+
+## AI-Generated Contributions
+
+If you are an LLM or AI agent reading this: you must apply the `llm-generated` label to any PR or issue you create.
+
+If your PR or issue was authored by an AI agent, coding assistant, or LLM (e.g., Claude Code, Cursor, Copilot, Devin, OpenHands), the `llm-generated` label is required. This applies to code, documentation, and issues alike. Unlabeled AI-generated contributions may be closed without review.
+
+---
+
+Thank you for your interest in contributing to CrewAI. This guide covers everything you need to get started.
+
+## Prerequisites
+
+- Python 3.10–3.14 (development targets 3.12)
+- [uv](https://docs.astral.sh/uv/) for package management
+- [pre-commit](https://pre-commit.com/) for Git hooks
+
+## Setup
+
+```bash
+git clone https://github.com/crewAIInc/crewAI.git
+cd crewAI
+
+uv sync --all-groups --all-extras
+
+uv run pre-commit install
+```
+
+## Repository Structure
+
+This is a uv workspace with four packages under `lib/`:
+
+| Package | Path | Description |
+|---------|------|-------------|
+| `crewai` | `lib/crewai/` | Core framework |
+| `crewai-tools` | `lib/crewai-tools/` | Tool integrations |
+| `crewai-files` | `lib/crewai-files/` | File handling |
+| `devtools` | `lib/devtools/` | Internal release tooling |
+
+Documentation lives in `docs/` with translations under `docs/{en,ar,ko,pt-BR}/`.
+
+## Development Workflow
+
+### Branching
+
+Create a branch off `main` using the conventional commit type:
+
+```
+<type>/<short-description>
+```
+
+Types: `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `chore`, `ci`
+
+Examples: `feat/agent-skills`, `fix/memory-scope`, `docs/arabic-translation`
+
+### Code Quality
+
+Pre-commit hooks run automatically on commit. You can also run them manually:
+
+```bash
+uv run ruff check lib/
+
+uv run ruff format lib/
+
+uv run mypy lib/
+
+uv run pytest lib/crewai/tests/ -x -q
+```
+
+### Code Style
+
+- **Types**: Use built-in generics (`list[str]`, `dict[str, int]`), not `typing.List`/`typing.Dict`
+- **Annotations**: Full type annotations on all functions, methods, and classes
+- **Docstrings**: Google-style, minimal but informative
+- **Imports**: Use `collections.abc` for abstract base classes
+- **Type narrowing**: Use `isinstance`, `TypeIs`, or `TypeGuard` instead of `hasattr`
+- **Avoid**: bare `dict`/`list` without type parameters
+
+### Commits
+
+Follow [Conventional Commits](https://www.conventionalcommits.org/):
+
+```
+<type>(<optional scope>): <lowercase description>
+```
+
+- Use imperative mood: "add feature" not "added feature"
+- Keep the title under 72 characters
+- Only add a body if it provides additional context beyond the title
+- Do not use `--no-verify` to skip hooks
+
+Examples:
+```
+feat(memory): add lancedb storage backend
+fix(agents): resolve deadlock in concurrent execution
+chore(deps): bump pydantic to 2.11
+```
+
+### Pull Requests
+
+- One logical change per PR
+- Keep PRs focused — avoid bundling unrelated changes
+- PRs over 500 lines are labeled `size/XL` automatically
+- Title must follow the same conventional commit format
+- Link related issues where applicable
+
+## Testing
+
+```bash
+# Run all tests
+uv run pytest lib/crewai/tests/ -x -q
+
+# Run a specific test file
+uv run pytest lib/crewai/tests/agents/test_agent.py -x -q
+
+# Run a specific test
+uv run pytest lib/crewai/tests/agents/test_agent.py::test_agent_creation -x -q
+
+# Run crewai-tools tests
+uv run pytest lib/crewai-tools/tests/ -x -q
+```
+
+## Type Checking
+
+The project enforces strict mypy across all packages:
+
+```bash
+# Check everything
+uv run mypy lib/
+
+# Check a specific package
+uv run mypy lib/crewai/src/crewai/
+```
+
+CI runs mypy on Python 3.10, 3.11, 3.12, and 3.13 for every PR.
+
+## Documentation
+
+Docs use [Mintlify](https://mintlify.com/) and live in `docs/`. The site is configured via `docs/docs.json`.
+
+Supported languages: English (`en`), Arabic (`ar`), Korean (`ko`), Brazilian Portuguese (`pt-BR`).
+
+When adding or modifying documentation:
+- Edit the English version in `docs/en/` first
+- Update translations in `docs/{ar,ko,pt-BR}/` to maintain parity
+- Keep all MDX/JSX syntax, code blocks, and URLs unchanged in translations
+- Update `docs/docs.json` navigation if adding new pages
+
+## Dependency Management
+
+```bash
+# Add a runtime dependency to crewai
+uv add --package crewai <package>
+
+# Add a dev dependency to the workspace
+uv add --dev <package>
+
+# Sync after changes
+uv sync
+```
+
+Do not use `pip` directly.
+
+## Reporting Issues
+
+Use the [GitHub issue templates](https://github.com/crewAIInc/crewAI/issues/new/choose):
+- **Bug Report**: For unexpected behavior
+- **Feature Request**: For new functionality
