## How Claude Should Use This Skill

**Important for Token Efficiency:**
Deep research takes 10-20 minutes to complete. The skill is designed to run synchronously (blocking) without intermediate status checks. This approach minimizes token usage during the wait. Claude should:
1. Start the research
2. Wait for completion (subprocess blocks automatically)
3. Present final results once complete

No need for periodic polling or status updates during execution.

### Step 1: Accept Research Request

Receive the user's research prompt. This can range from brief ("Latest AI trends") to highly detailed ("Impact of language models on developer productivity with focus on 2024-2025").

### Step 2: Execute the Orchestration Script

Run the skill's main orchestration script with the user's research prompt:

```bash
python3 scripts/run_deep_research.py "Your research prompt here"
```

The script is located at `scripts/run_deep_research.py` within the skill's installation.

### Step 3: Script Execution Flow

The script automatically:

1. **Assesses prompt completeness**: Checks if prompt is too brief or generic (< 15 words or starts with "what is", "how to", etc.)

2. **Asks clarifying questions** (if needed):
   - Presents 2-3 focused questions relevant to the research type
   - Detects if research is technical or general based on keywords
   - Allows users to select from predefined options (1-4) or provide custom text
   - Questions cover: Scope/Timeframe, Depth level, Focus areas

3. **Enhances the prompt**: Combines original prompt with user's answers into structured research parameters

4. **Saves prompt file**: Writes enhanced prompt to `research_prompt_YYYYMMDD_HHMMSS.txt` for reproducibility

5. **Executes deep research**: Runs the core `deep_research.py` script with:
   - Model: o4-mini-deep-research (configurable via `--model`)
   - Timeout: 1800 seconds / 30 minutes (configurable via `--timeout`)
   - Tools: Web search enabled by default

### Step 4: Present Results to User

The script automatically:
- **Saves markdown file**: Research report with sources saved to `research_report_YYYYMMDD_HHMMSS.md`
- **Prints to terminal**: Complete research report with markdown formatting
- **Lists web sources**: Numbered URLs referenced in the research
- **Confirms completion**: Path where research files were saved

**Token Efficiency Note**: Deep research takes 10-20 minutes. The script runs synchronously (blocking) without intermediate polling, minimizing token usage during the wait.

## Bundled Resources

### Scripts

#### `scripts/run_deep_research.py` (Main Entry Point)

The orchestration script that handles:
- Prompt quality assessment

## Key Behaviors

### Smart Prompt Enhancement

The skill intelligently determines whether enhancement is needed:
- **Triggers enhancement** for prompts with < 15 words or generic starts
- **Skips enhancement** for detailed, specific prompts
- **Allows users** to disable with `--no-enhance` flag
- **Template-aware**: Uses different questions for technical vs. general research

### Research Parameters

Enhanced prompts include:
- Original user query with full context
- Scope and timeframe preferences
- Desired depth level (summary, technical, implementation, comparative)
- Specific focus areas (performance, cost, security, etc.)

These parameters help the deep research model deliver more targeted, relevant results.

### Reproducibility

Every research execution:
- Saves the exact prompt used to a timestamped file
- Enables tracing research decisions
- Allows follow-up research using same/modified prompts
- Maintains audit trail of research parameters

## Examples

### Brief Prompt with Enhancement

**User:** "Research the most effective opensource RAG solutions"

**Script behavior:**
1. Detects brief prompt (12 words) + technical keywords ("opensource", "RAG")
2. Asks technical research questions:
   - Technology scope: Open-source only? (User: Yes)
   - Key metrics: Performance/benchmarks? (User: Speed and Accuracy)
   - Use cases: Production deployment? (User: Multiple aspects)
3. Enhances to detailed prompt with parameters
4. Saves and executes deep research
5. Returns comprehensive report with comparative benchmarks and source URLs

### Detailed Prompt Without Enhancement

**User:** "Analyze the impact of large language models on software developer productivity in 2024-2025, focusing on code generation tools, pair programming, and productivity metrics."

**Script behavior:**
1. Detects detailed prompt (24 words) with specific scope/focus
2. Skips enhancement questions
3. Saves and executes deep research immediately
4. Returns focused analysis aligned with user specifications

## Requirements

- Python 3.7+
- OpenAI API key (set via `OPENAI_API_KEY` environment variable or `.env` file)
- Internet connection (for web search)
- 30+ minutes for research completion (configurable timeout)

## Token-Efficient Workflow

### Long-Running Task Optimization

Deep research queries typically take **10-20 minutes** to complete. This skill is optimized to minimize token usage during long waits:

**How it works:**
1. **Synchronous execution**: The script runs as a blocking subprocess (no background polling)
2. **No intermediate checks**: Claude waits silently for completion without status updates
3. **Single output**: Results are presented once at the end
4. **Automatic saving**: Markdown files are saved automatically, no manual intervention needed

**Token savings:**
- Traditional approach: Checking status every 30 seconds = ~40 checks × 500 tokens = ~20,000 tokens wasted
- This approach: Single wait = ~1,000 tokens total

### Automatic File Management

The skill automatically generates and saves files:

**Generated files:**
- `research_prompt_YYYYMMDD_HHMMSS.txt` - Enhanced research prompt with parameters
- `research_report_YYYYMMDD_HHMMSS.md` - Complete markdown report with:
  - Research sections (historical, cognitive, cultural, etc.)
  - Numbered source citations
  - Metadata footer (date, model)

**Customization options:**
```bash
# Custom output location
python3 deep_research.py --prompt-file prompt.txt --output-file my_research.md

# Disable automatic saving (terminal output only)
python3 deep_research.py --prompt-file prompt.txt --no-save
```

## Troubleshooting

### Missing OPENAI_API_KEY

**Error:** "Missing OPENAI_API_KEY"

**Solution:**
- Set environment variable: `export OPENAI_API_KEY="your-key"`
- Or create `.env` file in working directory with `OPENAI_API_KEY=your-key`

### deep_research.py Not Found

**Error:** "Could not find deep_research.py"

**Solution:**
- Ensure skill is properly installed with assets
- Script searches in: skill assets folder → current directory → parent directory

### Research Timeout

**Error:** Request times out after 30 minutes

**Solution:**
- Increase timeout: `--timeout 5400` (90 minutes)
- Simplify prompt to reduce research scope
- Run during off-peak hours for potentially faster API responses
