To create reliable selectors (e.g. name:Seven, role:Button, window:Calculator), you need to inspect the Accessibility Tree of your OS. Here's how to explore UI elements on each platform:
- Tool: Accessibility Insights for Windows
- Alt: Inspect.exe (comes with Windows SDK)
- Usage: Open the app you want to inspect → launch Accessibility Insights → hover or use keyboard navigation to explore the UI tree (Name, Role, ControlType, AutomationId).
These tools show you the
Name,Role,ControlType, and other metadata used in Terminator selectors.
- Tool: Accessibility Inspector
-
Usage: Comes with Xcode → Open
Xcode > Open Developer Tool > Accessibility Inspector→ Use the target icon to explore UI elements on screen.
-
Tool: Accerciser
-
Install:
sudo apt install accerciser
-
Usage: Launch Accerciser → Select the window/app → Browse the accessible widget tree.
Once you identify the structure of your UI:
# Sample pattern
desktop.locator('window:Calculator')
.locator('role:Button')
.locator('name:Seven')You can build and debug selector paths incrementally using .locator() chaining.

LangChain provides a set of ready-to-use components for working with language models and a standard interface for chaining them together to formulate more advanced use cases (e.g. chatbots, Q&A with RAG, agents, summarization, extraction, etc.). The components can be grouped into a few core modules: * **Model I/O:** LangChain offers a unified API for interacting with various LLM providers (e.g. OpenAI, Google, Mistral, Ollama, etc.), allowing developers to switch between them with ease. Additionally, it provides tools for managing model inputs (prompt templates and example selectors) and parsing the resulting model outputs (output parsers). * **Retrieval:** assists in loading user data (via document loaders), transforming it (with text splitters), extracting its meaning (using embedding models), storing (in vector stores) and retrieving it (through retrievers) so that it can be used to ground the model's responses (i.e. Retrieval-Augmented Generation or RAG). * **Agents:** "bots" that leverage LLMs to make informed decisions about which available tools (such as web search, calculators, database lookup, etc.) to use to accomplish the designated task. The different components can be composed together using the LangChain Expression Language (LCEL).

Sycamore uses your choice of generative AI models to make these operations simple and effective, and it enables quick experimentation and iteration. Additionally, Sycamore uses OpenSearch for indexing, enabling hybrid (vector + keyword) search, retrieval-augmented generation (RAG) pipelining, filtering, analytical functions, conversational memory, and other features to improve information retrieval.
