Work Session Summary - March 25, 2026

Task: Complete OpenAPI/Swagger Documentation

Status: ✅ COMPLETED

Work Completed

1. Interactive Swagger UI Implementation ✅

Created a modern, interactive API documentation interface using Swagger UI 5.9.0.

Files Created: - docs/swagger-ui.html - Interactive documentation page

Features: - Beautiful UI with brand colors (purple gradient) - Interactive "Try it out" functionality - Syntax highlighting (Monokai theme) - Deep linking support - Request duration display - Authorization persistence - Comprehensive endpoint documentation

2. HTTP Documentation Endpoints ✅

Extended the health check server to serve documentation endpoints.

Files Modified: - relay-server/health_check.py

New Endpoints: - GET /docs - Serve Swagger UI HTML - GET /openapi.yaml - Serve OpenAPI specification

3. OpenAPI Specification Updates ✅

Updated the OpenAPI 3.0.3 specification to include new endpoints and documentation links.

Files Modified: - docs/openapi.yaml

Updates: - Added /docs endpoint documentation - Added /openapi.yaml endpoint documentation - Enhanced description with documentation links - Added code examples reference

4. Comprehensive Code Examples ✅

Created detailed code examples in 6 programming languages.

Files Created: - docs/CODE_EXAMPLES.md (~1,200 lines)

Languages Covered: - JavaScript/TypeScript - Python - Go - Java - C# - Rust

Examples Include: - Basic WebSocket connection - Authentication flow - Session management - Command sending - Error handling - Best practices

5. Bug Fix - Circular Import Issue ✅

Resolved circular import conflict with Python's ssl module.

Files Changed: - relay-server/ssl.py → relay-server/ssl_manager.py (renamed) - scripts/manage_ssl.py (updated imports)

Issue: File named ssl.py conflicted with Python's standard library ssl module Solution: Renamed to ssl_manager.py and updated all references

6. Documentation Updates ✅

Updated project documentation to reflect new features.

Files Modified: - AGENTS.md - docs/README.md

Updates: - Added health check server startup instructions - Updated testing documentation - Added new documentation endpoint references - Enhanced API documentation section

Format: OpenAPI 3.0.3 in YAML

Code Examples

Access: docs/CODE_EXAMPLES.md

Languages: JavaScript, Python, Go, Java, C#, Rust

How to Use

Start Health Check Server

cd relay-server
python3 health_check.py

Output: 

🏥 Health Check Server starting on port 8000
   Health endpoint:   http://localhost:8000/health
   Metrics endpoint:  http://localhost:8000/metrics
   Status endpoint:   http://localhost:8000/status
   API Docs:          http://localhost:8000/docs
   OpenAPI Spec:      http://localhost:8000/openapi.yaml

Access Documentation

In Browser: 1. Navigate to: http://localhost:8000/docs 2. Explore endpoints interactively 3. Use "Try it out" to test HTTP endpoints 4. View code examples in CODE_EXAMPLES.md

Programmatic: 

# Get OpenAPI spec
curl http://localhost:8000/openapi.yaml

# Get health status
curl http://localhost:8000/health
