Add pascal_to_snake_case utility to deduplicate class-to-module conversion - Add LlamaStackClient wrapper with nested API access (chat.completions.*) - Add x-child-tags documentation showing nested API attributes - Update examples to use LlamaStackClient instead of individual API classes - Improve _create_event_stream for better SSE handling with proper typing Model Template Enhancements: - Enhance anyOf/oneOf deserialization with discriminator support - Add fallback to from_dict for streaming chunks - Use pascal_to_snake_case for consistent module resolution Streaming Improvements: - Add Stream template for server-sent events - Fix return types and parameter passing in _create_event_stream - Add proper decoder for streaming response types This enables the SDK to support both flat (client.chat_completions.create) and hierarchical (client.chat.completions.create) access patterns. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- .../templates/python/__init__package.mustache | 41 +- .../openapi/templates/python/api.mustache | 143 ++++++- .../templates/python/api_client.mustache | 25 +- .../openapi/templates/python/api_doc.mustache | 17 +- .../templates/python/api_doc_example.mustache | 13 +- .../templates/python/exports_package.mustache | 17 + .../openapi/templates/python/lib/_utils.py | 26 ++ .../python/llama_stack_client.mustache | 193 +++++++++ .../templates/python/model_anyof.mustache | 131 +++++- .../templates/python/model_generic.mustache | 118 +++++- .../templates/python/model_oneof.mustache | 373 ++++++++++++++++-- .../openapi/templates/python/stream.mustache | 182 +++++++++ 12 files changed, 1221 insertions(+), 58 deletions(-) create mode 100644 client-sdks/openapi/templates/python/lib/_utils.py create mode 100644 client-sdks/openapi/templates/python/llama_stack_client.mustache create mode 100644 client-sdks/openapi/templates/python/stream.mustache diff --git a/client-sdks/openapi/templates/python/__init__package.mustache b/client-sdks/openapi/templates/python/__init__package.mustache index 73f0adf0d4..07a89713ae 100644 --- a/client-sdks/openapi/templates/python/__init__package.mustache +++ b/client-sdks/openapi/templates/python/__init__package.mustache @@ -4,13 +4,36 @@ {{>partial_header}} +from {{packageName}}._exceptions import ( + BadRequestError, + AuthenticationError, + PermissionDeniedError, + NotFoundError, + ConflictError, + UnprocessableEntityError, + RateLimitError, + InternalServerError) +from {{packageName}}.lib import Agent, AgentEventLogger __version__ = "{{packageVersion}}" # Define package exports __all__ = [ + "Agent", + "AgentEventLogger", + "BadRequestError", + "AuthenticationError", + "PermissionDeniedError", + "NotFoundError", + "ConflictError", + "UnprocessableEntityError", + "RateLimitError", + "InternalServerError", + "LlamaStackClient", + "AsyncLlamaStackClient", {{#apiInfo}}{{#apis}}"{{classname}}", {{/apis}}{{/apiInfo}}"ApiResponse", + "APIResponse", "ApiClient", "Configuration", "OpenApiException", @@ -20,7 +43,19 @@ __all__ = [ "ApiAttributeError", "ApiException", {{#hasHttpSignatureMethods}}"HttpSigningConfiguration", -

The previous implementation used `if value:` which incorrectly filtered out valid falsy values. This caused data loss when serializing models with boolean False, integer 0, empty strings, or empty collections. Changes: - Replace truthiness check with explicit `is None` check - Cache dictionary value in variable to avoid repeated lookups - Preserve all valid values including falsy ones Impact: Models with falsy values will now serialize correctly.

Add RateLimitException for HTTP 429 status codes - Raised automatically when server returns 429 - Allows explicit handling of rate limit errors 2. Add httpx-style property aliases - message property (returns reason) - status_code property (returns status) - Provides compatibility with httpx exception interface 3. Add exception name aliases - BadRequestError, AuthenticationError, PermissionDeniedError, etc. - Maps to existing Exception classes (BadRequestException, etc.) - Allows consistent naming across urllib3 and httpx styles 4. Update package imports - Import from exceptions.py instead of _exceptions.py - Uses urllib3-based exceptions with added compatibility Benefits: - Explicit 429 rate limit error handling - Code compatibility with both naming conventions - Consistent exception interface across HTTP libraries Co-Authored-By: Claude Sonnet 4.5 --- .../templates/python/__init__package.mustache | 2 +- .../templates/python/exceptions.mustache | 29 +++++++++++++++++++ 2 files changed, 30 insertions(+), 1 deletion(-) diff --git a/client-sdks/openapi/templates/python/__init__package.mustache b/client-sdks/openapi/templates/python/__init__package.mustache index 07a89713ae..f01c71fa0a 100644 --- a/client-sdks/openapi/templates/python/__init__package.mustache +++ b/client-sdks/openapi/templates/python/__init__package.mustache @@ -4,7 +4,7 @@ {{>partial_header}} -from {{packageName}}._exceptions import ( +from {{packageName}}.exceptions import ( BadRequestError, AuthenticationError, PermissionDeniedError, diff --git a/client-sdks/openapi/templates/python/exceptions.mustache b/client-sdks/openapi/templates/python/exceptions.mustache index 90de0b38c5..41336cbe15 100644 --- a/client-sdks/openapi/templates/python/exceptions.mustache +++ b/client-sdks/openapi/templates/python/exceptions.mustache @@ -121,6 +121,16 @@ class ApiException(OpenApiException): pass self.headers = http_resp.getheaders() + @property + def message(self) -> Optional[str]: + """Alias for reason to match httpx-style exceptions.""" + return self.reason + + @property + def status_code(self) -> Optional[int]: + """Alias for status to match httpx-style exceptions.""" + return self.status + @classmethod def from_response( cls, @@ -148,6 +158,9 @@ class ApiException(OpenApiException): if http_resp.status == 422: raise UnprocessableEntityException(http_resp=http_resp, body=body, data=data) + if http_resp.status == 429: + raise RateLimitException(http_resp=http_resp, body=body, data=data) + if 500 <= http_resp.status <= 599: raise ServiceException(http_resp=http_resp, body=body, data=data) raise ApiException(http_resp=http_resp, body=body, data=data) @@ -196,6 +209,22 @@ class UnprocessableEntityException(ApiException): pass +class RateLimitException(ApiException): + """Exception for HTTP 429 Rate Limit.""" + pass + + +# Aliases for compatibility with _exceptions.py naming convention +BadRequestError = BadRequestException +AuthenticationError = UnauthorizedException +PermissionDeniedError = ForbiddenException +NotFoundError = NotFoundException +ConflictError = ConflictException +UnprocessableEntityError = UnprocessableEntityException +RateLimitError = RateLimitException +InternalServerError = ServiceException + + def render_path(path_to_item): """Returns a string representation of a path""" result = "" From db88535f862d851ea6062f08eec050a317128972 Mon Sep 17 00:00:00 2001 From: Eitan Geiger Date: Mon, 12 Jan 2026 15:36:55 +0200 Subject: [PATCH 09/10] tests: remove invalid BadRequestException references Remove BadRequestException from exception handling tuples in vector store tests.
