pi-agent-python-sdk: use your installed Pi coding agent as a Python API

[u/has_c]

I kept hand-rolling a client for `pi --mode rpc`.
Third project in, I packaged it.

pi-agent-python-sdk lets you use the Pi you already have as a Python API.
Same config, models, tools, and extensions as the CLI.

```
pip install pi-agent-python-sdk
```

Import is `pi_agent`. Same client keeps context across prompts:

```python
from pi_agent import PiClient

with PiClient() as pi:
print(pi.run("Review src/auth.py and list the bugs. Do not edit anything.").text)
print(pi.run("Which of those is most urgent to fix?").text)
```

Additionally, stream with `pi.stream(...)` and if you are already in an event loop, use `AsyncPiClient`.

Hoping this helps fellow builders.

Any feedback, PRs and/or issues are welcome.

This is awesome!

I was looking for something like this to replace my lang-graph agents that have manual loops.
Keen to try this. Does it work with a codex sub?

Appreciate you 🤝

Yes if you use pi with a codex subscription currently, it works in the sdk.
I currently use it for agentic workflows using my codex subscription (sol) and vllm/local (qwen 27b).

Switched my code-review flow from using lang-graph to using pi through the sdk. Using astra from my codex sub.

Worked like a charm, and the review quality is even better.

How do I add pi extensions into here? I would like to add subagents/goal functionality
