OKF (Open Knowledge Format) is portable knowledge: Markdown files with YAML frontmatter that both humans and agents read from one source. This gem is the Ruby-native way to work with it. Its companion agent skill authors and curates a bundle. The `okf` command-line tool validates the result for v0.1 (§9) conformance, lints its curation quality, and answers questions about it: ranked full-text search, and a progressive-disclosure map that reads a large bundle a directory at a time rather than loading it whole. `okf server` opens it as an interactive knowledge graph and `okf render` bakes that same page into one self-contained HTML file you can host anywhere. A per-user registry names your bundles, so every verb reaches them by @slug from any directory and one search can span them all. Everything the CLI does also runs in-process through a library API (OKF::Bundle and friends), and the graph server is a mountable Rack app. It adds no service to your stack: rack, webrick and minifts are the only runtime dependencies, and it runs on every Ruby since 2.4.

Ovto is a client-side framework for Opal. You can write single-page apps with Ruby.

Rack::Debug is a middleware that provides a simple interface to ruby-debug. Helps debug apps running in Passenger.

Rack::Debug adds a middlerware interface to ruby-debug http://github.com/github/rack-debug

Provides a policy for frozen rack middleware.

This middleware acts as a spam trap. It inserts, into every outputted <form>, a text field that a spambot will really want to fill in, but is actually not used by the app. The field is hidden to humans via CSS, and includes a warning label for screenreading software.

A Rack middleware for providing JSON-P support.

Rack middleware that provides authentication based on JSON Web Tokens.

Rack-P3p is rack middleware for inserting P3P headers into apps. This will allow your application to serve cookies to IE when in an iframe. It will also pull off the cookie on 304 responses, since IE does not like the cookie then.
