execlave-sdk 1.1.0

Official Python SDK for the Execlave AI Governance Platform — tracing, policy enforcement, and framework auto-instrumentation for LangChain, OpenAI Agents SDK, and CrewAI

Execlave Python SDK

Official Python SDK for the Execlave AI Governance Platform. Provides tracing, agent registration, prompt-injection scanning, PII scrubbing, and OpenTelemetry integration for AI agents.

Framework integrations — drop in one callback/processor/helper for LangChain, OpenAI Agents SDK, or CrewAI. See the full docs or get an API key.

Installation

pip install execlave-sdk

With OpenTelemetry support:

pip install execlave-sdk[otel]

Quick Start

from execlave import Execlave

# Initialize the SDK
ag = Execlave(
    api_key="exe_prod_your_key_here",   # or set EXECLAVE_API_KEY env var
    base_url="https://api.execlave.com",  # defaults to https://api.execlave.com
    environment="production",
)

# Register an agent
agent = ag.register_agent(
    agent_id="my-assistant",
    name="Customer Support Bot",
    description="Handles tier-1 support queries",
    model="gpt-4o",
    framework="langchain",
    tags=["support", "production"],
)

# Record a trace using the decorator
@ag.trace
def answer(question: str) -> str:
    # Your LLM call here
    return llm.invoke(question)

result = answer("How do I reset my password?")

Agent Registration

Register agents to monitor them from the Execlave dashboard:

agent = ag.register_agent(
    agent_id="order-processor",
    name="Order Processor",
    description="Processes and validates customer orders",
    model="claude-3-sonnet",
    framework="custom",
    tags=["orders", "production"],
)

# Check agent status
print(agent.status)  # "active", "paused", etc.

Tracing

Decorator

The simplest way to trace function calls:

@ag.trace
def process_order(order_data: dict) -> dict:
    result = llm.invoke(json.dumps(order_data))
    return json.loads(result)

Context Manager

For more control over trace metadata:

with ag.start_trace(agent_id="my-assistant", session_id="sess_abc") as trace:
    trace.set_input({"question": "What is the refund policy?"})

    result = llm.invoke("What is the refund policy?")

    trace.set_output({"answer": result})
    trace.set_model("gpt-4o")
    trace.set_tokens(input=150, output=320)
    trace.set_cost(0.0045)

Manual Trace

trace = ag.start_trace(agent_id="my-assistant")
trace.set_input(user_query)

try:
    response = llm.invoke(user_query)
    trace.set_output(response)
    trace.set_status("success")
except Exception as e:
    trace.set_error(e)
finally:
    trace.end()

Trace Fields

Method	Description
set_input(data)	Input data (auto-serialized)
set_output(data)	Output data (auto-serialized)
set_model(name)	Model name (e.g., "gpt-4o")
set_tokens(input, output)	Token counts
set_cost(amount)	Cost in USD
set_status(status)	"success" or "error"
set_error(exception)	Records error info from an exception
set_metadata(dict)	Arbitrary key-value metadata
set_duration(ms)	Override duration in milliseconds

Privacy & PII Scrubbing

Built-in client-side PII scrubbing before data leaves your infrastructure:

ag = Execlave(
    api_key="exe_prod_xxx",
    privacy={
        "scrub_pii": True,           # Enable PII detection & redaction
        "scrub_fields": ["input", "output"],  # Fields to scan
    },
)

Detected PII types: email addresses, SSNs, credit card numbers, US phone numbers, IP addresses, API keys.

Prompt Injection Scanning

The SDK scans inputs for prompt-injection patterns before sending them to your LLM:

ag = Execlave(
    api_key="exe_prod_xxx",
    enable_injection_scan=True,  # Default: True
)

# Traces with detected injection attempts are flagged automatically

Detected patterns include: "ignore previous instructions", jailbreak attempts, system prompt extraction, and more.

Kill Switch / Pause Support

Execlave supports remote agent pausing via the dashboard:

from execlave import AgentPausedError

try:
    result = answer("Process this order")
except AgentPausedError:
    # Agent was paused by an admin — handle gracefully
    return "Service temporarily unavailable"

The SDK polls for status changes in the background (configurable interval).

OpenTelemetry Integration

Export Execlave traces as OpenTelemetry spans for unified observability:

from execlave import Execlave
from execlave.otel import configure_otel

# Initialize with OTel mode
ag = Execlave(
    api_key="exe_prod_xxx",
    mode="otel",
    otlp_endpoint="http://localhost:4318",  # Your OTel collector
)

# Configure the OTel pipeline
configure_otel(ag)

Requires the otel extra: pip install execlave-sdk[otel]

Configuration

Constructor Options

Parameter	Type	Default	Description
api_key	str	EXECLAVE_API_KEY env	Your Execlave API key
base_url	str	https://api.execlave.com	Execlave API URL
environment	str	"production"	Environment tag
async_mode	bool	True	Non-blocking trace ingestion
mode	str	"native"	"native" or "otel"
otlp_endpoint	str	None	OTel collector endpoint
batch_size	int	100	Traces per flush batch
flush_interval_seconds	int	10	Seconds between flushes
debug	bool	False	Enable debug logging
privacy	dict	{}	PII scrubbing config
enable_control_channel	bool	True	Enable status polling
enable_injection_scan	bool	True	Enable injection scanning

Environment Variables

Variable	Description
EXECLAVE_API_KEY	API key (alternative to constructor)
EXECLAVE_BASE_URL	Base URL (alternative to constructor)

Error Handling

from execlave import ExeclaveError, ExeclaveAuthError, AgentPausedError

try:
    ag = Execlave(api_key="exe_invalid")
    ag.register_agent(agent_id="test")
except ExeclaveAuthError:
    print("Invalid API key")
except AgentPausedError:
    print("Agent is paused")
except ExeclaveError as e:
    print(f"SDK error: {e}")

Async Trace Buffer

The SDK uses a non-blocking circular buffer (max 10,000 traces) with a background flush thread. Traces are batched and sent to the Execlave API automatically.

# Manual flush (e.g., before shutdown)
ag.flush()

# Graceful shutdown
ag.shutdown()
