E2LLM releases open SiFR format for deterministic web page data capture

By PulseAugur Editorial · [1 sources] ·

E2LLM has released SiFR, a new format specification for capturing web page data, along with its associated taxonomy and model skills. Unlike typical autonomous agents that can perform any action, E2LLM functions as a perception layer, providing language models with structured browser senses and a limited set of gated actuators. The SiFR format is designed to be deterministic and token-efficient, ranking nodes by salience and flattening them into a relational model, distinguishing it from DOM dumps and accessibility trees. The system includes nine tools, with five dedicated to read-only perception and four for interaction, ensuring that state-changing actions are narrowly defined and can be gated for user confirmation.

IMPACT Provides a structured, deterministic way for LLMs to perceive and interact with web pages, potentially improving reliability in browser-based AI tasks.

    🧩 Runtime Snapshots #19 - We Opened the Format.

    <p>Most things that ship under "browser MCP" are the same thing wearing different names: an autonomous agent with a do-anything tool, pointed at your browser, told to figure it out. The pitch is capability. The unspoken cost is that a runtime which can do anything can be steered …
