The E2E badge hard-codes 17/17, but scripts/run_agent_scenarios.py now also reports .robot files as scenarios, which will change the total. Update the badge (or adjust the runner) so the displayed E2E count matches the workflow output.

Copilot uses AI. Check for mistakes.

## What Is This?
## Why This Repository?

This is **the most comprehensive collection of Python samples** for the [GitHub Copilot SDK](https://github.com/github/copilot-sdk). Unlike minimal "hello world" examples, these are **production-ready patterns** you can actually use:

This repository demonstrates the [GitHub Copilot SDK for Python](https://github.com/github/copilot-sdk/tree/main/python) through practical,single-file scripts. Each script is:
- βœ… **17 complete samples** β€” streaming, tools, BDD testing, browser automation, code review, and more
- βœ… **Proven in CI** β€” All samples run end-to-end with `gpt-5-mini` (GitHub's free tier model)
- βœ… **Single-file simplicity** β€” Each sample is self-contained and ready to run
- βœ… **Real-world patterns** β€” API testing, log analysis, test data generation, git commit messages
- βœ… **Best practices** β€” Type hints, async/await, proper error handling, structured outputs

- **Self-contained** β€” One `.py` file, ready to run
- **Practical** β€” Real-world automation use cases
- **Modern Python** β€” Type hints, async/await, argparse
- **Zero boilerplate** β€” No setup.py, no project scaffolding
**Perfect whether you're exploring the SDK for the first time or building production AI agents.**

## What Is This?

The GitHub Copilot SDK gives you programmatic access to the same AI agent runtime powering Copilot CLI and Copilot Chat.
The [GitHub Copilot SDK](https://github.com/github/copilot-sdk/tree/main/python) gives you programmatic access to the same AI agent runtime powering Copilot CLI and VS Code. This repository shows you how to use it effectively through practical, battle-tested examples.

Each script demonstrates a key SDK capability:
- AI conversation patterns (streaming, multi-turn, interactive)
- Custom tool definitions (function calling)
- Real-world automation (browser control, code review, testing)
- Production patterns (error handling, retries, structured output)

## AI-Enhanced Testing

These samples show how to integrate AI validation into established test frameworks β€” proving that Copilot SDK agents work correctly using the **same tools enterprises already use**.

**πŸ§ͺ pytest ([pytest_ai_validation.py](samples/pytest_ai_validation.py))**
- AI-as-judge pattern: one AI call validates another's output
- Deterministic + AI assertions: `ast.parse`, `json.loads` + AI relevance checks
- `copilot_session` fixture for test lifecycle
- Runs standalone OR with `pytest -v`

**πŸ€– Robot Framework ([copilot_bdd.robot](samples/copilot_bdd.robot) + [robot_copilot_library.py](samples/robot_copilot_library.py))**
- BDD/Gherkin syntax: `Given I have a Copilot session / When I ask Copilot to generate code / Then the code should be valid Python`
- Python keyword library wrapping the entire Copilot SDK
- Enterprise-ready: integrates AI agent testing into existing Robot Framework suites
- 4 scenarios: code generation, bug detection, JSON output, concept explanation

```bash
# Run pytest AI tests
pytest samples/pytest_ai_validation.py -v

# Run Robot Framework BDD tests
robot samples/copilot_bdd.robot

# Both also run standalone (no test framework required)
python samples/pytest_ai_validation.py

## Why Python + Copilot SDK?

| Traditional Approach | This Repository |
**Best SDK Sample Collection Available:**
| This Repository | Typical SDK Examples |
|---|---|
| Create project directory | Just create a `.py` file |
| Write `setup.py` or `pyproject.toml` | `requirements.txt` only |
| Manage dependencies manually | One `pip install` command |
| Multiple files for simple tasks | Single file, pure Python |
| Project scaffolding overhead | Zero ceremony |

Python is already the language of choice for quick scriptsβ€”this repository shows how to make them AI-powered with minimal effort.
| 17 production-ready samples | 2-3 "hello world" scripts |
| E2E tested in CI (see runs) | Untested or manual-only |
| Real-world use cases | Toy examples |
| Error handling + best practices | Happy path only |
| Free tier model (gpt-5-mini) | Requires expensive models |
| Single-file simplicity | Complex project structure |

## CI/CD
**Why Python?**
Python is already the go-to language for quick automation scripts. This repository shows how to make them AI-powered with the same simplicity you expect from Python.

This repository includes GitHub Actions CI that:
## CI/CD & Quality

- βœ… Lints (ruff)
- βœ… Checks syntax (`compileall`)
- βœ… Runs import smoke tests (so samples keep working for contributors)
This repository includes comprehensive CI/CD:

Because end-to-end runs require network + authentication (and can consume quota), live AI calls are **opt-in**.
**Default CI** ([ci.yml](.github/workflows/ci.yml)) β€” Runs on every push:
- βœ… Lints with ruff
- βœ… Syntax validation (`compileall`)
- βœ… Import smoke tests (ensures samples stay valid)

- Default CI: [.github/workflows/ci.yml](.github/workflows/ci.yml)
- Optional E2E proof (manual): [.github/workflows/agent-scenarios.yml](.github/workflows/agent-scenarios.yml)
**E2E Proof** ([agent-scenarios.yml](.github/workflows/agent-scenarios.yml)) β€” Optional, manual trigger:

The README says the E2E workflow β€œRuns all 15 samples”, but the repo now has 17 sample scripts (and the PR summary says 15 β†’ 17). Update this count (and ensure it stays consistent with what run_agent_scenarios.py reports).

Suggested change
- βœ… Runs all 15 samples with real AI calls
- βœ… Runs all 17 samples with real AI calls (as defined in `run_agent_scenarios.py`)

Copilot uses AI. Check for mistakes.
- βœ… Captures full execution transcripts
- βœ… Uses `gpt-5-mini` (free tier, no cost concerns)
- βœ… Proves every sample works end-to-end
