## Workflow

### Step 0: Query Expansion (if --expand)
If `--expand` is enabled, generate related terms before searching:

```
Original: "agentic commerce"
    ↓
Expanded (max 5):
  - agentic commerce (original)
  - AI shopping agent
  - conversational commerce
  - e-commerce AI assistant
  - 智能购物
```

Use the prompt in `sources/query-expansion.md` to generate max 4 related terms (5 total).

### Step 1: Parse Input
Extract keyword, sources, limit, days, language from user input.

### Step 2: Parallel Search
**CRITICAL:** Search all sources in parallel using multiple tool calls in a single message.

For each source:
1. Read source instruction from `sources/{source}.md`
2. Execute API call or WebFetch
3. Parse results

### Step 3: Aggregate & Deduplicate
1. Merge all results
2. Deduplicate by URL and title similarity (>80% = duplicate)
3. Sort by: relevance score, date, engagement
4. Tag with source name

### Step 4: Output
Generate `raw/aggregated.md`:

```markdown
# Aggregated Search: {keyword}

**Sources:** {count} sources searched
**Results:** {total} unique items
**Generated:** {timestamp}
