# Sepurux Python SDK

[![PyPI](https://img.shields.io/pypi/v/sepurux)](https://pypi.org/project/sepurux/)
[![Python](https://img.shields.io/pypi/pyversions/sepurux)](https://pypi.org/project/sepurux/)
[![CI](https://github.com/sepurux/sepurux-platform/actions/workflows/ci.yml/badge.svg)](https://github.com/sepurux/sepurux-platform/actions/workflows/ci.yml)

Record agent traces, run reliability campaigns, and instrument OpenAI or LangChain workflows — all from Python.

## Install

```bash
pip install -e sdk
```

## Quick start

```python
import os

from sepurux import SepuruxClient

os.environ["SEPURUX_API_BASE_URL"] = "http://localhost:8000"
os.environ["SEPURUX_API_KEY"] = "sepurux-dev-key"
os.environ["SEPURUX_PROJECT_ID"] = "22222222-2222-2222-2222-222222222222"

with SepuruxClient.from_env() as client:
    with client.trace("example_task", {"user_id": "u-123"}) as trace:
        trace.model_step("plan", {"goal": "create issue"}, output={"ok": True})
        trace.tool_call("jira.create_issue(commit)", {"summary": "SDK test"})
        trace.tool_result("jira.create_issue(commit)", {"issue_id": "OPS-123"})

    print("trace_id:", trace.trace_id)
```

This is the intended ergonomic path:
- `SepuruxClient.from_env()` reads `SEPURUX_API_BASE_URL`, `SEPURUX_API_KEY`, and `SEPURUX_PROJECT_ID`
- `client.trace(...)` records and uploads automatically on exit
- `trace.trace_id` and `trace.run_id` are available after the context closes

## LangSmith-style ergonomics

### Auto-upload trace context

```python
from sepurux import SepuruxClient

client = SepuruxClient.from_env()

with client.trace(
    "checkout_refund",
    {"ticket_id": "t-123"},
    campaign_id="refund_reliability",
    mutation_pack="sepurux.core.reliability",
) as trace:
    trace.model_step("triage", {"text": "Refund the duplicate charge"})
    trace.tool_call("payments.refund", {"payment_id": "pay_123", "amount": 4200})
    trace.tool_result("payments.refund", {"refund_id": "rf_123", "status": "queued"})

print(trace.trace_id)
print(trace.run_id)
```

### `@traceable` decorator

Works with both sync and `async def` functions:

```python
from sepurux import SepuruxClient

client = SepuruxClient.from_env()

# Sync function
@client.traceable(campaign_id="refund_reliability")
def score_refund_risk(amount: int, currency: str) -> dict:
    return {"risk": "medium", "approve": amount < 10000, "currency": currency}

result = score_refund_risk(4200, "usd")

# Async function — same decorator, awaitable result
@client.traceable(campaign_id="refund_reliability")
async def fetch_risk_score(payment_id: str) -> dict:
    data = await some_async_api(payment_id)
    return {"risk": data["score"]}

result = await fetch_risk_score("pay_123")
```

### Global configuration

```python
from sepurux import configure, trace, traceable

configure()

@traceable()
def classify_ticket(text: str) -> dict:
    return {"label": "bug", "priority": "p2"}

with trace("support_session", {"channel": "email"}) as rec:
    rec.model_step("classify", {"text": "checkout timed out"})
```

## API

### `SepuruxClient`

```python
SepuruxClient(base_url, api_key=None, project_id=None, timeout=30, sdk_header=None)
SepuruxClient.from_env(...)
```

The SDK automatically sends `X-Sepurux-SDK: py/<version>` on requests.
Use `sdk_header` only if you need to override it manually.

Methods:
- `trace(task_name, task_input=None, campaign_id=None, mutation_pack=None) -> recorder`
- `traceable(name=None, campaign_id=None, mutation_pack=None) -> decorator`
- `upload_trace(trace: dict) -> str`
- `list_traces(limit=50, offset=0) -> list[dict]`
- `get_trace(trace_id, include_payload=False) -> dict`
- `get_trace_timeline(trace_id) -> list[dict]`
- `bootstrap_trace(trace_id) -> dict`
- `create_campaign(name, mutation_set, eval_set, mutation_pack_id=None) -> str`
- `preflight_run_inputs(trace_id, campaign_id) -> None`
- `start_run(trace_id, campaign_id, thresholds=None, preflight=False) -> str`
- `run_pack(campaign_id, mutation_pack) -> str`
- `get_run(run_id) -> dict`
- `get_ci_run(run_id) -> dict`
- `get_campaign_failures(campaign_id, run_id=None) -> list[dict]`
- `get_campaign_reliability(campaign_id, run_id=None) -> dict`

### `TraceBuilder`

`TraceBuilder` outputs backend-compatible traces:

```json
{
  "trace_version": "0.1",
  "source": "sdk",
  "task": {"name": "...", "input": {}},
  "events": []
}
```

### Recommended tracing flow

Use `client.trace(...)`, `client.traceable(...)`, or the global `trace(...)` / `traceable(...)`
helpers as the default integration path. Legacy helpers like `sepurux_trace(...)` and
`record_trace(...)` remain available for compatibility, but they are deprecated and no longer
the documented path.

### Server-side pack execution

```python
result = client.run_campaign("demo_campaign", mutation_pack="core.reliability")
print(result["run_id"])
print(result["reliability_score"])
print([failure["type"] for failure in result["failures"]])
```


## Integrations

### OpenAI

`instrument_openai` wraps any `openai.OpenAI` (or `AsyncOpenAI`) client and
automatically records every `chat.completions.create` call as an `llm_call`
event. Tool calls present in the response are also recorded. No manual
instrumentation required.

```bash
pip install sepurux openai
```

```python
import openai
from sepurux import SepuruxClient
from sepurux.integrations.openai import instrument_openai

client = SepuruxClient.from_env()
openai_client = openai.OpenAI()

with client.trace(
    "customer_refund_flow",
    {"ticket_id": "t-101"},
    campaign_id=os.environ["SEPURUX_CAMPAIGN_ID"],
) as trace:
    ai = instrument_openai(openai_client, recorder=trace)
    response = ai.chat.completions.create(
        model="gpt-4o",
        messages=[{"role": "user", "content": "Classify this support ticket"}],
    )

print(trace.trace_id)
print(trace.run_id)
```

**What gets recorded automatically:**
- `llm_call` event with model name, messages input, full response output, and latency
- `tool_call` events for any function calls returned by the model
- `failure` event if the API call raises an exception

For async usage, call `await ai.chat.completions.acreate(...)` — the wrapper
detects the async path automatically.

### LangChain

`SepuruxCallbackHandler` automatically records LLM calls, tool calls, and agent
outputs from any LangChain chain or agent. Requires `langchain-core`:

```bash
pip install sepurux langchain-core
```

```python
import os
from langchain_openai import ChatOpenAI
from langchain.agents import AgentExecutor, create_tool_calling_agent
from langchain_core.prompts import ChatPromptTemplate
from sepurux.integrations.langchain import SepuruxCallbackHandler

handler = SepuruxCallbackHandler(
    "customer_refund_flow",
    {"ticket_id": "t-101"},
    campaign_id=os.environ["SEPURUX_CAMPAIGN_ID"],
)

# Works with chains, agents, or any LangChain runnable
result = agent_executor.invoke(
    {"input": "Process refund for ticket t-101"},
    config={"callbacks": [handler]},
)

# Upload trace + start reliability run
handler.finish()
print(handler.trace_id)
print(handler.run_id)
```

Or use it as a context manager — `finish()` is called automatically on exit:

```python
with SepuruxCallbackHandler("refund_flow", campaign_id="...") as handler:
    result = chain.invoke(inputs, config={"callbacks": [handler]})

print(handler.trace_id)
```

**What gets recorded automatically:**
- LLM calls with model name, prompt input, generated output, and latency
- Tool calls with name and parsed arguments
- Tool results
- Agent final output


Optional environment variables:
- `SEPURUX_API_BASE_URL` (default `http://localhost:8000`)
- `SEPURUX_UI_BASE_URL` (default `http://localhost:3000`)
- `SEPURUX_API_KEY`
- `SEPURUX_PROJECT_ID`
- `SEPURUX_CAMPAIGN_ID` (if provided, script starts a run)
