehensively
Phase 2: Web search for competitors, trends, management verification
Integration: Claude merges Phase 1 + Phase 2 per
```
prompts/report-merge-prompt.md
```

用户输入 → 下载文件 → 生成框架 → 阶段1 文件分析 → 阶段2 网络研究 → 整合 → 最终报告
                                                              ↓                         ↓
                                                      (Gemini深度研究)    (Gemini深度研究)

阶段1：通过Files API上传文件，Gemini进行全面分析
阶段2：网络搜索竞争对手、行业趋势、管理层信息验证
整合：Claude按照
```
prompts/report-merge-prompt.md
```
合并阶段1和阶段2的结果

Mode 2: Claude Native Deep Research

模式2：Claude原生深度研究

Uses 7-Phase Deep Research + Graph of Thoughts (GoT) methodology.

For complete execution details, see:

prompts/claude-deep-research-protocol.md
