objectiveai-cli 2.1.1

//! `functions list <source>` — enumerate functions from a given source.
//! Streams one `ResponseItem` per function. Sources:
//!
//! - `Favorites` — on-disk function favorites (no HTTP).
//! - `Filesystem` / `Objectiveai` / `Mock` — delegates to the SDK's
//!   `list_functions` HTTP endpoint with the matching
//!   `ListFunctionsSource`.
//! - `All` — favorites + filesystem + objectiveai, **de-duplicated**:
//!   favorites first, filesystem items skipping anything already
//!   covered by a favorite, then ObjectiveAI items skipping anything
//!   covered by a favorite or a filesystem item. Filesystem and
//!   ObjectiveAI fetches run concurrently.
