Asupersync Mega Skill

Asupersync is a spec-first, cancel-correct, capability-secure async runtime for Rust. Not a Tokio wrapper -- a complete replacement with stronger guarantees around structured concurrency, obligation tracking, deterministic testing, and capability security.

This skill is primarily for agents integrating Asupersync into other projects or extracting maximum architectural leverage from it in greenfield systems. It also covers repo-internal work when that is the actual task.

For codebase orientation, types, module map, and workspace layout see SOURCE-MAP.md.

Quick Orient

Minimal bootstrap:

use asupersync::runtime::RuntimeBuilder;

fn main() -> Result<(), asupersync::Error> {
    let rt = RuntimeBuilder::current_thread().build()?;
    rt.block_on(async {
        let cx = asupersync::Cx::for_request();
