We've revised the draft composer actions spec after implementing the first prototypes.

The main change is using postMessage for form-to-client communication, but we've also added a more detailed tech spec.

I'm very excited about these, but embedded forms open a new security/safety surface that clients need to approach carefully. 

I've heard from a lot of builders eager to create composer actions and appreciate your patience while we work out the right approach. If we get it right, it's a foundation for a whole class of new programmable social primitives.

Looking for broad feedback on the latest composer actions spec. Embedded content and two way client-app postMessage communication could enable a bunch of new programmable primitives, but it's important to get it right.

I'm eth newbie..just learning

I could easily add my no code builder (including image upload) as composer action. Is there something where I can debug/test it? And ist it allowed to change site via get request within the iframe? So that just at the end we need to post the final cast message? (Then a kind of wizard for generating a frame is possible; or if there already existing frames you could search and select one)

Working on dev tools, will send you a link to the coordination chat.
