# uipath-core — UiPath Core abstractions

License: unclear · Maintenance: active · Downloads: 1.0M/mo

## What it is and what it does

UiPath Core is a foundational library that bundles abstractions and utilities for building applications on top of the UiPath Python SDK. It provides structured error handling with category-based classification, JSON serialization that handles Pydantic models (v1 & v2), dataclasses, enums, and datetime objects, and OpenTelemetry integration for distributed tracing with automatic execution ID propagation. It also includes deterministic guardrails for rule-based validation of inputs and outputs, and Pydantic models that define the UiPath conversation event protocol for streaming interactions between clients and LLM/agent backends.

The package is designed as a shared foundation for UiPath SDK components and applications. Its three runtime dependencies—opentelemetry-instrumentation, opentelemetry-sdk, and pydantic—are pinned to specific version ranges. It targets Python 3.11 and later and is actively maintained, with recent releases and an open repository.

Use it for:

- Instrument sync and async functions with OpenTelemetry tracing and automatic execution ID tracking for distributed debugging.
- Serialize complex Python objects including Pydantic models and dataclasses to JSON in a unified way.
- Validate function inputs and outputs against deterministic rules (word patterns, numeric constraints, boolean assertions).
- Build conversation-driven applications using the standardized UiPath event protocol with tool calls and human-in-the-loop interrupts.
- Handle UiPath trigger errors with category-based classification for deployment, system, and user-level faults.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides core abstractions, data models, and utilities for the UiPath Python SDK, including error handling, JSON serialization, OpenTelemetry tracing, guardrails validation, and conversation event protocols.

Yes, if you are building on the UiPath Python SDK or need its abstractions. The package is actively maintained, has low install friction, and provides well-structured utilities for tracing, serialization, and validation. However, verify the license status before use in proprietary or redistributed contexts, as it is currently unclear.

## Install

pip install uipath-core
uv add uipath-core
poetry add uipath-core

## Installing uipath-core

Before you install: Low friction installation with a pure Python wheel. Active maintenance with a recent release within 30 days and an up-to-date repository. Requires Python 3.11 or later.

License in practice: License status is unclear—no SPDX identifier or raw license text is available. Verify licensing terms before use in proprietary or redistributed code.

Quickstart:

pip install uipath-core

from uipath.core.tracing import traced

@traced(name="my_operation", run_type="tool")
def do_work(input: str) -> str:
    return input.upper()

Requires Python 3.11 or later.

Verify before relying:

- Whether the unclear license status reflects a missing declaration or an intentional choice; contact maintainers for clarification.
- Whether guardrails validation is suitable for production security use or intended for development-time checks only.
