+# CLAUDE.md — openai-agents-python (AiFeatures fork)
+
+Upstream: openai/openai-agents-python — lightweight, provider-agnostic multi-agent workflow framework (Python 3.10+). Used within iAiFy to build and test agent orchestration patterns against the OpenAI Responses/Chat Completions API and 100+ other LLMs.
+
+See AGENTS.md for the upstream agent instruction surface.
+
+## Quick Start
+
+```bash
+# Python 3.10+ required
+python -m venv .venv && source .venv/bin/activate
+
+# Install
+pip install openai-agents
+# or with uv:
+uv init && uv add openai-agents
+
+# With optional extras
+pip install 'openai-agents[voice]'    # voice support
+pip install 'openai-agents[redis]'    # Redis session backend
+
+# Run an example
+python examples/basic/hello_world.py
+```
+
+## Development
+
+```bash
+pip install -e ".[dev]"
+pytest               # run tests
+mypy src/            # type check
+ruff check .         # lint
+ruff format .        # format
+```
+
+## Architecture
+
+- `src/agents/` — Core SDK: Agent, Runner, Tools, Guardrails, Handoffs, Sessions, Tracing, Realtime
+- `examples/` — Reference implementations organized by feature area
+- `tests/` — Unit and integration tests
+- `docs/` — MkDocs documentation source
+
+Key concepts: **Agent** (instructions + tools + guardrails), **Runner** (sync/async execution), **Handoffs** (agent-to-agent delegation), **Sessions** (conversation history), **Tracing** (run visibility + debugging).
+
+## Conventions
+
+- Conventional commits (`feat:`, `fix:`, `docs:`, `chore:`)
+- Kebab-case file names, snake_case Python identifiers
+- Follow upstream openai/openai-agents-python release cadence for sync PRs
