## Tool Combinations — 10 Patterns

Full CLI examples for each pattern → [pipelines.md](pipelines.md)

### 1. Inspect → Extract → Skill (Standard Path)
**When:** Known page with repeating elements
```
scrape(include: structured_data) → extract(selectors) → create_skill → run_skill (verify)
```

### 2. AI Auto-Discover → Skill (Unknown Structure)
**When:** Unknown page, let LLM figure it out
```
ai_extract(schema: "auto") → create_skill → run_skill (verify)
```

### 3. API-First → Query (Bypass HTML, 10x Faster)
**When:** SPA, trading platforms, hidden JSON APIs
```
discover_apis(wait: 10) → query_api(endpoint) → create_skill (optional)
```

### 4. Login → Session → Extract (Authenticated)
**When:** Content behind login wall
```
interact(login actions, session_id) → scrape/extract(protected page)
```
Alternative: `chrome_profile` param for existing browser cookies.

### 5. Search → Batch → AI Extract (Research Pipeline)
**When:** Research, competitor analysis, bulk collection
```
search(query) → batch_scrape(urls, extraction_schema) → job_status
```

### 6. Map → Batch (Full Site Harvest)
**When:** Site audit, content migration, full backup
```
map(max_urls: 200) → batch_scrape(urls, concurrency: 5)
```

### 7. WebSocket → API Reverse Engineering
**When:** Trading, chat, live dashboards
```
monitor_websocket(duration: 30) → discover_apis → query_api (REST fallback)
```

### 8. Screenshot → Debug → Refine (Visual Feedback)
**When:** Selectors not working
```
screenshot → extract(selectors) → [empty?] → screenshot → refine → extract
```

### 9. Skill Iteration Loop (Feedback)
**When:** ALWAYS — every skill needs validation
```
create_skill → run_skill → [bad?] → extract (manual) → create_skill (overwrite) → run_skill
```

### 10. Snapshot → Interact (Ref Targeting)
**When:** Need precise element targeting without fragile CSS selectors
```
snapshot(url) → analyze ARIA refs → interact(url, actions: [{ref: "N"}]) → snapshot(url) to verify
```

## Smart Scrape

*Use when: "scrape a website", "get content from URL", "read this article", "grab the text", "get product info"*

→ **Full guide: [smart-scrape.md](smart-scrape.md)**

### Quick Decision

| User intent | Tool path |
|-------------|-----------|
| Read article / get text | `readability` → if empty → `scrape` (markdown) |
| Get product info / extract prices | `scrape` (structured_data) → `extract` (CSS) → `llm_fallback` if empty |
| Unknown page structure | `ai_extract` (schema: "auto") |
| General scrape | `scrape` (markdown + metadata + links) |
| Visual capture | `screenshot` (full_page) |

### Stealth Escalation

| Situation | Action |
|-----------|--------|
| Simple static site | Default (auto-escalation handles it) |
| Known anti-bot (Cloudflare, Amazon, LinkedIn) | `stealth_level: 3` directly |
| JavaScript SPA (React, Angular, Vue) | `stealth_level: 3` (needs browser) |
| Empty/blocked results | `stealth_level: 3` + `proxy` |

### Key Tool Chains

- **readability → scrape** escalation
- **extract + llm_fallback**: CSS first, LLM if empty — best of both worlds
- **ai_extract → extract**: AI discovers structure → CSS for fast repeat runs
- **screenshot debug loop**: visual → extract → refine → extract

---

## Build Skill

*Use when: "create a scraper", "build an extractor", "make a skill", "save this pattern", "automate this scraping"*

→ **Full guide: [build-skill.md](build-skill.md)**

### Workflow Summary — 6 Steps

1. **Gather Requirements** — What data? Single/multiple pages? Login needed? Recurring?
2. **Page Inspection** — `scrape` with `include: [structured_data, links, metadata]`
3. **Pattern Detection** — CSS (`extract`) vs AI (`ai_extract`) vs Hybrid (`llm_fallback`)
4. **Create Skill** — `create_skill` with `url`, `name`, `description`
5. **Verify — MANDATORY** — `run_skill` on original + different page
6. **Educate User** — How to run, override URL, limit items, storage location

### Common Selectors

| Site Type | items_selector | Typical Fields |
|-----------|---------------|----------------|
| E-commerce | `.product-card`, `.item`, `[data-product]` | name, price, image, url, rating |
| News/Blog | `article`, `.post`, `.story` | title, date, author, excerpt, url |
| Job Board | `.job-listing`, `.vacancy` | title, company, location, salary, url |
| Directory | `.listing`, `.result` | name, address, phone, website, category |
| Table Data | `table tbody tr` | cell values by `td:nth-child(N)` |

### Built-in Recipes

Check before building custom skills → [recipes.md](recipes.md):
`hn-top-stories`, `github-trending`, `job-listings-greenhouse`, `ecommerce-product`, `product-reviews`, `crypto-websocket`, `news-article-reader`, `reddit-posts`, `seo-page-audit`, `social-media-mentions`

Run: `run_skill(name: "recipe-name")` / `imperium-crawl run-skill --name "recipe-name"`

---

## Site Intel

*Use when: "analyze this website", "map this site", "site audit", "what is this website about"*

→ **Full guide: [site-intel.md](site-intel.md)**

### Workflow Summary

1. **Site Mapping** — `map(url, max_urls: 100, include_sitemap: true)` → group URLs by section
2. **Homepage Deep-Dive** — `scrape(url, include: [structured_data, metadata, links])` → identity, tech stack
3. **Content Crawl** — `crawl(url, max_depth: 2, max_pages: 10)` → content types, quality
4. **Visual Capture** — `screenshot(url)` → design, layout
5. **Compile Report** — Overview, Structure, Content, Technology, Scraping Recommendations

### Depth Guidelines

| Request | map max_urls | crawl max_pages |
|---------|-------------|-----------------|
| Quick overview | 50 | 5 |
| Standard analysis | 100 | 10 |
| Deep audit | 200-500 | 20-30 |

### Bonus Steps

- **Batch harvest**: `map` → `batch_scrape(urls, concurrency: 5)` → full site data
- **API discovery**: `discover_apis(url, wait_seconds: 10)` → find hidden JSON endpoints
- **SEO extract**: `extract(url, selectors: {title, h1, meta_desc})` per page

---

## Research

*Use when: "research a topic", "find information about X", "deep dive into Z", "gather intel"*

→ **Full guide: [research.md](research.md)**

### Workflow Summary

1. **Decompose** — Core question, angles, recency needs, depth
2. **Formulate queries** — 2-3 targeted queries (primary, comparative, expert)
3. **Search** — `search(query, count: 10)` + optionally `news_search(query, freshness: "pw")`
4. **Select sources** — 3-5 URLs: authoritative, content-rich, diverse, recent
5. **Deep scrape** — `readability` first → fallback `scrape`. Or `batch_scrape` for 5+ sources
6. **Synthesize report** — Key Findings, Detailed Analysis, Sources with summaries

### Freshness Values

`pd` (past day), `pw` (past week), `pm` (past month), `py` (past year). Requires `BRAVE_API_KEY`.

### Depth Guidelines

| Request | Sources | Approach |
|---------|---------|----------|
| Quick | 1-2 | Single search, top results |
| Standard | 3-5 | 2 searches, curated |
| Deep dive | 5-8 | 3 searches + news |
| Competitive | 4-6 per competitor | Targeted per entity |

---

## API Recon

*Use when: "find APIs on a website", "discover hidden endpoints", "reverse engineer an API", "monitor WebSocket"*

→ **Full guide: [api-recon.md](api-recon.md)**

### Workflow Summary

1. **Discovery** — `discover_apis(url, wait_seconds: 8, include_headers: true)`
2. **Categorize** — By type (REST/GraphQL/WS), origin (1st/3rd party), auth (none/cookie/bearer/key/CSRF)
3. **Investigate** — `query_api` for GET endpoints, GraphQL introspection, pagination testing
4. **WebSocket** — `monitor_websocket(url, duration: 15-60)` → message format, types, auth
5. **Report** — Summary, API Inventory table, Detailed Analysis, Recommendations

### wait_seconds Tuning

| Site type | wait_seconds |
|-----------|-------------|
| Simple static | 5 |
| Standard web app | 8 |
| Heavy SPA | 12-15 |
| Infinite scroll | 15-20 |

### Key Tool Chains

- **discover → query → monitor** — full recon chain
- **interact (login) → discover** — authenticated API recon
- **websocket → query_api** — REST fallback (easier to automate)

---

## CLI Gotchas

**Boolean flags** — no value needed:
```bash
imperium-crawl screenshot --url URL --full-page     # correct
imperium-crawl screenshot --url URL --full-page true # wrong
```

**JSON params** — single quotes around JSON:
```bash
imperium-crawl extract --url URL --selectors '{"title":"h1","price":".cost"}'
```

**Output formats:**
```bash
--output-format json|csv|jsonl|markdown
--pretty          # human-readable JSON
--output file.json # write to file
```

**Pipe-safe:** Spinner → stderr, data → stdout:
```bash
imperium-crawl scrape --url URL --output-format json | jq '.title'
```

**Include:** `--include structured_data,links,metadata` (comma-separated, no spaces)

**Actions JSON:**
```bash
imperium-crawl interact --url URL --actions '[{"type":"click","selector":"button"},{"type":"wait","duration":2000}]'
```

**Batch URLs:** `--urls "url1,url2,url3"` (comma-separated in quotes)

**Freshness:** `--freshness pd` (pd=day, pw=week, pm=month, py=year)

## Error Recovery

| Error | Cause | Fix |
|-------|-------|-----|
| Empty content | JS-rendered or blocked | `stealth_level: 3` or `llm_fallback: true` |
| 403/Blocked | Anti-bot protection | `stealth_level: 3` + `proxy` |
| Timeout | Slow page / heavy JS | Increase `timeout`; try `readability` |
| Readability garbage | Non-article page | Fallback to `scrape` (markdown) |
| CAPTCHA | Bot detection | Auto-solved if `TWOCAPTCHA_API_KEY` set + Level 3 |
| Login required | Protected content | `interact` with session_id, or `chrome_profile` |
| Skill works, run_skill fails | Selectors changed | Re-inspect, recreate skill |
| `LLM_API_KEY` missing | ai_extract needs it | Run `imperium-crawl setup` |
| `BRAVE_API_KEY` missing | Search tools need it | Run `imperium-crawl setup` |
| CLI JSON parse error | Bad JSON | Validate JSON, single quotes, escape inner quotes |
| Batch job stalled | Network issues | Resume with same `job_id` (completed URLs skipped) |
| No APIs captured | Site needs interaction | Increase `wait_seconds` to 15-20 |
| All third-party APIs | Server-side rendering | Try HTML scraping instead |
| WebSocket refused | Needs auth cookies | `interact` login first, or `chrome_profile` |
