# kernex-core
Foundation types, traits, and error handling for the [Kernex](https://github.com/kernex-dev/kernex) AI agent runtime.
This crate is the dependency-free root of the workspace. It defines:
- `Provider` and `HookRunner` traits — the integration points every other crate builds on
- `Context`, `Request`, `Response`, `CompletionMeta` — the shared message types
- `KernexError` — the unified error enum
- `PermissionRules` — declarative tool allow/deny patterns
- `GuardrailRunner` — pre/post-message safety hooks
- Built-in helpers for sanitization, pricing tables, and UTF-8 boundary handling
You usually do not depend on `kernex-core` directly. Pull in [`kernex-runtime`](https://crates.io/crates/kernex-runtime) (or the [`kernex`](https://crates.io/crates/kernex) umbrella) and its public surface re-exports what you need.
