+Set up multi-agent collaboration framework for projects where multiple AI agents work together.
+
+## Triggers
+- "set up multi-agent", "agent guardrails", "multi-agent collaboration"
+
+## Quick Setup (Recommended)
+
+Rapid deployment with minimal questions:
+
+1. Assess project structure
+2. Ask which agents participate (Claude/Gemini/Codex/Human)
+3. Create framework files
+4. Customize ownership matrix
+
+## Files Created

+[Claude] feat(core): implement new feature
+[Gemini] docs(api): update API documentation
+[Codex] test(models): add unit tests
+```
+
+## Post-Setup

+## Input Modes
+
+| Mode | Input Example | Pipeline Start |
+|------|---------------|----------------|
+| **Topic** | `"Claude system prompts"` | reference-discovery |
+| **URLs** | `https://docs.anthropic.com/...` | web-crawler (skip discovery) |
+| **Manifest** | `./manifest.json` | web-crawler (resume) |
+
+## Arguments
+
+- `<input>`: Required. Topic string, URL(s), or manifest file path
+- `--depth`: Crawl depth level (default: `standard`). See Depth Levels below
+- `--output`: Output directory path (default: `~/Documents/reference-library/`)
+- `--max-sources`: Max sources to discover (default: 100)
+- `--max-pages`: Max pages per source to crawl (default varies by depth)
+- `--auto-approve`: Auto-approve scores above threshold
+- `--threshold`: Approval threshold (default: 0.85)
+- `--max-iterations`: Max QA loop iterations per document (default: 3)
+- `--export-format`: `project_files`, `fine_tuning`, `jsonl` (default: project_files)
+- `--include-subdomains`: Include subdomains in site mapping (default: false)
+- `--follow-external`: Follow external links found in content (default: false)
+
+## Output Directory
+
+**IMPORTANT: Never store output in any claude-skills, `.claude/`, or skill-related directory.**
+
+The `--output` argument sets the base path for all pipeline output. If omitted, the default is `~/Documents/reference-library/`.
+
+### Directory Structure
+
+```
+{output}/
+├── {topic-slug}/                   # One folder per pipeline run
+│   ├── README.md                   # Index with table of contents
+│   ├── 00-page-name.md             # Individual page files
+│   ├── 01-page-name.md
+│   ├── ...
+│   ├── {topic-slug}-complete.md    # Combined bundle (all pages)
+│   └── manifest.json               # Crawl metadata
+├── pipeline_state/                 # Resume state (auto-managed)
+│   └── run_XXX/state.json
+└── exports/                        # Fine-tuning / JSONL exports
+```
+
+### Resolution Rules
+
+1. If `--output` is provided, use that path exactly
+2. If not provided, use `~/Documents/reference-library/`
+3. **Before writing any files**, check if the output directory exists
+4. If the directory does NOT exist, **ask the user for permission** before creating it:
+   - Show the full resolved path that will be created

+5. quality-reviewer              |
+   +-- APPROVE -> export         |
+   +-- REFACTOR -----------------+
+   +-- DEEP_RESEARCH -> crawler -+
+   +-- REJECT -> archive
+6. markdown-exporter
+```
+
+## Crawl Execution by Depth
+
+When executing the crawl (Stage 2), apply the depth settings to the Firecrawl tools:
+
+### Site Mapping (`firecrawl_map`)
+```
+firecrawl_map:
+  url: <target>
+  limit: {depth.map_limit}
+  includeSubdomains: {depth.includeSubdomains}
+```
+
+### Page Scraping (`firecrawl_scrape`)
+```
+firecrawl_scrape:
+  url: <page>
+  formats: {depth.formats}
+  onlyMainContent: {depth.onlyMainContent}
+  waitFor: {depth.waitFor}           # deep/full only
+  excludeTags: ["nav", "footer"]     # light/standard only
+```
+
+### Batch Crawling (`firecrawl_crawl`) - for deep/full only
+```
+firecrawl_crawl:
+  url: <target>
+  maxDiscoveryDepth: {depth.maxDiscoveryDepth}
+  limit: {depth.max_pages}
+  deduplicateSimilarURLs: {depth.dedup}
+  scrapeOptions:
+    formats: {depth.formats}
+    onlyMainContent: {depth.onlyMainContent}
+    waitFor: {depth.waitFor}
+```
+
+## Example Usage
+
+```bash
+# Quick scan of a single doc page
+/reference-curator https://docs.example.com/api --depth light
+
+# Standard documentation crawl (default)
+/reference-curator "Glossary for WordPress" --max-sources 5

+   - WebFetch the homepage and parse JSON-LD `<script type="application/ld+json">` tags
+   - Extract from `Organization`, `Hospital`, or `LocalBusiness` schema: Korean name, English name, address, telephone
+   - Check `sameAs` array for GBP, Naver Place, Kakao Map URLs
+
+2. **Check website for listing links**
+   - Scrape footer, contact page, about page for links matching:
+     - GBP: `maps.app.goo.gl/*`, `google.com/maps/place/*`, `g.page/*`
+     - Naver Place: `naver.me/*`, `map.naver.com/*/place/*`, `m.place.naver.com/*`
+     - Kakao Map: `place.map.kakao.com/*`, `kko.to/*`
+   - Check embedded iframes for Google Maps Place IDs or Naver Map embeds
+
+3. **Layered search fallback (if links not found on website)**
+   - GBP: Search `"[Korean Name]" "[district]" Google Maps`, then `"[phone]" site:google.com/maps`
+   - Naver: Search `"[Korean Name]" site:map.naver.com`, then `"[Korean Name]" 네이버 지도 [district]`
+   - Kakao: Search `"[Korean Name]" site:place.map.kakao.com`
+
+4. **Follow `18-seo-local-audit/code/CLAUDE.md` workflow** for the full audit (Steps 2-7)
+
+5. **Important language**: Distinguish **"not discoverable via web search"** from **"does not exist."** GBP and Naver Map are JS-rendered; WebFetch cannot extract their listing data. Absence in search results does not confirm absence of the listing.
+
+6. **Korean market priorities**: GBP and Naver Smart Place are both Critical. Kakao Map is High. US-centric directories (Yelp, Yellow Pages) are Low priority for Korean businesses.

 ## Overview
 
-Local SEO auditor for businesses with physical locations: NAP consistency, Google Business Profile optimization, local citations, and LocalBusiness schema validation.
+Local SEO auditor for Korean-market businesses with physical locations. Covers business identity extraction, GBP optimization, Naver Smart Place, Kakao Map, NAP consistency, local citations, and LocalBusiness schema validation.
-
-## Quick Start
-
-This skill primarily uses MCP tools (Firecrawl, Perplexity) for data collection. Scripts are helpers for validation.
-
-```bash
-# NAP consistency check (manual data input)
-python scripts/nap_checker.py --business "Business Name" --address "123 Main St" --phone "555-1234"
-
-# LocalBusiness schema validation
-python scripts/local_schema_validator.py --url https://example.com
-```
-
-## Audit Components
-
-### 1. NAP Consistency
-**Name, Address, Phone** consistency across:
-- Website (header, footer, contact page)
-- Google Business Profile
-- Local directories (Yelp, Yellow Pages, etc.)
-- Social media profiles
-
-### 2. Google Business Profile (GBP)
-Optimization checklist:
-- [ ] Business name matches website
-- [ ] Address is complete and accurate
-- [ ] Phone number is local
-- [ ] Business hours are current
-- [ ] Categories are appropriate
-- [ ] Photos uploaded (exterior, interior, products)
-- [ ] Posts are recent (within 7 days)
-- [ ] Reviews are responded to
-
-### 3. Local Citations
-Priority directories to check:
-- Google Business Profile
-- Apple Maps
-- Bing Places
-- Yelp
-- Facebook Business
-- Industry-specific directories
-
-### 4. LocalBusiness Schema
-Required properties:
-- @type (LocalBusiness or subtype)
-- name
-- address (PostalAddress)
-- telephone
-- openingHours
 
 ## Workflow
 
+### Step 0: Business Identity (MANDATORY FIRST STEP)
+
+Before any audit work, establish the official business identity.
+
+**Sources (in priority order):**
+1. Website schema markup (JSON-LD `Organization`, `Hospital`, `LocalBusiness`) — the `name` field is authoritative
+2. Contact page / About page
+3. Footer (address, phone, social links)
+4. User-provided information (known GBP URL, Naver Place URL, etc.)
+
+**Data to collect:**
+
+| Field | Example |
+|-------|---------|
+| Official name (Korean) | 제이미성형외과의원 |
+| Official name (English) | Jamie Plastic Surgery Clinic |
+| Brand/display name | Jamie Clinic |
+| Website URL | https://www.jamie.clinic |
+| Address (Korean) | 서울특별시 강남구 ... |
+| Phone | 02-XXX-XXXX |
+| Known GBP URL | (if available) |
+| Known Naver Place URL | (if available) |
+| Known Kakao Map URL | (if available) |
+
+**How to extract:**
 ```
-1. Collect NAP from client
+WebFetch homepage → parse JSON-LD script tags → extract name, address, telephone, sameAs
-2. Scrape website for NAP mentions
+WebFetch /contact or /about → extract NAP from page content
-3. Search citations using Perplexity
+Check footer for social links, map embeds, place listing URLs
-4. Check GBP data (manual or API)
-5. Validate LocalBusiness schema
-6. Generate consistency report
 ```
 
+Look specifically for these URL patterns in `sameAs`, footer links, or embedded iframes:
+- GBP: `maps.app.goo.gl/*`, `google.com/maps/place/*`, `g.page/*`
+- Naver Place: `naver.me/*`, `map.naver.com/*/place/*`, `m.place.naver.com/*`
+- Kakao Map: `place.map.kakao.com/*`, `kko.to/*`
+
+### Step 1: Website NAP Extraction
+
+Scrape header, footer, contact page, about page for NAP mentions. Cross-reference with schema markup. Establish the **canonical NAP** baseline (the single source of truth for this audit).
+
+### Step 2: GBP Verification & Audit
+
+**Layered discovery (try in order, stop when found):**
+1. Use provided GBP URL (from Step 0 or user input)
+2. Check website for GBP link (footer, contact page, schema `sameAs`, embedded Google Maps iframe with Place ID)
+3. WebSearch: `"[Korean Name]" "[City/District]" Google Maps`
+4. WebSearch: `"[English Name]" Google Maps [City]`
+5. WebSearch: `"[exact phone number]" site:google.com/maps`
+
+**Important**: Google Maps is JS-rendered — WebFetch cannot extract business data from the listing page itself. Use WebSearch to find the listing URL, then verify details via search result snippets.
+
+**If found — audit checklist (score /10):**
+- [ ] Business name matches canonical NAP
+- [ ] Address is complete and accurate
+- [ ] Phone number matches
+- [ ] Business hours are current
+- [ ] Primary + secondary categories are appropriate
+- [ ] Business description is complete
+- [ ] 10+ photos uploaded (exterior, interior, products/services)
+- [ ] Posts are recent (within 7 days)
+- [ ] Reviews are responded to
+- [ ] Q&A section is active
+
+**If NOT found after all attempts:** Report as **"not discoverable via web search"** — this is distinct from "does not exist." The listing may exist but be unfindable through non-JS search methods.
+
+### Step 3: Naver Smart Place Verification & Audit
+
+**Layered discovery (try in order, stop when found):**
+1. Use provided Naver Place URL (from Step 0 or user input)
+2. Check website for Naver Place link (footer, contact page, schema `sameAs`, `naver.me/*` or `map.naver.com/*/place/*` patterns)
+3. WebSearch: `"[Korean Name]" site:map.naver.com`
+4. WebSearch: `"[Korean Name]" 네이버 지도 [district]`
+5. WebSearch: `"[Korean Name]" 네이버 스마트플레이스`
+6. WebSearch: `"[exact phone number]" site:map.naver.com`
+
+**Important**: Naver Map is JS-rendered — WebFetch cannot extract data from the listing page. Use WebSearch for discovery, verify via search result snippets.
+
+**If found — audit checklist (score /10):**
+- [ ] Business name matches canonical NAP
+- [ ] Address is complete and accurate
+- [ ] Phone number matches
+- [ ] Business hours are current
+- [ ] Place is "claimed" (owner-managed / 업주 등록)
+- [ ] Keywords/tags are set
+- [ ] Booking/reservation link present
+- [ ] Recent blog reviews linked
+- [ ] Photos uploaded and current
+- [ ] Menu/service/price information present
+
+**If NOT found after all attempts:** Report as **"not discoverable via web search"** (not "does not exist" or "not registered").
+
+### Step 4: Kakao Map Verification
+
+**Discovery:**
+1. Use provided Kakao Map URL (from Step 0)
+2. Check website for Kakao Map link (`place.map.kakao.com/*`, `kko.to/*`)
+3. WebSearch: `"[Korean Name]" site:place.map.kakao.com`
+4. WebSearch: `"[Korean Name]" 카카오맵 [district]`
+
+**If found:** Verify NAP consistency against canonical NAP.
+
+### Step 5: Citation Discovery
+
+**Korean market platform priorities:**
+
+| Platform | Priority | Market |
+|----------|----------|--------|
+| Google Business Profile | Critical | Global |
+| Naver Smart Place (네이버 스마트플레이스) | Critical | Korea |
+| Kakao Map (카카오맵) | High | Korea |
+| Industry-specific directories | High | Varies |
+| Apple Maps | Medium | Global |
+| Bing Places | Low | Global |
+
+**Korean medical/cosmetic industry directories:**
+- 강남언니 (Gangnam Unni)
+- 바비톡 (Babitalk)
+- 성예사 (Sungyesa)
+- 굿닥 (Goodoc)
+- 똑닥 (Ddocdoc)
+- 모두닥 (Modoodoc)
+- 하이닥 (HiDoc)
+
+**Discovery methods:**
+- Phone number search across platforms
+- Korean business name + district search
+- English business name search
+- Address search
+
+### Step 6: NAP Consistency Report
+
+Cross-reference all discovered sources against the canonical NAP from Step 1.
+
+**Common inconsistency points to check:**
+- Building/landmark names (e.g., "EHL빌딩" vs "엔와이빌딩") — the authoritative source is the **business registration certificate** (사업자등록증), not the website alone
+- Phone format variations (02-XXX-XXXX vs +82-2-XXX-XXXX vs 02XXXXXXX)
+- Address format (road-name vs lot-number / 도로명 vs 지번)
+- Korean vs English name spelling variations
+- Suite/floor number omissions
+
+### Step 7: LocalBusiness Schema Validation
+
+Validate JSON-LD completeness:
+- @type (LocalBusiness, Hospital, or appropriate subtype)
+- name (Korean and/or English)
+- address (PostalAddress with Korean format)
+- telephone
+- openingHours / openingHoursSpecification
+- geo (GeoCoordinates — latitude, longitude)
+- sameAs (should include GBP, Naver Place, Kakao Map, social profiles)
+- url
+- image
+
+Use schema generator skill (17) for creating/fixing markup.

 ## Notes
 
-- GBP API requires enterprise approval (use manual audit)
+- GBP and Naver Map are JS-rendered — WebFetch cannot extract listing data directly. Always use WebSearch for discovery.
-- Citation discovery limited to public data
+- "Not discoverable via web search" != "does not exist." Always use this precise language.
-- Use schema generator skill (14) for creating LocalBusiness markup
+- For Korean businesses, Naver Smart Place is as important as GBP (often more so for domestic traffic).
+- Citation discovery is limited to publicly searchable data.

-### 1. Gather Business Info
+### Step 0: Business Identity (MANDATORY FIRST STEP)
-Collect from client:
-- Business name (exact)
-- Full address
-- Phone number (local preferred)
-- Website URL
-- GBP listing URL
 
-### 2. Website NAP Check
+Before any audit, establish the official business identity.
-Scrape website for NAP mentions:
-- Header/footer
-- Contact page
-- About page
-- Schema markup
 
-### 3. Citation Discovery
+**Sources (in priority order):**
-Search for business mentions:
+1. Website schema markup (JSON-LD `Organization`, `Hospital`, `LocalBusiness`) — `name` field is authoritative
-- "[Business Name] [City]"
+2. Contact page / About page
-- Phone number search
+3. Footer (address, phone, social links)
-- Address search
+4. User-provided information
 
-### 4. GBP Review
+**Data to collect:**
-Manual checklist:
-- Profile completeness
-- Category accuracy
-- Photo presence
-- Review responses
-- Post recency
 
-### 5. Schema Check
+| Field | Example |
-Validate LocalBusiness markup presence and accuracy.
+|-------|---------|
+| Official name (Korean) | 제이미성형외과의원 |
+| Official name (English) | Jamie Plastic Surgery Clinic |
+| Brand/display name | Jamie Clinic |
+| Website URL | https://www.jamie.clinic |
+| Address (Korean) | 서울특별시 강남구 ... |
+| Phone | 02-XXX-XXXX |
+| Known GBP URL | (if available) |
+| Known Naver Place URL | (if available) |
+| Known Kakao Map URL | (if available) |
 
-## GBP Optimization Checklist
+Look for these URL patterns in `sameAs`, footer links, or embedded iframes:
+- GBP: `maps.app.goo.gl/*`, `google.com/maps/place/*`, `g.page/*`
+- Naver Place: `naver.me/*`, `map.naver.com/*/place/*`, `m.place.naver.com/*`

-- [ ] Business name matches website
+### Step 1: Website NAP Extraction
-- [ ] Complete address with suite/unit
+
-- [ ] Local phone number (not toll-free)
+Scrape header, footer, contact page, about page. Cross-reference with schema markup. Establish the **canonical NAP** baseline.
-- [ ] Accurate business hours
+

+### 1. Seed Keyword Expansion
+1. Input seed keyword (Korean or English)
+2. Fetch search volume via `our keywords volume "<seed>" --location 2410 --language ko`
+3. Expand with `our keywords ideas "<seed>" --location 2410 --limit 50`
+4. Get autocomplete suggestions via MCP: `mcp__dfs-mcp__dataforseo_labs_google_keyword_suggestions`
+5. Apply Korean suffix expansion if Korean market
+6. Deduplicate and merge results
+
+### 2. Intent Classification & Clustering
+1. Classify each keyword by search intent
+2. Group keywords into topic clusters
+3. Identify pillar topics and supporting terms
+4. Calculate cluster-level metrics (total volume, avg KD)
+
+### 3. Gap Analysis
+1. Pull organic keywords for target: `our keywords for-site <target.com> --location 2410 --limit 100`
+2. Pull organic keywords for competitors: `our keywords for-site <competitor.com> --location 2410 --limit 100`
+3. Identify keywords present in competitors but missing from target
+4. Score opportunities by volume/difficulty ratio
+5. Prioritize by intent alignment with business goals
+

+## Overview
+
+SERP analysis tool for understanding search result landscapes. Detects Google SERP features (featured snippets, PAA, knowledge panels, local pack, video, ads), analyzes Naver SERP composition (blog, cafe, knowledge iN, Smart Store, brand zone, shortform, influencer), maps competitor positions, and scores SERP feature opportunities.
+
+## Quick Start
+
+```bash
+pip install -r scripts/requirements.txt
+
+# Google SERP analysis
+python scripts/serp_analyzer.py --keyword "치과 임플란트" --country kr --json
+
+# Naver SERP analysis
+python scripts/naver_serp_analyzer.py --keyword "치과 임플란트" --json
+```
+
+## Scripts
+
+| Script | Purpose | Key Output |
+|--------|---------|------------|
+| `serp_analyzer.py` | Google SERP feature detection and competitor mapping | SERP features, competitor positions, opportunity scores |
+| `naver_serp_analyzer.py` | Naver SERP composition analysis | Section distribution, content type mapping |
+| `base_client.py` | Shared utilities | RateLimiter, ConfigManager, BaseAsyncClient |
+
+## SERP Analyzer (Google)
+
+```bash
+# Single keyword analysis
+python scripts/serp_analyzer.py --keyword "dental implant cost" --json
+
+# Korean market
+python scripts/serp_analyzer.py --keyword "치과 임플란트 가격" --country kr --json
+
+# Multiple keywords from file
+python scripts/serp_analyzer.py --keywords-file keywords.txt --country kr --json
+
+# Output to file
+python scripts/serp_analyzer.py --keyword "dental implant" --output serp_report.json
+```
+
+**Capabilities**:

+
+# SEO SERP Analysis
+
+## Purpose
+
+Analyze search engine result page composition for Google and Naver. Detect SERP features (featured snippets, PAA, knowledge panels, local pack, video, ads), map competitor positions, score SERP feature opportunities, and analyze Naver section distribution.
+
+## Core Capabilities
+
+1. **Google SERP Feature Detection** - Identify featured snippets, PAA, knowledge panels, local pack, video carousel, ads, image pack, site links, shopping
+2. **Competitor Position Mapping** - Extract domains, positions, content types for top organic results

+
+## MCP Tool Usage
+
+### SEO Data (DataForSEO)
+
+**Primary — our-seo-agent CLI:**
+```bash
+our serp live "<keyword>" --location 2410 --language ko
+our serp competitors <domain> --location 2410
+our serp ranked-keywords <domain> --location 2410 --limit 50
+our serp domain-overview <domain> --location 2410
+```
+
+**Interactive fallback — DataForSEO MCP:**
+```
+mcp__dfs-mcp__serp_organic_live_advanced
+mcp__dfs-mcp__dataforseo_labs_google_serp_competitors
+mcp__dfs-mcp__dataforseo_labs_google_ranked_keywords
+mcp__dfs-mcp__dataforseo_labs_google_domain_rank_overview
+```
+
+### Common Parameters
+- **location_code**: 2410 (Korea), 2840 (US), 2392 (Japan)
+- **language_code**: ko, en, ja
+
+### Notion for Report Storage
+```
+mcp__notion__notion-create-pages: Save analysis report to SEO Audit Log database
+mcp__notion__notion-update-page: Update existing report entries
+```
+
+### Web Tools for Naver Analysis
+```
+WebSearch: Discover Naver search trends
+WebFetch: Fetch Naver SERP HTML for section analysis
+```
+
+## Workflow
+
+### 1. Google SERP Analysis
+1. Fetch SERP via `our serp live "<keyword>" --location 2410 --language ko --format json`
+2. Parse SERP features from response (featured_snippet, people_also_ask, local_pack, etc.)
+3. Map competitor positions from organic_results (domain, URL, title, position)
+4. Classify content type for each result (blog, product, service, news, video)
+5. Calculate opportunity score (0-100) based on feature landscape
+6. Validate search intent from SERP composition
+7. Get competitor domain overview via `our serp domain-overview <competitor> --location 2410`
+
+### 2. Naver SERP Analysis
+1. Fetch Naver search page for the target keyword
+2. Detect SERP sections (blog, cafe, knowledge iN, Smart Store, brand zone, news, encyclopedia, books, shortform, influencer)
+3. Map section priority (above-fold order)
+4. Check brand zone presence and extract brand name
+5. Count items per section
+6. Identify dominant content section
+
+### 3. Report Generation
+1. Compile results into structured JSON
+2. Generate Korean-language report
+3. Save to Notion SEO Audit Log database
+
+## Output Format
+
+```json
+{
+  "keyword": "치과 임플란트",
+  "country": "kr",
+  "serp_features": {
+    "featured_snippet": true,
+    "people_also_ask": true,

+  ],
+  "opportunity_score": 72,
+  "intent_signals": "commercial",
+  "timestamp": "2025-01-01T00:00:00"
+}
+```
+
+## Common SERP Features
+
+| Feature | Impact | Opportunity |
+|---------|--------|-------------|
+| Featured Snippet | High visibility above organic | Optimize content format for snippet capture |
+| People Also Ask | Related question visibility | Create FAQ content targeting PAA |
+| Local Pack | Dominates local intent SERPs | Optimize Google Business Profile |
+| Knowledge Panel | Reduces organic CTR | Focus on brand queries and schema |
+| Video Carousel | Visual SERP real estate | Create video content for keyword |
+| Shopping | Transactional intent signal | Product feed optimization |
+
+## Limitations
+
+- SERP data may have a delay depending on data source (not real-time)
+- Naver SERP HTML structure changes periodically
+- Brand zone detection depends on HTML class patterns
+- Cannot detect personalized SERP results

+## Overview
+
+Position tracking tool for monitoring keyword rankings. Monitors ranking positions, detects position changes with threshold alerts, calculates visibility scores weighted by search volume, compares against competitors, and segments by brand/non-brand keywords.
+
+## Quick Start
+
+```bash
+pip install -r scripts/requirements.txt
+
+# Track positions for a project
+python scripts/position_tracker.py --target https://example.com --json
+
+# Generate ranking report
+python scripts/ranking_reporter.py --target https://example.com --period 30 --json
+```
+
+## Scripts
+
+| Script | Purpose | Key Output |
+|--------|---------|------------|
+| `position_tracker.py` | Monitor keyword ranking positions and detect changes | Position data, change alerts, visibility scores |
+| `ranking_reporter.py` | Generate ranking performance reports with trends | Trend analysis, segment reports, competitor comparison |
+| `base_client.py` | Shared utilities | RateLimiter, ConfigManager, BaseAsyncClient |
+
+## Position Tracker
+
+```bash
+# Get current positions
+python scripts/position_tracker.py --target https://example.com --json
+
+# With change threshold alerts (flag positions that moved +-5 or more)
+python scripts/position_tracker.py --target https://example.com --threshold 5 --json
+
+# Filter by keyword segment
+python scripts/position_tracker.py --target https://example.com --segment brand --json
+
+# Compare with competitors
+python scripts/position_tracker.py --target https://example.com --competitor https://comp1.com --json
+```
+
+**Capabilities**:

+- Position change detection with configurable threshold alerts
+- Visibility score calculation (weighted by search volume)
+- Brand vs non-brand keyword segmentation
+- Competitor rank comparison
+- Keyword segment grouping (by intent, cluster, landing page)
+
+## Ranking Reporter
+
+```bash
+# 30-day ranking report
+python scripts/ranking_reporter.py --target https://example.com --period 30 --json
+
+# Quarterly comparison
+python scripts/ranking_reporter.py --target https://example.com --period 90 --json
+
+# Export with competitor comparison
+python scripts/ranking_reporter.py --target https://example.com --competitor https://comp1.com --period 30 --json
+```
+
+**Capabilities**:
+- Period-over-period ranking trends (improved/declined/stable)
+- Top movers (biggest position gains/losses)
+- Visibility score trend over time
+- Segment-level performance breakdown
+- Competitor overlap and position comparison

+  Keyword position tracking for keyword ranking monitoring.
+  Triggers: rank tracking, position monitoring, keyword rankings, visibility score, ranking report, 키워드 순위, 순위 추적.
+---
+
+# SEO Position Tracking
+
+## Purpose
+
+Monitor keyword ranking positions, detect significant changes, calculate visibility scores, and compare against competitors using our-seo-agent CLI or pre-fetched ranking data. Provides actionable alerts for ranking drops and segment-level performance breakdown.
+
+## Core Capabilities
+
+1. **Position Monitoring** - Retrieve current keyword ranking positions from our-seo-agent CLI or pre-fetched data
+2. **Change Detection** - Detect significant position changes with configurable threshold alerts (severity: critical/high/medium/low)
+3. **Visibility Scoring** - Calculate weighted visibility scores using CTR-curve model (position 1 = 30%, position 2 = 15%, etc.)
+4. **Brand/Non-brand Segmentation** - Automatically classify keywords by brand relevance and search intent type
+5. **Competitor Comparison** - Compare keyword overlap, position gaps, and visibility scores against competitors
+
+## MCP Tool Usage
+
+### SEO Data (DataForSEO)
+
+**Primary — our-seo-agent CLI:**
+```bash
+our serp ranked-keywords <domain> --location 2410 --limit 100
+our keywords volume "<kw1>" "<kw2>" --location 2410 --language ko
+our serp domain-overview <domain> --location 2410
+our serp competitors <domain> --location 2410
+```
+
+**Interactive fallback — DataForSEO MCP:**
+```
+mcp__dfs-mcp__dataforseo_labs_google_ranked_keywords
+mcp__dfs-mcp__dataforseo_labs_google_domain_rank_overview
+mcp__dfs-mcp__dataforseo_labs_google_historical_rank_overview
+mcp__dfs-mcp__dataforseo_labs_google_keyword_overview
+```
+
+### Common Parameters
+- **location_code**: 2410 (Korea), 2840 (US), 2392 (Japan)
+- **language_code**: ko, en, ja
+
+### Notion for Report Storage
+```
+mcp__notion__notion-create-pages: Save tracking reports to SEO Audit Log
+mcp__notion__notion-update-page: Update existing tracking entries
+```
+
+## Workflow
+
+### Phase 1: Data Collection
+1. Fetch current ranked keywords: `our serp ranked-keywords <domain> --location 2410 --limit 100 --format json`
+2. Get domain overview: `our serp domain-overview <domain> --location 2410 --format json`
+3. Get search volumes for tracked keywords: `our keywords volume "<kw1>" "<kw2>" --location 2410`
+4. Fetch competitor positions: `our serp ranked-keywords <competitor> --location 2410 --limit 100`
+5. For historical comparison, use MCP: `mcp__dfs-mcp__dataforseo_labs_google_historical_rank_overview`
+
+### Phase 2: Analysis
+1. Detect position changes against previous period
+2. Generate alerts for changes exceeding threshold
+3. Calculate visibility score weighted by search volume and CTR curve
+4. Segment keywords into brand/non-brand and by intent type
+5. Compare positions against each competitor
+
+### Phase 3: Reporting
+1. Compile position distribution (top3/top10/top20/top50/top100)
+2. Summarize changes (improved/declined/stable/new/lost)
+3. List alerts sorted by severity and search volume
+4. Generate segment-level breakdown
+5. Save report to Notion SEO Audit Log database
+
+## Output Format
+
+```json

+---
+
+# SEO Link Building Diagnosis
+
+## Purpose
+
+Analyze backlink profiles, detect toxic links, find competitor link gaps, track link velocity, and map Korean platform links. Provides actionable link building recommendations.
+
+## Core Capabilities
+
+1. **Backlink Profile Audit** - DR, referring domains, dofollow ratio, anchor distribution
+2. **Toxic Link Detection** - PBN patterns, spam domains, link farm identification
+3. **Competitor Link Gap Analysis** - Domains linking to competitors but not target
+4. **Link Velocity Tracking** - New/lost referring domains over time
+5. **Broken Backlink Recovery** - Find and reclaim broken high-DR backlinks
+6. **Korean Platform Mapping** - Naver Blog, Cafe, Tistory, Brunch, Korean news
+
+## MCP Tool Usage
+
+### SEO Data
+```
+our-seo-agent CLI: Primary backlink data source (future); use --input for pre-fetched JSON
+WebSearch / WebFetch: Supplementary backlink data
+```
+
+### Notion for Report Storage
+```
+mcp__notion__notion-create-pages: Save audit report to SEO Audit Log
+mcp__notion__notion-update-page: Update existing audit entries
+```
+
+## Workflow
+
+### 1. Backlink Profile Audit
+1. Fetch Domain Rating via `site-explorer-domain-rating`
+2. Get backlink stats via `site-explorer-backlinks-stats`
+3. Retrieve referring domains via `site-explorer-referring-domains`
+4. Analyze anchor distribution via `site-explorer-anchors`
+5. Detect toxic links (PBN patterns, spam keywords, suspicious TLDs)
+6. Map Korean platform links from referring domains
+7. Report with issues and recommendations
+
+### 2. Link Gap Analysis
+1. Fetch target referring domains
+2. Fetch competitor referring domains (parallel)
+3. Compute set difference (competitor - target)
+4. Score opportunities by DR, traffic, category
+5. Categorize sources (news, blog, forum, directory, Korean platform)
+6. Rank by feasibility and impact
+7. Report top opportunities with recommendations
+
+### 3. Link Velocity Check
+1. Fetch refdomains-history for last 90 days
+2. Calculate new/lost referring domains per period
+3. Determine velocity trend (growing/stable/declining)
+4. Flag declining velocity as issue
+
+### 4. Broken Backlink Recovery
+1. Fetch broken backlinks via `site-explorer-broken-backlinks`
+2. Sort by DR (highest value first)
+3. Recommend 301 redirects or content recreation
+
+## Output Format
+
+```markdown

+# CLAUDE.md
+
+## Overview
+
+Content strategy tool for SEO-driven content planning. Performs content inventory via sitemap crawl and our-seo-agent CLI, scores content performance, detects content decay, analyzes topic gaps vs competitors, maps topic clusters, and generates content briefs. Supports Korean content patterns (Naver Blog format, review/후기 content).
+
+## Quick Start
+
+```bash
+pip install -r scripts/requirements.txt
+
+# Content audit
+python scripts/content_auditor.py --url https://example.com --json
+
+# Content gap analysis
+python scripts/content_gap_analyzer.py --target https://example.com --competitor https://competitor.com --json
+
+# Generate content brief
+python scripts/content_brief_generator.py --keyword "치과 임플란트 비용" --url https://example.com --json
+```
+
+## Scripts
+
+| Script | Purpose | Key Output |
+|--------|---------|------------|
+| `content_auditor.py` | Content inventory, performance scoring, decay detection | Content inventory with scores and decay flags |
+| `content_gap_analyzer.py` | Topic gap analysis and cluster mapping vs competitors | Missing topics, cluster map, editorial calendar |
+| `content_brief_generator.py` | Generate SEO content briefs with outlines | Brief with outline, keywords, word count targets |
+| `base_client.py` | Shared utilities | RateLimiter, ConfigManager, BaseAsyncClient |
+
+## Content Auditor
+
+```bash
+# Full content audit
+python scripts/content_auditor.py --url https://example.com --json
+
+# Detect decaying content
+python scripts/content_auditor.py --url https://example.com --decay --json
+
+# Filter by content type
+python scripts/content_auditor.py --url https://example.com --type blog --json
+```
+
+**Capabilities**:
+- Content inventory via sitemap crawl + our-seo-agent CLI or pre-fetched data
+- Performance scoring (traffic, rankings, backlinks)
+- Content decay detection (pages losing traffic over time)
+- Content type classification (blog, product, service, landing, resource)
+- Word count and freshness assessment
+- Korean content format analysis (Naver Blog style, 후기/review content)
+
+## Content Gap Analyzer
+
+```bash
+# Gap analysis vs competitor
+python scripts/content_gap_analyzer.py --target https://example.com --competitor https://comp1.com --json
+
+# With topic cluster mapping
+python scripts/content_gap_analyzer.py --target https://example.com --competitor https://comp1.com --clusters --json
+```
+
+**Capabilities**:
+- Topic gap identification vs competitors
+- Topic cluster mapping (pillar + cluster pages)
+- Content freshness comparison
+- Content volume comparison
+- Editorial calendar generation with priority scoring
+- Korean content opportunity detection
+
+## Content Brief Generator
+
+```bash
+# Generate brief for keyword
+python scripts/content_brief_generator.py --keyword "치과 임플란트 비용" --url https://example.com --json
+
+# With competitor analysis
+python scripts/content_brief_generator.py --keyword "dental implant cost" --url https://example.com --competitors 5 --json
+```
+
+**Capabilities**:
+- Content outline generation with H2/H3 structure
+- Target keyword list (primary + secondary + LSI)
+- Word count recommendation based on top-ranking pages
+- Competitor content analysis (structure, word count, topics covered)
+- Internal linking suggestions
+- Korean content format recommendations
+
+## Data Sources
+
+| Source | Purpose |
+|--------|---------|
+| `our-seo-agent` CLI | Primary data source (future); use `--input` for pre-fetched JSON |
+| WebSearch / WebFetch | Supplementary live data |
+| Notion MCP | Save audit report to database |
+
+## Output Format
+
+```json
+{
+  "url": "https://example.com",
+  "content_inventory": {
+    "total_pages": 150,
+    "by_type": {"blog": 80, "product": 40, "service": 20, "other": 10},

+  Content strategy and planning for SEO. Triggers: content audit, content strategy, content gap, topic clusters, content brief, editorial calendar, content decay, 콘텐츠 전략, 콘텐츠 감사.
+---
+
+# SEO Content Strategy
+
+## Purpose
+
+Audit existing content performance, identify topic gaps vs competitors, map topic clusters, detect content decay, and generate SEO content briefs. Supports Korean content patterns (Naver Blog format, 후기/review content, 추천 listicles).
+
+## Core Capabilities
+
+1. **Content Audit** - Inventory, performance scoring, decay detection
+2. **Content Gap Analysis** - Topic gaps vs competitors, cluster mapping
+3. **Content Brief Generation** - Outlines, keywords, word count targets
+4. **Editorial Calendar** - Prioritized content creation schedule
+5. **Korean Content Patterns** - Naver Blog style, 후기, 추천 format analysis
+
+## MCP Tool Usage
+
+### SEO Data
+```
+our-seo-agent CLI: Primary content/traffic data source (future); use --input for pre-fetched JSON
+WebSearch / WebFetch: Supplementary content data
+```
+
+### WebSearch for Content Research
+```
+WebSearch: Research content topics and competitor strategies
+WebFetch: Analyze competitor page content and structure
+```
+
+### Notion for Report Storage
+```
+notion-create-pages: Save audit reports to SEO Audit Log
+```
+
+## Workflow
+
+### 1. Content Audit
+1. Crawl sitemap to discover all content URLs
+2. Fetch top pages data via our-seo-agent CLI, pre-fetched JSON, or WebSearch
+3. Classify content types (blog, product, service, landing, resource)
+4. Score each page performance (0-100 composite)
+5. Detect decaying content (traffic decline patterns)
+6. Analyze freshness distribution (fresh/aging/stale)
+7. Identify Korean content patterns (후기, 추천, 방법 formats)
+8. Generate recommendations
+
+### 2. Content Gap Analysis
+1. Gather target site keywords via our-seo-agent CLI or pre-fetched data
+2. Gather competitor top pages and keywords
+3. Identify topics present in competitors but missing from target
+4. Score gaps by priority (traffic potential + competition coverage)
+5. Build topic clusters using TF-IDF + hierarchical clustering
+6. Generate editorial calendar with priority and dates
+7. Detect Korean market content opportunities
+
+### 3. Content Brief Generation
+1. Analyze top 5-10 ranking pages for target keyword
+2. Extract headings, word counts, content features (FAQ, images, video)
+3. Build recommended H2/H3 outline from competitor patterns
+4. Suggest primary, secondary, and LSI keywords
+5. Calculate target word count (avg of top 5 +/- 20%)
+6. Find internal linking opportunities on the target site
+7. Detect search intent (informational, commercial, transactional, navigational)
+8. Add Korean format recommendations based on intent
+
+## Output Format
+
+```markdown
+## Content Audit: [domain]
+
+### Content Inventory
+- Total pages: [count]
+- By type: blog [n], product [n], service [n], other [n]
+- Average performance score: [score]/100
+
+### Top Performers
+1. [score] [url] (traffic: [n])
+...
+
+### Decaying Content
+1. [decay rate] [url] (traffic: [n])
+...
+
+### Content Gaps vs Competitors
+1. [priority] [topic] (est. traffic: [n], difficulty: [level])
+...
+
+### Topic Clusters
+1. **[Pillar Topic]** ([n] subtopics)
+   - [subtopic 1]
+   - [subtopic 2]
+
+### Editorial Calendar
+- [date] [topic] ([type], [word count], priority: [level])
+...
+
+### Recommendations
+1. [Priority actions]
+```
+
+## Common Issues
+
+| Issue | Impact | Fix |
+|-------|--------|-----|
+| No blog content | High | Build blog content strategy with topic clusters |
+| Content decay (traffic loss) | High | Refresh and update declining pages |
+| Missing competitor topics | Medium | Create content for high-priority gaps |
+| No 후기/review content | Medium | Add Korean review-style content for conversions |
+| Stale content (>12 months) | Medium | Update or consolidate outdated pages |
+| No topic clusters | Medium | Organize content into pillar/cluster structure |
+| Missing FAQ sections | Low | Add FAQ schema for featured snippet opportunities |
+
+## Limitations
+
+- our-seo-agent CLI or pre-fetched JSON required for traffic and keyword data
+- Competitor analysis limited to publicly available content
+- Content decay detection uses heuristic without historical data in standalone mode
+- Topic clustering requires minimum 3 topics per cluster
+- Word count analysis requires accessible competitor pages (no JS rendering)
+
+## Notion Output (Required)
+
+All audit reports MUST be saved to OurDigital SEO Audit Log:
+- **Database ID**: `2c8581e5-8a1e-8035-880b-e38cefc2f3ef`
+- **Properties**: Issue (title), Site (url), Category, Priority, Found Date, Audit ID
+- **Language**: Korean with English technical terms
+- **Audit ID Format**: CONTENT-YYYYMMDD-NNN
