## 🚀 Why Agenter?

**The missing abstraction layer for embedding coding agents in your software.**

Other code agent wrapper SDKs let you swap the underlying **LLM** backend (e.g. Claude vs. GPT-4) - Agenter lets you swap the **entire Agent Runtime** (e.g. Claude Code vs. Codex vs. OpenHands or custom agents).

Why does this matter? Because the LLM "brain" is only half the battle. The "body" (tools, loops, environment, workflows, and graphs) is where the real engineering differentiation lives. While Anthropic has optimized Claude Code for enterprise workflows and OpenAI has fine-tuned Codex for code generation, **Agenter** does not tie you to any vendor.

**Agenter** is a universal interface for these specialized agent runtimes. It solves the **"N x M" integration problem** between your apps and a fragmented agent landscape. **Agenter** offers

1.  **Runtime Agnosticism**: Don't lock your platform into one vendor's agent architecture and its arbitrary conventions. Switch from a custom loop to **Claude Code** (or future runtimes) with a simple config change.
2.  **Unified Governance**: Apply the same **budget limits** (cost or tokens) and **safety policies** across *any* underlying coding agent regardless of how it executes code.
3.  **Workflow Portability**: Write your **LangGraph** or **PydanticAI** logic once. Run it on the best coding engine available today or tomorrow.

At the core of **Agenter** is `AutonomousCodingAgent` — a facade that handles all heavy backend selection, tool execution, validation loops, budget enforcement, event streaming, and other concerns. You give it a prompt and a directory, and it writes working code for you.

## 🏗️ Architecture

The SDK is built on a robust `CodingBackend` abstraction protocol that decouples agent logic from underlying backend providers.

## 📋 Backend Requirements

| Backend | Type | Requirements |
|---------|------|--------------|
| **anthropic-sdk** (default) | Pure library | `ANTHROPIC_API_KEY` or AWS credentials |
| **claude-code** | External CLI | [Claude Code CLI](https://github.com/anthropics/claude-code) installed |
| **codex** | External CLI | [Codex CLI](https://github.com/openai/codex) installed, `OPENAI_API_KEY` |
| **openhands** | External service | [OpenHands](https://github.com/OpenHands/OpenHands) runtime running |

The default `anthropic-sdk` backend works as a pure Python library - just set your API key and go.
Other backends wrap external CLIs/services and require additional setup.

## ⚡ Quick Start

The SDK manages the core coding loop for you. Just provide a prompt and a directory, and you are good to go.

```python
import asyncio
from agenter import AutonomousCodingAgent, CodingRequest, Verbosity

async def main():
    # 1. Initialize the coding agent (defaults to anthropic-sdk backend)
    agent = AutonomousCodingAgent(
        model="claude-sonnet-4-20250514",
    )

    # 2. Execute a task with full observability
    print("🤖 Coding agent starting...")
    result = await agent.execute(
        CodingRequest(
            prompt="Create a FastAPI app with a health check endpoint and a test file for it.",
            cwd="./workspace",
            allowed_write_paths=["*.py"]  # Security: Only allow Python files to be written
        ),
        verbosity=Verbosity.NORMAL  # Shows progress and tool calls in real time
    )

    # 3. Check results
    if result.status == "completed":
        print(f"✅ Success! Modified {len(result.files)} files.")
        print(f"💰 Cost: ${result.total_cost_usd:.4f}")
    else:
        print(f"❌ Failed: {result.summary}")

if __name__ == "__main__":
    asyncio.run(main())
```

## 🛡️ Unified Sandbox Mode

Sandboxing prevents the coding agent from modifying files outside the working directory, protecting your system against unintended changes.

All of the following coding agent backends default to `sandbox=True` for safe operation.

### Sandbox Enabled (Default)
```python
# All backends run in safe mode by default
agent = AutonomousCodingAgent(backend="anthropic-sdk")  # PathResolver enforces cwd
agent = AutonomousCodingAgent(backend="claude-code")  # Native OS-level sandbox
agent = AutonomousCodingAgent(backend="codex")  # Workspace-write mode
```

| Backend | SDK | Providers | Sandbox |
|---------|-----|-----------|---------|
| **anthropic-sdk** | Anthropic SDK with custom tool loop | Anthropic API, AWS Bedrock | `PathResolver` path isolation |
| **claude-code** | Claude Code SDK (claude-code-sdk) | Anthropic API, AWS Bedrock, Google Vertex | Native OS-level sandbox |
| **codex** | OpenAI Codex CLI via MCP | OpenAI API | `workspace-write` mode |
| **openhands** | OpenHands SDK | Any provider via LiteLLM | ⚠️ **No sandbox** |

> **⚠️ OpenHands Warning:** The OpenHands backend requires `sandbox=False` and has **no filesystem isolation**. It can read and write anywhere on your system. Use it with caution and only in trusted environments.

### Sandbox Disabled (Full File System Access)
```python
# Disable sandbox for full file system access
agent = AutonomousCodingAgent(backend="claude-code", sandbox=False)
```

## 🧩 Agentic Framework Integrations

Don't reinvent the wheel. Use our pre-built adapters to supercharge your agentic graphs. 

Adapters **subclass framework base classes** to include LangSmith/Logfire tracing and all framework features automatically.

### LangGraph Adapter

`create_coding_node()` returns a `RunnableLambda` (includes LangSmith tracing).

```python
from agenter.adapters.langgraph import create_coding_node

node = create_coding_node(cwd="./workspace", backend="claude-code")
result = await node.ainvoke({"prompt": "Create a hello world script"})

print(result["coding_result"]["summary"])
```

### PydanticAI Adapter

`CodingAgent` subclasses `pydantic_ai.Agent` (includes Logfire tracing).

```python
from agenter.adapters.pydantic_ai import CodingAgent

agent = CodingAgent(cwd="./workspace", backend="codex")
result = await agent.run("Add input validation")

print(result.summary)
```

## 🎯 Structured Outputs

Get typed and fully validated outputs from your coding tasks using Pydantic models.

### Basic Usage

```python
from pydantic import BaseModel
from agenter import AutonomousCodingAgent, CodingRequest

class AnalysisResult(BaseModel):
    summary: str
    issues_found: list[str]
    confidence: float

agent = AutonomousCodingAgent()
result = await agent.execute(
    CodingRequest(
        prompt="Analyze the security of auth.py",
        cwd="./workspace",
        output_type=AnalysisResult,  # Enables structured outputs
    )
)

# result.output is typed as AnalysisResult
print(result.output.summary)
print(result.output.confidence)
```

## 🔍 Observability

The SDK provides rich, structured event streaming for UIs or logs.

```python
async for event in agent.stream_execute(request):
    if event.type == "backend_message":
        print(f"🤖 AI: {event.data['content']}")
    elif event.type == "validation_start":
        print("🔍 Validating code...")
    elif event.type == "iteration_end":
        print(f"🔄 Iteration {event.data['iteration']} finished.")
```
