About

Actionbook is an open source “action playbook” platform that gives AI agents up-to-date manuals and a relevant Document Object Model (DOM) structure so they can operate any website instantly and reliably without having to parse full pages or guess element selectors, dramatically reducing execution time and token costs while improving resilience against dynamic or complex web apps. It provides pre-built action manuals with precise verified selectors so agents hit the right elements every time instead of consuming large context windows to explore page structures, and supports modern web technologies such as virtual DOM, streaming components, and single-page applications, so traditional scraping or brittle automation isn’t required. Actionbook’s approach saves up to 100× in token usage, accelerates agent execution, and works universally with any large language model, agent framework, and browser automation tool, enabling developers to integrate it with their existing stacks.

About

Manifest by Omfang is an action layer for AI agents that turns any webpage into a structured map of what an agent can actually do. Developers send a URL to the Manifest API and receive clean JSON describing the page state, available buttons, forms, inputs, navigation links, required fields, and dependencies between actions. Manifest loads the page in a real Chromium browser after JavaScript runs, reads the accessibility tree used by screen readers, and cross-references it with the underlying DOM to capture details the accessibility layer can miss, including input types, placeholders, disabled states, and prerequisites for submission. Once actions are identified, their locators are resolved deterministically rather than generated by a model; ambiguous matches are marked uncertain instead of guessed. This gives agents a machine-readable interface for reasoning about what to click, fill, or submit without relying on screenshots, brittle CSS paths, etc.
