-## Key Components -- **process_response.py**: Handles parsing and converting LLM outputs to Pydantic models -- **patch.py**: Contains the core patching logic for modifying provider clients -- **function_calls.py**: Handles generating function/tool schemas from Pydantic models -- **hooks.py**: Provides event hooks for intercepting various stages of the LLM request/response cycle -- **dsl/**: Domain-specific language extensions for specialized model types -- **retry.py**: Implements retry logic for handling validation failures -- **validators.py**: Custom validation mechanisms for structured outputs - -## Testing Guidelines -- Tests are organized by provider under `tests/llm/` -- Each provider has its own conftest.py with fixtures -- Standard tests cover: basic extraction, streaming, validation, retries -- Evaluation tests in `tests/llm/test_provider/evals/` assess model capabilities -- Use parametrized tests when testing similar functionality across variants -- **IMPORTANT**: No mocking in tests - tests make real API calls - -## Documentation Guidelines -- Every provider needs documentation in `docs/integrations/` following standard format -- Provider docs should include: installation, basic example, modes supported, special features -- When adding a new provider, update `mkdocs.yml` navigation and redirects -- Example code should include complete imports and environment setup -- Tutorials should progress from simple to complex concepts -- New features should include conceptual explanation in `docs/concepts/` -- **Writing Style**: Grade 10 reading level, all examples must be working code -

-### Type Checking with ty -- **Type Checker**: Using `ty` for fast, incremental type checking -- **Python Version**: 3.9+ for compatibility -- **Configuration**: Uses `pyproject.toml` settings for type checking -- Run `uv run ty check` before committing - aim for zero errors - -### Code Quality Checks Before Committing -Always run these checks before committing code: -1. **Ruff linting**: `uv run ruff check .` - Fix all errors -2. **Ruff formatting**: `uv run ruff format .` - Apply consistent formatting -3. **Type checking**: `uv run ty check` - Aim for zero type errors -4. **Tests**: Run relevant tests to ensure changes don't break functionality - -### Type Patterns -- **Bounded TypeVars**: Use `T = TypeVar("T", bound=Union[BaseModel, ...])` for constraints -- **Version Compatibility**: Handle Python 3.9 vs 3.10+ typing differences explicitly -- **Union Type Syntax**: Use `from __future__ import annotations` to enable Python 3.10+ union syntax (`|`) in Python 3.9 -- **Simple Type Detection**: Special handling for `list[Union[int, str]]` patterns -- **Runtime Type Handling**: Graceful fallbacks for compatibility - -### Pydantic Integration -- Heavy use of `BaseModel` for structured outputs -- `TypeAdapter` used internally for JSON schema generation -- Field validators and custom types -- Models serve dual purpose: validation and documentation -

These modules are the remaining V1 surface area + to migrate or deprecate as providers move to v2. + +2. **Identify key components**: + - What modes does your provider support? + - What's the main API function being patched? (e.g., `client.chat`, `client.messages.create`) + - How does request preparation work? (converting `response_model` to provider format) + - How does response parsing work? (extracting structured data from raw response) + - How does reask/retry work? (handling validation failures) + +3. **Example V1 structure** (from `instructor/core/client.py`): + +```python +# V1: Factory normalizes mode + applies patching +def from_openai(client, mode=Mode.TOOLS, **kwargs): + _ensure_registry_loaded() + normalized_mode = normalize_mode_for_provider(mode, Provider.OPENAI) + + # Uses instructor.patch() which delegates to the registry handlers + return Instructor( + client=client, + create=instructor.patch( + create=client.chat.completions.create, + mode=normalized_mode, + ), + provider=Provider.OPENAI, + mode=normalized_mode, + **kwargs, + ) +``` + +#### Step 2: Create V2 Provider Directory Structure + +Create the v2 provider directory: + +```bash +mkdir -p instructor/v2/providers/your_provider +touch instructor/v2/providers/your_provider/__init__.py +touch instructor/v2/providers/your_provider/client.py +touch instructor/v2/providers/your_provider/handlers.py +``` + +#### Step 3: Map V1 Modes to V2 Modes + +Determine which generic v2 modes your provider supports: + +- `Mode.TOOLS` - Function calling / tool use +- `Mode.JSON` - JSON mode with schema instructions +- `Mode.JSON_SCHEMA` - Native structured outputs (if supported) +- `Mode.PARALLEL_TOOLS` - Parallel tool calling (if supported) +Provider-specific legacy modes are deprecated in v2. They emit warnings and normalize to generic modes. Use the generic modes directly. + +#### Step 4: Extract Handler Logic from V1 + +Identify the three handler methods needed: + +1. **Request Preparation** (`prepare_request`): + - Look for functions like `handle_cohere_modes()`, `handle_anthropic_json()` + - These convert `response_model` to provider-specific format + - Modify request kwargs (e.g., add `tools` parameter) + +2. **Response Parsing** (`parse_response`): + - Look for functions in v1 utils or response parsers used by the registry + - Extract structured data from raw API response + - Validate against `response_model` using Pydantic + +3. **Reask Handling** (`handle_reask`): + - Look for functions like `reask_cohere_tools()`, `reask_anthropic_json()` + - Modify kwargs to include error context for retry + +**Example V1 handler functions** (from `instructor/processing/function_calls.py` +and `instructor/processing/response.py`): + +```python +# V1: Response parsing helpers on ResponseSchema +@classmethod +def parse_cohere_json_schema(cls, completion, validation_context=None, strict=None): + text = completion.text + return cls.model_validate_json(text, context=validation_context, strict=strict) + +def handle_reask_kwargs(kwargs, mode, response, exception, provider=Provider.OPENAI): + # Dispatch to provider-specific reask handler for retries + return handlers.reask_handler(kwargs, response, exception) +``` + +#### Step 5: Implement V2 Handlers + +Create handler classes using the `@register_mode_handler` decorator: + +```python +# instructor/v2/providers/your_provider/handlers.py +from instructor.v2.core.handler import ModeHandler +from instructor.v2.core.decorators import register_mode_handler +from instructor import Provider, Mode +from pydantic import BaseModel +from typing import Any + +@register_mode_handler(Provider.COHERE, Mode.TOOLS) +class CohereToolsHandler(ModeHandler): + """Handler for Cohere TOOLS mode.""" + + def prepare_request( + self, + response_model: type[BaseModel] | None, + kwargs: dict[str, Any], + ) -> tuple[type[BaseModel] | None, dict[str, Any]]: + """Convert response_model to Cohere tools format.""" + if response_model is None: + return None, kwargs + + #

v2 during migration +- Use `instructor.from_provider()` which routes to v2 when available +- Test both sync and async clients +- Verify all modes work correctly +- Ensure backward compatibility with existing code + +## Best Practices + +- **New Modes**: Define in `instructor.Mode` enum, create handler, register via decorator +- **Error Handling**: Validate early, provide context, preserve exception chains +- **Testing**: Test both success and failure paths, verify registry registration +- **Documentation**: Document provider-specific behavior in handler docstrings +- **Type Safety**:
