Before You Deploy It.
Four live simulation modules. Paste any URL. Get real output.
AXTree pruning · Vision grounding · Flow execution · Blueprint validation.
# AXTree Semantic Grounding
DOM pruning + semantic role extraction for machine ingestion. Paste any URL and watch the engine reduce thousands of DOM nodes into a dense, agent-readable semantic structure in under 500ms.
AXTree Extraction works in three phases:
1. FETCH — The engine spins up a sterile V8 isolate and navigates to the target URL using a headless Chromium instance with full JavaScript execution.
2. PRUNE — The raw DOM is filtered using AGENSTAB's semantic pruning algorithm. Decorative elements, hidden nodes, and semantically empty containers are removed.
3. SERIALIZE — The pruned tree is serialized into a dense, token-efficient format optimized for LLM ingestion, with ARIA attributes preserved as metadata.
# Vision Spatial Mapping
VLM spatial grounding simulation. The engine locates elements by visual coordinates — no DOM access required.
The VLM processes visual layout independently of the DOM, identifying interactive elements, navigation structures, and content zones with coordinate-level precision.
# Flow Orchestration
Build a deterministic action sequence. Each step executes in the sovereign isolate and streams results back in real time.
The Flow engine queues actions into a deterministic pipeline. Each step is executed sequentially with full error handling, retry logic, and step-level logging.
# Blueprint IDE
Author, validate, and export JSON-RPC blueprints. Pre-validated schemas deploy directly to the sovereign cloud with zero reformat.
