+- **Python Version:** 3.13
+- **Package Manager:** uv (ALWAYS use `uv run` prefix)
+- **Linting:** prek, ruff
+- **Testing:** pytest (functions, not classes)
+- **Documentation:** Google-style docstrings

-## Tools you can use
+## Critical Commands
+
+### Always use `uv run` prefix
+```bash
+uv sync                              # Install/sync dependencies
+uv add <package>                     # Add new dependency
+uv run pytest                        # Run all tests
+uv run pytest -v -x                  # Verbose, stop on first failure
+uv run pytest tests/unit/            # Run specific test directory
+uv run prek run --all-files          # Run all linting checks using prek (compatible with pre-commit)
+uv run ruff check --fix .            # Lint and auto-fix
+uv run ruff format .                 # Format code
+```
 
-- **Lint:** `uv run prek run --all-files` Run linting.
-- **Add dependencies:** `uv add` Add project dependency
-- **Test:** `uv run pytest` (runs pytest, must pass before commits)
-- **Fix formatting:** `uv run ruff check --fix` (auto-fixes ESLint errors)
+### Pre-commit checklist
+```bash
+uv run ruff check --fix .
+uv run prek run --all-files
+uv run pytest
+```
 
-## Python Instructions
+## Code Conventions
 
-- Write clear and concise comments for each function.
-- Ensure functions have descriptive names and include type hints.
-- Provide docstrings following PEP 257 conventions.
-- Use the `typing` module for type annotations (e.g., `list[str]`, `dict[str, int]`).
-- Break down complex functions into smaller, more manageable functions.
+- **Line length:** 99 characters maximum
+- **Type hints:** Required for all function signatures
+- **Docstrings:** Google-style for public functions/classes
+- **Naming:** `snake_case` for functions/variables, `PascalCase` for classes
+- **Imports:** Standard library → third-party → local (separated by blank lines)
+- **Cyclomatic complexity:** Maximum 8 per function
+- **Function length:** Prefer <50 lines; split if longer
 
-## General Instructions
+### ✅ Good Example
+```python
+from pathlib import Path
+import json
 
-- Always prioritize readability and clarity.
-- For algorithm-related code, include explanations of the approach used.
-- Write code with good maintainability practices, including comments on why certain design decisions were made.
-- Handle edge cases and write clear exception handling.
-- For libraries or external dependencies, mention their usage and purpose in comments.
-- Use consistent naming conventions and follow language-specific best practices.
-- Write concise, efficient, and idiomatic code that is also easily understandable.
+def load_resource(resource_id: str, cache_dir: Path) -> dict[str, str]:
+    """
+    Load a resource from cache or fetch from remote source.
 
-## Code Style and Formatting
+    Args:
+        resource_id: Unique resource identifier
+        cache_dir: Directory for cached resources
 
-- Follow the **PEP 8** style guide for Python.
-- Maintain proper indentation (use 4 spaces for each level of indentation).
-- Ensure lines do not exceed 99 characters.
-- Place function and class docstrings immediately after the `def` or `class` keyword.
-- Use blank lines to separate functions, classes, and code blocks where appropriate.
-- Use Google style doc strings
+    Returns:
+        Dictionary containing resource data
 
-## Edge Cases and Testing
+    Raises:
+        ValueError: If resource_id is empty or invalid
+        FileNotFoundError: If resource not found in cache or remote source
+    """
+    if not resource_id:
+        raise ValueError("Resource ID cannot be empty")
 
-- Always include test cases for critical paths of the application.
-- Account for common edge cases like empty inputs, invalid data types, and large datasets.
-- Include comments for edge cases and the expected behavior in those cases.
-- Write unit tests for functions and document them with docstrings explaining the test cases.
+    cached_path = cache_dir / f"{resource_id}.json"
+    if cached_path.exists():
+        return json.loads(cached_path.read_text())
 
-## Example of Proper Documentation
+    result = fetch_from_remote(resource_id)
+    if result is None:
+        raise FileNotFoundError(f"Resource not found: {resource_id}")
+    return result
+```
 
+### ❌ Bad Example
 ```python
-import math
+def load(x):
+    # No type hints, vague name, silent failures
+    try:
+        return json.loads(Path(x).read_text())
+    except:
+        return {}
+```
 
-def calculate_area(radius: float) -> float:
-    """
-    Calculate the area of a circle given the radius.
+## Testing Guidelines
 
-    Parameters:
-    radius (float): The radius of the circle.
+### Pytest-style functions (NOT unittest classes)
+# ✅ Good - pytest function with fixtures
+```python
+def test_processor_handles_empty_input(sample_data, processor):
+    result = processor.process(sample_data, max_items=100)
+    assert all(len(item) <= 100 for item in result)
+```
 
-    Returns:
-    float: The area of the circle, calculated as π * radius^2.
-    """
-    return math.pi * radius ** 2
+# ❌ Bad - unittest class style
+```python
+class TestProcessor(unittest.TestCase):
+    def test_empty_input(self):
+        self.assertTrue(...)
 ```
 
-Boundaries
+## Error Handling
+
+- Define custom exceptions in `python_template/exceptions.py`
+- Inherit from a base project exception for easy catching
+- Include context in exception messages
+```python
+# ✅ Good
+class DocumentNotFoundError(LovligError):
+    """Raised when a document cannot be found."""
+    def __init__(self, doc_id: str):
+        super().__init__(f"Document not found: {doc_id}")
+        self.doc_id = doc_id
+
+# ❌ Bad
+raise Exception("not found")
+```
 
-- ✅ **Always:** Write to `/` and `tests/`, run tests before commits, follow naming conventions
-- ✅ **Always:** Update docs after code changes
-- ⚠️ **Ask first:** Database schema changes, adding dependencies, modifying CI/CD config
-- 🚫 **Never:** Commit secrets or API keys
+### Testing patterns
+- Use descriptive names: `test_<component>_<scenario>_<expected_outcome>`
+- Prefer fixtures over setup/teardown methods
+- Use `assert` directly, no `self.assertEqual()`
+- Put shared fixtures in `tests/conftest.py`
+- Never create throwaway test scripts outside `tests/`
+
+### Test organization by speed
+- `tests/unit/` - Fast (<100ms), no external dependencies
+- `tests/integration/` - Slower, requires services (DB, API)
+- `tests/e2e/` - Full workflow tests
+
+## Architecture Patterns
+
+- **Separation of concerns:** Keep data access, business logic, and presentation separate
+- **Dependency injection:** Pass dependencies as parameters, avoid global state
+- **Error handling:** Raise specific exceptions, don't catch and ignore
+- **Async:** Use `async`/`await` for I/O-bound operations
+
+## Documentation Requirements
+
+- Update `docs/` when adding features or changing behavior
+- Write analysis reports to `docs/wip/` after completing complex tasks
+- Keep `README.md` concise - detailed docs go in `docs/`
+- Include "why" in comments for non-obvious design decisions
+
+## Boundaries
+
+### ✅ Always
+- Run `uv run pytest` before any commit
+- Use `uv run` prefix for ALL Python commands
+- Write tests for new functionality
+- Run `uv run ruff check --fix` on changed files
+- Use type hints on all function signatures
+- Ask clarifying questions about unclear requirements
+
+### ⚠️ Ask First
+- Adding new dependencies with `uv add`
+- Database schema or migration changes
+- Modifying CI/CD configuration
+- Changing core architecture patterns
+- Deleting existing tests or code
+
+### 🚫 Never
+- Commit secrets, API keys, or `.env` files
+- Use `python` or `pytest` directly (always `uv run`)
+- Remove failing tests without explicit approval
+- Create test files outside `tests/` directory
+- Modify `pyproject.toml` or lockfiles manually
+- Catch exceptions without handling them (`except: pass`)
+- Use `pip` instead of `uv`
