Fourteen tools for multi-agent software development: messaging and file leases, issue graphs, session search, command safety, and tmux orchestration. I started building the stack in October 2025. Join the Flywheel Hub Discord (~930 members), read the full guide, or start with the introductory guide.

Asupersync is my spec-first, cancel-correct, capability-secure async runtime for Rust. Its API makes task ownership, cancellation, cleanup, and effect authority explicit. It supplies shared concurrency and evidence infrastructure across much of FrankenSuite, including common kernel, decision, and evidence crates.

Asupersync combines an executor, lifecycle contracts, capability controls, and deterministic concurrency tests. FrankenTerm uses it as its production async runtime; FrankenSearch threads Cx through index construction; FrankenSQLite and FrankenGit build their RaptorQ durability components on its encoding and decoding code; and FrankenEngine enables the shared kernel, decision, and evidence crates by default.

The FrankenSuite spans databases, terminals, numerical computing, media, graphs, and simulation. Many projects are clean-room Rust reimplementations that preserve important APIs, file formats, and protocols while adding memory safety, deterministic execution, concurrent data structures, or repairable storage.
