identa-sdk 0.4.3

SDK for Identa - Agent Evaluation

Identa SDK 🚀

The user-facing toolkit for evaluating and migrating LLM-based agents. Identa provides a zero-friction experience for LangGraph, PydanticAI, and LangChain agents.

Getting Started

1. Installation

pip install identa-sdk

Features

1. Evaluation Engine

The evaluate function executes your agent against test suites and computes metrics across your agent's graph/flow.

import identa

# Define a test suite
suite = [
    {"input": {"query": "Fly to Paris"}, "expected": {"destination": "CDG"}}
]

# Run evaluation with metrics
results = identa.evaluate(
    agent=my_agent, 
    suite=suite,
    metrics=["accuracy", "latency"],
    resolution="graph"
)

print(results.report())

2. Tracing Service

Use the context-aware span collector to debug agent execution in real-time.

import identa

# Start a trace session
with identa.trace("flight-booking-flow") as tracer:
    # Any agent calls within this block are automatically spanned
    response = my_agent.run("Book a flight to Tokyo")
    
# Retrieve trace data
spans = tracer.get_spans()

3. Migration Engine

Validate and apply model-binding swaps (e.g., swapping gpt-4o for claude-3-5-sonnet) safely.

from identa.sdk.migration import MigrationEngine

engine = MigrationEngine(workspace="travel_agent")

# Validate if the swap is safe based on structural drift
is_safe = engine.validate_swap(
    source_model="gpt-4o", 
    target_model="claude-3-5-sonnet"
)

if is_safe:
    engine.apply_swap(target_model="claude-3-5-sonnet")

4. Reproduction Engine

Replay previous experiments and detect structural drift between the original run and the current state.

from identa.sdk.reproduction import ReproductionEngine

repro = ReproductionEngine(workspace="travel_agent")

# Replay a failed run
analysis = repro.replay(run_id="run_123")

if analysis.has_drift:
    print(f"Structural drift detected: {analysis.drift_details}")

CLI

Identa comes with a CLI to manage your runs and view results.

# List all runs in a workspace
identa runs list --workspace travel_agent

# Show details of a specific run
identa runs show <run_id>
