cargo-machete found unused dependencies in crates/goose-sdk/Cargo.toml:

goose-sdk -- ./crates/goose-sdk/Cargo.toml:
    async-trait
    schemars
    serde

Either remove them from [dependencies] in crates/goose-sdk/Cargo.toml, or if they're actually needed (e.g. re-exported or used by macros), suppress the false positive by adding to Cargo.toml:

[package.metadata.cargo-machete]
ignored = ["async-trait", "schemars", "serde"]
