Skill authoring and runtimes

Design a skill contract, choose a bounded runtime, and validate packages before execution.

Start with the contract

A skill manifest names the runtime, input contract, resources, and requested capabilities. Keep this contract stable when moving an implementation between Node.js, Python, WASM, or native Rust.

WASM skills

Wasmtime executes portable modules through WASI Preview 1. Host access remains explicit, which makes WASM suitable when portability and a narrow sandbox matter more than ecosystem breadth.

Native Rust operations

Trusted native operations are registered by name inside the Rust workspace. They trade isolation and hot-swappability for direct integration and should remain limited to reviewed system work.

Validate and release

Validate the manifest and input schema
Exercise the skill in its actual worker runtime
Review requested capabilities and failure behavior
Refresh the Skill Book and confirm the new checksum
Inspect worker health and ledger events after execution
