# Scenario Analyzer

## Overview

This skill analyzes medium-to-long-term (18-month) investment scenarios
starting from a news headline. It invokes two specialized agents in sequence
(`scenario-analyst` and `strategy-reviewer`) and integrates multi-angle
analysis with a critical review into a comprehensive report.

## When to Use This Skill

Use this skill when:

- You want to analyze the medium-to-long-term investment impact of a news headline
- You want to construct multiple 18-month scenarios
- You want sector/stock impacts organized into 1st/2nd/3rd-order effects
- You need a comprehensive analysis that includes a second opinion

**Examples:**
```
/scenario-analyzer "Fed raises interest rates by 50bp, signals more hikes ahead"
/scenario-analyzer "China announces new tariffs on US semiconductors"
/scenario-analyzer "OPEC+ agrees to cut oil production by 2 million barrels per day"
```

## Prerequisites

- **API Keys**: None (uses only WebSearch/WebFetch)
- **MCP Servers**: None
- **Dependencies**: The scenario-analyst and strategy-reviewer agents must be available via the Task tool

## Workflow

### Phase 1: Preparation

#### Step 1.1: Headline Parsing

Parse the headline provided by the user.

1. **Headline check**
   - Confirm a headline was passed as an argument
   - If not provided, ask the user for input

2. **Keyword extraction**
   - Key entities (company names, country names, institution names)
   - Numeric data (rates, prices, quantities)
   - Actions (raise, cut, announce, agree, etc.)

#### Step 1.2: Event Type Classification

Classify the headline into one of the following categories:

| Category | Examples |
|----------|----------|
| Monetary Policy | FOMC, ECB, BOJ, rate hike, rate cut, QE/QT |
| Geopolitics | War, sanctions, tariffs, trade friction |
| Regulation & Policy | Environmental regulation, financial regulation, antitrust |
| Technology | AI, EV, renewables, semiconductors |
| Commodities | Crude oil, gold, copper, agricultural products |
| Corporate & M&A | Acquisitions, bankruptcies, earnings, industry restructuring |

#### Step 1.3: Reference Loading

Based on the event type, load the relevant references:

```
Read references/headline_event_patterns.md
Read references/sector_sensitivity_matrix.md
Read references/scenario_playbooks.md
```

**Reference contents:**
- `headline_event_patterns.md`: Historical event patterns and market reactions
- `sector_sensitivity_matrix.md`: Event × sector impact-magnitude matrix
- `scenario_playbooks.md`: Scenario-construction templates and best practices

---

### Phase 2: Agent Invocation

#### Step 2.1: Invoke scenario-analyst

Use the Agent tool to invoke the primary analysis agent.

```
Agent tool:
- subagent_type: "scenario-analyst"
- prompt: |
    Perform an 18-month scenario analysis for the following headline.

    ## Target Headline
    [the input headline]

    ## Event Type
    [classification result]

    ## Reference Information
    [summary of the loaded references]

    ## Analysis Requirements
    1. Use WebSearch to collect related news from the past 2 weeks
    2. Construct 3 scenarios — Base/Bull/Bear (probabilities sum to 100%)
    3. Analyze 1st/2nd/3rd-order impacts by sector
    4. Select 3-5 positive- and 3-5 negative-impact stocks (US market only)
    5. Output everything in English
```

**Expected output:**
- List of related news articles
- Details of the 3 scenarios (Base/Bull/Bear)
- Sector impact analysis (1st/2nd/3rd-order)
- Stock recommendation list

#### Step 2.2: Invoke strategy-reviewer

Using the scenario-analyst's results, invoke the review agent.

```
Agent tool:
- subagent_type: "strategy-reviewer"
- prompt: |
    Review the following scenario analysis.

    ## Target Headline
    [the input headline]

    ## Analysis Result
    [the full scenario-analyst output]

    ## Review Requirements
    Review from the following angles:
    1. Overlooked sectors/stocks
    2. Validity of the scenario probability allocation
    3. Logical consistency of the impact analysis
    4. Detection of optimism/pessimism bias
    5. Proposal of alternative scenarios
    6. Realism of the timeline

    Output constructive and specific feedback in English.
```

**Expected output:**
- Pointing out blind spots
- Opinion on the scenario probabilities
- Pointing out bias
- Proposal of alternative scenarios
- Final recommendations

---

### Phase 3: Integration & Report Generation

#### Step 3.1: Integrate Results

Integrate the output of both agents to produce the final investment judgment.

**Integration points:**
1. Fill in the blind spots raised in the review
2. Adjust the probability allocation (if needed)
3. Make the final judgment accounting for bias
4. Formulate a concrete action plan

#### Step 3.2: Generate Report

Generate the final report in the following format and save it to a file.

**Save location:** `reports/scenario_analysis_<topic>_YYYYMMDD.md`

```markdown
