The approach lets a capability implemented in Rust be reused across languages without reinventing validation, approvals, or tracing. The developer recommends starting with the protocol and tests before layering on language-specific ergonomics.", "body_md": "In most real-world systems, “AI agents” sit on top of a polyglot stack:\n\nIf your capability model only really exists in one language, you end up with:\n\nA more sustainable pattern is to treat the **capability protocol** as the primary artifact and the language SDKs as implementations.\n\nConcretely:\n\nNow a capability implemented in Rust can be:\n\n…without reinventing validation, approvals, or tracing.\n\nIf you are designing your own internal runtime, consider starting with the protocol and tests first, and only then layering language-specific ergonomics on top.
