   - Runs `swag init` on backend code
   - Output: `openapi/go-api.json`

3. `generate-openapi-from-server.sh` (executable)
   - Fetches OpenAPI specs from running servers
   - Alternative to source-based generation
   - No dependency requirements
   - Outputs: `openapi/python-api.json`, `openapi/go-api.json`

4. `generate-typescript-types.sh` (executable)
   - Generates TypeScript types from OpenAPI specs
   - Uses `openapi-typescript` package

5. `generate-python-client.sh` (executable)
   - Generates Python API clients from OpenAPI specs
   - Uses `openapi-python-client` package
   - Outputs: `src/tracertm/generated/python_api_client/`, `src/tracertm/generated/go_api_client/`

6. `generate-all-api-contracts.sh` (executable)
   - Runs all generation steps in order
   - Unified script for complete API contract generation
   - Calls all other generation scripts
