Product Idea from this Signal

A CLI tool that translates skills, memory files, and channel configs between OpenClaw, ZeroClaw, and Nanobot so you can run the same agent on any runtime

70.6k ▲

Three agent runtimes now have 30K+ GitHub stars each (OpenClaw 355K, ZeroClaw 31K, Nanobot 30K). Developers invest weeks configuring skills, memory, and channels for one runtime, then get locked in when that runtime ships a breaking update or a CVSS 8.8 CVE. Each runtime uses different config formats (OpenClaw YAML + SOUL.md, ZeroClaw TOML + IDENTITY.md, Nanobot Python configs). This tool reads your agent setup from any of the three, translates it to the other two, and validates the output against the target runtime schema.
