Rahul Tarak caef908075 docs: refresh README(s) (#3801)
## Summary

Rewrites the stale root `README.md` against the current docs (structure
modeled on [earendil-works/pi](https://github.com/earendil-works/pi)'s
README).

- **Quickstarts** now use the session-based API (`composio.create()` →
`session.tools()`) that the docs treat as canonical, replacing the
legacy `composio.tools.get()` flow
- **Positioning** matches the docs welcome page: 1000+ pre-authenticated
toolkits, per-user sessions, auth, triggers, and a sandbox
- **New sections**: CLI install (curl / Homebrew / npm),
sessions-via-MCP note, repository layout, minimum runtime versions
- **Provider table** merged with package links; adds the Claude Agent
SDK providers (both SDKs) and the experimental Pi provider
(`@composio/experimental`); documents the Python
`composio-gemini`/`composio-google`/`composio-google-adk` split
- **Removed**: Rube section (no longer in docs), cover banner (replaced
with theme-adaptive brand logomark from brand.composio.dev),
master-branch pointer, internal OpenAPI-pull section, private
`@composio/ts-builders` listing

Docs-only change — no changeset needed.

# composio-gemini
Adapts Composio tools to the [`google-genai`](https://pypi.org/project/google-genai/) SDK as Python callables compatible with Gemini's Automatic Function Calling.
## Installation
```bash
pip install composio composio-gemini google-genai
```
Set `COMPOSIO_API_KEY` (create one at https://dashboard.composio.dev/settings) and `GOOGLE_API_KEY` (from https://aistudio.google.com/apikey) in your environment.
## Quickstart
`GeminiProvider` wraps each Composio tool as a typed Python callable. Pass the callables to `GenerateContentConfig(tools=...)` and the `google-genai` SDK derives function declarations from their signatures and executes tool calls automatically inside the chat loop; there is no manual tool-call handling.
```python
from composio import Composio
from composio_gemini import GeminiProvider
from google import genai
from google.genai import types
composio = Composio(provider=GeminiProvider())
client = genai.Client()
# Create a session for your user
session = composio.create(user_id="user_123")
tools = session.tools()
config = types.GenerateContentConfig(tools=tools)
chat = client.chats.create(model="gemini-3-pro-preview", config=config)
response = chat.send_message(
"Send an email to john@example.com with the subject 'Hello' and body 'Hello from Composio!'"
)
print(response.text)
```
If you disable Automatic Function Calling and handle function calls yourself, `composio.provider.handle_response(response)` executes the function calls in a Gemini response and returns `Part` objects ready to send back.
## composio-gemini vs composio-google
This package targets the `google-genai` SDK (`from google import genai`). [`composio-google`](../google) targets the older Vertex AI SDK (`vertexai.generative_models`). For new projects, Google recommends `google-genai`, so use this package.
