+//! Cursor headless non-interactive CLI provider.
+//!
+//! Integrates with Cursor's headless CLI mode, spawning the `cursor` binary
+//! as a subprocess for each inference request. This allows using Cursor's AI
+//! models without an interactive UI session.
+//!
+//! # Usage
+//!
+//! The `cursor` binary must be available in `PATH`, or its location must be
+//! set via the `CURSOR_PATH` environment variable.
+//!
+//! Cursor is invoked as:
+//! ```text
+//! cursor --headless --model <model> -
+//! ```
+//! with prompt content written to stdin.
+//!
+//! If the model argument is `"default"` or empty, the `--model` flag is omitted
+//! and Cursor's own default model is used.
+//!
+//! # Limitations
+//!
+//! - **Conversation history**: Only the system prompt (if present) and the last
+//!   user message are forwarded. Full multi-turn history is not preserved because
+//!   Cursor's headless CLI accepts a single prompt per invocation.
+//! - **System prompt**: The system prompt is prepended to the user message with a
+//!   blank-line separator, as the headless CLI does not provide a dedicated
+//!   system-prompt flag.
+//! - **Temperature**: Cursor's headless CLI does not expose a temperature parameter.
+//!   Only default values are accepted; custom values return an explicit error.
+//!
+//! # Authentication
+//!
+//! Authentication is handled by Cursor itself (its own credential store).
+//! No explicit API key is required by this provider.
+//!
+//! # Environment variables
+//!
+//! - `CURSOR_PATH` — override the path to the `cursor` binary (default: `"cursor"`)
