-# CI/CD Workflow Architecture
-
-## 🗺️ Overview
-
-The dance-lessons-coach project uses a **multi-workflow architecture** for better separation of concerns, maintainability, and flexibility.
-
-## 📁 Workflow Files
-
-### 1. `ci-cd.yaml` - Main CI/CD Pipeline
-
-**Purpose**: Run tests, build binaries, and generate documentation
-
-**Triggers**:
-- Push to `main`, `ci/**`, `feature/**`, `fix/**`, `refactor/**` branches
-- Pull requests to `main` branch
-- Manual workflow dispatch
-
-**Jobs**:
-1. **build-cache** - Build and cache Docker build environment
-2. **ci-pipeline** - Run tests, build binaries, generate Swagger docs
-3. **trigger-docker-push** - Trigger separate Docker workflow on main branch
-
-**Key Features**:
-- Runs in container environment with all build tools
-- Generates Swagger documentation
-- Runs BDD and unit tests with PostgreSQL
-- Updates badges and version information
-- Triggers Docker workflow only on main branch
-
-### 2. `docker-push.yaml` - Docker Image Publishing
-
-**Purpose**: Build and push Docker images to registry
-
-**Triggers**:
-- Manual workflow dispatch only (no automatic triggers)
-- Triggered by `ci-cd.yaml` on main branch
-
-**Jobs**:
-1. **docker-push** - Build production Docker image and push to registry
-
-**Key Features**:
-- Runs on host environment (access to Docker daemon)
-- Uses dependency hash from build-cache
-- Builds minimal Alpine-based production image
-- Pushes multiple tags (version, latest, commit SHA)
-
-## 🔧 Architecture Benefits
-
-### 1. Clear Separation of Concerns
-- **CI/CD Pipeline**: Testing and artifact generation
-- **Docker Publishing**: Image building and registry operations
-
-### 2. Proper Environment Isolation
-- **CI jobs run in container**: Consistent build environment
-- **Docker jobs run on host**: Access to Docker daemon
-
-### 3. Flexible Testing
-- Can trigger Docker workflow independently for testing
-- No complex conditional logic in main workflow
-- Easier to debug and maintain
-
-### 4. Better Security
-- Docker operations isolated in separate workflow
-- Clear dependency between test success and deployment
-- Manual trigger capability for emergency situations
-
-## 🚀 Usage Examples
-
-### Trigger Full CI/CD Pipeline
-```bash
-# Automatically triggered on push to main branch
-# Or manually:
-./scripts/gitea-client.sh trigger-workflow arcodange dance-lessons-coach ci-cd.yaml main
-```
-
-### Trigger Docker Push Manually
-```bash
-# Get dependency hash from build-cache job first
-DEPS_HASH="abc123def456"
-
-# Trigger Docker workflow manually
-./scripts/gitea-client.sh trigger-workflow arcodange dance-lessons-coach docker-push.yaml main --deps_hash $DEPS_HASH
-```
-
-### Workflow Dispatch Parameters (docker-push.yaml)
-- `deps_hash` (required): Dependency hash from build-cache job
-- `ref` (optional): Git reference (branch/tag), defaults to current
-
-## 🔗 Workflow Dependencies
-
-```mermaid
-graph TD
-    A[Push to main] --> B[ci-cd.yaml]
-    B --> C[build-cache job]
-    B --> D[ci-pipeline job]
-    D --> E[trigger-docker-push job]
-    E --> F[docker-push.yaml]
-    F --> G[docker-push job]
-    G --> H[Docker Registry]
-```
-
-## 📋 Best Practices
-
-### 1. Always Run CI First
-- Docker workflow should only be triggered after CI passes
-- Maintains quality gate before deployment
-
-### 2. Use Dependency Hash
-- Ensures consistent builds across workflows
-- Pass hash from build-cache to docker-push
-
-### 3. Manual Testing
-- Use separate Docker workflow for testing image builds
-- Avoids polluting main branch with test images
-
-### 4. Monitor Both Workflows
-- CI/CD workflow for test results and artifacts
-- Docker workflow for image build and push status
-
-## 🎯 Docker Build Strategy Decision
-
-### 🏆 Chosen Approach: Attempt 2 (Standard Dockerfile)
-
-After extensive testing of multiple approaches, we selected **Attempt 2** as the optimal Docker build strategy.
-
-#### ⚡ Why Attempt 2 Won:
-
-**1. Simplicity (60% smaller workflow)**
-- 73 lines vs 158 lines in complex approaches
-- No inline Dockerfile generation
-- Standard `docker build -f docker/Dockerfile .` command
-
-**2. Better Performance**
-- No artifact/cache action overhead
-- Natural Docker layer caching works optimally
-- Faster execution without complex variable substitutions
-
-**3. Superior Reliability**
-- Proven standard Docker build process
-- Easier to debug and maintain
-- Fewer moving parts = fewer failures
-
-**4. Better Maintainability**
-- Uses standard Dockerfile (easier to understand)
-- No complex YAML templating
-- Clear separation of concerns
-
-#### 🗑️ Why We Rejected Other Approaches:
-
-**Attempt 1 (Inline Dockerfile):**
-- Complex YAML templating
-- Harder to debug and maintain
-- No significant performance benefit
-
-**Attempt 3 (Build Cache Image):**
-- Added complexity with cache management
-- Slower due to artifact actions overhead
-- More prone to cache invalidation issues
-
-**Attempt 4 (Template File):**
-- Added unnecessary file management
-- No clear advantage over standard Dockerfile
-- More complex workflow
-
-### 📊 Performance Comparison:
-
-| Approach | Lines of Code | Complexity | Reliability | Maintainability |
-|----------|---------------|------------|-------------|-----------------|
-| **Attempt 2** | 73 | Low | High | Excellent |
-| Attempt 1 | 158 | High | Medium | Poor |
-| Attempt 3 | 125 | Medium | Medium | Fair |
-| Attempt 4 | 110 | Medium | High | Good |
-
-### 🔧 Implementation Details:
-
-**Standard Dockerfile Approach:**
-```yaml
-- name: Build and push Docker image
-  run: |
-    docker build -t dance-lessons-coach -f docker/Dockerfile .
-    docker tag dance-lessons-coach "$IMAGE_NAME"
-    docker push "$IMAGE_NAME"
-```
-
-**Key Benefits:**
-- Uses multi-stage builds for optimization
-- Standard Docker layer caching works naturally
-- Easy to understand and modify
-- Proven reliability in production
-
-## 🎯 Future Enhancements
-
-### Potential Improvements:
-- Add workflow status badges to README
-- Implement workflow chaining with outputs
-- Add matrix builds for multiple architectures
-- Implement canary deployment workflow
-- Add rollback capability
-
-### Architecture Considerations:
-- Keep workflows focused on single responsibilities
-- Maintain clear separation between test and deploy
-- Document all workflow triggers and conditions
-- Monitor workflow execution times and optimize
-
-## 📝 Maintenance
-
-### Adding New Jobs:
-- Add to appropriate workflow based on responsibility
-- CI-related jobs → `ci-cd.yaml`
-- Docker-related jobs → `docker-push.yaml`
-
-### Modifying Triggers:
-- Update trigger conditions in respective workflow files
-- Test changes thoroughly before merging
-
-### Debugging:
-- Check workflow logs in Gitea Actions
-- Use `gitea-client.sh diagnose-job` for detailed analysis
-- Monitor workflow dependencies and execution order
-
-## 🔒 Security
-
-### Secrets Management:
-- Docker registry credentials stored in Gitea secrets
-- Never hardcode credentials in workflow files
-- Use GitHub token for workflow dispatch
-
-### Access Control:
-- Only authorized users can trigger workflows
-- Manual approval required for production deployments
-- Audit logs available for all workflow executions
-
-This architecture provides a clean, maintainable, and secure CI/CD pipeline that scales well with project growth while maintaining clear separation of concerns.

 ```
 
+## CI/CD Pipeline
+
+dance-lessons-coach features an optimized CI/CD pipeline using GitHub Actions with container/services architecture:
+
+### Key Features
+- ✅ **Container-based execution**: All steps run in pre-built Docker cache images
+- ✅ **Service-based PostgreSQL**: Automatic database service provisioning
+- ✅ **Smart caching**: Dependency-aware cache invalidation
+- ✅ **Multi-platform**: Compatible with Gitea, GitHub, and GitLab
+- ✅ **Fast execution**: No Docker Compose overhead
+- ✅ **Reliable testing**: Full database connectivity with proper environment setup
+
+### Architecture
+
+The pipeline uses GitHub Actions' native `container` and `services` directives instead of Docker Compose:
+
+```yaml
+jobs:
+  ci-pipeline:
+    container:
+      image: gitea.arcodange.lab/arcodange/dance-lessons-coach-build-cache:${{ needs.build-cache.outputs.deps_hash }}
+    
+    services:
+      postgres:
+        image: postgres:15
+        env:
+          POSTGRES_USER: postgres
+          POSTGRES_PASSWORD: postgres
+          POSTGRES_DB: dance_lessons_coach_bdd_test
+```
+
+### Benefits
+
+1. **Performance**: Direct container execution without compose overhead
+2. **Reliability**: Service containers managed by GitHub Actions
+3. **Simplicity**: Cleaner workflow definition
+4. **Portability**: Works across CI platforms
+5. **Caching**: Intelligent dependency-based cache rebuilding
+
+### Workflow Steps
+
+1. **Build Cache**: Creates Docker image with Go tools and dependencies
+2. **CI Pipeline**: Runs tests, builds binaries, and generates documentation
+3. **Database Tests**: Connects to PostgreSQL service container
+4. **Coverage Reporting**: Updates coverage badges automatically
+5. **Artifact Publishing**: Builds and pushes Docker images (main branch only)
+
+### Environment Configuration
+
+The pipeline automatically sets up database environment variables:
+
 ```bash
-curl http://localhost:8080/api/health
-curl http://localhost:8080/api/v1/greet/Alice
+echo "DLC_DATABASE_HOST=postgres" >> $GITHUB_ENV
+echo "DLC_DATABASE_PORT=5432" >> $GITHUB_ENV
+echo "DLC_DATABASE_USER=postgres" >> $GITHUB_ENV
+echo "DLC_DATABASE_PASSWORD=postgres" >> $GITHUB_ENV
+echo "DLC_DATABASE_NAME=dance_lessons_coach_bdd_test" >> $GITHUB_ENV
+echo "DLC_DATABASE_SSL_MODE=disable" >> $GITHUB_ENV
 ```

+```
+
+## Development
+
+### Generate OpenAPI Documentation
+
+The project uses [swaggo/swag](https://github.com/swaggo/swag) to generate OpenAPI/Swagger documentation from code annotations:
+
+```bash
+# Generate documentation
+go generate ./pkg/server/
+
+# This creates:
+# - pkg/server/docs/docs.go (swagger template)
+# - pkg/server/docs/swagger.json (OpenAPI spec)
+# - pkg/server/docs/swagger.yaml (YAML version)
+```
+
+**Note:** `pkg/server/docs/` is gitignored. Documentation is embedded in the binary at build time.
+
+### Documentation Annotations
+
+Add swagger annotations to handlers and models:
+
+```go
+// @Summary Get personalized greeting
+// @Description Returns a greeting with the specified name
+// @Tags greet
+// @Accept json
+// @Produce json
+// @Param name path string true "Name to greet"
+// @Success 200 {object} GreetResponse "Successful response"
+// @Failure 400 {object} ErrorResponse "Invalid name parameter"
+// @Router /v1/greet/{name} [get]
+func (h *apiV1GreetHandler) handleGreetPath(w http.ResponseWriter, r *http.Request) {
+    // handler implementation
+}
+```
+
+## Architecture
+
+This project uses Architecture Decision Records (ADRs) to document key technical choices. See [adr/](adr/) for complete documentation including decisions on Go 1.26.1, Chi router, Zerolog, OpenTelemetry, interface-based design, graceful shutdown, configuration management, testing strategies, and OpenAPI documentation.
+
+**Adding new decisions?** See [adr/README.md](adr/README.md) for guidelines.
+
+## Gitea Integration
+
+dance-lessons-coach includes AI agent skills for Gitea integration to monitor CI/CD jobs and interact with pull requests.
+
+### Gitea Client Skill Setup
+
+The Gitea client skill enables AI agents to:
+- Monitor CI/CD job status
+- Fetch job logs for debugging
+- Comment on pull requests
+- Track PR status
+
+**Setup Instructions:**
+
+1. **Create a Personal Access Token:**
+   - Log in to https://gitea.arcodange.lab
+   - Go to Profile → Settings → Applications
+   - Generate token with `read:repository`, `write:repository`, and `read:user` scopes
+
+2. **Configure Authentication:**
+   ```bash
+   # Option 1: Environment variable
+   export GITEA_API_TOKEN="your_token"
+   
+   # Option 2: Token file (recommended)
    echo "your_token" > ~/.gitea_token
    chmod 600 ~/.gitea_token
    export GITEA_API_TOKEN_FILE="$HOME/.gitea_token"
    ```
 
-Get a token at https://gitea.arcodange.lab → Profile → Settings → Applications.
+3. **Add to shell configuration:**
+   ```bash
+   echo 'export GITEA_API_TOKEN_FILE="$HOME/.gitea_token"' >> ~/.bashrc
+   source ~/.bashrc
+   ```
 
-## Architecture
+**Usage Examples:**
+```bash
+# List recent jobs
+.vibe/skills/gitea-client/scripts/gitea-client.sh list-jobs owner repo workflow_id 5
 
-Key decisions are documented in [adr/](adr/). See [AGENTS.md](AGENTS.md) for the full development reference (commands, config, ADR index, commit conventions).
+# Wait for job completion
+.vibe/skills/gitea-client/scripts/gitea-client.sh wait-job owner repo job_id 300
+
+# Comment on PR
+.vibe/skills/gitea-client/scripts/gitea-client.sh comment-pr owner repo 42 "Build completed!"
+```
+
+**Documentation:** See [.vibe/skills/gitea-client/README.md](.vibe/skills/gitea-client/README.md) for complete setup and usage guide.

 ## What is an ADR?
 
-An ADR is a document capturing one significant architectural decision: the **context** that motivated it, the **decision** itself, and its **consequences**. ADRs are append-only — once published, an ADR is not edited (except for typo / status updates). New decisions that supersede previous ones are recorded as new ADRs that explicitly link back.
+An ADR is a document that captures an important architectural decision made along with its context and consequences.
 
-## Canonical Format
+## Format
 
-All ADRs follow the canonical format below (homogenized 2026-05-03):
+Each ADR follows this structure:
 
 ```markdown
-# NN. Short title summarising the decision
+# [Short title is a few words]
 
-**Status:** <Proposed | Accepted | Implemented | Partially Implemented | Approved | Rejected | Deferred | Deprecated | Superseded by ADR-NNNN>
