//! Extension traits for ApplicationContext to provide ergonomic access to chain-specific clients
//!
//! These traits should be implemented in the respective chain-specific crates
//! (riglr-solana-tools, riglr-evm-tools, etc.) to provide type-safe, convenient
//! access methods for their clients.

use crate::ToolError;
use std::sync::Arc;

/// Example trait that should be implemented in riglr-solana-tools
///
/// # Example Implementation (in riglr-solana-tools/src/lib.rs):
/// ```rust,ignore
/// use riglr_core::provider::ApplicationContext;
/// use riglr_core::provider_extensions::SolanaAppContextProvider;
/// use riglr_core::ToolError;
/// use solana_client::rpc_client::RpcClient as SolanaRpcClient;
/// use std::sync::Arc;
///
/// impl SolanaAppContextProvider for ApplicationContext {
///     fn solana_client(&self) -> Result<Arc<SolanaRpcClient>, ToolError> {

/// use riglr_core::provider_extensions::AppContextExtension;
/// use riglr_core::ToolError;
