## 🏗️ Architecture

### Core Design Pattern: Platform Adaptors

The codebase uses the **Strategy Pattern** with a factory method to support **16 platforms** across 4 categories:

```
src/skill_seekers/cli/adaptors/
├── __init__.py          # Factory: get_adaptor(target/format)
├── base.py              # Abstract base class
# LLM Platforms (3)
├── claude.py            # Claude AI (ZIP + YAML)
├── gemini.py            # Google Gemini (tar.gz)
├── openai.py            # OpenAI ChatGPT (ZIP + Vector Store)
# RAG Frameworks (3)
├── langchain.py         # LangChain Documents
├── llama_index.py       # LlamaIndex TextNodes
├── haystack.py          # Haystack Documents
# Vector Databases (5)
├── chroma.py            # ChromaDB
├── faiss_helpers.py     # FAISS
├── qdrant.py            # Qdrant
├── weaviate.py          # Weaviate
# AI Coding Assistants (4 - via Claude format + config files)
# - Cursor, Windsurf, Cline, Continue.dev
# Generic (1)
├── markdown.py          # Generic Markdown (ZIP)
└── streaming_adaptor.py # Streaming data ingest
```

**Key Methods:**
- `package(skill_dir, output_path)` - Platform-specific packaging
- `upload(package_path, api_key)` - Platform-specific upload (where applicable)
- `enhance(skill_dir, mode)` - AI enhancement with platform-specific models
- `export(skill_dir, format)` - Export to RAG/vector DB formats

### Data Flow (5 Phases)

1. **Scrape Phase** (`doc_scraper.py:scrape_all()`)
   - BFS traversal from base_url
   - Output: `output/{name}_data/pages/*.json`

2. **Build Phase** (`doc_scraper.py:build_skill()`)
   - Load pages → Categorize → Extract patterns
   - Output: `output/{name}/SKILL.md` + `references/*.md`

3. **Enhancement Phase** (optional, `enhance_skill_local.py`)
   - LLM analyzes references → Rewrites SKILL.md
   - Platform-specific models (Sonnet 4, Gemini 2.0, GPT-4o)

4. **Package Phase** (`package_skill.py` → adaptor)
   - Platform adaptor packages in appropriate format
   - Output: `.zip` or `.tar.gz`

5. **Upload Phase** (optional, `upload_skill.py` → adaptor)
   - Upload via platform API

## 🔧 Key Implementation Details

### CLI Architecture (Git-style)

**Entry point:** `src/skill_seekers/cli/main.py`

The unified CLI modifies `sys.argv` and calls existing `main()` functions to maintain backward compatibility:

```python
# Example: skill-seekers scrape --config react.json
# Transforms to: doc_scraper.main() with modified sys.argv
```

**Subcommands:** create, scrape, github, pdf, unified, codebase, enhance, enhance-status, package, upload, estimate, install, install-agent, patterns, how-to-guides

### NEW: Unified `create` Command

**The recommended way to create skills** - Auto-detects source type and provides progressive help disclosure:

```bash
# Auto-detection examples
skill-seekers create https://docs.react.dev/         # → Web scraping
skill-seekers create facebook/react                  # → GitHub analysis
skill-seekers create ./my-project                    # → Local codebase
skill-seekers create tutorial.pdf                    # → PDF extraction
skill-seekers create configs/react.json              # → Multi-source

# Progressive help system
skill-seekers create --help           # Shows universal args only (13 flags)
skill-seekers create --help-web       # Shows web-specific options
skill-seekers create --help-github    # Shows GitHub-specific options
skill-seekers create --help-local     # Shows local analysis options
skill-seekers create --help-pdf       # Shows PDF extraction options
skill-seekers create --help-advanced  # Shows advanced/rare options
skill-seekers create --help-all       # Shows all 120+ flags

# Universal flags work for ALL sources
skill-seekers create <source> -p quick                    # Preset (-p shortcut)
skill-seekers create <source> --enhance-level 2           # AI enhancement (0-3)
skill-seekers create <source> --chunk-for-rag             # RAG chunking
skill-seekers create <source> --dry-run                   # Preview
```

**Key improvements:**
- **Single command** replaces scrape/github/analyze for most use cases
- **Smart detection** - No need to specify source type
- **Progressive disclosure** - Default help shows 13 flags, detailed help available
- **-p shortcut** - Quick preset selection (`-p quick|standard|comprehensive`)
- **Universal features** - RAG chunking, dry-run, presets work everywhere

**Recent Additions:**
- `create` - **NEW:** Unified command with auto-detection and progressive help
- `codebase` - Local codebase analysis without GitHub API (C2.x + C3.x features)
- `enhance-status` - Monitor background/daemon enhancement processes
- `patterns` - Detect design patterns in code (C3.1)
- `how-to-guides` - Generate educational guides from tests (C3.3)

### Platform Adaptor Usage

```python
from skill_seekers.cli.adaptors import get_adaptor

# Get platform-specific adaptor
adaptor = get_adaptor('gemini')  # or 'claude', 'openai', 'markdown'

# Package skill
adaptor.package(skill_dir='output/react/', output_path='output/')

# Upload to platform
adaptor.upload(
    package_path='output/react-gemini.tar.gz',
    api_key=os.getenv('GOOGLE_API_KEY')
)

# AI enhancement
adaptor.enhance(skill_dir='output/react/', mode='api')
```

  - Framework detection (Unity, Unreal, Godot)

**Key Architecture Decision (BREAKING in v2.5.2):**
- Changed from opt-in (`--build-*`) to opt-out (`--skip-*`) flags
- All analysis features now ON by default for maximum value
- Backward compatibility warnings for deprecated flags

### Smart Categorization Algorithm

Located in `doc_scraper.py:smart_categorize()`:
- Scores pages against category keywords
- 3 points for URL match, 2 for title, 1 for content
- Threshold of 2+ for categorization
- Auto-infers categories from URL segments if none provided
- Falls back to "other" category

### Language Detection

Located in `doc_scraper.py:detect_language()`:
1. CSS class attributes (`language-*`, `lang-*`)
2. Heuristics (keywords like `def`, `const`, `func`)

### Configuration File Structure

Configs (`configs/*.json`) define scraping behavior:

```json
{
  "name": "framework-name",
  "description": "When to use this skill",
  "base_url": "https://docs.example.com/",
  "selectors": {
    "main_content": "article",  // CSS selector
    "title": "h1",
    "code_blocks": "pre code"
  },
  "url_patterns": {
    "include": ["/docs"],
    "exclude": ["/blog"]
  },
  "categories": {
    "getting_started": ["intro", "quickstart"],
    "api": ["api", "reference"]
  },
  "rate_limit": 0.5,
  "max_pages": 500
}
```

## 🧪 Testing Guidelines

### Test Coverage Requirements

- Core features: 100% coverage required
- Platform adaptors: Each platform has dedicated tests
- MCP tools: All 18 tools must be tested
- Integration tests: End-to-end workflows

### Test Markers (from pytest.ini_options)

The project uses pytest markers to categorize tests:

```bash
# Run only fast unit tests (default)
pytest tests/ -v

# Include slow tests (>5 seconds)
pytest tests/ -v -m slow

# Run integration tests (requires external services)
pytest tests/ -v -m integration

# Run end-to-end tests (resource-intensive, creates files)
pytest tests/ -v -m e2e

# Run tests requiring virtual environment setup
pytest tests/ -v -m venv

# Run bootstrap feature tests
pytest tests/ -v -m bootstrap

# Skip slow and integration tests (fastest)
pytest tests/ -v -m "not slow and not integration"
```

### Test Execution Strategy

**By default, only fast tests run**. Use markers to control test execution:

```bash
# Default: Only fast tests (skip slow/integration/e2e)
pytest tests/ -v

# Include slow tests (>5 seconds)
pytest tests/ -v -m slow

# Include integration tests (requires external services)
pytest tests/ -v -m integration

# Include resource-intensive e2e tests (creates files)
pytest tests/ -v -m e2e

# Run ONLY fast tests (explicit)
pytest tests/ -v -m "not slow and not integration and not e2e"

# Run everything (CI does this)
pytest tests/ -v -m ""
```

**When to use which:**
- **Local development:** Default (fast tests only) - `pytest tests/ -v`
- **Pre-commit:** Fast tests - `pytest tests/ -v`
- **Before PR:** Include slow + integration - `pytest tests/ -v -m "not e2e"`
- **CI validation:** All tests run automatically

### Key Test Files

- `test_scraper_features.py` - Core scraping functionality

### Optional Dependencies

**Project uses PEP 735 `[dependency-groups]` (Python 3.13+)**:
- Replaces deprecated `tool.uv.dev-dependencies`
- Dev dependencies: `[dependency-groups] dev = [...]` in pyproject.toml
- Install with: `pip install -e .` (installs only core deps)
- Install dev deps: See CI workflow or manually install pytest, ruff, mypy

**Note on video dependencies:** `easyocr` and GPU-specific PyTorch builds are **not** included in the `video-full` optional dependency group. They are installed at runtime by `skill-seekers video --setup`, which auto-detects the GPU (CUDA/ROCm/MPS/CPU) and installs the correct builds.

```toml
[project.optional-dependencies]
gemini = ["google-generativeai>=0.8.0"]
openai = ["openai>=1.0.0"]
all-llms = ["google-generativeai>=0.8.0", "openai>=1.0.0"]

[dependency-groups]  # PEP 735 (replaces tool.uv.dev-dependencies)
dev = [
    "pytest>=8.4.2",
    "pytest-asyncio>=0.24.0",
    "pytest-cov>=7.0.0",
    "coverage>=7.11.0",
]
```

## 🚨 Critical Development Notes

### Must Run Before Tests

```bash
# REQUIRED: Install package before running tests
pip install -e .

# Why: src/ layout requires package installation
# Without this, imports will fail
```

### Never Skip Tests

Per user instructions in `~/.claude/CLAUDE.md`:
- "never skip any test. always make sure all test pass"
- All 2,540 tests must pass before commits
- Run full test suite: `pytest tests/ -v`
- New tests added for create command and CLI refactor work

### Platform-Specific Dependencies

Platform dependencies are optional (install only what you need):

```bash
# Install specific platform support
pip install -e ".[gemini]"         # Google Gemini
pip install -e ".[openai]"         # OpenAI ChatGPT
pip install -e ".[chroma]"         # ChromaDB
pip install -e ".[weaviate]"       # Weaviate
pip install -e ".[s3]"             # AWS S3
pip install -e ".[gcs]"            # Google Cloud Storage
pip install -e ".[azure]"          # Azure Blob Storage
pip install -e ".[mcp]"            # MCP integration
pip install -e ".[all]"            # Everything (16 platforms + cloud + embedding)

# Or install from PyPI:
pip install skill-seekers[gemini]    # Google Gemini support
pip install skill-seekers[openai]    # OpenAI ChatGPT support
pip install skill-seekers[all-llms]  # All LLM platforms
pip install skill-seekers[chroma]    # ChromaDB support
pip install skill-seekers[weaviate]  # Weaviate support
pip install skill-seekers[s3]        # AWS S3 support
pip install skill-seekers[all]       # All optional dependencies
```

### AI Enhancement Modes

AI enhancement transforms basic skills (2-3/10) into production-ready skills (8-9/10). Two modes available:

**API Mode** (default if ANTHROPIC_API_KEY is set):
- Direct Claude API calls (fast, efficient)
- Cost: ~$0.15-$0.30 per skill
- Perfect for CI/CD automation
- Requires: `export ANTHROPIC_API_KEY=sk-ant-...`

**LOCAL Mode** (fallback if no API key):
- Uses Claude Code CLI (your existing Max plan)
- Free! No API charges
- 4 execution modes:
  - Headless (default): Foreground, waits for completion
  - Background (`--background`): Returns immediately
  - Daemon (`--daemon`): Fully detached with nohup
  - Terminal (`--interactive-enhancement`): Opens new terminal (macOS)
- Status monitoring: `skill-seekers enhance-status output/react/ --watch`
- Timeout configuration: `--timeout 300` (seconds)

### Enhancement Flag Consolidation (Phase 1)

**IMPORTANT CHANGE:** Three enhancement flags have been unified into a single granular control:

**Old flags (deprecated):**
- `--enhance` - Enable AI enhancement
- `--enhance-local` - Use LOCAL mode (Claude Code)
- `--api-key KEY` - Anthropic API key

**New unified flag:**
- `--enhance-level LEVEL` - Granular AI enhancement control (0-3, default: 2)
  - `0` - Disabled, no AI enhancement
  - `1` - SKILL.md only (core documentation)
  - `2` - + Architecture + Config + Docs (default, balanced)
  - `3` - Full enhancement (all features, comprehensive)

**Auto-detection:** Mode (API vs LOCAL) is auto-detected:
- If `ANTHROPIC_API_KEY` is set → API mode
- Otherwise → LOCAL mode (Claude Code Max)

**Examples:**
```bash
# Auto-detect mode, default enhancement level (2)
skill-seekers create https://docs.react.dev/

# Disable enhancement
skill-seekers create facebook/react --enhance-level 0

# SKILL.md only (fast)
skill-seekers create ./my-project --enhance-level 1

# Full enhancement (comprehensive)
skill-seekers create tutorial.pdf --enhance-level 3

# Force LOCAL mode with specific level
skill-seekers enhance output/react/ --mode LOCAL --enhance-level 2

# Background with status monitoring
skill-seekers enhance output/react/ --background
skill-seekers enhance-status output/react/ --watch
```

**Migration:** Old flags still work with deprecation warnings, will be removed in v4.0.0.

See `docs/ENHANCEMENT_MODES.md` for detailed documentation.

### Git Workflow

**Git Workflow Notes:**
- Main branch: `main`
- Development branch: `development`
- Always create feature branches from `development`
- Branch naming: `feature/{task-id}-{description}` or `feature/{category}`

**To see current status:** `git status`

### CI/CD Pipeline

The project has GitHub Actions workflows in `.github/workflows/`:

**tests.yml** - Runs on every push and PR to `main` or `development`:

1. **Lint Job** (Python 3.12, Ubuntu):
   - `ruff check src/ tests/` - Code linting with GitHub annotations
   - `ruff format --check src/ tests/` - Format validation
   - `mypy src/skill_seekers` - Type checking (continue-on-error)

2. **Test Job** (Matrix):
   - **OS:** Ubuntu + macOS
   - **Python:** 3.10, 3.11, 3.12
   - **Exclusions:** macOS + Python 3.10 (speed optimization)
   - **Steps:**
     - Install dependencies + `pip install -e .`
     - Run CLI tests (scraper, config, integration)
     - Run MCP server tests
     - Generate coverage report → Upload to Codecov

3. **Summary Job** - Single status check for branch protection
   - Ensures both lint and test jobs succeed
   - Provides single "All Checks Complete" status

**release.yml** - Triggers on version tags (e.g., `v2.9.0`):
- Builds package with `uv build`
- Publishes to PyPI with `uv publish`
- Creates GitHub release

**Local Pre-Commit Validation**

Run the same checks as CI before pushing:

```bash
# 1. Code quality (matches lint job) - WITH AUTO-FIX
uvx ruff check --fix --unsafe-fixes src/ tests/  # Auto-fix issues
uvx ruff format src/ tests/                      # Auto-format
uvx ruff check src/ tests/                       # Verify clean
uvx ruff format --check src/ tests/              # Verify formatted
mypy src/skill_seekers

# 2. Tests (matches test job)
pip install -e .
pytest tests/ -v --cov=src/skill_seekers --cov-report=term

# 3. If all pass, you're good to push!
git add -A  # Stage any auto-fixes
git commit --amend --no-edit  # Add fixes to commit (or new commit)
git push origin feature/my-feature
```

**Branch Protection Rules:**
- **main:** Requires tests + 1 review, only maintainers merge
- **development:** Requires tests to pass, default target for PRs

**Common CI Failure Patterns and Fixes**

If CI fails after your changes, follow this debugging checklist:

```bash
# 1. Fix linting errors automatically
uvx ruff check --fix --unsafe-fixes src/ tests/

# 2. Fix formatting issues
uvx ruff format src/ tests/

# 3. Check for remaining issues
uvx ruff check src/ tests/
uvx ruff format --check src/ tests/

# 4. Verify tests pass locally
pip install -e .
pytest tests/ -v

# 5. Push fixes
git add -A
git commit -m "fix: resolve CI linting/formatting issues"
git push
```

**Critical dependency patterns to check:**
- **MCP version mismatch**: Ensure `requirements.txt` and `pyproject.toml` have matching MCP versions
- **Missing module-level imports**: If a tool file imports a module at top level (e.g., `import yaml`), that module MUST be in core dependencies
- **Try/except ImportError**: Silent failures in try/except blocks can hide missing dependencies

**Timing-sensitive tests:**
- Benchmark tests may fail on slower CI runners (macOS)
- If a test times out or exceeds threshold only in CI, consider relaxing the threshold
- Local passing doesn't guarantee CI passing for performance tests

## 🚨 Common Pitfalls & Solutions

### 1. Import Errors
**Problem:** `ModuleNotFoundError: No module named 'skill_seekers'`

**Solution:** Must install package first due to src/ layout
```bash
pip install -e .
```

**Why:** The src/ layout prevents imports from repo root. Package must be installed.

### 2. Tests Fail with "No module named..."
**Problem:** Package not installed in test environment

**Solution:** CI runs `pip install -e .` before tests - do the same locally
```bash
pip install -e .
pytest tests/ -v
```

### 3. Platform-Specific Dependencies Not Found
**Problem:** `ModuleNotFoundError: No module named 'google.generativeai'`

**Solution:** Install platform-specific dependencies
```bash
pip install -e ".[gemini]"   # For Gemini
pip install -e ".[openai]"   # For OpenAI
pip install -e ".[all-llms]" # For all platforms
```

### 4. Git Branch Confusion
**Problem:** PR targets `main` instead of `development`

**Solution:** Always create PRs targeting `development` branch
```bash
git checkout development
git pull upstream development
git checkout -b feature/my-feature
# ... make changes ...
git push origin feature/my-feature
# Create PR: feature/my-feature → development
```

**Important:** See `CONTRIBUTING.md` for complete branch workflow.

### 5. Tests Pass Locally But Fail in CI
**Problem:** Different Python version or missing dependency

**Solution:** Test with multiple Python versions locally
```bash
# CI tests: Python 3.10, 3.11, 3.12 on Ubuntu + macOS
# Use pyenv or docker to test locally:
pyenv install 3.10.13 3.11.7 3.12.1

pyenv local 3.10.13
pip install -e . && pytest tests/ -v

pyenv local 3.11.7
pip install -e . && pytest tests/ -v

pyenv local 3.12.1
pip install -e . && pytest tests/ -v
```

### 6. Enhancement Not Working
**Problem:** AI enhancement fails or hangs

**Solutions:**
```bash
# Check if API key is set
echo $ANTHROPIC_API_KEY

# Try LOCAL mode instead (uses Claude Code Max, no API key needed)
skill-seekers enhance output/react/ --mode LOCAL

# Monitor enhancement status for background jobs
skill-seekers enhance-status output/react/ --watch
```

### 7. Rate Limit Errors from GitHub
**Problem:** `403 Forbidden` from GitHub API

**Solutions:**
```bash
# Check current rate limit
curl -H "Authorization: token $GITHUB_TOKEN" https://api.github.com/rate_limit

# Configure multiple GitHub profiles (recommended)
skill-seekers config --github

# Use specific profile
skill-seekers github --repo owner/repo --profile work

# Test all configured tokens
skill-seekers config --test
```

### 8. Confused About Command Options
**Problem:** "Too many flags!" or "Which flags work with which sources?"

**Solution:** Use the progressive disclosure help system in the `create` command:
```bash
# Start with universal options (13 flags)
skill-seekers create --help

# Need web scraping options?
skill-seekers create --help-web

# GitHub-specific flags?
skill-seekers create --help-github

# See ALL options (120+ flags)?
skill-seekers create --help-all

# Quick preset shortcut
skill-seekers create <source> -p quick
skill-seekers create <source> -p standard
skill-seekers create <source> -p comprehensive
```

**Why:** The create command shows only relevant flags by default to reduce cognitive load.

**Legacy commands** (scrape, github, analyze) show all flags in one help screen - use them if you prefer that style.

### 9. CI Passes Locally But Fails in GitHub Actions
**Problem:** Ruff check/format or tests pass locally but fail in CI

**Common causes:**
1. **Dependency version mismatch** - `requirements.txt` vs `pyproject.toml` conflicts
   ```bash
   # Check both files have matching versions for core deps
   grep "mcp" requirements.txt pyproject.toml
   grep "PyYAML" requirements.txt pyproject.toml
   ```

2. **Module imported but not declared** - File imports module at top level but it's not in dependencies
   ```bash
   # Search for imports that might not be in dependencies
   grep -r "^import yaml" src/
   grep -r "^from yaml" src/
   # Ensure PyYAML is in pyproject.toml core dependencies
   ```

3. **Ruff version differences** - Local ruff vs CI ruff may have different rules
   ```bash
   # Use uvx to match CI's ruff version
   uvx ruff check src/ tests/
   uvx ruff format src/ tests/
   ```

**Solution:**
```bash
# Run CI validation commands exactly as CI does
pip install -e .  # Fresh install
uvx ruff check src/ tests/  # Use uvx, not local ruff
uvx ruff format --check src/ tests/
pytest tests/ -v
```

   ```python
   from .base import BaseAdaptor

   class MyPlatformAdaptor(BaseAdaptor):
       def package(self, skill_dir, output_path, **kwargs):
           # Platform-specific packaging

### Modifying Core Scraping Logic

**Key files by feature:**

| Feature | File | Size | Notes |
|---------|------|------|-------|
| Doc scraping | `src/skill_seekers/cli/doc_scraper.py` | ~90KB | Main scraper, BFS traversal |
| GitHub scraping | `src/skill_seekers/cli/github_scraper.py` | ~56KB | Repo analysis + metadata |
| GitHub API | `src/skill_seekers/cli/github_fetcher.py` | ~17KB | Rate limit handling |
| PDF extraction | `src/skill_seekers/cli/pdf_scraper.py` | Medium | PyMuPDF + OCR |
| Code analysis | `src/skill_seekers/cli/code_analyzer.py` | ~65KB | Multi-language AST parsing |
| Pattern detection | `src/skill_seekers/cli/pattern_recognizer.py` | Medium | C3.1 - 10 GoF patterns |
| Test extraction | `src/skill_seekers/cli/test_example_extractor.py` | Medium | C3.2 - 5 categories |

| Signal flow | `src/skill_seekers/cli/signal_flow_analyzer.py` | Medium | C3.10 - Godot-specific |

**Always add tests when modifying core logic!**

### Modifying the Unified Create Command

**The create command uses a modular argument system:**

**Files involved:**
1. **Parser:** `src/skill_seekers/cli/parsers/create_parser.py`
   - Defines help text and formatter
   - Registers help mode flags (`--help-web`, `--help-github`, etc.)
   - Uses custom `NoWrapFormatter` for better help display

2. **Arguments:** `src/skill_seekers/cli/arguments/create.py`
   - Three tiers of arguments:
     - `UNIVERSAL_ARGUMENTS` (13 flags) - Work for all sources
     - Source-specific dicts (`WEB_ARGUMENTS`, `GITHUB_ARGUMENTS`, etc.)
     - `ADVANCED_ARGUMENTS` - Rare/advanced options
   - `add_create_arguments(parser, mode)` - Multi-mode argument addition

3. **Source Detection:** `src/skill_seekers/cli/source_detector.py` (if implemented)
   - Auto-detect source type from input
   - Pattern matching (URLs, GitHub repos, file extensions)

4. **Main Logic:** `src/skill_seekers/cli/create_command.py` (if implemented)
   - Route to appropriate scraper based on detected type
   - Argument validation and compatibility checking

**When adding new arguments:**
- Universal args → `UNIVERSAL_ARGUMENTS` in `arguments/create.py`
- Source-specific → Appropriate dict (`WEB_ARGUMENTS`, etc.)
- Always update help text and add tests

**Example: Adding a new universal flag:**
```python
# In arguments/create.py
UNIVERSAL_ARGUMENTS = {
    # ... existing args ...
    "my_flag": {
        "flags": ("--my-flag", "-m"),
        "kwargs": {
            "action": "store_true",
            "help": "Description of my flag",
        },
    },
}
```

### Adding MCP Tools

**Files to modify:**
1. **Add tool function:** `src/skill_seekers/mcp/tools/{category}_tools.py`

2. **Register tool:** `src/skill_seekers/mcp/server.py`
   ```python
   @mcp.tool()
   def my_new_tool(param: str) -> str:
       """Tool description."""
       # Implementation
   ```

3. **Add tests:** `tests/test_mcp_fastmcp.py`

4. **Update count:** README.md (currently 18 tools)

## 🎯 Project-Specific Best Practices

1. **Prefer the unified `create` command** - Use `skill-seekers create <source>` over legacy commands for consistency
2. **Always use platform adaptors** - Never hardcode platform-specific logic
3. **Test all platforms** - Changes must work for all 16 platforms (was 4 in v2.x)
4. **Maintain backward compatibility** - Legacy commands (scrape, github, analyze) must still work
5. **Document API changes** - Update CHANGELOG.md for every release
6. **Keep dependencies optional** - Platform-specific deps are optional (RAG, cloud, etc.)
7. **Use src/ layout** - Proper package structure with `pip install -e .`
8. **Run tests before commits** - Per user instructions, never skip tests (1,765+ tests must pass)
9. **RAG-first mindset** - v3.0.0 is the universal preprocessor for AI systems
10. **Export format clarity** - Use `--format` for RAG/vector DBs, `--target` for LLM platforms
11. **Test with real integrations** - Verify exports work with actual LangChain, ChromaDB, etc.
12. **Progressive disclosure** - When adding flags, categorize as universal/source-specific/advanced

## 🐛 Debugging Tips

### Enable Verbose Logging

```bash
# Set environment variable for debug output
export SKILL_SEEKERS_DEBUG=1
skill-seekers scrape --config configs/react.json
```

### Test Single Function/Module

Run Python modules directly for debugging:
```bash
# Run modules with --help to see options
python -m skill_seekers.cli.doc_scraper --help
python -m skill_seekers.cli.github_scraper --repo facebook/react --dry-run
python -m skill_seekers.cli.package_skill --help

# Test MCP server directly
python -m skill_seekers.mcp.server_fastmcp
```

### Use pytest with Debugging

```bash
# Drop into debugger on failure
pytest tests/test_scraper_features.py --pdb

# Show print statements (normally suppressed)
pytest tests/test_scraper_features.py -s

# Verbose test output (shows full diff, more details)
pytest tests/test_scraper_features.py -vv

# Run only failed tests from last run
pytest tests/ --lf

# Run until first failure (stop immediately)
pytest tests/ -x

# Show local variables on failure
pytest tests/ -l
```

### Debug Specific Test

```bash
# Run single test with full output
pytest tests/test_scraper_features.py::test_detect_language -vv -s

# With debugger
pytest tests/test_scraper_features.py::test_detect_language --pdb
```

### Check Package Installation

```bash
# Verify package is installed
pip list | grep skill-seekers

# Check installation mode (should show editable location)
pip show skill-seekers

# Verify imports work
python -c "import skill_seekers; print(skill_seekers.__version__)"

# Check CLI entry points
which skill-seekers
skill-seekers --version
```

### Common Error Messages & Solutions

**"ModuleNotFoundError: No module named 'skill_seekers'"**
→ **Solution:** `pip install -e .`
→ **Why:** src/ layout requires package installation

**"403 Forbidden" from GitHub API**
→ **Solution:** Rate limit hit, set `GITHUB_TOKEN` or use `skill-seekers config --github`
→ **Check limit:** `curl -H "Authorization: token $GITHUB_TOKEN" https://api.github.com/rate_limit`

**"SKILL.md enhancement failed"**
→ **Solution:** Check if `ANTHROPIC_API_KEY` is set, or use `--mode LOCAL`
→ **Monitor:** `skill-seekers enhance-status output/react/ --watch`

**"No such file or directory: 'configs/myconfig.json'"**
→ **Solution:** Config path resolution order:
  1. Exact path as provided
  2. `./configs/` (current directory)
  3. `~/.config/skill-seekers/configs/` (user config)
  4. SkillSeekersWeb.com API (presets)

**"pytest: command not found"**
→ **Solution:** Install dev dependencies
```bash
pip install pytest pytest-asyncio pytest-cov coverage
# Or: pip install -e ".[dev]"  (if available)
```

**"ruff: command not found"**
→ **Solution:** Install ruff
```bash
pip install ruff
# Or use uvx: uvx ruff check src/
```

### Debugging Scraping Issues

**No content extracted?**
```python
# Test selectors in Python
from bs4 import BeautifulSoup
import requests

url = "https://docs.example.com/page"
soup = BeautifulSoup(requests.get(url).content, 'html.parser')

# Try different selectors
print(soup.select_one('article'))
print(soup.select_one('main'))
print(soup.select_one('div[role="main"]'))
print(soup.select_one('.documentation-content'))
```

**Categories not working?**
- Check `categories` in config has correct keywords
- Run with `--dry-run` to see categorization without scraping
- Enable debug mode: `export SKILL_SEEKERS_DEBUG=1`

### Profiling Performance

```bash
# Profile scraping performance
python -m cProfile -o profile.stats -m skill_seekers.cli.doc_scraper --config configs/react.json --max-pages 10

# Analyze profile
python -m pstats profile.stats
# In pstats shell:
# > sort cumtime
# > stats 20
```

## 🎓 Understanding the Codebase

### Why src/ Layout?

Modern Python best practice (PEP 517/518):
- Prevents accidental imports from repo root
- Forces proper package installation
- Better isolation between package and tests
- Required: `pip install -e .` before running tests

### Why Platform Adaptors?

Strategy pattern benefits:
- Single codebase supports 4 platforms
- Platform-specific optimizations (format, APIs, models)
- Easy to add new platforms (implement BaseAdaptor)
- Clean separation of concerns
- Testable in isolation

### Why Git-style CLI?

User experience benefits:
- Familiar to developers (like `git`)
- Single entry point: `skill-seekers`
- Backward compatible: individual tools still work
- Cleaner than multiple separate commands
- Easier to document and teach

### Three-Stream GitHub Architecture

The `unified_codebase_analyzer.py` splits GitHub repositories into three independent streams:

**Stream 1: Code Analysis** (C3.x features)
- Deep AST parsing (9 languages)
- Design pattern detection (C3.1)
- Test example extraction (C3.2)
- How-to guide generation (C3.3)
- Configuration extraction (C3.4)
- Architectural overview (C3.5)
- API reference + dependency graphs

**Stream 2: Documentation**
- README, CONTRIBUTING, LICENSE
- docs/ directory markdown files
- Wiki pages (if available)
- CHANGELOG and version history

**Stream 3: Community Insights**
- GitHub metadata (stars, forks, watchers)
- Issue analysis (top problems and solutions)
- PR trends and contributor stats
- Release history
- Label-based topic detection

**Key Benefits:**
- Unified interface for GitHub URLs and local paths
- Analysis depth control: 'basic' (1-2 min) or 'c3x' (20-60 min)
- Enhanced router generation with GitHub context
- Smart keyword extraction weighted by GitHub labels (2x weight)
- 81 E2E tests passing (0.44 seconds)

## 🔧 Helper Scripts

The `scripts/` directory contains utility scripts:

```bash
# Bootstrap skill generation - self-hosting skill-seekers as a Claude skill
./scripts/bootstrap_skill.sh

# Start MCP server for HTTP transport
./scripts/start_mcp_server.sh

# Script templates are in scripts/skill_header.md
```

**Bootstrap Skill Workflow:**
1. Analyzes skill-seekers codebase itself (dogfooding)
2. Combines handcrafted header with auto-generated analysis
3. Validates SKILL.md structure
4. Outputs ready-to-use skill for Claude Code

## 🔍 Performance Characteristics

| Operation | Time | Notes |
|-----------|------|-------|
| Scraping (sync) | 15-45 min | First time, thread-based |
| Scraping (async) | 5-15 min | 2-3x faster with `--async` |
| Building | 1-3 min | Fast rebuild from cache |
| Re-building | <1 min | With `--skip-scrape` |
| Enhancement (LOCAL) | 30-60 sec | Uses Claude Code Max |
| Enhancement (API) | 20-40 sec | Requires API key |
| Packaging | 5-10 sec | Final .zip creation |

## 🎉 Recent Achievements

**v3.1.4 (Unreleased) - "Selector Fallback & Dry-Run Fix":**
- 🐛 **Issue #300: `create https://reactflow.dev/` only found 1 page** — Now finds 20+ pages
- 🔧 **Centralized selector fallback** — `FALLBACK_MAIN_SELECTORS` constant + `_find_main_content()` helper replace 3 duplicated fallback loops
- 🔗 **Link extraction before early return** — `extract_content()` now discovers links even when no content selector matches
- 🔍 **Dry-run full-page link discovery** — Both sync and async dry-run paths extract links from the full page (was main-content-only or missing entirely)
- 🛣️ **Smart `create --config` routing** — Peeks at JSON to route `base_url` configs to doc_scraper and `sources` configs to unified_scraper
- 🧹 **Removed `body` fallback** — `body` matched everything, hiding real selector failures
- ✅ **Pre-existing test fixes** — `test_auto_fetch_enabled` (react.json exists locally) and `test_mcp_validate_legacy_config` (react.json is now unified format)

**v3.1.3 (Released) - "Unified Argument Interface":**
- 🔧 **Unified Scraper Arguments** - All scrapers (scrape, github, analyze, pdf) now share a common argument contract via `add_all_standard_arguments(parser)` in `arguments/common.py`
- 🐛 **Fix `create` Argument Forwarding** - `create <url> --dry-run`, `create owner/repo --dry-run`, `create ./path --dry-run` all work now (previously crashed)
- 🏗️ **Argument Deduplication** - Removed duplicated arg definitions from github.py, scrape.py, analyze.py, pdf.py; all import shared args
- ➕ **New Flags** - GitHub and PDF scrapers gain `--dry-run`, `--verbose`, `--quiet`; analyze gains `--name`, `--description`, `--quiet`
- 🔀 **Route-Specific Forwarding** - `create` command's `_add_common_args()` now only forwards universal flags; route-specific flags moved to their respective methods
