mod.rs

1//! Configuration module for A3S Code
2//!
3//! Provides configuration for:
4//! - LLM providers and models (defaultModel in "provider/model" format, providers)
5//! - Queue configuration (a3s-lane integration)
6//! - Search configuration (a3s-search integration)
7//! - Directories for dynamic skill and agent loading
8//!
9//! Configuration is loaded from ACL-compatible files or strings.
10//! Existing `.acl` config filenames are still accepted for compatibility.
11//! JSON support has been removed.
