Library.
Every primitive of the agent economy. 110 assets across six families: plugins for the surfaces your agents touch, extensions for the kernel itself, guards and policies for what they're allowed to do, integrations for evidence and settlement, and contracts for the protocol surface beneath it all.
Plugins. Drop-in adapters that connect chio to specific agents, IDEs, frameworks, and runtimes.

Author your own.
Plugins, guards, policies, contracts.
Every chio asset is open-spec. Author plugins in any of our four SDKs, write guards as portable WASM, and publish policies as YAML manifests. The library accepts community submissions reviewed for safety and signed before listing.
