+```
+
+### Mode Detection
+
+The server operates in two modes based on environment variables:
+
+**Project Mode** (Single Project):
+- When `WIKIJS_PROJECT` is set
+- Operates on single project path
+- Used by `projman` plugin
+- Pages scoped to `/base_path/project/`
+
+**Company Mode** (Multi-Project / PMO):
+- When `WIKIJS_PROJECT` is NOT set
+- Operates on all projects in organization
+- Used by `projman-pmo` plugin
+- Pages scoped to `/base_path/`
+
+### GraphQL Integration
+
+The server uses Wiki.js GraphQL API for all operations:
+- **Pages API**: Create, read, update, list, search pages
+- **Tags**: Categorize and filter content
+- **Search**: Full-text search with tag filtering
+- **Lessons Learned**: Specialized workflow for sprint insights
+
+## Installation
+
+### Prerequisites
+
+- Python 3.10 or higher
+- Access to Wiki.js instance with API token
+- GraphQL API enabled on Wiki.js
+
+### Step 1: Install Dependencies
+
+```bash
+cd mcp-servers/wikijs
+python3 -m venv .venv
+source .venv/bin/activate  # Linux/Mac
+# or .venv\Scripts\activate  # Windows
+
+pip install -r requirements.txt
+```
+
+### Step 2: System Configuration
+
+Create system-level configuration with credentials:
+
+```bash
+mkdir -p ~/.config/claude
+
+cat > ~/.config/claude/wikijs.env << 'EOF'
+# Wiki.js API Configuration
+WIKIJS_API_URL=http://wikijs.hotport/graphql
+WIKIJS_API_TOKEN=your_api_token_here
+WIKIJS_BASE_PATH=/hyper-hive-labs
+EOF
+
+chmod 600 ~/.config/claude/wikijs.env
+```
+
+**Obtaining Wiki.js API Token:**
+1. Log in to Wiki.js as administrator
+2. Navigate to Administration → API Access
+3. Click "New API Key"
+4. Set permissions: Pages (read/write), Search (read)
+5. Copy the generated JWT token
+
+### Step 3: Project Configuration (Optional)
+
+For project-scoped operations, create `.env` in project root:
+
+```bash
+# In your project directory
+cat > .env << 'EOF'
+# Wiki.js project path
+WIKIJS_PROJECT=projects/cuisineflow
+EOF
+
+# Add to .gitignore
+echo ".env" >> .gitignore
+```
+
+**Note:** Omit `.env` for company-wide (PMO) mode.
+
+## Usage
+
+### Running the MCP Server
+
+```bash
+cd mcp-servers/wikijs
+source .venv/bin/activate
+python -m mcp_server.server
+```
+
+The server runs as a stdio-based MCP server and communicates via JSON-RPC 2.0.
+
+### Integration with Claude Code
+
+The MCP server is referenced in plugin `.mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "wikijs": {
+      "command": "python",
+      "args": ["-m", "mcp_server.server"],
+      "cwd": "${CLAUDE_PLUGIN_ROOT}/../mcp-servers/wikijs",
+      "env": {}
+    }
+  }
+}
+```
+
+### Example Tool Calls
+
+**Search Pages:**
+```json
+{
+  "name": "search_pages",
+  "arguments": {
+    "query": "API documentation",
+    "tags": "backend,api",
+    "limit": 10
+  }
+}
+```
+
+**Create Lesson Learned:**
+```json
+{
+  "name": "create_lesson",
+  "arguments": {
+    "title": "Sprint 16 - Prevent Claude Code Infinite Loops",
+    "content": "## Problem\\n\\nClaude Code entered infinite loop...\\n\\n## Solution\\n\\n...",
+    "tags": "claude-code,testing,validation",
+    "category": "sprints"
+  }
+}
+```
+
+**Search Lessons:**
+```json
+{
+  "name": "search_lessons",
+  "arguments": {
+    "query": "validation",
+    "tags": "testing,claude-code",
+    "limit": 20
+  }
+}
+```

+
+### Lessons Learned Categories
+
+- **sprints/**: Sprint-specific lessons and retrospectives
+- **patterns/**: Recurring patterns and solutions
+- **architecture/**: Architectural decisions and outcomes
+- **tools/**: Tool-specific tips and gotchas
+
+## Testing
+
+See [TESTING.md](./TESTING.md) for comprehensive testing instructions.
+
+**Quick Test:**
+```bash
+source .venv/bin/activate
+pytest -v
+```
+
+**Test Coverage:**
+- 18 tests covering all major functionality
+- Mock-based unit tests (fast)
+- Integration tests with real Wiki.js instance
+- Configuration validation
+- Mode detection
+- Error handling
+
+## Lessons Learned System
+
+### Why This Matters
+
+After 15 sprints without systematic lesson capture, repeated mistakes occurred:
+- Claude Code infinite loops on similar issues: 2-3 times
+- Same architectural mistakes: Multiple occurrences
+- Forgotten optimizations: Re-discovered each time
+
+**Solution:** Mandatory lessons learned capture at sprint close, searchable at sprint start.
+
+### Workflow
+
+**Sprint Close (Orchestrator):**
+1. Capture what went wrong
+2. Document what went right
+3. Note preventable repetitions
+4. Tag for discoverability
+
+**Sprint Start (Planner):**
+1. Search relevant lessons by tags/keywords
+2. Review applicable patterns
+3. Apply preventive measures
+4. Avoid known pitfalls
+
+### Lesson Structure
+
+```markdown
+# Sprint X - [Lesson Title]
+
+## Context
+[What were you trying to do?]
+
+## Problem
+[What went wrong or what insight emerged?]
+
+## Solution
+[How did you solve it?]
+
+## Prevention
+[How can this be avoided or optimized in the future?]
+
+## Tags
+[Comma-separated tags for search]
+```
+
+## Troubleshooting
+
+### Connection Errors
+
+**Error:** `Failed to connect to Wiki.js GraphQL endpoint`
+
+**Solutions:**
+- Verify `WIKIJS_API_URL` is correct and includes `/graphql`
+- Check Wiki.js is running and accessible
+- Ensure GraphQL API is enabled in Wiki.js admin settings
+
+### Authentication Errors
+
+**Error:** `Unauthorized` or `Invalid token`
+
+**Solutions:**
+- Verify API token is correct and not expired
+- Check token has required permissions (Pages: read/write, Search: read)
+- Regenerate token in Wiki.js admin if needed
+
+### Permission Errors
+
+**Error:** `Page creation failed: Permission denied`
+
+**Solutions:**
+- Verify API key has write permissions
+- Check user/group permissions in Wiki.js
+- Ensure base path exists and is accessible
+
+### Mode Detection Issues
+
+**Error:** Operating in wrong mode
+
+**Solutions:**
+- Check `WIKIJS_PROJECT` environment variable
+- Clear project `.env` for company mode
+- Verify configuration loading order (project overrides system)
+
+## Security Considerations
+
+1. **Never commit tokens**: Keep `~/.config/claude/wikijs.env` and `.env` out of git
+2. **Token scope**: Use minimum required permissions (Pages + Search)
+3. **Token rotation**: Regenerate tokens periodically
+4. **Access control**: Use Wiki.js groups/permissions for sensitive docs
+5. **Audit logs**: Review Wiki.js audit logs for unexpected operations
+
+## Performance
+
+- **GraphQL queries**: Optimized for minimal data transfer
+- **Search**: Indexed by Wiki.js for fast results
+- **Pagination**: Configurable result limits (default: 20)
+- **Caching**: Wiki.js handles internal caching
+
+## Development
+

+
+```bash
+# All tests
+pytest -v
+
+# Specific test file
+pytest tests/test_config.py -v

+```bash
+# Mark tests for integration
+pytest -v -m integration
+
+# Run specific integration test
+pytest tests/test_wikijs_client.py::test_create_page -v -m integration
+```
+
+### Integration Test Scenarios
+
+**Scenario 1: Page Lifecycle**
+1. Create page with `create_page`
+2. Retrieve with `get_page`
+3. Update with `update_page`
+4. Search for page with `search_pages`
+5. Cleanup (manual via Wiki.js UI)
+
+**Scenario 2: Lessons Learned Workflow**
+1. Create lesson with `create_lesson`
+2. Search lessons with `search_lessons`
+3. Add tags with `tag_lesson`
+4. Verify searchability
+
+**Scenario 3: Mode Detection**
+1. Test in project mode (with `WIKIJS_PROJECT`)
+2. Test in company mode (without `WIKIJS_PROJECT`)
+3. Verify path scoping
+
+## Manual Testing
+
+### Test 1: Create and Retrieve Page
+
+```bash
+# Start MCP server
+python -m mcp_server.server
+
+# In another terminal, send MCP request
+echo '{
+  "jsonrpc": "2.0",
+  "id": 1,
+  "method": "tools/call",
+  "params": {
+    "name": "create_page",
+    "arguments": {
+      "path": "documentation/test-api",
+      "title": "Test API Documentation",
+      "content": "# Test API\\n\\nThis is a test page.",
+      "tags": "api,testing",
+      "publish": true
+    }
+  }
+}' | python -m mcp_server.server
+```
+
+**Expected Result:**
+```json
+{
+  "success": true,
+  "page": {
+    "id": 123,
+    "path": "/hyper-hive-labs/projects/test-project/documentation/test-api",
+    "title": "Test API Documentation"
+  }
+}
+```
+
+### Test 2: Search Lessons
+
+```bash
+echo '{
+  "jsonrpc": "2.0",
+  "id": 2,
+  "method": "tools/call",
+  "params": {
+    "name": "search_lessons",
+    "arguments": {
+      "query": "validation",
+      "tags": "testing,claude-code",
+      "limit": 10
+    }
+  }
+}' | python -m mcp_server.server
+```
+
+**Expected Result:**
+```json
+{
+  "success": true,
+  "count": 2,
+  "lessons": [...]
+}
+```
+
+### Test 3: Mode Detection
+
+**Project Mode:**
+```bash
+# Create .env with WIKIJS_PROJECT
+echo "WIKIJS_PROJECT=projects/test-project" > .env
+
+# Start server and check logs
+python -m mcp_server.server 2>&1 | grep "mode"
+```
+
+**Expected Log:**
+```
+INFO:Running in project mode: projects/test-project
+```
+
+**Company Mode:**
+```bash
+# Remove .env
+rm .env
+
+# Start server and check logs
+python -m mcp_server.server 2>&1 | grep "mode"
+```
+
+**Expected Log:**
+```
+INFO:Running in company-wide mode (PMO)
+```
+
+## Test Data Management
+
+### Cleanup Test Data
+
+After integration tests, clean up test pages in Wiki.js:
+
+```bash
+# Via Wiki.js UI
+1. Navigate to /test-integration/
+2. Select test pages
+3. Delete
+
+# Or via GraphQL (advanced)
+curl -X POST http://wikijs.hotport/graphql \
+  -H "Authorization: Bearer $WIKIJS_API_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "query": "mutation { pages { delete(id: 123) { responseResult { succeeded } } } }"
+  }'
+```
+
+### Test Data Fixtures
+
+For repeatable testing, create fixtures:
+
+```python
+# tests/conftest.py
+import pytest
+
+@pytest.fixture
+async def test_page():
+    """Create a test page and clean up after"""
+    client = WikiJSClient(...)
+    page = await client.create_page(
+        path="test/fixture-page",
+        title="Test Fixture",
+        content="# Test"
+    )
+    yield page
+    # Cleanup after test
+    await client.delete_page(page['id'])
+```
+
+## Continuous Integration

+```
+
+**Target Coverage:** 90%+ for all modules
+
+## Performance Testing
+
+### Benchmark GraphQL Operations
+
+```python
+import time
+
+async def benchmark_search():
+    client = WikiJSClient(...)
+    start = time.time()
+    results = await client.search_pages("test")
+    elapsed = time.time() - start
+    print(f"Search took {elapsed:.3f}s")
+```
+
+**Expected Performance:**
+- Search: < 500ms
+- Get page: < 200ms
+- Create page: < 1s
+- Update page: < 500ms
+
+## Common Test Failures
+
+### 1. Configuration Not Found
+
+**Error:**
+```
+FileNotFoundError: System config not found: ~/.config/claude/wikijs.env
+```
+
+**Solution:**
+```bash
+mkdir -p ~/.config/claude
+cat > ~/.config/claude/wikijs.env << 'EOF'
+WIKIJS_API_URL=http://wikijs.hotport/graphql
+WIKIJS_API_TOKEN=test_token
+WIKIJS_BASE_PATH=/test
+EOF
+```
+
+### 2. GraphQL Connection Error
+
+**Error:**
+```
+httpx.ConnectError: Connection refused
+```
+
+**Solution:**
+- Verify Wiki.js is running
+- Check `WIKIJS_API_URL` is correct
+- Ensure `/graphql` endpoint is accessible
+
+### 3. Permission Denied
+
+**Error:**
+```
+ValueError: Failed to create page: Permission denied
+```
+
+**Solution:**
+- Regenerate API token with write permissions
+- Check Wiki.js user/group permissions
+- Verify base path exists and is accessible
+
+### 4. Environment Variable Pollution
+
+**Error:**
+```
+AssertionError: assert 'project' == 'company'
+```
+
+**Solution:**
+```python
+# In test, clear environment
+monkeypatch.delenv('WIKIJS_PROJECT', raising=False)
+```
+
+## Best Practices
+
+1. **Isolate Tests**: Each test should be independent
+2. **Mock External Calls**: Use mocks for unit tests
+3. **Clean Up Resources**: Delete test pages after integration tests
+4. **Use Fixtures**: Reuse common setup/teardown
+5. **Test Error Cases**: Not just happy paths
+6. **Document Assumptions**: Comment what tests expect
+7. **Consistent Naming**: Follow `test_<what>_<scenario>` pattern
+
+## Next Steps
+
+After testing passes:
+1. Review code coverage report
+2. Add integration tests for edge cases
+3. Document any new test scenarios
+4. Update CI/CD pipeline
+5. Create test data fixtures for common scenarios
+
+## Support
+
+For testing issues:
+- Check test logs: `pytest -v -s`
+- Review Wiki.js logs
+- Verify configuration files
+- See main README.md troubleshooting section
