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.

I think we're just one step away from creating a miniapp. By adding fc:frame:button:$idx:app_url within the frame, along with this postMessage, I'll be able to develop web games or more interactive content.

Perhaps mini apps can already be implemented through composer actions? It's just missing a more convenient entry point for mini apps.

As long as the frames is used as an entry point for the app, or the actions is used as an entry point, both options are very smooth.
