//! Built-in transforms for the provider middleware chain. //! //! Each transform implements [`crate::provider::Transform`] and can be //! composed into a [`chain::TransformChain`]. //! //! # Available Transforms //! //! | Transform | Purpose | //! |-----------|---------| //! | [`NamespaceTransform`] | Prefix tool names (e.g. `gmail_*`) | //! | [`FilterTransform`] | Allow/deny tools by exact name or glob pattern | //! | [`RenameTransform`] | Rename individual tools | //! | [`ResponseTransform`] | Project/redact response fields | //! //! # Transform Pipeline Order //! //! Fixed order within a `TransformChain`: //! `namespace → filter → auth → response` pub mod chain; pub mod filter; pub mod namespace; pub mod rename; pub mod response; pub use filter::FilterTransform; pub use namespace::NamespaceTransform; pub use rename::RenameTransform; pub use response::ResponseTransform;
